Description

The technology disclosed in this specification relates to an inspection management method and an inspection display member that display whether or not a slinging wire rope has been inspected during a target period.

Conventionally, as an inspection management method for displaying whether or not a sling wire rope has been inspected during a target period (for example, each week of the month), a color (called an "inspection color") corresponding to each target period has been used. A method is known in which an attached inspection display member (for example, vinyl tape) is installed on a sling wire rope (for example, Patent Document 1).

Utility model registration No. 3224437

Specifically, in the conventional inspection management method described above, inspection colors (for example, green, yellow, (red, white) and prepare inspection display members with each inspection color. Then, when the sling wire rope is inspected at each target period, an inspection display member with an inspection color corresponding to the corresponding target period is installed on the sling wire rope. At this time, the already installed inspection display member is removed (except for the first inspection), and a new inspection display member is installed. Therefore, this inspection management method required a heavy workload.

This specification discloses a technique that can solve the above-mentioned problems.

The technology disclosed in this specification can be realized, for example, as the following form.

(1) The inspection management method disclosed in this specification is an inspection management method that displays whether or not the slinging wire rope has been inspected during the target period, and includes the following first step and second step. Be prepared. The first step is to provide an inspection display member including a plurality of colored parts with inspection colors, each colored part being arranged in a first direction, and the inspection color of each colored part being set to the adjacent colored part. The sling wire is arranged so that at least a portion of each colored portion is covered by the colored portion located next to the colored portion in a second direction opposite to the first direction. This is the process of wrapping it around a rope. The second step is a step of removing the outermost colored portion when the inspection at each target period is performed. In this inspection management method, the work of wrapping the inspection display member around the slinging wire rope is done only once, and when the inspection at each target period is carried out, a part of the inspection display member (the outermost colored part) is removed. Just that is enough. Therefore, according to the present inspection management method, the workload of inspection management (displaying whether or not an inspection has been performed in a target period) can be reduced compared to conventional inspection management methods.

(2) In the above inspection management method, the inspection color of each colored portion of the inspection display member may be different from the inspection color of any other colored portion. In this inspection management method, the inspection color of each colored part of the inspection display member is different from the inspection color of any other colored part, so a unique color is used as the inspection color of each colored part for each target period. Can be set. Therefore, according to this inspection management method, it is possible to grasp the target period corresponding to the inspection color of the outermost colored part more accurately (or more limitedly) than in a configuration in which multiple colored parts are given the same inspection color. be able to.

(3) In the inspection management method, each of the colored sections is located at both ends of the inspection colored section to which the inspection color is attached and the third direction perpendicular to the first direction with respect to the inspection colored section. A configuration including a pair of white parts may also be adopted.

If the entire inspection display member including the pair of white parts of the colored part is of a single color (inspection color), the outermost colored part of the inspection display member wrapped around the sling wire rope and the inner Due to misalignment in the third direction with one or more colored parts, the inner colored part may be visible along with the outermost colored part, and this may cause the inspection color ( It may be difficult to determine the inspection color of the outermost colored part.

In contrast, in this inspection management method, the outermost colored part of the inspection display member wrapped around the slinging wire rope can be seen in its entirety along with the inspection color attached to the inspection colored part. (In other words, two white parts are visible). On the other hand, when the outermost colored part of the inspection display member wrapped around the slinging wire rope is misaligned in the third direction with one or more inner colored parts, the inner colored part The entire pair of white parts cannot be seen (usually only one of the pair of white parts is visible). Therefore, the outermost colored portion and the inner colored portion can be easily distinguished. Therefore, according to this inspection management method, even if the outermost colored part of the inspection display member wrapped around the slinging wire rope is misaligned with one or more inner colored parts, the outermost colored part You can easily understand the inspection color of the section.

(4) In the above-mentioned inspection management method, the inspection display member is arranged so that the dimension in the first direction of one end colored portion, which is the colored portion located at one end in the first direction, is the same as that of the other colored portion. 1, and the first step may be a step of first winding the one-end colored portion around the sling wire rope.

If the dimension of the colored portion at one end in the first direction is the same as the dimension of the colored portion at the other end, the colored portion at one end that is first wound around the sling wire rope may not be sufficiently fixed in the first step. , the inspection display member may not be sufficiently fixed to the sling wire rope.

On the other hand, in this inspection management method, because the dimension of the colored part at one end in the first direction is longer than the dimension of the colored part at the other end, the dimension in the first direction of the colored part at one end is longer than that of the other colored part. Compared to a configuration with the same dimensions, the contact area between the colored portion at one end and the slinging wire rope becomes larger. Further, if the dimensions of the other colored portions are approximately the length of the outer circumference of the slinging wire rope, the part of the colored portion at one end whose dimension in the first direction is longer than the length of the outer circumference is the same as that of the other colored portion at one end. will come into contact with the parts. This part of the colored end is (often) more firmly fixed than the part that contacts the slinging wire rope. For these reasons, according to the present inspection management method, in the first step, the colored part at one end that is first wrapped around the slinging wire rope is more firmly fixed, thereby making the inspection display member more firmly attached to the slinging wire rope. It can be fixed to

(5) In the above inspection management method, the inspection display member includes a first colored part group that is a combination of n colored parts (n is 3 or more) arranged in the first direction, and a first colored part group that is a combination of the colored parts arranged in the first direction; a second colored part group that is a combination of parts, is located next to the first colored part group in the second direction, and satisfies the following condition (C1); It is good also as a structure provided with.

Condition (C1): Identification numbers i (i=1, 2, ..., n) for identifying the colors of the n colored parts included in the first colored part group are set in the first direction. When the counted ordinal number is used, the second group of colored parts is selected from combinations formed by all the identification numbers i satisfying the formula: n/2+2≦i≦n, in descending order from n. The colored parts of the inspection color identified by the combination of the identification numbers i formed by selecting a part or the whole are arranged in ascending order of the identification number i.

If the inspection display member does not include the second colored part group but only includes the first colored part group, the target period corresponding to the colored part of the first colored part group (for example, from the first week to the first 4 weeks) is the unit cycle of the inspection management schedule, this inspection management method starts from the target period in the latter half of the time series of the unit cycle (for example, the 4th week) (that is, the first When carrying out the process), the colored parts corresponding to the target period in the first half are not used and are wasted, resulting in a large loss of inspection display members.

On the other hand, the present inspection management method includes the second colored portion group described above. When applied to inspection management in which the target period (for example, 1st week to 4th week) corresponding to the colored part of the first colored part group is a unit cycle of the inspection management schedule, the second colored part group The inspection color of the colored part corresponds to the target period in the latter half of the time series of the unit cycle (for example, the fourth week). In this inspection management method, when this inspection management method is started (that is, the first step is performed) at the target period in the latter half of the time series of the unit cycle, in the first step, the time series of the unit cycle is The second step is performed by winding the wire rope around the sling wire rope so that the first colored portion included in the second colored portion group corresponding to the second half of the target period is visible. In addition, in the second step, after all the colored parts included in the second colored part group are removed, each colored part in the first colored part group is removed to remove the colored parts at the beginning of the unit cycle (the first Inspection and management will be carried out as usual from the end of the week (week 4) to the end (week 4). As a result, inspection management can be performed while reducing loss of the inspection display member compared to a configuration in which the inspection display member does not include the second group of colored parts and only includes the first group of colored parts.

(6) The inspection display member disclosed in this specification is an inspection display member that displays whether or not the slinging wire rope has been inspected during the target period, and includes a plurality of colored parts with inspection colors, The colored parts are arranged in a first direction, the inspection color of each colored part is different from the inspection color of the adjacent colored part, and each colored part is arranged in a direction opposite to the first direction. The sling wire rope is wrapped around the sling wire rope so as to be covered by the colored portion located next to the sling wire rope in two directions. According to this inspection display member, effects similar to those obtained by the inspection management method described in (1) above can be obtained. That is, according to the present inspection display member, the work burden of inspection management can be reduced compared to the above-mentioned conventional inspection display member.

Note that the technology disclosed in this specification can be realized in various forms, for example, in the form of an inspection management method, an inspection display member, etc.

In the inspection management method of the present embodiment, as an example, the inspection color indicates that the sling wire rope Wr has been inspected during the target period, and each inspection color is assigned to the first week Sn1, which is the target period of inspection management. , second week Sn2, third week Sn3, and fourth week Sn4. In other words, in the inspection management method of this embodiment, one inspection display member 20 displays the first week Sn1, second week Sn2, third week Sn3, and fourth week Sn4 (one month) of an arbitrary target month. The system was designed to conduct inspections and management of (minutes). Specifically, the inspection color (green) attached to the inspection color section 221 of the second coloring section 22 corresponds to the first week Sn1, and the inspection color (green) attached to the inspection color section 231 of the third coloring section 23 corresponds to the first week Sn1. The inspection color (yellow) corresponds to the second week Sn2, and the inspection color (red) attached to the inspection color section 241 of the fourth colored section 24 corresponds to the third week Sn3, The inspection color (white) attached to the inspection color section 251 of the fifth colored section 25 corresponds to the fourth week Sn4. In addition, the inspection color (white) attached to the inspection color section 211 of the first coloring section 21 is used when inspection management is started from the fourth week Sn4 of the month preceding the above-mentioned month, so that it is used for the above-mentioned target month. It corresponds to Sn4 of the fourth week of the previous month. In addition, in order to use the inspection color (white) attached to the inspection color section 211 of the first colored section 21 when inspection management is started from the fifth week of the month preceding the above-mentioned target month, It may also correspond to the fifth week of the previous month.

As shown in FIG. 2, in the inspection management method of this embodiment, first, the inspection display member 20 is covered with at least a portion (for example, the entirety) of each colored portion by a colored portion located next to it in the negative direction of the X-axis. Wrap it around the slinging wire rope Wr so that the sling wire rope Wr is wrapped (S11). Hereinafter, the step S11 will be referred to as "first step S11." In the first step S11 of the present embodiment, first, the fifth colored portion 25 located at one end in the positive direction of the X-axis is wound around the sling wire rope Wr.

FIG. 3 shows the side configuration of the slinging wire rope Wr and the inspection display member 20 after the first step S11. It should be noted that illustration of parts other than the tip of the slinging wire rope Wr is omitted. FIG. 4 shows a cross-sectional configuration of the slinging wire rope Wr and the inspection display member 20 at the position IV-IV in FIG. 3.

As shown in FIGS. 3 and 4, after the first step S11, the first colored portion 21 is located at the outermost side and is therefore exposed. Further, as shown in FIG. 4, the second colored portion 22 is covered by the first colored portion 21 located next to it in the negative direction of the X-axis (see FIG. 1). The third colored part 23 is covered by the second colored part 22 located next to it in the negative direction of the X-axis (see FIG. 1). The fourth colored part 24 is covered by the third colored part 23 located next to it in the negative direction of the X-axis (see FIG. 1). The fifth colored part 25 is covered by the fourth colored part 24 located next to it in the negative direction of the X-axis (see FIG. 1). Therefore, the second colored part 22, . . . , the fifth colored part 25 are not visible, and only the first colored part 21 is visible.

Next, when the inspection at each target period is performed, the outermost colored portion is removed (S12). Hereinafter, the step S12 will be referred to as "second step S12."

That is, when the slinging wire rope Wr is inspected in the first week Sn1, the first colored portion 21 exposed due to being located at the outermost side is removed. FIG. 5 is a diagram showing a cross-sectional configuration when the first colored portion 21 is removed from the slinging wire rope Wr and the inspection display member 20 shown in FIG. 4. As shown in FIG. 5, by removing the first colored portion 21 as described above, the second colored portion 22 is exposed at the outermost position. Thereby, the person who carries out the main inspection management can see the inspection color (green) attached to the inspection color section 221 of the second colored section 22.

Similarly, when the slinging wire rope Wr is inspected in the second week Sn2, the second colored portion 22 exposed due to being located at the outermost side is removed. As a result, the third colored portion 23 is located at the outermost position and exposed. Thereby, the person who carries out the main inspection management can see the inspection color (yellow) attached to the inspection color section 231 of the third colored section 23.

Similarly, in the third week Sn3, the fourth colored part 24 is located at the outermost position by removing the third colored part 23, and in the fourth week Sn4, the fourth colored part 24 is removed. By doing so, the fifth colored portion 25 is located at the outermost position. As a result, the person performing the main inspection management can check the inspection color (red) attached to the inspection color section 241 of the fourth colored section 24 and the inspection color section 251 of the fifth colored section 25. You can see the inspection color (white). In addition, when continuing the same inspection management in the month following the above-mentioned target month, for example, when the inspection of the first week Sn1 is performed, the first step S11 is performed, and then the second step S12 is performed. Just do it.

As described above, in the inspection management method of the present embodiment, it is possible to determine whether or not the sling wire rope Wr has been inspected at the target period (first week Sn1, second week Sn2, third week Sn3, fourth week Sn4). Is displayed.

In addition, in the inspection display member 20 of this embodiment, inspection management is started from the fourth week Sn4 (or the fifth week of the previous month) of the month preceding the target month (that is, the first step S11 is performed). Furthermore, it is also possible to perform inspection management from the first week Sn1 to the fourth week Sn4 of the target month. At this time, for example, the first step S11 is performed when the inspection in the fourth week Sn4 of the previous month is performed, and at each target time of the target month (first week Sn1, ..., fourth week Sn4) The second step S12 may be performed as described above.

In the following, the combination of colored parts consisting of the second colored part 22, the third colored part 23, the fourth colored part 24, and the fifth colored part 25 will be referred to as "first colored part group Cg1". ”, and the combination of colored portions including the first colored portions 21 (that is, the first colored portions 21) is referred to as a “second colored portion group Cg2”. Note that the first colored part group Cg1 includes colored parts (colored parts) with inspection colors indicating the target period (in this embodiment, the first week Sn1 to the fourth week Sn4) corresponding to the unit cycle of the inspection management schedule. In this embodiment, it is a combination of the second colored portion 22, . . . , and the fifth colored portion 25). The inspection color of the colored part of the second colored part group Cg2 is the colored part (in this embodiment This is the combination of the first colored portion 21).

As described above, when the first colored part group Cg1 and the second colored part group Cg2 are used, the inspection display member 20 of this embodiment can be said to have the following configuration. That is, the inspection display member 20 of the present embodiment is a combination of a first colored part group Cg1, which is a combination of n (n is 3 or more) colored parts arranged in the positive direction of the X-axis, and a colored part. The second coloring part group Cg2 is located next to the first coloring part group Cg1 in the negative X-axis direction and satisfies the following condition (C1). .
Condition (C1): Identification numbers (i = 1, 2, ..., n) that identify the inspection colors of n colored parts included in the first colored part group Cg1 are counted in the positive direction of the X axis. When it is an ordinal number,
The second colored part group Cg2 is constructed by selecting part or all of the combinations formed by all identification numbers i satisfying the formula: n/2+2≦i≦n in descending order from n. The colored parts of the inspection colors identified by the combination of identification numbers i are arranged in ascending order of the identification numbers i.

In this embodiment, n is 4, and the identification numbers (i=1, 2, ..., 4) for identifying the inspection colors of the four colored parts included in the first colored part group Cg1 are When the ordinal number is counted in the positive direction of the axis, the second colored part group Cg2 is the fifth colored part to which the inspection color (white) is attached, which is identified by the identification number i (4) that satisfies the above formula. 25 (combination constituted by), the above condition (C1) is satisfied.

Further, in the present embodiment, the inspection color assigned to each of the plurality of (four in this embodiment) colored parts included in the first colored part group Cg1 is different from the inspection color of the adjacent colored part. ing.

A-4. Effects of this embodiment:
As explained above, the inspection management method of the present embodiment allows inspection of the slinging wire rope Wr at target periods (in the present embodiment, the first week Sn1, the second week Sn2, the third week Sn3, and the fourth week Sn4). This is an inspection management method for displaying whether or not the inspection has been carried out, and includes the following first step S11 and second step S12. The first step S11 includes a plurality of colored sections with inspection colors, and the inspection color of each colored section (first colored section 21, ..., fifth colored section 25) is the same as that of the adjacent colored section. The inspection display member 20 having a different inspection color is slung over a wire rope so that at least a portion of each colored portion is covered by a colored portion located next to the X-axis negative direction (the opposite direction to the X-axis positive direction). This is the process of winding it around Wr. The second step S12 is a step of removing the outermost colored portion when inspection is performed at each target period. In the inspection management method of this embodiment, the work of winding the inspection display member 20 around the slinging wire rope Wr is done only once, and when the inspection is carried out at each target period, a part of the inspection display member 20 (the outermost All you need to do is remove the colored part). Therefore, according to the inspection management method of this embodiment, the workload of inspection management (displaying whether or not an inspection has been performed in a target period) can be reduced compared to the conventional inspection management method.

In addition, in the inspection management method of this embodiment, each colored portion is arranged in the Y-axis direction (X-axis positive direction) with respect to the inspection colored portions (211, ..., 251) to which the inspection color is attached A pair of white portions (212 and 213, . . . , 252 and 253) located at both ends of a direction perpendicular to

In a configuration in which the entire colored part of the inspection display member 20 including the pair of white parts is of a single color (inspection color), the outermost colored part of the inspection display member 20 wound around the sling wire rope Wr. , the inner colored part may be visible together with the outermost colored part due to the misalignment with one or more inner colored parts. It may be difficult to determine the color (inspection color of the outer colored part).

On the other hand, in the inspection management method of the present embodiment, for the colored part appearing on the outermost side of the inspection display member 20 wound around the slinging wire rope Wr, a pair of white The entire area is visible (that is, two white areas are visible). On the other hand, when the outermost colored part of the inspection display member 20 wound around the slinging wire rope Wr is misaligned with one or more inner colored parts, the inner colored part becomes a pair of white. The whole part is not visible (usually only one of the pair of white parts is visible). Therefore, the outermost colored portion and the inner colored portion can be easily distinguished. Therefore, according to the inspection management method of the present embodiment, even if the position of the outermost colored part of the inspection display member 20 wound around the slinging wire rope Wr and one or more inner colored parts is misaligned, , the inspection color of the outermost colored part can be easily grasped.

In addition, in the inspection management method of the present embodiment, the inspection display member 20 is connected to the X-axis of the fifth colored portion 25, which is a colored portion located at one end in the positive direction of the X-axis (hereinafter referred to as “one-end colored portion”). The dimension in the positive direction is longer than the dimension in the X-axis positive direction of the other colored portions, and the first step S11 is a step of first winding one end of the colored portion around the slinging wire rope Wr.

In a configuration in which the dimension in the X-axis positive direction of the colored portion at one end (fifth colored portion 25) is equal to the dimension of the other colored portion, it is first wound around the sling wire rope Wr in the first step S11. If the colored portion at one end is not sufficiently fixed, the inspection display member 20 may not be sufficiently fixed to the sling wire rope Wr.

On the other hand, in the inspection management method of the present embodiment, since the dimension in the positive direction of the X axis of the colored part at one end (fifth colored part 25) is longer than the dimensions of the other colored parts, Compared to a configuration in which the dimension in the positive axis direction is the same as the dimension of the other colored portions, the contact area between the one end colored portion and the sling wire rope Wr becomes larger. Furthermore, if the dimensions of the other colored portions are approximately the length of the outer circumference of the slinging wire rope Wr, the part of the colored portion at one end whose dimension in the positive direction of the X-axis is longer than the length of the outer circumference is the other colored portion at one end. will come into contact with the part. The part of the one-end colored part is fixed more firmly than the part that contacts the slinging wire rope Wr (often). For these reasons, according to the inspection management method of the present embodiment, in the first step S11, the colored portion at one end that is first wound around the slinging wire rope Wr is more firmly fixed, and thereby the inspection display member 20 is slinged. It can be more firmly fixed to the wire rope Wr.

In addition, the inspection display member 20 of the present embodiment includes a first colored part group Cg1, which is a combination of n colored parts (n is 3 or more) arranged in the positive direction of the X-axis, and a combination of colored parts. A second colored part group Cg2 is provided, which is located next to the first colored part group Cg1 in the negative X-axis direction and satisfies the following condition (C1).
Condition (C1): Identification numbers (i = 1, 2, ..., n) for identifying the inspection colors of n colored parts included in the first colored part group Cg1 are counted in the positive direction of the X axis. When it is an ordinal number,
The second colored part group Cg2 is constructed by selecting a part or the whole in descending order from n from combinations made up of all identification numbers i satisfying the formula: n/2+2≦i≦n. The colored parts of the inspection colors identified by the combination of identification numbers i are arranged in ascending order of the identification numbers i.

In a configuration in which the inspection display member 20 does not include the second colored part group Cg2 and only includes the first colored part group Cg1, the target period corresponding to the colored part of the first colored part group Cg1 (for example, the first colored part group When applied to inspection management in which the unit cycle of the inspection management schedule is 1 week to 4th week), the inspection management method of this embodiment is applied from the target period in the latter half of the time series of the unit cycle (for example, the 4th week). When starting (that is, performing the first step), the colored portions corresponding to the first half of the target period are not used and are wasted, resulting in a large loss of the inspection display member 20.

In contrast, the inspection management method of this embodiment includes the second colored portion group Cg2 described above. When applied to inspection management in which the target period (for example, the first week to the fourth week) corresponding to the colored part of the first colored part group Cg1 is a unit cycle of the inspection management schedule, the second colored part group The inspection color of the colored portion of Cg2 corresponds to the target period in the latter half of the time series of the unit cycle (for example, the fourth week). In the inspection management method of this embodiment, when the inspection management method of this embodiment is started (that is, the first step S11 is performed) at the target time in the latter half of the time series of the unit cycle, the first step S11 In this step, the first colored part included in the second colored part group Cg2 corresponding to the target period in the second half of the time series of the unit cycle is wound around the sling wire rope Wr so that the first colored part included in the second colored part group Cg2 is visible, and the second step S12 is performed. In addition, in the second step, after removing all the colored parts included in the second colored part group Cg2, by removing each colored part of the first colored part group Cg1, the first ( Inspection and management will be carried out as usual from the first week) to the last week (fourth week). As a result, inspection management can be performed while reducing loss of the inspection display member 20 compared to a configuration in which the inspection display member 20 does not include the second coloring section group Cg2 and only includes the first colored section group Cg1. Can be done.

Note that in this embodiment, the inspection color assigned to each of the plurality of (four in this embodiment) colored parts included in the first colored part group Cg1 is different from the inspection color of the adjacent colored part. (Except when the adjacent colored part is a colored part included in the second colored part group Cg2). In this configuration, a unique color can be set for each target period as the inspection color of each colored part included in the first colored part group Cg1. Therefore, according to the inspection management method of the present embodiment, the outermost It is possible to grasp the target period corresponding to the inspection color of the colored part.

B. Variant:
The technology disclosed in this specification is not limited to the above-described embodiments, and can be modified into various forms without departing from the gist thereof. For example, the following modifications are also possible.

For example, the inspection display member 20 of the above embodiment is a substantially rectangular sticker pasted on the mount 10, but the shape, material, etc. of the inspection display member of the present invention are limited to such aspects. isn't it. That is, the inspection display member of the present invention has the above-mentioned colored portion, and as long as it can be wrapped around the sling wire rope Wr. ) may also be used.

Further, although the inspection display device 100 of the above embodiment (or modified example, the same applies hereinafter) includes eight inspection display members 20, the number of inspection display members 20 is not particularly limited. For example, the inspection display device 100 may include ten inspection display members 20.

Further, although the inspection display member 20 of the above embodiment includes five colored parts (first colored part 21, . . . , fifth colored part 25), the number of colored parts is not particularly limited. It's not something you can do.

Further, in the above embodiment, the inspection color is a color corresponding to the target period when the inspection was performed, but if it is a color that indicates whether or not the sling wire rope Wr was inspected during the target period, this color may be used. It is not limited to such a definition. For example, in the above embodiment, the inspection color may be a color corresponding to the target time when inspection is to be performed next.

Further, in the above embodiment, the first colored part group Cg1 is a combination of n colored parts (n is 3 or more) arranged in the positive direction of the X-axis, and the second colored part group Cg1 is a combination of colored parts. A second colored part group Cg2, which is a group Cg2 and is located next to the first colored part group Cg1 in the negative X-axis direction, satisfies the above condition (C1). Specifically, the first colored part group Cg1 is composed of four colored parts (first colored part 21, ..., fourth colored part 4), and the second colored part group Cg2 is composed of four colored parts (first colored part 21, ..., fourth colored part 4). , one colored section (fifth colored section 25). However, in the above embodiment, as long as the first colored part group Cg1 and the second colored part group Cg2 satisfying the above condition (C1) are provided, the first colored part group Cg1 and the second colored part group The number of colored parts constituting Cg2 is not limited. For example, the first colored part group Cg1 may be composed of six colored parts, and the second colored part group Cg2 may be composed of two colored parts. Further, in the embodiment described above, the configuration may be such that the second coloring part group Cg2 is not provided and only the first coloring part group Cg1 is provided.

Furthermore, the above embodiment includes the first colored section 21 and the fifth colored section 25 whose inspection color is white; in other words, the inspection color of the plurality of colored sections is the same. Instead of such a configuration, in the above embodiment, the inspection color assigned to each colored portion (first colored portion 21, ..., fifth colored portion 25) is used for inspection of the adjacent colored portion. The configuration may be different from the color. In this configuration, since the inspection color of each colored part of the inspection display member 20 is different from the inspection color of any other colored part, a unique color is set as the inspection color of each colored part for each target period. can do. Therefore, according to the inspection management method of this embodiment, the target period corresponding to the inspection color of the outermost colored part can be more accurately (or more limitedly) than a configuration in which the same inspection color is assigned to a plurality of colored parts. can be understood.

Further, in the above embodiment, the dimension in the X-axis positive direction of the one end colored portion (in the above embodiment, the fifth colored portion 25) located at one end in the X-axis positive direction is different from the dimension in the X-axis positive direction. The length was longer than the dimension of the colored portion in the positive direction of the X-axis. Furthermore, the dimension in the X-axis positive direction of the one end colored portion located at one end in the X-axis positive direction was configured to be approximately twice the dimension in the X-axis positive direction of the other colored portions. Instead of such a configuration, in the above embodiment, the dimension in the X-axis positive direction of the one end colored portion located at one end in the X-axis positive direction is longer than the dimension in the X-axis positive direction of the other colored portions ( It is also possible to adopt a configuration in which the dimensions are other than approximately twice as large. Also in this configuration, the same effect as the above embodiment (the inspection display member 20 can be more firmly fixed to the slinging wire rope Wr) can be obtained. Further, in the above embodiment, the dimension in the X-axis positive direction of the one end colored portion located at one end in the X-axis positive direction may be less than or equal to the dimension in the X-axis positive direction of the other colored portion.

Moreover, the colored parts (first colored part 21, . . . , fifth colored part 25) of the inspection display member 20 of the above embodiment are the colored parts (211, . . . , 251) and a pair of white parts (212 and 213, . . . , 252 and 253). In the embodiment described above, the inspection display member 20 may not include a pair of white parts, but may include only an inspection colored part to which an inspection color is attached.
