Description

  The present invention relates to a fixing tool for maintaining and fixing a measuring tool that is placed on a road surface and measures the weight of a vehicle that rides on the road surface, and a vehicle weight measuring device including the fixing device.

  An apparatus for measuring the weight of cargo loaded on a vehicle together with the vehicle is generally called a truck scale, and is roughly classified into an embedded type and a portable type. Of these, the buried type is used to measure the weight of each vehicle at the time of receipt and shipment at the factory, and to perform receipt and shipment inspections.By moving the vehicle on this scale, the weight of the entire vehicle including cargo can be measured. taking measurement. Although the measurement is simple, there is a problem that the equipment is large because the entire vehicle is mounted and the measurement is carried out, and there is no choice but to be stationary. On the other hand, in the portable type, a small flat plate-like measuring instrument called Matt Scale (registered trademark) is placed on the road surface, and the load on the vehicle wheel that rides on it is measured in a running state (including low-speed running) or stationary state. And the weight of the whole vehicle is calculated by adding the load measurement result of each wheel. Although it is not for permanent installation and can be used arbitrarily by placing it at an appropriate place on the road surface when necessary, for example, when overloading vehicles are controlled, it requires time and labor to install it manually each time.

  The present invention is intended for the latter portable vehicle weight measuring device, and in particular, when the measuring instrument is installed on the road surface, it can be installed so that the measuring instrument does not move due to vibrations when the vehicle gets on and off. And a vehicle weight measuring device provided with the fixture. The measuring device itself is generally formed in a flat plate shape so that the measuring tool can be easily placed on the road surface, and the measuring method is to convert the strain of the gauge due to the load of the vehicle to be climbed into a change in electrical resistance value (for example, Patent Document 1)), or measuring the weight from the change in the electric capacity of the battery by being pressed by a load (see, for example, Patent Document 2). In the present invention, the flat measuring device is symmetrical, but the measuring method is not particularly limited.

  FIG. 4 shows an application example of such a portable vehicle weight measuring device (hereinafter also simply referred to as “measuring device”) in the prior art. In this specification, a device that detects the weight of a vehicle to be picked up and replaces it with a transmission means such as an electric signal is called a “measuring instrument”, and other auxiliary equipment including this measuring instrument is added to the vehicle weight. The entire device that enables the measurement of the above is called a “vehicle weight measuring device (hereinafter also simply referred to as“ measuring device ”)” to distinguish between them.

  In the example illustrated in FIG. 4, an outline of a measuring apparatus 100 that measures the vehicle weight by arranging eight measuring instruments 50 (50 a × 2, 50 b × 6) is shown. The measuring device 50 generally has a rectangular shape whose longitudinal direction is the direction orthogonal to the vehicle traveling direction indicated by the white arrow, and two of the measuring devices are arranged corresponding to a total of four axes in the longitudinal direction. The left and right positions in the figure correspond to the left and right wheels, respectively, and the three axes (B axis, C axis, D axis) from the bottom correspond to the rear wheel side of the vehicle. The axis (A axis) corresponds to the front wheel. In general, since the front wheels are single tires and the rear wheels are double tires, the front wheels are narrower than the rear wheels. The measuring device is divided into the right and left wheels so that the weight of one measuring device 50 is within the transportable range, the measuring device 50 has sufficient capacity, and there are no problems during transportation. It is not impossible to make this pair of left and right one elongated.

  In the case of a vehicle with one front wheel axis and two rear wheel axes, it is possible to measure the weight at once by placing the front wheel on the A axis and the rear wheel on the C and D axes, for example. For this reason, it is preferable that the distance between the C-axis and the D-axis is equal to the distance between the two rear wheels of the vehicle. In Japan, the distance between the two rear wheel axes is generally between about 1100 and 1450 mm, and it is preferable to arrange the C-axis and D-axis measuring devices 50b so as to cope with this. The B-axis corresponds to a vehicle with three rear wheels, or it can be arranged as a spare for a two-wheel vehicle with a change in the inter-axis distance, for example. The distance between the front wheel A-axis and the rear wheel B-axis and beyond varies greatly depending on the vehicle, and the front-wheel A-axis measuring device 50a is often moved and used according to the vehicle. For this reason, it is desirable that the front wheel measuring device 50a be small and light. Although there are vehicles with two front wheels, a pair of measuring devices 50a for the front wheels may be additionally arranged corresponding to this, or the vehicle is moved as shown and measured for each front wheel by one axis. It is also possible to add the results.

  The operation of the entire vehicle weight measuring apparatus 100 is as follows. An electric signal related to the weight detected by each measuring instrument 50 is sent to the summing box 102 to calculate the weight of each axis, and this is further input to the processor 103 for the entire vehicle. The weight is calculated and recorded, and the result is sent to the external display 104 to display the weight. Each element is connected with necessary cables.

  In the prior art, only a plurality of measuring instruments 50 may be arranged and used in an appropriate position as described above, but generally, as shown by the shaded portion in FIG. In many cases, a rubber mat 51 having an appropriate thickness is laid between the B-axis and the D-axis for the rear wheel. Even though the measuring device 50 is flat, it has a thickness of 5 to 8 mm. When the vehicle rides on the measuring device 50, vibrations and impacts are generated. This mainly causes two problems. One is that, particularly when measuring the weight of a running vehicle, an impact load is likely to be applied to the measuring instrument due to the repulsion of vibration caused by the wheel climbing, and the measurement accuracy is deteriorated. The other one is that the measuring device 50 is likely to jump up due to vibrations when the wheel rides up, and the measuring device 50 is shifted from a predetermined position by this repetition.

  For this reason, the rubber mat 51 is disposed adjacent to the measuring instrument 50 to reduce or eliminate the step in the thickness direction of the measuring instrument 50 to prevent the measurement accuracy problem and the displacement movement problem of the apparatus. In the prior art, the rubber mat 51 is conveyed in a rolled state, and is used by being laid out on the measuring device 50 when used. In the A-axis for the front wheels, the measuring instrument 50a is often moved according to the distance between the axles, so that such a rubber mat 51 is generally not used. In the prior art, in order to further avoid the influence on the measurement accuracy due to the impact, instead of the simple rubber plate 51 having a constant thickness, the rubber mat disposed at the position of getting on and off is made into a slope shape, or The use of a special dummy plate designed to alleviate the impact using a plurality of grooves has also been proposed (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 64-21326 Japanese Patent Publication No. 50-19057 Japanese Utility Model Application No. 3-106429

  However, there has been a problem with the above-described vibration mitigation measures by riding a wheel on the measuring device 50 used in the prior art. As shown in FIG. 4, even if the rubber mat 51 is disposed in close contact with the measuring device 50, the rubber mat 51 and the measuring device 50 are disposed independently, so that both are separated while the measurement is repeated. In addition to moving and creating a step, which causes vibrations and affects measurement accuracy, this further facilitates the separation of the two. For this reason, it is necessary to re-lay the rubber mat 51 and the measuring device 50 as necessary at regular intervals, and the measurement during that time is temporarily suspended. Even when the above-described dummy plate is used, there are similar problems, and it is necessary to prepare a dummy plate having a special structure.

  In view of the above problems, the present invention eliminates the vibration problem caused by the separation between the measuring instrument 50 and the rubber mat 51, and the measuring instrument 50 moves away from a predetermined position even when measurement is continued for a long time. It is an object of the present invention to provide a fixture that can be maintained and fixed on a road surface and a vehicle weight measuring device including the fixture.

  The present invention relates to a slope part that can avoid vibrations at the time of getting on and off of a wheel as much as possible, a fixing tool configured to tightly fix a measuring instrument by connecting between a pair of slope parts of getting on and off, and a plurality of the fixing tools are connected. By using a connecting tool, a plurality of fixing tools can be constrained at the same time to solve the above-mentioned problem. Specifically, the following contents are included.

  One aspect according to the present invention is a fixture that at least partially comprises an elastic material for fixing a measuring instrument that measures the weight applied to the wheel of a vehicle that has been ridden so as not to deviate from a predetermined position on the road surface. A measuring instrument formed by a flat main surface having a shape, a pair of rising and falling slope portions arranged along the vehicle traveling direction on the opposite side of the main plane, and a concave step between the pair of slope portions. The measuring surface of the measuring instrument fitted in the fixed portion and the tops of the pair of slope portions are substantially flush with each other, with the main plane being arranged so as to contact the road surface. It is related with the fixing tool comprised so that the said pair of slope part might pinch | interpose the said measuring device from the advancing direction both sides.

  The fixing device may further include a connecting device having a substantially triangular cross section including a flat main surface and a pair of inclined surfaces formed on the opposite side of the main surface as independent separate elements. In the connection tool, the pair of inclined surfaces are in close contact with the descending slope portion of one of the pair of fixtures arranged in series in the traveling direction and the rising slope portion of the other fixture. In this state, the main surface of the connector is configured to connect the measurement surfaces of the pair of measuring devices fixed to the pair of fixtures in a substantially flush state substantially parallel to the road surface. Can do.

  The fixture may be provided with a gripping hole in each of the pair of slope portions. On the other hand, the connection tool can be provided with protrusions that protrude from the pair of inclined surfaces. Both of them can be configured such that the projection fits into a gripping hole of the fixture when the connector is put over the pair of fixtures. Thereby, a connection tool restrains a pair of fixing tools relatively and makes fixing of a measuring device more reliable.

  The fixing device can be configured such that both the slope portions overlap each other by folding the fixing portion, and the gripping hole can be used for gripping during transportation in this state.

  Another aspect according to the present invention is a vehicle weight measurement in which a vehicle is mounted on a plurality of measuring devices arranged at predetermined positions on a road surface, and the weight of each vehicle wheel is detected and added to measure the weight of the vehicle. The apparatus relates to a vehicle weight measuring apparatus, wherein at least a part of the plurality of measuring devices is fixed to a road surface by the fixture described in any one of the above.

  By using the measuring apparatus fixture of the present invention, the measuring instrument is prevented from shifting and moving even when the vehicle is repeatedly placed in the vehicle weight measuring apparatus, and it is possible to increase the time without trouble. There is an effect that weight measurement that is stable with accuracy can be continued. In addition, by using a coupling tool that couples a plurality of fixing tools and restrains them together, the same effect can be obtained more reliably and over a longer time.

It is the perspective view which shows the fixing tool of the vehicle weight measuring apparatus which concerns on embodiment of this invention, and a reference drawing. It is the perspective view which shows the coupling tool of the vehicle weight measuring apparatus which concerns on other embodiment of this invention, and the reference drawing at the time of use correspondence. It is a top view which shows the whole structure of the vehicle weight measuring apparatus which concerns on other embodiment of this invention. It is a top view which shows the whole structure of the vehicle weight measuring apparatus by a prior art.

  Hereinafter, a vehicle weight measuring device according to a first embodiment of the present invention (hereinafter, also simply referred to as “fixing device”) and a vehicle weight measuring device including the fixing device with reference to the drawings. explain. FIG. 1 shows a fixture 10 according to the present embodiment and a measuring instrument 20 fixed to the fixture 10. In FIG. 1, the fixture 10 forms a concave step between the slope portions 11 (11 a and 11 b) disposed on both the rising side and the descending side in the vehicle traveling direction indicated by the white arrows, and between the slope portions 11. It is comprised from the fixing | fixed part 12. FIG. The fixture 10 is generally made of an elastic material such as rubber, and can be made of natural rubber (NR) or styrene-butadiene rubber (SBR) having a rubber height of 60 to 65 as an example.

  As an example of dimensions, one length of the slope portion 11 (length in the vehicle traveling direction indicated by the white arrow) is 300 mm, the length of the fixing portion 12 (same as above) is 730 mm, and the width of the fixture 10 (vehicle traveling) The width in the direction orthogonal to the direction is uniformly 1700 mm. The slope portion 11 forms an inclined surface having a thickness of about 2 mm at the thinnest portion of both side edges and a thickness of about 14 mm at the thickest portion at the fixed portion 12. A gripping hole 13 is provided near each edge of the slope portion 11, and four 50 mm × 200 mm holes are formed in the illustrated example. The gripping hole 13 is not necessarily a necessary element, and even when it is provided, it is preferable that the gripping hole 13 has a size that does not cause vibrations when the wheel rides on. The thickness of the fixing portion 12 is about 2 mm, and the back surface 14 in which the slope portions 11 and the fixing portion 12 are integrally connected is a flat surface, and the back surface 14 is placed facing the road surface when the measuring apparatus is used. To do.

  A typical example of the measuring instrument 20 is a 1700 mm × 730 mm rectangle having a plane shape that fits the fixing portion 12 and has a thickness of about 5 mm. By fixing the reinforcing plate 16 such as a veneer plate of about 5 mm to this, the measuring device 20 is completely fit in the fixing portion 12 without any step, and the periphery is surrounded by the rubber material of the fixture 10. For this reason, once the measuring instrument 20 is accommodated in the fixing part 12, it is firmly restrained by the rubber surface, and relative movement with the fixing tool 10 is avoided. In order to avoid the occurrence of vibration, it is preferable that the surface of the measuring device 20 and the top of the slope portion 11 are flush with each other. When the entire measuring device is withdrawn, the restraint of the measuring device 20 is easily released by lightly lifting the main plane 14 side of the back surface of the flexible fixing portion 12, and the measuring device 20 can be separated. After that, as shown in the lower figure, the fixture 10 itself is folded at the thin portion of the fixing portion 12 and the palm is inserted into the portion where the gripping holes 13 in both slope portions 11 overlap to form a bag shape. It can be carried and transported. Although not shown, if the dimensions are appropriately selected, the measuring device 20 may be sandwiched between the folded fixtures 10 and conveyed simultaneously.

  By using a unit in which the fixture 10 and the measuring device 20 are combined in this way (hereinafter, this combination is also referred to as “measuring unit 30” for convenience), the measuring device 20 is a rubber sheet ( In addition to being able to move away from FIG. 4 and the reference numeral 51), stable measurement is possible, and the presence of the slope portion 11 can alleviate vibrations when the wheel rides up and improve measurement accuracy. . Further, it is not necessary to separately arrange other vibration damping mechanisms such as a dummy plate. Since the main plane 14 of the fixture 10 made of an elastic material such as rubber is in close contact with the road surface, the fixing effect is remarkably improved as compared with the prior art. Furthermore, the main plane 14 is not a smooth surface, but is subjected to a surface treatment for increasing frictional resistance, such as a rough surface or a surface including irregularities, or a material having a high friction coefficient is applied to the main plane 14. The effect of fixing to the road surface can be further enhanced by application or pasting. Also during transportation, the fixture 10 is folded and can be easily moved by holding it, making it much easier than carrying a roll-shaped rubber sheet tied up as in the past, and the burden of installation and removal. Is greatly reduced. The plurality of fixtures 10 can be stacked and transported in a folded state.

  In the above description, the slope portion 11 has the same structure on the boarding side and the boarding / exiting side. However, a difference may be provided between the slopes of the slope portions 11. For example, a long (small slope) slope portion may be used on the ride side to make the travel as smooth as possible, and a short (large slope) slope portion may be provided on the exit side. Moreover, although the top part of the slope part 11 is directly the edge of the level | step difference of the fixing | fixed part 12, it may be comprised so that the level | step difference of the fixing | fixed part 11 may be provided following a flat part further providing a flat part near the top part. .

  Further, in the above example, the fixture 10 is premised on the integral molding of the elastic material. For example, the main plane 41 including the bottom surface of the fixing portion 12 is a rectangular thin plate elastic material, and a pair of slopes such as a wooden slope, for example. The part 11 may be provided as a separate body and attached to the thin plate. In this case, it is preferable to attach an elastic material such as rubber to the stepped surface facing the fixing portion 12 side of the slope portion 11 in order to securely fix the measuring instrument 20. That is, at least a part of the fixture 10 may be formed of an elastic material.

  Next, a fixture for a vehicle weight measurement device according to a second embodiment of the present invention and a vehicle weight measurement device including the fixture will be described with reference to the drawings. The fixture according to the present embodiment further includes another element separated from the fixture 10 described in the first embodiment, and the two fixtures 10 are arranged in series in the vehicle traveling direction. Used to connect the two. In order to distinguish it from the fixture 10 of the previous embodiment, it will be referred to herein as a “connector 40”. However, the connector 40 cannot perform a fixing function by itself, and Used with fixture 10 as one element.

  The outline of the connector 40 is shown in the upper part of FIG. The connection tool 40 according to the present embodiment has a substantially triangular cross section in which the chevron is turned upside down. The mountain-shaped cross section of the connector 40 is composed of a pair of inclined surfaces 41 (41a, 41b) facing downward and a main surface 42 (appearing behind the drawing) on the opposite side. The pair of inclined surfaces 41 have a width and an inclination angle aligned with the slope portions 11 (11b, 11a) of the two fixtures 10 shown in FIG. The slope portion 11 is configured to be in close contact with each other by covering the two measuring instrument units 30 (30a, 30b) from above with the connecting tool 40 as indicated by a broken line arrow.

  A plurality of protrusions 43 protrude downward from each inclined surface 41, and the protrusions 43 of the coupling tool 40 are respectively aligned with the gripping holes 13 provided in the slope portions 11 of the two fixing tools 10. It is formed by position and size. Thereby, when the connector 40 covers the two measuring instrument units 30 a and 30 b, the projections 43 are configured to fit into the gripping holes 13 of both measuring instrument units 30.

  The lower side of FIG. 2 shows the situation at that time, and the two measuring instrument units 30a and 30b each having the measuring instrument 20 restrained by the fixture 10 are along the vehicle traveling direction indicated by the white arrow. The connector 40 is placed from above at a position where they are arranged in series and contact each other. At this time, each inclined surface 41 of the coupling tool 40 is perfectly overlapped with the adjacent descending slope portion 11 b and the rising slope portion 11 a of the pair of fixing tools 10, and at the same time, each projection 43 of the coupling tool 40 is held in the gripping holes 13 of both slope portions 11. The two measuring instrument units 30a and 30b are connected to each other and restrained. Thereby, a pair of measuring device 20 is restrained more firmly including the relative positional relationship of both, and improves a fixing effect. Further, the main surface 42 of the connector 40 is a flat surface that is substantially parallel to the road surface between the two measuring devices 20 and connects the two measuring devices 20 in a substantially flush state. Vibration due to getting on and off the wheels of the vehicle is avoided, and more stable measurement work can be realized. In the illustrated example, two measuring instrument units 30a and 30b are arranged in the traveling direction. However, another measuring instrument unit 30 is arranged in series, and another connecting tool 40 is used at that time. The added measuring instrument unit 30 can also be constrained continuously. If necessary, further connections are possible.

  In addition, the connection tool 40 connects the pair of measuring instruments 20 in a substantially flush state, thereby providing a further advantage of avoiding measurement errors resulting from height differences. Generally, in the case of a vehicle with two rear wheels, the trunnion shaft is used to make the load between the two shafts equal even if one of the wheels rides on an obstacle. It is inevitable that the weight of the shaft increases. In the configuration shown in FIG. 2, it is good if the two rear wheels are just on the measuring device 20 and the weight can be measured simultaneously. However, when the vehicle is moved and measured one by one, one of the axes is measured. On the vessel 20, the other axis may be on the road surface and a step may be formed between the two axes. In such a case, there is a problem that both the two axes to be measured are measured with a greater weight, and are added to increase the measured value from the actual vehicle weight. Particularly in overloading control, a vehicle that does not violate this may be determined as a violating vehicle, which may cause a conflict. For this reason, the vehicle weight measuring device for the control is specifically required to have an error range of 0 to -5%. By adopting the connector 40 according to the present embodiment, the two axes are kept at the same height even when the two axes are not on the measuring device 20 at the same time, thereby avoiding problems that may arise due to such measurement errors. Will be able to.

  Various modifications can be made to the connector 40 described above. First, the two inclined surfaces 41 may not have a symmetrical shape, but may have a difference in inclination angle and length. However, in this case, it is necessary that the slope of the slope portion 11 of the fixture 10 as the counterpart is also matched. Moreover, a flat part can be provided in the vertex of the mountain shape which became downward, and the length of the advancing direction of the connection tool 40 can be formed long by that much. As a result, the two measuring instrument units 30 can be arranged with a gap between the two measuring unit units 30 without being in close contact with each other, and the separated two units can be connected by the connecting device 40 having the flat portion. . Such a correspondence makes it possible to widen the distance between both measuring instrument units 30 in the traveling direction according to the distance between the axles.

  In addition, the fixing of the connector 40 and the measuring instrument unit 30 is not a method of fitting the protrusion 43 as described above into the gripping hole 13. A convex portion may be provided on the connector 40 and the two may be fitted together. Or you may connect by other methods known by the prior art, such as temporarily joining using a double-sided adhesive tape between both, without providing such a connection part. The material of the connector 40 can be an elastic material such as rubber similar to that of the fixture 10, but other materials that are preferably lightweight, such as plastic materials and wood, may also be used.

  Next, a vehicle weight measuring apparatus according to a third embodiment of the present invention will be described with reference to the drawings. In the present embodiment, the vehicle weight measuring device using the fixture 10 and the connector 40 described in the first and second embodiments is an object, and an outline thereof is shown in the plan view of FIG. . In FIG. 3, a measuring apparatus 1 according to the present embodiment is composed of one axis (A axis) for measuring the front wheel weight and three axes (B, C, D axes) for measuring the rear wheel weight. The measuring instrument unit 30 or measuring instrument 20 is arranged for each of the left and right wheels. In the illustrated example, only the measuring instrument 20 without the fixture 10 is disposed on the A-axis for the front wheel. This is also the case with the prior art shown in FIG. 4, in order to facilitate the movement of the measuring device 20 on the front wheel side in accordance with the change in the distance between the front and rear wheels, and most of the load, particularly in the case of a truck, is rearward. This is because the influence of the measurement error on the front wheel side is small at the time of measuring the weight of the vehicle on the wheel, but the measuring instrument unit 30 provided with the fixture 10 may also be arranged on the front wheel.

  On the rear wheels B to D, the measuring instrument unit 30 as shown in the first embodiment is arranged in a total of six units for both the left and right wheels along the vehicle traveling direction indicated by the white arrows. Has been. Although omitted in FIG. 3, a connecting tool 40 as shown in the second embodiment is put on the pair of measuring instrument units 30 connected in the traveling direction, and both measuring instrument units 30 are connected. And are bound to each other. Also, although omitted in FIG. 3, the movements between the two measuring instrument units 30 in the horizontal direction in the figure in the relationship of being arranged for the left and right wheels on each axis are also constrained to move with each other. A device may be devised. One example is indicated by a broken line on each side surface of the slope portion 11 of the fixture 10 shown in FIG. 1. Here, the concave portion and the convex portion are alternately provided and placed on the road surface on the other side. The fixture 10 is configured to mesh with the convex and concave portions and restrain mutual movement. This is merely an example, and other restraining means known in the prior art may be used.

  An electric signal related to the weight detected by each measuring device 20 is sent to the summing box 2 to calculate the weight of each shaft, which is further input to the processor 3 to calculate and record the weight of the entire vehicle. The result is sent to the external display 4 to display the weight. Each element is connected with necessary cables. The basic configuration of these measuring devices may be the same as that according to the prior art.

  The operation of the vehicle weight measuring apparatus 1 configured as described above is as follows. A vehicle entering in the direction indicated by the white arrow rides on the measuring unit 30 in order from the D axis toward the A axis, and the front wheel rides on the A axis. By the way, the weight of each axis is measured. At this time, for a vehicle having only two front and rear wheels, measurement is performed between any one of the B to D axes and the A axis, and in the case of a total of three axes (two rear wheels), the C and D axes. Alternatively, it is measured between the B, C axis and the A axis, and in the case of 4 axes (rear wheel 3 axes), it is measured using all axes A to D. In this embodiment, the length of the effective measurement surface in the traveling direction of each measuring instrument 20 is increased from 525 mm to 630 mm, and the measurement position is changed for all of the normal inter-axis distances 1100 to 1450 mm in Japan. It is possible to measure without. However, it is possible to calculate the total weight of a vehicle having a distance between other axes or a multi-axis vehicle having more than four axes by moving the measurement apparatus 1 and measuring it multiple times. It is. Further, in the illustrated case, a vehicle pattern consisting of one front wheel axis and three rear wheel axes is shown, but other combinations, for example, the front wheels are set to two axes, and the rear wheels are a single axis or a plurality other than the three axes. The present invention can be similarly applied even to a combination of axes.

  The advantages of using the vehicle weight measuring device 1 according to the present embodiment are the same as the advantages of the fixture 10 described in the first embodiment, that is, the measuring instrument is prevented from being displaced due to vibration or the like. As a result, the measurement accuracy is improved, and the labor during installation before and after the installation and removal of the apparatus and before and after the measurement work is greatly reduced.

  The fixing device (including the connecting device) according to the present invention, and the vehicle weight device using the fixing device are the vehicle weight management at the time of loading and unloading, measures for preventing overloading, public road overload control by the government, etc. It can be used in various industrial fields.
