Description

  The present invention relates to a container loading platform used when a frame part, which is a railway vehicle part, is stored in a container.

  In recent years, railcar manufacturing processes have been adopted in which railcar parts, which are the main parts of railcars, are manufactured in Japan, transported to overseas local factories, and then completed at the local factories. . When transporting the underframe parts overseas by ship or the like, for example, a method in which the underframe parts are stacked on a transport ship and transported by a bulk carrier or the like is employed.

JP 2007-308169 A

  When transporting the frame parts overseas, if the frame parts can be placed on a gantry and stored in a container, the frame parts can be transported from the production factory to the port, and the port or ship before departure. The frame parts can be transported at low cost and high efficiency in the storage of the frame parts in the country, the handling work of loading and unloading from the ship, and the domestic transportation in the exporting country.

  However, underframe parts are large railway vehicle parts, and it is generally difficult to store them in containers. Furthermore, in some cases, there are restrictions such as requiring a dedicated packing material to cover the underframe parts and a special storage place for the underframe parts, so there is room for improvement in terms of transportation costs. Exists.

  The present invention has been made in view of the above-mentioned problems, and by storing railway vehicle parts such as underframe parts in a container well and transporting the railway vehicle parts together with the container, the present invention is lower in cost. It is another object of the present invention to provide a container loading platform capable of transporting railway vehicle parts with high efficiency.

  One aspect of the present invention is a container loading platform that is accommodated in a container in a state in which a frame component of a railway vehicle having at least one of a pillow beam or an end beam is loaded, and includes a horizontally disposed upper surface and A frame having a lower surface, and a pallet frame on which the frame frame components are stacked so that the longitudinal direction of the vehicle is along the upper surface; and a pedestal frame that is erected on the pallet frame and tilts the frame components with respect to a horizontal direction And an oblique receiving member that supports the underframe component from the lower surface side, and when the underframe component is loaded, the oblique receiving member supports at least one of the pillow beam or the end beam. Is arranged.

  The container stacking base of one aspect of the present invention having the above-described configuration has an oblique receiving member disposed on the upper surface of the pallet frame so as to incline and support the base frame components from the lower surface side. For this reason, the horizontal transport width of the frame parts can be reduced as compared with the case where the frame parts are stacked on the pallet frame. Therefore, the width of the container loading platform is made smaller than the width of the container, and the total height of the frame components and the container loading platform is set lower than the height of the container. It can be stored in a container.

  In addition, by placing the oblique receiving member so as to support at least one of the pillow beam or the end beam of the underframe part, the load of the underframe part is concentrated, and the part of the underframe part having relatively high strength Can be supported by the oblique receiving member from its lower surface. Thus, the frame parts can be loaded on the container loading platform with high stability, and the frame parts can be transported satisfactorily.

  According to the above aspect of the present invention, railcar parts such as underframe parts are stored in a container well and can be transported together with the container, thereby transporting railcar parts at a lower cost and higher efficiency than before. It is possible to provide a container loading platform that can be used.

As an example, the size of the gantry 1 is set to a size (total length 5850 mm × total width 2320 mm × maximum height 2450 mm) that can be accommodated in a 40-foot type ISO container.

  The pallet frame 2 is a basic part of the gantry 1 and is a frame body having an upper surface and a lower surface arranged horizontally. The outer shape of the pallet frame 2 has a rectangular shape (as an example, a substantially rectangular shape) when viewed from above. The pallet frame 2 is configured by connecting a plurality of long beams 2a arranged in parallel to each other and a plurality of short beams 2b arranged in parallel perpendicularly to the respective longitudinal directions of the long beams 2a in a lattice shape. The As shown in FIG. 2, the pallet frame 2 has a plurality of bolt fastening portions 2C on one end side in the width direction and a plurality of bolt fastening portions 2D on the other end side in the width direction on the upper surface thereof. In the gantry 1, railway vehicle parts (specifically, frame parts) are loaded so that the longitudinal direction of the pallet frame 2 and the longitudinal direction of the vehicle are parallel to each other.

  The pallet frame 2 has a rectangular shape in plan view, and has a tapered portion R in which the width between any one of the pair of end sides gradually decreases toward both ends of the pair of end sides. Specifically, in the pallet frame 2, all four corners of the outer periphery are chamfered, and four tapered portions R whose width gradually decreases toward both ends of a pair of end sides along the longitudinal direction of the pallet frame 2 are formed. Yes. Due to the presence of the tapered portion R, the gantry 1 is easy to be drawn into the central portion of the container when stored in the container, and is designed to be easily loaded into the container.

  The oblique receiving member 3 is formed of a long member, specifically, a tubular body having a square cross section. Each of the oblique receiving members 3 extends between the pallet frame 2 and the support member 4 and is spaced in parallel with each other. Here, one of the oblique receiving members 3 overlaps at least one of the pillow beam W1 or the end beam W2 of the frame component W when the frame component W is loaded on the gantry 1 (in this embodiment, the pillow beam). (Overlapping both W1 and end beam W2).

  The inclination angle between the horizontal direction and each oblique receiving member 3 is set to an angle (for example, a range of 30 degrees or more and 60 degrees or less, for example, 45 degrees) that allows the frame part W to be stored in the container most efficiently. Yes. With the above configuration, each oblique receiving member 3 supports the frame part W inclined with respect to the horizontal direction from the lower surface Wf when the frame part W (see FIG. 4) is loaded on the frame 1.

  As shown in FIG. 2 as a specific configuration, the oblique receiving member 3 has bolt fastening portions 3a, 3b, 3c in this order on one end side and a middle portion in the longitudinal direction and on the other end side. The oblique receiving member 3 uses a bolt, and is connected to the bolt fixing part 2C of the pallet frame 2 at the bolt fixing part 3a, and is connected to the bolt fixing part 4b2 of the receiving beam 4b at the bolt fixing part 3b.

  The support member 4 includes a plurality of columnar members 4a erected on the upper surface of the pallet frame 2 at intervals, and a single receiving beam 4b disposed horizontally over each upper portion of the columnar member 4a. The support member 4 supports the diagonal receiving member 3 on the pallet frame 2 with the receiving beam 4b being inclined with respect to the horizontal direction. Further, the support member 4 transmits the weight of the base frame component W loaded on each oblique receiving member 3 to the pallet frame 2 side via the receiving beam 4b and each columnar member 4a.

  As a specific configuration, as shown in FIG. 2, the columnar member 4a has a bolt stop 4a1 on one end side (lower end side) in the longitudinal direction and a bolt stop portion 4a2 on the other end side (upper end side). Each columnar member 4a uses a bolt, and is connected to the bolt stopper 2D of the pallet frame 2 at the bolt stopper 4a1 so as to stand upright on the upper surface of the pallet frame 2.

  Further, the receiving beam 4b has bolt fastening portions 4b1 and 4b2 arranged at intervals. The receiving beam 4b is fixed to each columnar member 4a in a state where the receiving beam 4b is horizontally arranged over the upper portion of each columnar member 4a by being bolted to the bolt stopping portion 4a2 of each columnar member 4a at the bolt retaining portion 4b1. . Further, the receiving beam 4b is fixed to each oblique receiving member 3 by being connected to the bolt retaining part 3b of the oblique receiving member 3 by bolt fastening at the bolt retaining part 4b2.

  The end member 5 is disposed so as to face the first end Wa of the longitudinal end of the frame part W from the longitudinal direction of the vehicle when the frame part W is loaded on the pallet frame 2 (see FIG. 4). ). The end member 5 is composed of a long member, specifically a columnar member, and has a bolt stop 5a on one end side in the longitudinal direction and a bolt stop 5b on the other end side. Further, the end member 5 has a pair of bolt fastening portions 5c disposed on the side surfaces thereof at intervals. The bolt stopper 5c is a plate-like body provided with a plurality of long holes 5c1 through which bolts for connecting the first contact member 5A are passed. The long holes 5 c 1 are arranged in two rows so that the respective longitudinal directions are aligned with the longitudinal direction of the end member 5. The end member 5 uses a bolt, and is connected to the bolt stop 2C of the pallet frame 2 at the bolt stop 5a, and is connected to the bolt stop 4b2 of the receiving beam 4b at the bolt stop 5b. Thereby, the end member 5 is installed over the pallet frame 2 and the support member 4 in a state where the end member 5 is inclined with respect to the horizontal direction at the same inclination angle as the oblique receiving portion 3.

  5 A of 1st contact members are columnar members as an example, and have the plate-shaped volt | bolt stop part 5 A1 distribute | arranged to the end. 5 A of 1st contact members are connected with the bolt stop part 5c in the bolt stop part 5A1 with the volt | bolt which let the long hole 5c1 pass. Thereby, 5 A of 1st contact members project from the side surface of the end member 5 toward the end surface of the 1st end part Wa so that it may contact | abut with the 1st end part Wa. Thus, the first contact member 5 </ b> A contacts the first end portion Wa of the frame part W, thereby aligning the frame part W with respect to the gantry 1. The first contact member 5A supports the frame part W from the first end Wa side.

  The second abutting member 6 is a clamp that uses a push bolt as an example, and is an oblique receiver that is closest to the second end Wd so as to abut on the second end Wd at the other longitudinal end of the frame part W. It is connected to the member 3d using a bolt. The second contact member 6 contacts the end surface of the second end Wd, thereby aligning the frame component with the gantry 1 together with the first contact member 5A. The second contact member 6 supports the frame part W from the second end Wd side.

  The support leg 7 is composed of a long, thick member, specifically a quadrangular columnar member, and is arranged on the lower surface of the pallet frame 2 with the longitudinal direction aligned with the horizontal direction. At this time, the support leg 7 is in contact with the placement surface G of the container or the like on one side surface among the four side surfaces around the column axis, and is in contact with the lower surface of the pallet frame on the other side surface. A plurality of support legs 7 are arranged on the lower surface of the pallet frame 2 at intervals (for example, a total of eight). Thereby, the support leg 7 transmits the total weight of the gantry 1 and the frame part W to the mounting surface G side for installing the gantry 1 (see FIG. 4). Further, the support leg 7 forms a gap between the mounting surface G and the pallet frame 2 and guides the support claw (fork) of the forklift to the gap so that the gantry 1 can be lifted.

  Of the plurality of support legs 7, one or more of the support legs 7 is partially outward from one side in the width direction of the pallet frame 2 (the side located in the vehicle width direction of the base frame component W). Is projected. Thus, a step corresponding to the height of the long beam 2a is formed between the upper surface of the pallet frame 2 and the upper surface of each support leg 7 projecting outward.

  Further, as shown in FIG. 1, the gap D between the two adjacent support legs 7 near the center of gravity gxy of the pallet frame 2 is narrower than the gap between the two adjacent short beams 2b. Since it is set to match greatly, it is possible to lift the gantry 1 by inserting support claws from the side surface of the gantry 1 by a forklift. The interval between the two adjacent support legs 7 can be set in accordance with the purpose of adjusting the maximum width of the support pawls of the forklift, regardless of the interval between the long beams 2a and the short beams 2b constituting the pallet frame 2. The support legs 7 are rounded at the corners of the four side surfaces around the column axis so that the pedestal 1 can be lifted diagonally with a forklift and can be easily moved by sliding the pedestal 1 along the mounting surface G. Has been devised. The support leg 7 to be subjected to such R processing may be at least one, but it is desirable to perform R processing on all the support legs 7.

  As shown in FIG. 2, the extended support member 8 has an inclined surface 8 a having an inclined surface set at the same inclination angle as that of the oblique receiving member 3 on the upper surface, an adjacent to the inclined portion 8 a, and a horizontal surface on the upper surface. And a horizontal portion 8b. The extended support member 8 is arranged on the upper surface of the support leg 7 so that the inclined surface of the inclined portion 8 a is aligned with the upper surface of the oblique receiving member 3, and the horizontal portion 8 b is one side portion in the width direction of the pallet frame 2. It is arranged on the upper surface of each support leg 7 projecting more outward. Accordingly, the extension support member 8 supports the periphery of the end Wb of the base frame component W supported by the oblique receiving member 3 from the lower surface Wf side on the extension line in the longitudinal direction of the oblique receiving member 3.

  As shown in FIG. 2, the lower support member 9 has a support surface 9a inclined with respect to the horizontal direction. In the gantry 1, the lower support member 9 is detachably disposed on the horizontal surface of the horizontal portion 8 b of the extended support portion above the support leg 7 by bolting while the support surface 9 a faces the inclined surface of the inclined portion 8 a. . The lower support member 9 supports the frame part W by coming into contact with an end Wb (see FIG. 4) located below the frame part W when the frame part W is loaded on the gantry 1. Specifically, the lower support member 9 is in surface contact with an end surface (an end surface along the direction intersecting the inclination direction of the oblique receiving member 3) existing at the end Wb of the base frame component W on the support surface 9 a. By abutting, the end portion Wb of the base frame component W is supported obliquely from below.

  The upper fixing member 10 has an L-shaped structure, and is connected using a bolt at a bolt stop portion 3c of the portion of the oblique receiving member 3 positioned above the underframe component W in the inclination direction. As a result, the upper fixing member 10 holds the end Wc located at the upper side in the inclination direction of the frame part W together with the oblique receiving member 3. Even when vibration is applied to the gantry 1, the frame part W is fixed so as not to be separated from the gantry 1 by pressing the end Wc toward the oblique receiving member 3.

  The bottom plate 11 has a pallet so that at least a part (partial space S) of the pallet frame 2 surrounded by the two adjacent long beams 2a and the two adjacent short beams 2b is closed from the lower side of the pallet frame 2. It is fixed to the frame 2. Thereby, when the gantry 1 is disassembled, any part detached from the pallet frame 2 can be stored in the partial space S.

  The guide bumper 12 has a bumper member made of a plurality of long L-shaped plates, and is arranged so as to surround the outer periphery of the pallet frame 2 and each support leg 7. Here, at least the bumper members 12a to 12c extend over the front ends in the projecting direction of the support legs 7 that protrude partially outward from one side in the width direction of the pallet frame 2 as shown in FIG. It arrange | positions and protects the edge part Wb of the frame component W from the outside. The lower support member 9 is detachably attached by bolting. As a result, the guide bumper 12 alleviates the impact caused by the collision of the object with the gantry 1 from the outside. The guide bumper 12 guides the gantry 1 by contacting the inner wall of the container C when the gantry 1 is stored in the container C.

  The upper spacer 13 is a columnar member, and is erected on both ends in the longitudinal direction of the pair of short beams 2 b located at both ends in the longitudinal direction of the pallet frame 2. When the plurality of pallet frames 2 are stacked (see FIG. 11), the upper spacer 13 contacts and supports the pallet frame 2 located above when the plurality of pedestals 1 are disassembled. As a result, a certain gap is formed between the upper and lower pallet frames 2, and constituent members generated by disassembling the gantry 1 can be accommodated in the gap.

  The positioning rib 14 is erected in an L shape near the periphery of the upper surface of the upper spacer 13 when the upper surface of the pallet frame 2 is viewed in plan. Thereby, the positioning rib 14 contacts the upper pallet frame 2 and positions the pallet frames 2 when the pallet frames 2 of the disassembled mount 1A are stacked.

  In addition, a buffer member for protecting the frame part W is arranged on the gantry 1 at any contact portion with the frame part W. Specifically, the buffer member P is arranged on a part or more of the surface of the oblique receiving member 3 with which the frame part W comes into contact. The buffer member P has a plate shape and is configured using a resin material (for example, nylon 6) having an appropriate hardness. The same buffer member is also arranged on each surface of the extended support member 8, the lower support member 9, and the upper fixing member 10.

  In addition, as shown in FIG. 2, in the gantry 1, at least the pallet frame 2, the oblique receiving member 3, the support member 4, the end member 5, the first contact member 5A, the lower support member 9, and the upper fixing The member 10, the bumper members 12a to 12c, and the second contact member 6 (hereinafter, these constituent elements are referred to as “constituent member group A”) are detachably fastened by a fastening structure using bolts. Yes. Accordingly, by removing the bolts of the respective fastening structures, any of the constituent member groups A can be detached individually.

  When there are a plurality of pallet frames 2 from which the component group A is removed, the pallet frames 2 can be stacked on each other by placing the upper pallet frame 2 on the upper spacer 13 of the lower pallet frame 2.

  Hereinafter, based on the step diagram of FIG. 3, the transportation of the frame part W using the gantry 1 is illustrated using FIGS. 4 to 11. FIG. 4 is a sectional view taken along the line IV-IV in FIG.

  First, before performing step S1, the lower support member 9, the upper fixing member 10, the bumper members 12a to 12c, and the pair of second contact members 6 are removed from the pallet frame 2 side.

  In step S1, the frame part W is loaded on the gantry 1 according to the following procedure.

  As a first stage, the frame component W is suspended from the upper surface of the pallet frame 2 by a wire and a crane so that the longitudinal direction of the frame component W is aligned with the extended support member 9. Further, the pair of first contact members 5A is removed from each bolt stop portion 5c. 4 and 5, the frame part W is placed on the horizontal portion 8b so that the end surface of the end portion Wb is brought into surface contact with the horizontal surface of the horizontal portion 8b of the extension support member 8 from the vertical direction. .

  Thereafter, the frame part W is inclined as a second stage, and the lower surface Wf of the frame part W is supported by the side surface of the oblique receiving member 3b and the inclined surface of the inclined portion 8a of the extended support member 8. Thereby, the lower surface Wf of the frame part W is inclined with respect to the horizontal direction. Further, the pair of first abutting members 5A are moved along the longitudinal direction of the long hole 5c1 of each bolt stop 5c, and a pair of first abutting members 1 are attached to the first end portion Wa of the base frame component W as shown in FIG. Each end of the contact member 5A is brought into contact. In this state, a bolt is passed through one of the long holes 5c1 of each bolt stopper 5c, and the pair of first contact members 5A are connected to each bolt stopper 5c using the bolt.

  Thus, by carrying out step S1 by dividing into two steps of work, the frame part W can be supported by the oblique receiving member 3 and the extension support member 8 at a predetermined position relatively easily and appropriately. Further, since there is a step between the upper surface of the long beam 2a in the pallet frame 2 and the support leg 7 on which the extended support member 8 is disposed on the upper surface, the end Wb of the base frame component W is connected to the upper surface of the pallet frame 2. Therefore, the total height of the frame part W and the gantry 1 can be reduced to that extent.

  In step S2, as shown in FIGS. 2, 5, and 6, the slope 9a of the lower support member 9 is brought into surface contact with the end surface of the end portion Wb so that the lower support member 9 is extended above the support leg 7. 8 is fixed to the horizontal portion 8b. As a result, the end Wb of the base frame component W is supported by the lower support member 9. Further, bumper members 12 a to 12 c are attached to the support leg 7.

  In step S <b> 3, the upper fixing member 10 is fixed to the upper end portion 3 c of the oblique receiving member 3 as shown in FIGS. 2 and 7. At this time, the upper fixing member 10 is brought into contact with the end Wc of the frame part W, and the end Wc is fixed between the upper fixing member 10 and the oblique receiving member 3.

  In step S4, as shown in FIG. 1, FIG. 2, and FIG. 4, the diagonal receiving member 3 is subjected to the second contact so that the pair of second abutting members 6 abut on the second end Wd of the frame part W. The contact member 6 is attached. Thus, the frame component W is aligned with the gantry 1 together with the first contact member 5A. Further, the frame component W is supported by the second contact member 6 from the second end Wd side.

  Thus, the loading of the frame part W on the gantry 1 is completed.

  Here, since the oblique receiving members 3b and 3c are arranged at positions where they overlap the end beams W1 and pillow beams W2 of the frame part W, the part where the load of the frame part W is particularly concentrated is the lower surface of the frame part W. It can be supported by the oblique receiving member 3 from Wf. Further, in the underframe component W, the peripheral portions of the end beam W1 and the pillow beam W2 are relatively high strength portions. By supporting these portions with the oblique receiving member 3, the bending of the underframe component W can be reduced. Generation of deformation and the like can be prevented. Thereby, the frame part W can be supported on the gantry 1 with high stability, and the frame part W can be transported satisfactorily.

  In step S5, the gantry 1 loaded with the frame parts W is stored in a container. In FIG. 1, forklift support claws (not shown) are inserted into the gap D, and the gantry 1 is lifted. At this time, the gap D between the two adjacent support legs 7 is set according to the maximum width of the support claw, and the center of gravity gxy of the gantry 1 exists between the gaps D. The loaded gantry 1 can be lifted stably by a forklift.

  When the gantry 1 is stored in the container C, the opening at one end in the longitudinal direction of the container C is opened. And the base 1 is accommodated in the container C from the longitudinal direction edge part using the forklift through an opening part.

  Here, the gantry 1 uses the oblique receiving member 3 and the support member 4 to reduce the horizontal transport width of the frame part W compared to the case where the frame part W is stacked on the pallet frame 2. Can do. Accordingly, the width of the gantry 1 is made smaller than the width of the container C, and the total height of the frame part W and the gantry 1 is set to be lower than the height of the container C in advance. As shown, the frame part W can be stored in the container C together with the gantry 1. Here, when a 40-foot container is used as the container C, it is possible to store two racks 1 loaded with the frame parts W as shown in FIG.

  Since the pallet frame 2 has the tapered portion R, when the gantry 1 is stored in the container C, the pallet frame 2 is easily guided into the container C. Further, the gantry 1 is guided when the guide bumper 12 disposed around the gantry 1 touches the inner wall of the container C. Therefore, as shown in FIGS. 8 and 9, the gantry 1 on which the frame part W is mounted can be satisfactorily stored in the container C.

  In addition, since the corner portion of the side surface of the support leg 7 is chamfered (R-processed) in the gantry 1, one end side of the gantry 1 is lifted obliquely with the support claws of the forklift, and the other end side is placed on the mounting surface G. The mount 1 can be stored in the container C by sliding easily.

  Furthermore, if the frame part W is stored in the container C, the frame part W can be managed and transported together with the container C, and the transportation cost of the frame part W can be reduced in Japan and overseas. In addition, since it is relatively easy to store and manage the frame parts W at the port before shipping, if the container C is used, it is relatively easy to store and manage the frame parts W in a flat stack with a special packing. In comparison with this, the storage cost can be reduced.

  Further, when carrying out shipping, the operation of fixing lashing the container C can be performed relatively easily as compared with the case of fixing the flat-stacked base frame part W. Therefore, improvement in work efficiency during shipping can be expected.

  After the completion of step S5, the container C is loaded on the transport ship as step S6, and the forward transportation is performed. Here, since the frame part W is stored in the container C and can be transported, the frame part W can be transported using a container ship having a high speed and a large number of flights instead of bulk carriers for overseas transportation. Can be transported. Therefore, it is possible to transport the frame part W more efficiently than in the conventional case where the frame part W is transported in a flat state to a bulk carrier or the like.

  In step S7, the container C is unloaded from the transport ship. The container C is transported to the local factory, and the platform 1 loaded with the frame parts W is taken out from the container C at the local factory. Then, the frame part W is unloaded from the gantry 1 using a crane.

  In step S <b> 8, the gantry 1 is disassembled and the component member group A is stored in the gap of the pallet frame 2. As shown in FIG. 2, each bolt fastened on the gantry 1 is removed, and the constituent member group A is detached from the pallet frame 2. Here, FIG. 10 shows a state of the disassembled gantry 1A in which the component member group A detached from the pallet frame 2 is housed in the gap of the pallet frame 2 and the component member group A is connected to the pallet frame 2 with bolts. . In the disassembled gantry 1 </ b> A, the second contact member 6 is removed from the oblique receiving member 3 and then placed on the bottom plate 11. In FIG. 10, long support members M1 to M11 are connected to the inside of the pallet frame 2, and the constituent member group A can be placed on the support members M1 to M11 along the upper surface of the pallet frame 2. It is devised as follows.

  In step S9, as shown in FIG. 11, the upper spacer 13 of the lower pallet frame 2 is overlapped so as to support the lower surface of the upper pallet frame 2. At this time, the positioning ribs 14 are brought into contact with the upper pallet frame 2, and the upper and lower pallet frames 2 are positioned and stacked. At this time, a gap is secured between the upper and lower pallet frames 2 due to the presence of the upper spacer 13, so that the constituent member group A can be accommodated in the gap. Thereby, each pallet frame 2 of the disassembled gantry 1A can be favorably stacked while avoiding mutual interference. In this state, the plurality of stacked disassembled platforms 1A are stored in the container C using a forklift.

  In step S10, the container C is used to transport the disassembled platform 1A in the return direction. Since the number of containers C used during the return transportation is smaller than that during the outward transportation, the transportation cost can be reduced.

  Although the container C is an ISO standard 40-foot tall type, the container size is naturally not limited to this, and may be other sizes.

  The range of the inclination angle of the oblique receiving member 3 and the end member 5 with respect to the horizontal direction is 30 degrees or more and 60 degrees or less and 45 degrees as an example, but naturally, other inclination angles may be set. However, when the inner width and the indoor height of the container C are substantially equal, the angle of inclination of the oblique receiving member 3 and the end member 5 with respect to the horizontal direction is set to 45 degrees, so that the container frame can be most efficiently attached to the container C. The component W and the gantry 1 can be stored.

  The present invention is not limited to the above-described embodiment, and the configuration can be changed, added, or deleted without departing from the spirit of the present invention.

  When the disassembled gantry 1A is transported in the return path, the use of the support members M1 to M11 is not essential and can be omitted.

  The material of the buffer member is not limited to nylon 6, and other materials such as hard rubber or wood board may be used.

  The size of the gantry 1 can be appropriately adjusted. However, if the size of the gantry 1 is close to the inner size of the container in which the gantry 1 is stored, the space efficiency is improved and unnecessary movement of the gantry 1 inside the container is prevented, and the gantry 1 can be transported stably. Therefore it is desirable. Specifically, it is preferable that the difference between the inner width of the container and the entire width of the pallet frame 2 is within several centimeters.

  As described above, the present invention has an excellent effect that can provide a container loading platform that can satisfactorily store railcar parts for railcars in a container. Therefore, it has a utility that can be widely applied as a container loading platform that can demonstrate the significance of this effect.
