Mode for Carrying Out the Invention

[0014] 〔Embodiment 1〕 Hereinafter, the erecting device 1 according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 7.

[0015] [Erecting Device] FIG. 1 is a side view of the erecting device 1 of Embodiment 1. FIG. 2 is a front view of the erecting device 1 of Embodiment 1. For the sake of convenience of explanation, as shown by the arrows in FIGS. 1 and 2, the vertical direction, the front-rear direction, and the left-right direction of the erecting device 1 are defined.

[0016] As shown in Figures 1 and 2, the erection device 1 is a device for erecting a stacker crane 100 when its mast 20 is lying on its side. The erection device 1 comprises a pair of first support columns 2, a first chain block 3 which is an example of a first hoisting section, a second chain block 4 which is an example of a second hoisting section, a connecting section 5, a lifting section 6, and a support section 7. The total height dimension L1 of the erection device 1 is shorter than the total height dimension L2 of the stacker crane 100 (see Figure 4).

[0017] The pair of first support columns 2 are made of, for example, metal square timbers with a rectangular cross-section. Each first support column 2 extends perpendicularly to the floor surface 200, i.e., vertically. Each first support column 2 has a main body portion 21, an extension portion 22, a base frame 23, a pair of first reinforcing members 24, a second reinforcing member 25, and a plurality of wheels 26.

[0018] The main body 21 extends from the base frame 23 perpendicular to the floor surface 200, i.e., vertically. The extension 22 extends horizontally from the main body 21 toward the front. The front side of the main body 21 corresponds to the top side of the stacker crane 100 when it is lying on its side (see Figure 3).

[0019] As shown in Figure 1, the base frame 23 is provided below the main body 21, extending in the front-rear direction. A pair of first reinforcing members 24 are positioned between the main body 21 and the base frame 23. The pair of first reinforcing members 24 are members for reinforcing the main body 21.

[0020] Furthermore, a second reinforcing member 25 is positioned between the main body 21 and the front end of the extension 22. The second reinforcing member 25 is a member for reinforcing the extension 22. In addition, multiple wheels 26 are provided on the lower part of the base frame 23.

[0021] A first chain block 3 is provided at the top of each of the pair of first support columns 2. Specifically, a first chain block 3 is positioned at the front end of each extension 22. Each first chain block 3 has a chain 31. A hook 32 is provided at the end of each chain 31. Each hook 32 is connected to shackles 61 provided at both ends of the lifting section 6 (see Figure 3).

[0022] Here, Figure 3 is a side view showing the start of erecting the stacker crane 100 by the erection device 1. As shown in Figure 3, a lifting section 6 is attached to the end of each chain 31 of each first chain block 3. Each chain 31 of each first chain block 3 lifts the mast 20 via the lifting section 6, i.e., the central part in the longitudinal direction, i.e., the front-to-back direction. Note that the placement of the lifting section 6 can be changed as appropriate.

[0023] A second chain block 4 is positioned at the rear end of each extension 22. Each second chain block 4 has a chain 41. Each chain 41 of each chain block 4 pulls the bottom of the stacker crane 100.

[0024] As shown in Figure 2, the connecting portion 5 is a member for connecting a pair of first support columns 2. The connecting portion 5 has a first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 connects the upper ends of each main body portion 21. The second connecting portion 52 connects the central portions of each main body portion 21. The first connecting portion 51 and the second connecting portion 52 serve to reinforce the pair of support columns 2. When erecting the stacker crane 100 using the erection device 1, the second connecting portion 52 is to be removed from the pair of support columns 2.

[0025] The lifting section 6 is a horizontally elongated plate-like member extending in the left-right direction. The lifting section 6 is positioned on the underside of one side of the mast 20 of the stacker crane 100 when it is lying on its side. Specifically, the lifting section 6 is positioned on the underside of the mast 20 near the center in the longitudinal direction. Both ends of the lifting section 6 are connected to each chain 31 of each first chain block 3. The lifting section 6 may also be made of a metal pipe or the like.

[0026] The stacker crane 100 is transported to the location where the erection device 1 is positioned, supported by the support section 7. The support section 7 supports the stacker crane 100 on one side and the bottom surface that is on the underside of the stacker crane 100 when the mast 20 is lying on its side. The support section 7 has a plurality of wheels W that come into contact with the floor surface 200 when the stacker crane 100 is erected.

[0027] The erection device 1 is configured such that the support section 7 rotates together with the stacker crane 100 when the lifting section 6 is lifted by each first chain block 3, thereby erecting the stacker crane 100.

[0028] [Stacker Crane] Next, the stacker crane 100, which is erected by the erection device 1, will be described with reference to Figure 4. Figure 4 is a perspective view of the stacker crane 100 of Embodiment 1. For the sake of explanation, the vertical and horizontal directions of the stacker crane 100 are defined as shown by the arrows in Figure 4.

[0029] As shown in Figure 4, the stacker crane 100 comprises four masts 20, an upper frame 30, a lifting body 40, a trolley section 50, a crane control unit (not shown), a lifting motor M1, and a travel motor M2.

[0030] The four masts 20 are mounted extending vertically, i.e., upward from the trolley section 50. Each mast 20 is formed from a vertically elongated hollow member. The upper frame 30 connects the upper ends of each mast 20. The lifting body 40 is supported by each mast 20 and moves along the masts 20.

[0031] The lifting body 40 is configured to grip an object. The lifting body 40 moves up and down along the mast 20 by winding or unwinding the chain C driven by the lifting motor M1. A belt may be used instead of the chain C.

[0032] The bogie section 50 travels along the running rail R. The bogie section 50 supports the running wheels W1 and W2 that roll on the running rail R. Running wheel W1 is provided at the left end of the bogie section 50 and is driven by the running motor M2. Running wheel W2 is provided at the right end of the bogie section 50 so as to be able to rotate freely.

[0033] The crane control unit controls the lifting motion of the lifting body 40 by driving the lifting motor M1. The crane control unit also controls the traveling motion of the trolley 50 by driving the traveling motor M2.

[0034] [Construction Method] Next, the method for erecting the stacker crane 100 using the erection device 1 will be explained with reference to Figures 5 to 7. Figure 5 is a flowchart showing an example of the flow of the method for erecting the stacker crane 100 using the erection device 1.

[0035] As shown in Figure 5, the method for erecting the stacker crane 100 using the erection device 1 involves the following steps in order: placement (S1), lifting (S2), and adjustment (S3).

[0036] In the placement process S1, the stacker crane 100, which is lying on its side, is first transported by workers to the automated warehouse or the like where the erection device 1 is installed, with the crane resting on the support section 7. Then, the stacker crane 100, which is lying on its side, is positioned between the main body sections 21 of the pair of support columns 2 of the erection device 1. Specifically, the central part of the mast 20 in the longitudinal direction is positioned directly below each of the first chain blocks 3.

[0037] Next, the lifting section 6 is positioned on the underside of the stacker crane 100, which is lying on its side, by the workers. Specifically, the lifting section 6 is inserted through several eye bolts (not shown) located near the center of the mast 20 in the longitudinal direction. The lifting section 6 is then positioned on the underside of the mast 20 near the center in the longitudinal direction.

[0038] Next, in the lifting process S2, as shown in Figure 3, the hooks 32 of each chain 31 of each first chain block 3 are connected to the shackles 61 provided at both ends of the lifting section 6. Then, by lifting the lifting section 6 with each first chain block 3, the stacker crane 100 is gradually rotated clockwise in Figure 6, as shown in Figure 6, around the wheel W provided at the front bottom of the support section 7, thereby raising the stacker crane 100. The lifting of the chains 31 is performed manually by the workers. Furthermore, the lifting of the lifting section 6 is performed with the second connecting section 52 detached from the pair of support columns 2.

[0039] Next, in adjustment step S3, the erection device 1 adjusts the rotation of the stacker crane 100 by gradually rotating it clockwise in Figure 6 around the front bottom of the support section 7 by lifting the lifting section 6 with each first chain block 3. Then, as shown in Figure 7, the erection of the stacker crane 100 is completed by adjusting its position to a vertical state.

[0040] In this way, when the stacker crane 100 is raised to a vertical position using the erection device 1, the wheels W provided on the support section 7 come into contact with the floor surface 200, and the wheels W roll on the floor surface 200, allowing the stacker crane 100 to be raised smoothly.

[0041] [Effects of Embodiment 1] In the erection device 1 of Embodiment 1 described above, the stacker crane 100 can be easily erected by lifting the lifting section 6 located on the underside of the stacker crane 100, which is in a lying-down state, using the first chain blocks 3 provided on the upper part of the pair of first support columns 2, thereby rotating the stacker crane 100.

[0042] In particular, since the total height dimension L1 of the erection device 1 is shorter than the total height dimension L2 of the stacker crane 100, the stacker crane 100 can be erected without increasing the height of the erection device 1, and the erection device 1 can be made more compact.

[0043] Furthermore, in conventional methods, when erecting the stacker crane 100 by lifting its top, it was necessary for workers to open the ceiling using an aerial work platform or similar equipment and lift the top of the stacker crane 100 from the steel frame installed behind the ceiling using a chain block or the like. In contrast, with the erection device 1, since the total height dimension L1 of the erection device 1 is shorter than the total height dimension L2 of the stacker crane 100, there is no need to open the ceiling and perform work at height, and the stacker crane 100 can be erected using only ground-level work. In addition, the amount of winding of each chain 31 of each first chain block 3 can be reduced, and the lifting process S2 can be shortened.

[0044] Furthermore, since the pair of first support columns 2 are connected by the first connecting portion 51 and the second connecting portion 52, the durability of the erection device 1 can be improved. Also, since the first chain block 3 is positioned at the front end of the extension portion 22, the first connecting portion 51 can be prevented from interfering with the stacker crane 100 when the stacker crane 100 is erected using the first chain block 3.

[0045] Furthermore, when raising the stacker crane 100 by lifting the lifting section 6 with each first chain block 3, the bottom of the stacker crane 100 can be pulled by each second chain block 4, thereby suppressing the rapid rotation of the stacker crane 100 and allowing the stacker crane 100 to be raised gradually.

[0046] [Embodiment 2] Next, the erection device 1A of Embodiment 2 of the present invention will be described with reference to Figures 8 to 12. For the sake of convenience of explanation, components having the same function as those described in Embodiment 1 will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0047] [Erection device] Figure 8 is a schematic side view showing the start of the erection of the stacker crane 100 by the erection device 1A. Figure 9 is a schematic front view showing the start of the erection of the stacker crane 100 by the erection device 1A. For the sake of explanation, the vertical, horizontal, and lateral directions of the erection device 1A are defined as shown by the arrows in Figures 8 and 9.

[0048] As shown in Figures 8 and 9, the erection device 1A comprises a pair of first support columns 2A, a first chain block 3A which is an example of a first hoisting section, a lifting section 6, a support section 7, a reinforcing section 8, a second chain block 4A which is an example of a second hoisting section, a first connecting section 51A, and a second connecting section 52A (see Figure 11). The total height dimension L1A of the erection device 1A is shorter than the total height dimension L2 of the stacker crane 100 (see Figure 4).

[0049] Each first support column 2A has a front support column 21A, a rear support column 22A, a base frame 23A, and a connecting portion 24A. Each support column 2A extends vertically, i.e., vertically, relative to the floor surface 200. As shown in Figure 9, a pair of support columns 2A are arranged on both sides of the stacker crane 100, spaced apart in the left-right direction.

[0050] The base frame 23A is positioned on the upper surface of the base plate P, which is placed in a recess 201 that is recessed from the floor surface 200. The depth of the recess 201, i.e., its vertical length, is approximately 600 mm. The thickness of the base plate P is approximately 20 mm. Note that the recess 201 is not required; in this case, the base plate P can simply be placed on the floor surface 200.

[0051] As shown in Figure 8, the front support column 21A and the rear support column 22A extend vertically upward from the base frame 23A. The front support column 21A and the rear support column 22A are spaced apart in the front-to-back direction.

[0052] The connecting section 24A connects the front support column 21A and the rear support column 22A. A first chain block 3A is attached to the connecting section 24A. Each first chain block 3A is provided on the upper part of each first support column 2A. Each first chain block 3A has a chain 31A. A hook 32A is provided at the end of each chain 31A. Each hook 32A is connected to a shackle 61 provided at both ends of the lifting section 6.

[0053] Furthermore, a first connecting part 51A is attached to the connection part 24A. As shown in Figure 9, the first connecting part 51A connects the upper parts of a pair of first support columns 2A. The first connecting part 51A is configured to be detachable from the pair of first support columns 2A. The first connecting part 51A is removed during the erection of the stacker crane 100 by the erection device 1A.

[0054] A reinforcing section 8 is positioned on the rear side of each pair of first support columns 2A. Each reinforcing section 8 is connected to each first support column 2A and reinforces each first support column 2A. Each reinforcing section 8 is positioned on the bottom side of the stacker crane 100 when it is lying on its side, relative to each first support column 2A.

[0055] The reinforcing section 8 has a column section 81 and a connecting section 82. The column section 81 extends vertically upward from the base frame 23A. The connecting section 82 connects the rear support column 22A of the first support column 2A to the column section 81.

[0056] Each connection point 82 of each reinforcing section 8 is provided with a second chain block 4A. Each chain 41A of each second chain block 4A pulls the bottom of the stacker crane 100.

[0057] The erection device 1A lifts the lifting section 6 with each first chain block 3A, gradually rotating the stacker crane 100 clockwise in Figure 8 around the front bottom of the support section 7. At this time, the wheels W attached to the support section 7 come into contact with the base plate P, making it easier for the stacker crane 100 to rotate.

[0058] [Construction Method] Next, the method for erecting the stacker crane 100 using the erection device 1A will be explained with reference to Figures 5 and 8 to 12. Figure 10 is a schematic side view showing the stacker crane 100 in the process of being erected by the erection device 1A. Figure 11 is a schematic front view showing the stacker crane 100 in the process of being erected by the erection device 1A. Figure 12 is a schematic side view showing the stacker crane 100 in the state after it has been erected by the erection device 1A.

[0059] In the method for erecting the stacker crane 100 using the erection device 1A of Embodiment 2, first, as in Embodiment 1, the following steps are performed in order, as shown in Figure 5: placement step (S1), lifting step (S2), and adjustment step (S3).

[0060] First, in the placement process S1, the worker places the bottom side of the stacker crane 100, which is lying on its side, on the support part 7 as shown in Figure 8, and drops it onto the upper surface of the base plate P which is placed on the recess 201. At this time, the top side of the stacker crane 100 is left on the floor surface 200.

[0061] Next, the lifting unit 6 is positioned on the underside of the stacker crane 100, which is lying on its side, by the workers. The lifting unit 6 is positioned on the underside of the mast 20, near the center in the longitudinal direction (see Figure 9).

[0062] Next, in the lifting process S2, the stacker crane 100 is gradually rotated by lifting the lifting section 6 with each first chain block 3A. At this time, because there is a step between the floor surface 200 and the upper surface of the recess 201, the stacker crane 100 supported by the support section 7 is easily rotated.

[0063] In Embodiment 2, during the erection of the stacker crane 100, as shown in Figure 10, a second chain block 4A is attached to the front side of the recess 201, and the bottom of the stacker crane 100 is pulled by the chain 41A.

[0064] Furthermore, as shown in Figure 11, the second connecting portion 52A is attached to the pair of first support columns 2A. The second connecting portion 52A connects the central parts of the pair of first support columns 2A in the extension direction. The second connecting portion 52A is configured to be detachable from the pair of first support columns 2A. Note that the second connecting portion 52A cannot be removed from the pair of first support columns 2A when the first connecting portion 51A is removed from the pair of first support columns 2A.

[0065] Then, after attaching the second connecting section 52A to the pair of first support columns 2A, the first connecting section 51A is removed from the pair of first support columns 2A so as not to obstruct the rotation of the stacker crane 100.

[0066] Next, in adjustment step S3, the erection device 1A gradually rotates the stacker crane 100 clockwise in Figure 10 around the wheel W attached to the front bottom of the support section 7 by lifting the lifting section 6 with each first chain block 3A. Then, as shown in Figure 12, the position of the stacker crane 100 is adjusted while lifting the lifting section 6 with each first chain block 3A so that the stacker crane 100 is in a vertical position.

[0067] [Effects of Embodiment 2] In the erection device 1A of Embodiment 2 described above, the same effects as the erection device 1 of Embodiment 1 can be obtained. In particular, since the pair of first support columns 2A are supported by each reinforcing part 8, the durability of the erection device 1A can be improved. Also, when adjusting the posture of the stacker crane 100 to a vertical position, the bottom of the stacker crane 100 is pulled by the chain 41A of the second chain block 4A, so that the sudden rotation of the stacker crane 100 can be suppressed.

[0068] Furthermore, at the start of erecting the stacker crane 100 using the erection device 1A, as shown in Figures 8 and 9, the pair of first support columns 2A are connected by the first connecting portion 51A with the second connecting portion 52A removed from the pair of first support columns 2A. This makes it possible to reinforce the erection device 1A while preventing the second connecting portion 52A from interfering with the rotation of the stacker crane 100.

[0069] On the other hand, as the erection of the stacker crane 100 by the erection device 1A progresses, as shown in Figures 10 and 11, the first connecting portion 51A is removed from the pair of first support columns 2A, and the pair of first support columns 2A are connected by the second connecting portion 52A. This makes it possible to reinforce the erection device 1A while preventing the first connecting portion 51A from interfering with the rotation of the stacker crane 100.

[0070] [Embodiment 3] Next, the erection device 1B of Embodiment 3 of the present invention will be described with reference to Figures 13 to 15. For the sake of convenience of explanation, the same reference numerals will be used for members having the same function as those described in Embodiment 1, and their descriptions will not be repeated. The erection device 1B of Embodiment 3 differs from Embodiment 1 mainly in that it does not have a connecting portion 5 and an extension portion 22 like the erection device 1.

[0071] [Erection device] Figure 13 is a schematic side view showing the start of the erection of the stacker crane 100 by the erection device 1B of Embodiment 3. Figure 14 is a schematic front view showing the start of the erection of the stacker crane 100 by the erection device 1B of Embodiment 3. For the sake of explanation, the vertical, horizontal, and left-right directions of the erection device 1B are defined as shown by the arrows in Figures 13 and 14.

[0072] As shown in Figures 13 and 14, the erection device 1B comprises a pair of first support columns 2B, a first chain block 3B which is an example of a first hoisting section, a second chain block 4B which is an example of a second hoisting section, a lifting section 6, a support section 7, and a second chain block 4B. The total height dimension L1B of the erection device 1B is shorter than the total height dimension L2 (see Figure 4) of the stacker crane 100.

[0073] Each first support column 2B has a front support column 21B, a rear support column 22B, a base frame 23B, and a connecting portion 24B. Each support column 2B extends vertically, i.e., vertically, relative to the floor surface 200. As shown in Figure 14, a pair of support columns 2B are arranged on both sides of the stacker crane 100, spaced apart in the left-right direction.

[0074] The base frame 23B is positioned on the upper surface of the base plate P, which is placed in the recess 201. As shown in Figure 13, the front support column 21A and the rear support column 22A extend vertically upward from the base frame 23B. The front support column 21B and the rear support column 22B are spaced apart in the front-rear direction.

[0075] The connecting section 24B connects the front support column 21B and the rear support column 22B. A first chain block 3B is attached to the connecting section 24B. Each first chain block 3B is provided on the upper part of each first support column 2B. Each first chain block 3B has a chain 31B. A hook 32B is provided at the end of each chain 31B. Each hook 32B is connected to a shackle 61 provided at both ends of the lifting section 6.

[0076] Furthermore, a second chain block 4B is attached to the front side of the recess 201. The second chain block 4B has a chain 41B. The chain 41B of the second chain block 4B pulls the bottom of the stacker crane 100.

[0077] [Construction Method] Next, the method for erecting the stacker crane 100 using the erection device 1B will be explained with reference to Figures 5 and 15. Figure 15 is a schematic side view showing how the stacker crane 100 is erected by the erection device 1B.

[0078] In the method for erecting the stacker crane 100 using the erection device 1B of Embodiment 3, first, the arrangement process S1 shown in Figure 5 is performed, similar to Embodiment 2.

[0079] Next, in the lifting process S2, as shown in the upper diagram of Figure 15, the stacker crane 100 is erected by gradually rotating it clockwise in Figure 15 around the wheel W located at the front bottom of the support section 7, by lifting the lifting section 6 with each first chain block 3B. At this time, the wheel W comes into contact with the base plate P, making it easier for the stacker crane 100 to rotate.

[0080] Next, in adjustment step S3, the erection device 1B adjusts the rotation of the stacker crane 100 by lifting the lifting section 6 with each first chain block 3B, thereby adjusting the posture of the stacker crane 100 to a vertical state, as shown in the lower diagram of Figure 15.

[0081] In this way, when the stacker crane 100 is erected vertically by the erection device 1B, the bottom of the stacker crane 100 is pulled by each chain 41B of each second chain block 4B, thereby suppressing the rapid rotation of the stacker crane 100.

[0082] [Effects of Embodiment 3] In the erection device 1B of Embodiment 3 described above, similar to the erection device 1 of Embodiment 1, the stacker crane 100 can be erected from a lying position without increasing the overall height dimension L1B of the erection device 1B.

[0083] In particular, in the erection device 1B of Embodiment 3, it is not necessary to provide an extended portion 22 on the support column 2B as in the erection device 1 of Embodiment 1, so the length of the erection device 1B in the front-rear direction can be shortened, and the erection device 1B can be made more compact.

[0084] [Embodiment 4] Next, the erection 1C of Embodiment 4 of the present invention will be described with reference to Figure 16. For the sake of convenience of explanation, members having the same function as those described in Embodiment 1 will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0085] [Erection device] Figure 16 is a schematic side view showing how the stacker crane 100 is erected by the erection device 1C. For the sake of explanation, the vertical and horizontal directions of the erection device 1C are defined as shown by the arrows in Figure 16.

[0086] As shown in Figure 16, the erection device 1C comprises a first support column 2C, a second support column 3C, a pair of third chain blocks 4C, a pair of trolleys 5C, a lifting section 6, a support section 7, and a pair of rails 9C. The third chain block 4C is an example of a third hoisting section. The total height dimension L1C of the erection device 1C is shorter than the total height dimension L2 (see Figure 4) of the stacker crane 100.

[0087] The erection operation 1C erects the stacker crane 100 on the upper surface of the base plate P placed in the recess 201. Note that the recess 201 is not required, in which case the erection operation 1C can erect the stacker crane 100 on the floor surface 200.

[0088] The first support column 2C extends perpendicularly to the floor surface 200. The first support column 2C is formed, for example, from a prismatic member. The second support column 3C extends perpendicularly to the floor surface 200. The second support column 3C is formed, for example, from a prismatic member.

[0089] The second support column 3C is positioned opposite the first support column 2C in the front-to-back direction. A stacker crane 100 is positioned between the first support column 2C and the second support column 3C in a lying-down position. Note that the first support column 2C and the second support column 3C may each be a pair of left and right support columns.

[0090] A pair of rails 9C are installed on top of the first and second support columns, respectively. Each rail 9C is spaced apart in the left-right direction. Each rail 9C is formed from an I-beam or H-shaped steel member, etc. Note that in Figure 16, only one rail 9C is shown, and the other rail 9C is omitted.

[0091] A trolley 5C is positioned on each of the pair of rails 9C. Each trolley 5C is positioned to be movable in the front-to-back direction along each rail 9C. Note that in Figure 16, only one trolley 5C is shown, and the other trolley 5C is omitted.

[0092] Each trolley 5C is connected to a third chain block 4C. Each third chain block 4C has a chain 41C. Each third chain block 4C is arranged to be movable in the front-rear direction along each rail 9C. A hook 42C is provided at the end of each chain 41C. Each hook 42C is connected to a shackle 61 provided at both ends of the lifting section 6.

[0093] [Construction Method] Next, the method for erecting the stacker crane 100 using the erection device 1C will be explained with reference to Figures 5 and 16. As shown in Figure 5, the method for erecting the stacker crane 100 using the erection device 1C involves the following steps in order: placement (S1), lifting (S2), and adjustment (S3).

[0094] In the positioning process S1, the lifting unit 6 is positioned below the stacker crane 100, which is lying on its side. At this time, by moving the trolley 5C, it is possible to adjust the lifting position of the lifting unit 6 by the third chain block 4C in the longitudinal direction of the stacker crane 100.

[0095] Next, in the lifting process S2, as shown in the upper diagram of Figure 16, the stacker crane 100 is gradually rotated clockwise in Figure 16 around the front bottom of the support section 7 by lifting the lifting section 6 with each third chain block 4C, thereby raising the stacker crane 100. At this time, the wheels W attached to the support section 7 come into contact with the base plate P, making it easier for the stacker crane 100 to rotate.

[0096] Next, in adjustment step S3, the erection device 1C adjusts the rotation of the stacker crane 100 by lifting the lifting section 6 with each third chain block 4C, thereby adjusting the posture of the stacker crane 100 to a vertical state, as shown in the lower diagram of Figure 16.

[0097] [Effects of Embodiment 4] In the erection device 1C of Embodiment 4 described above, the same effects as the erection device 1 of Embodiment 1 can be obtained. That is, without increasing the overall height dimension L1C of the erection device 1C, the stacker crane 100, which is lying on its side, can be erected by lifting the lifting section 6C with each third chain block 4C.

[0098] In particular, according to the erection device 1C of Embodiment 3, the stacker crane 100 can be erected effectively by adjusting the lifting position by moving the trolley 5C along the rail 9C, thereby adjusting the position of the lifting section 6 in the longitudinal direction of the mast 20.

[0099] [Other Embodiments] In the embodiments 1 to 3 described above, first chain blocks 3, 3A, 3B and second chain blocks 4, 4A, 4B are used as examples of the first and second hoisting sections, respectively, but the invention is not limited to these. For example, wires may be used instead of the chains 31, 31A, 31B of each first chain block 3, 3A, 3B. Similarly, wires may be used instead of the chains 41, 41A, 41B of each second chain block 4, 4A, 4B.

[0100] Although the erection device 1 of Embodiment 1 described above is equipped with a support section 7, it is not limited to this and may not be equipped with a support section 7. In this case, the stacker crane 100 can be erected properly by directly attaching the wheels W to the stacker crane 100. Furthermore, the support section 7 may be composed of a member that supports one side of the stacker crane 100 and a member that supports the bottom surface of the stacker crane 100, which are configured separately.

[0101] Furthermore, in each of the embodiments described above, the stacker crane 100 is provided with four masts 20, but it is not limited to this. The stacker crane 100 may be provided with at least one mast 20, or even just one mast 20.

[0102] Furthermore, in the erection device 1 of Embodiment 1 described above, the lifting of each chain 31 of each first chain block 3 is performed manually by a worker, but this is not limited to this. For example, a control unit may be provided for automatically lifting each chain 31 of each first chain block 3. The control unit may then lift each chain 31 of each first chain block 3, thereby erecting the stacker crane 100 at a constant speed via the lifting unit 6. With this configuration, the stacker crane 100 can be automatically erected at a constant speed by the control unit, thus saving the worker's time and effort.

[0103] In the erection device 1C of Embodiment 4, the first support column 2C and the second support column 3C are made of prismatic members, but are not limited to this. For example, each first support column 2C and each second support column 3C may be made by stacking multiple rectangular parallelepiped structures vertically and connecting them with bolts or the like. Each structure is made of plate-shaped metal, hard ceramic, or the like. With this configuration, the height of the first support column 2C and the second support column 3C can be easily changed by adjusting the number of stacked structures.

[0104] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of this disclosure. [Explanation of Symbols]
