It was necessary to secure an installation area and a storage space when not in use. Further, in the lifter, a space (pit) for installing the body of the lifter must be recessed on the floor of the spectator seat, and not only the cost of the lifter body but also the construction cost of the pit increases, so the overall equipment cost rises. In the auditoriums and concert halls where the stage is already established, the place where the lifter is installed is restricted, and the construction is often difficult due to other conditions.

41a) is extended to form a gentle slope extending approximately twice the height of the side wall. On the left and right side edges of the bottom of the loading platform 4, a substantially strip-shaped side wall supporting plate 42 extending in the front-rear direction extends, and one piece (lower piece) of a hinge 43 is fixed on the side wall supporting plate 42. The other piece (upper piece) of the hinge 43 is bendable only to the outside of the loading platform 4 and has a vertically long slot 44. The lower end of the inner rectangular plate 41 constituting the side wall 40 is overlapped with a pin 45 projecting from the lower end of the inner rectangular plate 41 on the rear surface of the hinge 43 not corresponding to the bending side (corresponding to the inside of the loading platform 4). The inner square plate 41 is slidably mounted on 44 and the inner square plate 41 is provided to the hinge 43 so as to be vertically movable. The outer square plate 41a is formed vertically longer than the inner square plate 41, and the upper end of the inner square plate 41 and the outer square plate 41a are formed.
When the side wall 40 is extended, the upper end of the outer rectangular plate 41a is overlapped with the upper end of the outer rectangular plate 41a when the side wall 40 is extended, and the extended state is maintained.
In addition, an upright wall 46 for holding the lower end of the outer rectangular plate 41a is arranged upright on the outer edge of the side wall support plate 42, and the upright wall 46 moves up when the outer rectangular plate 41a moves upward together with the inner rectangular plate 41. Board
The height is set so as not to obstruct the lower end of 41a, and the inner rectangular plate 41 is bent to the outside of the loading platform 4 and gently lowered from the floor surface 4a while extending the folded outer rectangular plate 41a during the upward movement. The step board V inclined is formed. In this embodiment, the side wall 40 is provided so as to be deformable on the tread plate V. However, the front wall 39 may be formed into a tread plate V with the same configuration as described above. At the rear end of the floor 4a of the loading platform 4, a band-shaped transition plate 47 having a lower end pivotally mounted in the width direction is provided. When not in use, the transfer board 47 is inclined to the loading platform 4 side, and when the loading platform 4 is raised and its floor surface 4a is located on the same plane as the stage floor S, it is rotated so as to push it outward. It lays down horizontally, closes the gap between the floor surface 4a and the stage floor S, and bridges from the floor surface 4a to the stage floor S.

からの昇降台車１の出し入れ時の負担をも軽減できる。An elevating device 3 provided between the carrier 4 and the traveling body 2 on which the carrier is installed has a link L,
L1 is provided with a parallel movement mechanism section 14, and a link L,
Since the loading platform 4 is configured to perform a parallel movement with respect to the traveling body 2 in accordance with the undulation of the L1, the loading platform 4 is always kept horizontal during the ascent and descent, and the load on the loading platform 4 can be transferred stably and safely. Since the transmission means 16 for raising and lowering the links L and L1 is connected to the drive source 15, the lifting and lowering of the bed 4 can be automated, and even heavy objects can be easily transferred between the seat and the stage S.
Further, since the supporting means 18 for urging the springs 17 linked in such a manner as to expand and contract in accordance with the undulations of the links L and L1 in the rising direction of the links L and L1 is provided, the lowering of the bed 4 where the links L and L1 fall down. In this state, the spring 17 contracts and accumulates the urging force of the links L and L1 in the rising direction, and when the driving source 15 raises the links L and L1, the accumulated springs.
The urging (restoring) force of 17 is released, and this urging force
Since the driving force from the drive platform 15 can be assisted, the load on the drive source 15 applied when the bed is raised can be reduced, and the drive source 15 can be reduced in size, and the weight of the lift truck 1 itself can be reduced.
The burden of loading and unloading the lift truck 1 from the vehicle can also be reduced.

ができる。The traveling body 2 is formed by forming left and right side walls 6, 6a parallel to the reciprocating linear track over the entire length, and running wheels 7, 8 before and after the left and right side walls 6, 6a. The vehicle stops 2 are fixed to the trailing end x of the rear wheel 8 and the trailing end y of the front wheel 7 of the rear wheel 8 which are set to correspond to the protruding and retracting positions X and Y of the loading platform 4, respectively. 4, the stop position at which the rear wheel 8 comes into contact with the bogie 10 corresponding to the advance position X of the carrier 4 when the lift truck 1 is pulled out of the storage section H is set. The carriage 4 is located at a position suitable for ascending and descending outside the stage S adjacent to the stage S. On the other hand, when the carriage 1 is pushed into the storage section H, the front wheels 7 are moved to the car stops 11 corresponding to the immersion position Y of the carriage 4. The lifting position of the lift truck 1 is stored in the storage unit H, and the front wall 39 of the lift truck 1 When become a flush with position, easy positioning of the lifting carriage 1 in each state in the correct, it is possible to improve the efficiency of loading and unloading operations of the lifting carriage 1. Further, a guide roller 12 circumscribing the left and right side walls 6, 6a is provided between the bollards 10, 11 so as to maintain the reciprocating linear trajectory of the traveling body 2, so that the hoisting carriage 1 can always be straightened in and out. At the same time, the respective stopping positions (the positions X and Y of the loading / unloading platform 4) at the time of the loading / unloading can be accurately determined, so that the loading / unloading operation of the lift truck 1 can be performed reliably.
