図ることができる。 With this structure, the lifting platform 1 is raised and lowered by the driving of the lifting cylinder 5, but since the pinions 10 meshing with the pair of racks 8 are integrally connected in the longitudinal direction, synchronization of the raising and lowering can be obtained. In the width direction, a double sprocket 14 engages with vertical chains 18 on both sides fixed to the lifting platform 1.
Since they are connected to each other by a horizontal chain 16, synchronization of lifting and lowering can be obtained. Therefore, the lifting platform 1 can be raised and lowered without tilting in both the longitudinal direction and the width direction. Therefore, when constructing a panel frame or the like on the lifting platform 1, the work can be performed with high precision. Further, since the width direction tuning mechanisms 7a and 7b are composed of chain mechanisms, the structure is simple and can be manufactured at low cost. Since the longitudinal direction tuning mechanisms 6a, 6b are rack and pinion mechanisms, the width direction tuning mechanisms 7a,
Although it requires some more expensive parts than 7b, since there is no part protruding above the lifting table 1, interference can be avoided when carrying objects into and out of the lifting table 1. In this way, since the width direction tuning mechanisms 7a and 7b are constructed by chain mechanisms, and the longitudinal direction tuning mechanisms 6a and 6b are rack and pinion mechanisms, it is possible to simplify the structure and also facilitate the loading and unloading of objects. I can do it.
