The carriage lifting device 4 comprises a pair of left and right lifting platforms 4a, 4b for separately supporting projection floor parts 31a, 31b projecting to both left and right sides of a carriage body 24 having wheels of a carriage 1. Each lifting platform 4a, 4b is provided with a carriage support part 56 positioned below the projection floor parts 31a, 31b of the carriage 1 which moves between the inside and outside of the carriage lifting device 4 at the height of the lower side travel path 3. When the lifting platforms 4a, 4b are at an elevating limit height, the carriage 1 in which the projection floor parts 31a, 31b are supported by the carriage support parts 56 of each lifting platform is configured to be transferable and movable between an upper side travel path 2. |
