However, a conveyor such as a slat conveyor or the like that circulates the cargo handling table in the longitudinal direction of the traveling path. Can also be configured. When the cargo handling table is constituted by a conveyor, when loading the lid, the forklift or crane loading the lid only needs to put the lid-loaded pallet from behind the pole trailer 7 to the rear end of the conveyor. That is, every time the pallet with the lid is put on the rear end of the conveyor from behind the pole trailer 7 by a crane or the like, the conveyor is rotated and the pallet is advanced by one pallet. The loaded pallets need only be placed on the rear end of the conveyor from behind the pole trailer 7, and the loading operation of the lid is easy. Also, when collecting the pallets after laying all the loaded lids, the pallets can be collected efficiently by receiving the pallets at the rear end while rotating the conveyor backward.
