Therefore, the pallet can be swiveled and traversed easily with a simple structure.

Further, according to the third aspect of the invention, since the pallet rotating operation and the pallet traversing operation are switched by elevating and lowering the carrier, only one drive device is mounted on the carrier, and the carrier itself. Since the weight of the winch does not increase, it is not necessary to increase the hoisting capacity of the winch.

According to the invention described in claim 4, the pallet and the swivel plate are fixed to each other by placing the pallet on the left and right swivel plates by lowering the carrier carrying the pallet. Since the fixing projection is engaged with the pallet, the pallet can be positioned with respect to the swivel plate at the same time.

According to the fifth aspect of the invention, when the pallet is not fixed to the swivel plate, the stopper mechanism restricts the swivel of the swivel plate and the carrier on which the pallet is placed is lowered. If the pallet is fixed to the swivel plate, the carrier mechanism is further lowered to release the stopper mechanism so that the swivel plate and the pallet can swivel. can do.

According to the sixth aspect of the present invention, since the storage rack is provided with the locking mechanism for locking the pallet on the storage rack, the locking mechanism is released when the pallet is traversed by the carrier. As a result, the locking of the pallet on the storage rack can be released, and it is not necessary to increase the output of the drive device that performs the traverse operation of the pallet.

According to the seventh aspect of the present invention, when the carrier does not reach the position of the storage shelf for traversing the pallet, the pallet is locked to the storage shelf by the locking mechanism and the carrier is moved. When the pallet reaches the position of the storage shelf that performs the pallet traverse operation, the locking mechanism is released by the release mechanism provided on the carrier to perform the pallet traverse operation. The pallets on the shelves can be reliably locked.
