ABSTRACT:
A hoistway car for transporting wheeled carts between floor levels which includes mechanism for reversing the cart swivel wheels to facilitate off-loading of the cart while avoiding chafing or jamming of such swivel wheels. In the illustrated embodiments, the reversing mechanism comprises turntables at the plane of the car platform which turn in predetermined directions to control wheel swivel action. In one embodiment, the turntables rely on gravitational forces to initiate swivel action, and in another embodiment, the turntables are power-operated for inducing swivel action.
