Abstract
An inclined conveyor for transporting shopping carts between an upper floor and a lower floor. The inclined conveyor includes a continuous conveyor assembly having a conveyor belt including a plurality of spaced drive lugs that engage a shopping cart. The moving conveyor belt transports the shopping cart between the upper and lower floors. The inclined conveyor includes a jam detector that interrupts operation of the conveyor upon detection of a jam along the conveyor. The inclined conveyor further includes a front wheel alignment and turning system for rotating at least one of the front wheels 180 degrees to place both front wheels in a common aligned position so as to prevent unnecessary operation of the jam detector along the conveyor belt. The inclined conveyor further includes a cart travel correction device for maintaining proper engagement between a portion of the cart and one of the drive lugs on the conveyor belt.
