摘要： 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 sensors that prevent operation of the conveyor assembly if a person is present at either the unloading end or loading end of the conveyor assembly. At least one cart arrester is positioned along the length of the inclined conveyor to prevent uncontrolled descent of a shopping cart along the length of the inclined conveyor.

摘要： 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.
