ABSTRACT:
An extendable conveyor unit supports the extendable units directly from the warehouse floor with a minimum amount of support structure. The extendable conveyor includes one or more extendable units, a stationary support for supporting the extendable units, and a conveying surface defined on an extended portion of the extendable units. The stationary support supports the extendable units between a fully extended position, wherein the extendable units extend from the support in the direction of the vehicle to be loaded and a fully retracted position in which the extendable units extend from the support in a direction opposite from the direction of the vehicle to be loaded. The conveying surface may be a gravity roller conveyor or it may be an endless belt. When the conveying surface is an endless belt, an elevating unit may be provided with the stationary support in order to elevate the conveying member above the extendable unit at the stationary support to match up with a discharge or receiving conveyor. A cable routing system to the extendable units includes an electrical cable running between the stationary support and an extendable unit over a sheave mounted to another extendable unit with the extendable units extended at a rate that maintains tension on the cable for all extendable positions of the extendable units.
