Conveyor chain structure

摘要

A conveyor structure including a power track on which a conveyor chain is supported and a free track along which free trolleys travel. The conveyor chain includes alternate center or main links that are pivotally interconnected by alternate pairs of side links through pivot pins. The construction of the links and pivot pins is such that the links and pivot pins can be disconnected without the use of tools. One of the lower links has a pusher dog thereon and is constructed and arranged to permit removal and assembly thereof without the use of tools with respect to the remainder of the chain.
