Abstract
A conveyor chain for a dishwashing system which chain includes a plurality of pinned links and travels on a conveyor pan and supports at least in part racks to be carried. The links are pinned for movement about a vertical axis (in a horizontal plane). Paired wheels are pinned to the links and lie in planes that form acute angles with the pan. This minimizes lateral sliding friction between the wheels of the links and the pan and therefore, wear, when the chain travels through a non-linear portion of the pan.
