Overhead Power & Free Conveyors have free trolleys that are
driven by power chains and carriers that transport the material
to a given location.
The carriers are attached to the free trolleys and are
normally engaged to the power chain by an attached pusher dog
assembly on the free trolley. The pusher dog can be disengaged
by a cam action in either the free trolley or the chain dog,
caused by accumulating behind another free trolley or by
engaging a stop blade. The chain continues to move while the
carrier becomes temporarily stationary until the free trolley
becomes re-engaged with the chain.
