Abstract
A shock absorbing tow bar for connection between the accumulating trolley and load carriage of a power and free conveyor system is disclosed. The tow bar includes one component that is connectable to the accumulating trolley and another that is connectable to the intermediate trolley of the load carriage. Limited relative shifting is permitted between the components of the tow bar. Moreover, the components are threadably intercoupled so that such relative shifting requires a screwing or unscrewing action that serves to cushion movement between the accumulating trolley and load carriage.
