A subsidiary work station loop for a work station conveyor system has a gravity fed rail assembly for trolleys shunted from the main conveyor. An elevator returns the trolleys from the lower end of the rail assembly. Four rail segments define this rail assembly and three of the four are supported by a single bracket and a single fastener. The rail segments are coupled by a pin and slot connection that permits limited angular rotation of one segment relative to the other, but which prevents relative axial misalignment.
There is disclosed a wiring harness assembly line wherein a member supply line (2) including a looped track (20) and hangers (30) movably suspended from the track (20) is provided on the outer periphery of a plate supply line (1) so that the hangers (30) pass through a work space of an operator at an assembly position, whereby the member supply line is adapted to replenish a plate for wiring with members such as sub-assemblies.
