Abstract
A conveyor system is disclosed which is adapted to be suspended from an overhead monorail and which includes a plurality of carriages each having an open longitudinal portion extending therethrough. Each of the carriages interconnect one to another in a single file fashion so as to be moved as a unit below and along the overhead monorail. The conveyor belt is supported and carried by the carriages. An improved power transmission device is connected to at least one of the carriages for moving the plurality of carriages along the overhead monorail. The power transmission device means includes a pair of transversely spaced apart rotatable drive wheels which are drivably coupled to and which support a pair of transversely spaced apart power units. The power units are pivotally connected below the drive wheels. A hydraulic system is provided for pivoting the power units toward and away from one another to maintain the drive wheels in traction relationship with the overhead monorail.
