Abstract
A chain is used in an automated transport system to propel free travelling trolleys riding along a rail toward designated workstations, the chain runs within a U-shaped recess in a track channel on wheels rotatably supported by axles carried by individual links of the chain. The wheels are formed from a self-lubricating material and the axle carried by each of the links of the chain have finished outer surfaces thereby substantially enhancing the pressure-velocity value of the chain so that the chain may be run at velocities greatly in excess of those velocities presently achieved by known chains used in such automated transport systems.
