ABSTRACT:
Suspended conveyor systems frequently employ threaded spindles as the drive mechanism to transport trolleys within a track. The spindle cooperates with drive blocks positioned adjacent to wheels on the trolleys. To facilitate switching and turning of the trolleys with two sets of wheels, a modified spindle system is employed which has alternating threaded and non-threaded regions. The spacing of the threaded and non-threaded regions corresponds to the spacing between the sets of wheels on the trolley.
