ABSTRACT:
A mechanical drive for transporting a load attached to a load carrier element displaceable along a rotary threaded shaft between unthreaded ends of the shaft features precision end-of-travel positioning of the load and is improved to eliminate vibration of the load carrier element against the end of the thread on the rotating shaft thereby reducing wear of both the thread end and the load carrier.
