Details of original drive:

Screw jacks were originally requested, but supplied the wrong speed for the lift.

Details of Dorris replacement drive:

Due to the maximum input speed of a worm gear screw jack being 1800 rpm, we requested a special ratio from Dorris in a 203TL which would support the 5000 lbs. load on the thrust bearings. The ball screw was attached to the 203TL output shaft with a hard coupling. 203TL05 with C-Face kit and special ratio.
