3-Jacks Power Worm Gear Table Lifts

A three point lift system was devised using three screw jacks, bevel gearboxes, couplings and drive shafts. The system was designed to be quick and easy to use by hand operation while being self-locking. Using metric machine screw jacks on the screw provided a mechanism that was self-locking and minimum torque input for hand operation.
