Product Description

Manufacture and Sale hand operated screw lift 1-tons force 24:1 ratio manual acme screw jack.

Worm gear screw jacks are very good in multiple jack systems, because the torsional deflection of connecting shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications. They also suffer from low travel rates or speed and low efficiency.
