Product Description

Through our supplier partnership with Marzorati we are able to provide a range of screw jacks for a diverse and demanding set of applications.

A screw jack is a mechanical device used to lift heavy loads or apply a large amount of force with a relatively small input force. It consists of a threaded screw shaft, a handle or crank for turning the screw, and a housing to encase the mechanism. When you turn the screw, it moves up or down, depending on the direction of rotation, and this motion is used to raise or lower objects or provide mechanical advantage in various applications, such as in car jacks, industrial machinery, or construction equipment. Screw jacks are commonly used in situations where precise control or slow, steady movement is required.

The Marzorati screw jacks come in two different versions MAR - Mechanical Screw Jacks and SJM - Mechanical Screw Jacks.
