Installation & Spindle Screw Type

Translating screw: A driven worm shaft acts on an internal worm gear, which in turn drives a lifting screw to extend or retract. As the lifting screw translates through cast iron housing, then worm gear and lifting screw rotate together. When the lifting screw is held to prevent rotation, the lifting screw will move linearly through the cast iron housing to move the load.
Keyed screw: Some loads don’t prevent lifting screw rotation. These applications require a keyed screw jack. A key, fixed to the jack housing and inserted into a keyway milled into the lifting screw, forces the lifting screw to translate without rotating.
Rotating screw: A lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate,but not translate. A traveling nut, attached to the load, is driven by the rotation of the lifting screw. This type jack is ideal for applications that can not accommodate a screw protective tube and save enough mounting space.
