A hand wheel is a convenient solution for manually operating a jack when using machine screw jacks in intermittent positioning applications. Hand wheels are available in a range of diameters from 5 to 16 inches and can be adapted for use on jacks up to the 20 tons capacity model.
NOTE: Hand wheels do not include a brake and therefore are not for use with ball screw jacks. When using hand wheels with a jack that can back drive (12:1 and lower) an additional locking mechanism may be required to prevent "creep".

A Screw Jack also known as a Worm Screw Jack, is a device used to convert rotational motion into a "push-pull" linear motion. It utilises the property of a screw thread providing a mechanical advantage which means that it can be used to amplify force. The rotary movement can be supplied manually or thanks to the help of hydraulic or pneumatic motors. Or thanks to electric motors, like the induction motor!
The generic term screw jack or jackscrew generally refers to a product that utilises a gearbox assembly and a transmission medium (lead screw, ball screw or roller screw) which, through the use of a motor or hand wheel, converts this rotary motion into linear motion.
