1. A hand wheel is a convenient solution for manual operated a screw jack or screw jack systems. When using screw jacks in intermittent positioning applications. Hand wheels are available in a range of diameters from 125mm~500mm and customized follow clients' need.
Hand Wheels do not include a brake. Hand wheels are not recommended for use with ball screw jacks. When using hand wheel with a screw jack that can backdrive an additional locking mechanism may be required to prevent "creep".

2. For precise position display, a range of digital counters are available for use with screw jacks. These digital counters measure the rotation of the input shaft and display corresponding position in a counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different jack ratios, lifting screw pitch and travel distances.
