A handwheel is a convenient solution for manual operating a jack when using machine screw jacks in intermittent positioning applications.
Important note: If hand operated screw jack needs precise position display, a range of digital position indicators are available. These digital position indicators measure the rotations of the input shaft and display corresponding position in the digital counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different worm gear ratios, screw pitch and travel stroke.
