Hand Wheel Screw Jack for Vintage Industrial Crank Table or Standing Desk

Hand wheel screw jack (also known as a hand wheel worm gear screw jack, a handwheel manual screw jack, or a hand operated screw jack) is the most economical and efficient mechanism for lifting and lowering loads, for push-pull applications where electricity or power generators is inconvenient or dangerous. Hand wheel screw jack has intermittent precisely positioning and self-locking feature for no creeping down without brake mechanism or locking systems. Note: Hand wheels do not include a brake and therefore are not for use with ball screw jacks.Hand wheel screw jack working principle is worm screw (also known as input shaft) is rotated manually operated by a hand wheel, worm gear is rotated by the worm screw, the trapezoidal lifting screw moves through the rotating worm gear. The hand wheel screw jack linear motion speed of trapezoidal lifting screw depends on thread size and rotation ratio of worm gears. Handwheels are available in a range of diameters from 100mm to 900mm and can be adapted for use on screw jacks from 1 ton up to the 20 ton capacity model, if larger than 20 ton capacity models, we don't suggest use handwheels manually operated.In order to precise position display of the travel length, the hand wheel screw jack worm screw adds a digital position indicator which measures the rotation of the worm screw and display a 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 screw jacks worm gear ratios, screw pitch and travel distances. Note: not for use with motorized applications.
