ept offers high quality Best Price Worm Gear Hand Crank Screw Jack for Lifting Tables for your requirements. Important Note: The original actual pictures, videos, designs and molds came from the audited manufacturer and supplier –  ept ept Co.,Ltd. Don’t copy the pictures, videos, models, designs and drawing dimensions without ept permission.

Hand crank screw jack (also known as a hand crank jack screw, a hand crank screw lift, a hand crank worm gear screw jack, or a hand crank screw actuator) 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 crank screw jack has intermittent precisely positioning and self-loc ept feature for no creeping down without brake mechanism or loc ept systems. Note: Hand crank does not include a brake and therefore are not for use with ball screw jacks. 

Hand crank screw jack wor ept principle is worm screw (also known as input shaft) is rotated manually operated by a hand crank, worm gear is rotated by the worm screw, the trapezoidal lifting screw moves through the rotating worm gear. The hand crank screw jack linear motion speed of trapezoidal lifting screw depends on thread size and rotation ratio of worm gears. Hand crank is available in a range of diameters from 100mm to 900mm and can be adapted for use on screw jacks from 0.5 ton up to the 20 ton capacity model, if larger than 20 ton capacity models, we don’t suggest use hand crank manually operated.  

In order to precise position display of the travel length, the hand crank 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.
