Product Description

JACTON Manual Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack, which has intermittent precisely positioning and self-locking feature for no creeping down without brake mechanism or other locking systems, when manual ball screw jack, no self-locking feature, avoid ball screw back drive with attached load, which needs additional brake mechanism or other locking system to prevent it creep. When hand operated screw jack need 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 screw jack ratios, screw pitch and travel length.

JACTON offers high quality Hand Wheel Screw Jack for Vintage Industrial Crank Table or Standing Desk for your requirements. Important Note: The original actual pictures, videos, designs and molds came from the audited manufacturer and supplier - JACTON Industry Co.,Ltd. Don't copy the pictures, videos, models, designs and drawing dimensions without JACTON permission.

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.
