Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks. Mechanical capacity of screw jacks is between 5kN and 2000kN, Jack screws can be used as linear motors, linear actuators, or mechanical lifts depending on type of motion.


Working Principle of Screw Jacks


Main components of screw jacks are: trapezoidal lifting screw, worm screw, worm gear and gear housing, Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

Hand Operated Screw Jack for Crank Table
Hand Operated Screw Jack for Crank Table

The working principle of the hand operated  worm gear screw jack is that the worm (also called the input shaft) is manually rotated by the hand wheel, the worm wheel is rotated by the worm, and the trapezoidal lifting screw is moved by the rotating worm wheel. The linear motion speed of the  worm wheel manual screw jack trapezoidal lifting screw depends on the thread size and the worm gear speed ratio. Hand Operated Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack.It is ideal solutions for applications where electricity or power generators is inconvenient or dangerous. Our Jack's Advantages: -Self-locking ability -Can be driven directly by hand wheel -Can be customized according user's demand -Compact configuration, small size, lightweight -Convenient installation, flexible operation -High reliability and stability -2 / 3 /4 /8 sets etc. screw jacks to linkage to use  Please see a short video about hand operated screw jack for crank table below,
