Screw Jack

1. The screw jack is a combination of a turbine pair and a trapezoid screw rod to complete the lifting and lowering of objects. It has the features of compact structure, light weight, safety and reliability, long service life, convenient installation, etc., and has a self-locking function in the static state.

2. Suitable for heavy load, low speed, and low frequency;

3. Main components: precision trapezoid screw pair and high precision worm gear pair;

4. Compact design, small volume, lightweight, wide drive sources, low noise, easy operation, and convenient maintenance.
