The most common jack is the worm gear screw jack, also referred to as a machined screw jack because the acme, or trapezoidal, lead screw is machined. In addition to the low cost and self-locking characteristics, another advantage of worm gear screw jacks, and all screw jacks, is the mechanical advantage achieved through the internal gear ratio resulting in the ability to lift, lower, push or pull a significant load with a relatively small amount of torque on the I/O shaft.

Worm gear screw jacks are perfect in multiple jack systems because the torsional deflection of connecting rods and couplings has little effect on the positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy-duty cycle applications. They also suffer from low travel rates or speed and low efficiency. However, the lack of efficiency inherent in worm gearing produces the self-locking benefit associated with worm gear screw jacks.

 

SWL Series worm screw Jack

The elevator combines a turbine pair and 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.
