Product Introduction of Mechanical Screw Jack
Screw jacks are driven by humans through screw pairs, and screw or nut sleeves are used as jacking parts. Ordinary screw jacks rely on screw self-locking to support heavy objects, and their structure is simple, but the transmission efficiency is low and the return is slow. The screw of the self-lowering screw jack has no self-locking action and is equipped with a brake. Relieve the brakes, and the weight can quickly drop by itself, shortening the return time, but the structure of the jack is more complicated. Screw jacks can support heavy loads for a long period of time. The maximum lifting capacity has reached 100 tons and it has been widely used. After installing the horizontal screw on the lower part, it can also make the heavy object to traverse small distance.
Main Application of Mechanical Screw Jack
The Screw jack is a kind of lifting tool commonly used in the repair and installation of automobiles, bridges, ships, and machinery. Hook-type screw jacks can use hooks to lift lower-heavy weights.
