Product Description

Screw jack, also known as mechanical jack, is driven by manpower through a screw pair, with a screw or nut sleeve as the lifting piece. Ordinary screw jacks rely on the self-locking effect of the thread to support heavy objects. They have a simple structure, but low transmission efficiency and slow return. The thread of the self-lowering screw jack has no self-locking effect and is equipped with a brake. When the brake is released, the heavy object can be quickly lowered by itself, shortening the return time, but the structure of this jack is more complicated. Screw jacks can support heavy objects for a long time, with a maximum lifting capacity of 100 tons, and are widely used. After the horizontal screw is installed on the lower part, the heavy object can also be moved horizontally for a small distance.
