Lifting Screw الموردين

A lifting screw, also known as a screw jack or jackscrew, is a mechanical device used to lift or move heavy loads with minimal effort. It operates on the principle of the screw, which converts rotational motion into linear motion. The main components of a lifting screw include a threaded screw shaft and a nut, which is often referred to as a worm gear or drive nut. When the nut is rotated, it moves along the threads of the screw shaft, causing the shaft to move linearly either upwards or downwards, depending on the direction of rotation.

Lifting screws are commonly made from high-strength materials like steel or stainless steel to ensure durability and the ability to handle significant loads. They come in various designs, including machine screw jacks and ball screw jacks, each suitable for different applications based on load capacity, speed, and efficiency requirements.
