A worm gear hoist is a type of mechanical lifting device that uses a worm gear mechanism to lift and lower loads through a rope and pulley system. The worm gear, which consists of a rotating helical gear known as the 'worm,' meshes with a gear wheel called the 'worm gear,' transferring torque and lifting heavy weights in a smooth and controlled manner. This type of hoist is ideal for various applications, such as construction sites, factories, and shipping yards.
