An overhead chain hoist is a type of lifting equipment that is used to lift and move heavy objects in industrial settings. It consists of a motor, a gearbox, and a chain that is used to lift and lower the load. The hoist is typically mounted onto a beam or track system that runs along the ceiling or overhead structure of the building, providing a wide range of motion for lifting and moving heavy loads.

Overhead chain hoists are commonly used in manufacturing plants, construction sites, and warehouses where heavy objects need to be lifted and moved over a short distance. They are ideal for operations that require a high degree of precision and control, such as loading and unloading materials from trucks or positioning heavy machinery.

Overhead chain hoists come in a variety of types and sizes, ranging from small manual hoists that can be operated by hand to large automated systems that can lift and move loads weighing several tons. They can be powered by electricity, air, or hydraulics, and can be customized to meet the specific needs of a particular application.
