Description:
A lifting machine, also known as a Hoist, is a mechanical device used to raise, lower, and move heavy loads with minimal human effort. It is commonly used in construction sites, factories, warehouses, and workshops. Lifting machines can be manual, electric, or hydraulic and include equipment such as cranes, chain hoists, winches, and forklifts. They are built with strong components like hooks, chains or wire ropes, motors, gears, and supporting frames to safely handle heavy materials.

Operation:
The operation of a lifting machine is based on mechanical force or powered systems that generate lifting motion. When activated, the machine uses a motor, hydraulic system, or manual effort to wind a chain, rope, or cable around a drum or pulley system. This action creates an upward force that lifts the load attached to the hook. The operator controls the lifting, lowering, and positioning of the load using control switches, levers, or hand chains. Safety systems such as brakes and limit switches help prevent overload and ensure stable and controlled movement of heavy objects.
