A hand winch is a gear-driven winch wire rope drum that pulls cargo by turning the wire rope wound around it. It has an automatic brake device, which makes it safer when operating. When the winch wire rope is pulling the cargo and the winch drum remains stationary, the brakes are automatically activated. When various rescue work is required, the hand winch is another option besides the vehicle winch. Its advantage is that it is portable and can be connected from any direction of the car. Light and strong, galvanized, pressed steel structure, steel cables pull the pulley propelled unit through two built-in prongs. These prongs pull the steel cable when the winch is in forward mode and also act as an automatic braking system. The prongs lock automatically as the grip increases. The hand winch can also be used for lifting, and the lifting force is about 65% of the pulling force.
Manual winch is a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects, also known as a hoist. The winch can be used alone or as a component in machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large amount of winding rope and convenient displacement. It is mainly used for material lifting or flat dragging in construction, water conservancy projects, forestry, mines, docks, etc. The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet and pawl) to keep the weight in the desired position. Manual winches used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used in places with small lifting capacity, poor facility conditions or no power supply.
