What is the hand winch? Introduction to the principle of hand winch

What is the hand winch?

The hand winch is a kind of manual winch with an automatic locking buckle. In some places, it is also called a brake winch. Hand winch is a kind of mechanical equipment. Because of its pulley block working principle, it can lift heavy objects, so it is widely used for loading and unloading goods.

Hand winch is also called manual winch, it is a kind of mechanical equipment that pulls goods by shaking the winch drum by hand. The winch wire rope drum driven by the gear pulls the cargo by rotating the wire rope wound on it. It has an automatic brake device, which makes operation safer. When the winch wire rope pulls the cargo and the winch drum remains stationary, the brake will automatically open.

Advantages of hand winch:

1. When various rescue points are needed, the hand winch is another option besides the vehicle winch.

2. Its biggest advantage is that it is portable and can be connected from any direction of the car. Light weight and strong, electroplated and pressed steel structure, the steel cable is driven by two built-in forks to pull the pulley to advance the unit.

3. These prongs pull the steel cable when the winch is in forward mode, and It is also an automatic braking system. The fork will automatically lock when the grip is increased. The hand winch can also be used for lifting (the lifting force is about 65% of the drag force).

Hand winch use:

The hand winch is a lifting tool suitable for many places. The hand winch can be used for self-rescue vehicles in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads. It can also perform operations such as clearing obstacles, dragging objects, and installing facilities for hand winches under other conditions. It is an indispensable safety device for military police, petroleum, hydrology, environmental protection, forestry, transportation, public security, border defense hand winches, fire fighting and other field sports.

Principle of hand winch:

The combination of small gears driving large gears can magnify the force several times to provide greater power. The hand winch pulls the cargo by shaking the winch drum by hand, and the gear-driven winch wire rope drum pulls the cargo by rotating the wire rope around it. It is equipped with manual steering and automatic braking device, which makes the operation safer. When the winch wire rope pulls the cargo and the winch drum remains stationary, the brake ratchet will engage with the load-bearing ratchet to act as a brake.
