Introduction to the Principle and Application of Hand Winches

A hand winch is a mechanical device that uses human power to pull or lift heavy objects. Its core principle lies in the combination of gear transmission and self-locking mechanism.

Advantages of hand winch:

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

2. Its greatest advantage is portability. It can be connected from any direction of the vehicle. It is lightweight and sturdy, with electroplated and pressed steel structure. The steel cable is pulled by two internal heads to drive the pulley unit.

3. These heads pull the steel cable when the winch is in the forward mode and also serve as an automatic braking system. The heads will automatically lock when the grip force increases. The hand winch can also be used for lifting.

The uses of hand winch:

A manual winch is a lifting tool suitable for various places. It can be used for vehicle self-rescue in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads. It can also be used for clearing obstacles, dragging items, and installing facilities under other conditions. It is an indispensable safety device for military, police, petroleum, hydrology, environmental protection, forestry, transportation, public security, border defense, fire control, and other outdoor activities.

The principle of hand winch:

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

Hand winches are not commonly seen in people's daily lives, but they can be found in many construction sites. Hand winches are very convenient tools that can help solve many problems. For example, hand winches are excellent labor-saving tools that play a significant role in many high and low transportation processes. Moreover, manual winches are indispensable tools in many construction fields, providing relief from physical labor for people.
