Introduction to the principle of hand winch
A hand winch is a kind of manual winch with an automatic locking buckle, some places are also called brake winch. A hand winch is a mechanical device, because it has a pulley set working principle, and can be lifted heavy objects, so widely used in cargo handling.
A hand winch, also known as a hand winch, is a mechanical device, it is by hand winch reel to pull the goods. The gear-driven winch rope drum pulls the goods by turning the wire rope wound on it. It is equipped with an automatic brake, which makes it safer to operate. When the winch rope is pulling the load and the winch drum remains motionless, the brake employment is automatically turned on.
Hand winch advantages:
1. When the need for a variety of rescue advantages aids work, hand winch is the car winch outside another choice.
2. Its advantage is that it can be portable, and can be connected from any direction of the car. Lightweight and solid, electroplated, pressed steel construction, steel cable through the two fixed fork head pull pulley propulsion unit.
3. These forkheads pull the steel cable line when the winch is in forward mode and also act as an automatic braking system. The fork heads automatically lock when the grip increases. The hand winch is also capable of being used for lifting (lifting force is about 65% of the towing force).
Hand Winch Uses:
The hand crank winch is a lifting tool for many locations. Hand crank winch can be in the snow, swamps, deserts, beaches, muddy mountain roads, and other harsh environments for vehicle self-rescue, and may be in other conditions, clearing, dragging items, hand crank winch installation facilities, and other operations, is the military and police, petroleum, hydrological, environmental protection, forestry, transportation, public security, border guard hand crank winch, firefighting, and other field campaigns indispensable safety devices.
Hand crank winch principle:
The combination of small gears driving large gears can amplify the force several times to provide greater power. The hand winch is used to pull the load by cranking the winch drum by hand, and the gear-driven winch wire rope drum pulls the load by turning the wire rope wound on it. It is equipped with a manual steering automatic brake, which makes it safer to operate. When the winch rope is pulling the load and the winch drum remains stationary, the brake ratchet bites into the load-bearing ratchet and acts as a brake.
