Hand winch, also known as manual winch, is a mechanical equipment, it is by turning the winch by hand to drag items. A winch wire rope reel driven by a transmission gear pulls items light and strong by turning the wire rope wound above it, electroplating, pressing the steel frame structure, and the cable pulls the pulley-driven unit with two predetermined fork heads. These head in the winch forward form of the process of dragging the cable, at the same time is an automatic braking system. The head locks automatically as the grip increases.
When the winch wire rope is pulling on the item and the winch drum is not moving, the brake task automatically opens. Manual winches are an alternative to vehicle winches when various rescue tasks are required. It is characterized by its portability and can be connected from different directions in the car. In addition, the company also produces and manufactures pneumatic winches, which can drag heavier objects driven by air motors to meet the needs of daily work tasks.
Hand winch Advantages:
1. When a variety of rescue advantages aid work is needed, the hand winch is another choice outside the vehicle winch.
2. Its biggest advantage is that it can be portable and can be connected from any direction of the car. Lightweight and strong, electroplated, pressed steel structure, steel cable through two preset fork heads pull pulleys to propel the unit.
3. These forks pull the cable line when the winch is in forward mode, and are also an automatic braking system. The fork head locks automatically as the grip increases. The hand winch can also be used for lifting (lifting force is about 65% of the drag force).
Use of hand winch:
Hand winch is a kind of lifting tool suitable for many places. Hand winch can be used in snow, swamps, deserts, beaches, muddy mountain roads and other harsh environments for vehicle self-rescue, and may be under other conditions, clearing, dragging items, hand winch installation facilities and other operations, is the military police, petroleum, hydrology, environmental protection, forestry, traffic, public security, border hand winch, fire and other field sports indispensable safety devices.
Hand winch principle:
The combination of small gears driving large gears can amplify the force several times in order to provide greater power. A hand winch is used to pull the goods by moving the winch drum by hand, and a gear-driven winch wire rope drum pulls the goods by turning the wire rope wound around it. It comes with manual steering and automatic braking, which makes it safer to operate. When the winch wire rope pulls the goods, and the winch drum remains motionless, the brake ratchet will bite the load-bearing ratchet and play a braking role.
