Winch is a kind of machine with vertically installed cable drum, which can wind but can't store ropes under power drive. It also refers to the winch whose rotating shaft is perpendicular to the deck, which is the self-protection and traction device of vehicles and ships.

Self-help and rescue can be carried out in harsh environments such as snow, swamp, desert, beach and muddy mountain road, and operations such as clearing obstacles, dragging things and installing facilities can also be carried out under other conditions.

It is an indispensable safety device for military and police, petroleum, hydrology, environmental protection, forestry, transportation, public security, border defense, fire fighting and other outdoor sports. Mainly used for off-road vehicles, agricultural vehicles, ATV all-terrain vehicles, yachts, fire rescue vehicles, road wreckers and other special vehicles and special vehicles.

According to the different driving forces of winches, there are mainly the following six types:

1, electric winch, is the most common winch. The winch is driven by the vehicle's own power system.

2.PTO winch uses the output power of transfer case as power source.

3. Hydraulic winch uses the power of vehicle and power steering system as its power source, and uses power steering pump to provide source power.

4. Wheeled winch is a relatively new winch system, that is, the driving force is provided by the wheel shaft.

5. Manual winches driven by the longitudinal or circular motion of human hands usually have little pulling force due to the limitation of manpower.

6. The design and working principle of pneumatic winch is the same as that of hydraulic winch, but the power is changed from compressed liquid to compressed gas.

According to their different uses, it can be divided into: ATV winch, off-road winch, truck winch, industrial winch and so on. According to the characteristics of some industries, there are waterproof winches and explosion-proof winches.

Extended data:

Winch using skills:

1, relay transmission

Receiving the signal from the remote controller, the inside of which is a complete circuit that can change the direction of the motor.

2. Rope guide

If it is necessary to use the lasso to work at a certain angle, the guide can guide the lasso directly to the drum.

3, lasso drum

The drum of the noose is driven by a motor, just like the drum wound with the noose. Its direction can be changed by remote control button. The heavy winch has heavy ropes, so the drum is relatively large.

Winch working mechanism

The car stores and drives the motor, and the rotation of the drum drives the transmission shaft, which in turn drives the planetary gears, resulting in a strong deceleration. The increased torque is transmitted back to the drum, which drives the lasso.

There is a clutch between the motor and the reduction gear, which can be switched by the handle. The braking device is in the drum, and when the lasso is tightened, the drum automatically locks.
