Operation Principles for Off-road Winch

However, the power in the off-road winch is generally only a few horsepower. So why such a small power motors can also drag a heavy car or other heavy objects? The secret lies in the use of gear. Even the power generated by the motor is small, but the gear can transform in into strong power. So some manufactures just take advantage of this theory to make off-road winch.

Most off-road winches on the market are made of planetary gear reducer. Planetary gear has the advantage of small body and producing relatively large reduction ratio, and having many the gear contact points Off-road winch is usually mounted on a more narrow space. So the smaller and the lighter, the better. Gear can achieve this requirement, while also generating a large reduction ratio, so it's very popular.

In a short, the off-road winch internal working mechanism is: the electric power from the car to drive the motor, and the motor make the drum move, drum move the axis, axis move the gear axis, then to produce strong torque. Subsequently, the torque is transferred back to drums, then the off-road winch was moved by the drum. Between the motor and a clutch gear, there is a handle to switch.

In practice, some aids are essential for safely using the off-road winch, such as gloves to protect hands. In addition, if we want to fix the off-road winch to a tree, a piece of string, a u-shaped lug, and a tight line pulley are needed. String is used to fix the fulcrum, and its ideal length is 1.5-2. O meters; u-shaped lug can connect the hook and string with the  off-road winch.
