Introduction to 4 major categories of logging winches

Logging winches can be divided into: manual, electric, pneumatic, and hydraulic.

Manual winch

The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet wheel and pawl), so that the heavy object can be kept in the required position. The manual winch used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. It is generally used in places with small weight, poor facility conditions, or no power supply.

Tời điện

Những điện tời is mainly driven by a motor through a reducer to drive the drum, and a brake is installed between the motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotation, there are also double-drum and multi-drum winches. Generally, a winch with a rated load lower than 10T can be designed as an electric winch.

Mainly used in places with heavy work and large traction requirements.

Pneumatic winch

The pneumatic winch uses compressed air as the power source, outputs torque through a piston-type pneumatic motor, and drives the drum through two sets of internal and external gear transmission pairs to drive the operation of the drum to achieve its hoisting purpose. Its main structure includes air motor, gear box, roller and brake, etc. All transmission parts are supported by high-quality ball bearings, which are flexible in operation. The main parts are mostly made of high-strength high-quality alloy steel, and through heat treatment process, the parts have a longer service life.

Hydraulic winch

The hydraulic winch is mainly composed of a distributor (composed of a valve group such as a one-way balance valve and a high-pressure shuttle valve to control the brake), SNM hydraulic motor, brake, planetary reducer, reel, frame, support shaft assembly, clutch, etc. Component composition. The oil is used as the working medium, and the movement is transmitted through the change of the seal volume, and the power is transmitted through the pressure inside the oil.
