Difference between hydraulic winch and electric winch

Power source: The power of hydraulic winch comes from the hydraulic system. It transmits motion through the change of sealed volume, transmits power through the pressure inside the oil pressure, and converts the mechanical energy of the prime mover into the hydraulic energy of the oil pressure. The electric winch converts electrical energy into mechanical energy through the motor, that is, the rotor output of the motor rotates to drive the drum to rotate.

Application scenario: Hydraulic winches are mainly used in marine engineering, construction, water conservancy projects, forestry, mining, docks and other occasions that require large rated loads. Generally, winches with rated loads greater than 10T are designed as hydraulic winches. Electric winches are generally used in situations where the rated load is less than 10T. They are commonly used in material lifting or flat towing in construction, water conservancy projects, forestry, mining, docks, etc., and are mainly electric winches.

Rated load: Hydraulic winches are usually used for winches with larger rated loads. Generally, winches with a rated load of more than 10T to 5000T are designed as hydraulic winches. Marine hydraulic winches generally have rated loads less than 10T and can be designed as electric winches.

Working principle: The working principle of hydraulic winch is to use hydraulic oil as the working medium, transmit motion through the change of sealed volume, and transmit power through the pressure inside the oil pressure. Electric winch uses electric motor as the power, drives the drum through elastic coupling, three-stage enclosed gear reducer, gear coupling, and adopts electromagnetic system.
