Product Description
Zoomlion crane parts crane truck crane winch motor,Suitable for Zoomlion cranes 25 tons, 30 tons, 35 tons, 50 tons and 70 tons.
Function:
Crane winch motor plays a vital role in crane operation, mainly reflected in the following aspects:
1. Realization of heavy lifting: hydraulic motor is the executive element in the winch mechanism, driven by the pressure oil provided by the hydraulic pump, which transmits the torque and movement to the drum, thus realizing the lifting and lowering movement of the heavy load. Generally the main winch uses a plunger swash-axis variable motor, and the secondary winch uses a plunger quantitative motor.
2. Control of lifting and lowering speed: The winch motor can accurately control the lifting and lowering speeds of heavy loads according to the demands of different working conditions. For example, in the lifting of small tonnage weight, the motor is required to have “high speed, low torque”; while in the lifting of large tonnage weight, the motor is required to have “low speed, high torque”.
3. keep the weight still: when need to make the weight stay in the air in a certain position, the winch motor can through the balance valve and other devices, lock the drum rotation, prevent the weight due to gravity and fall, to ensure the safety and stability of the operation.
In conclusion, the crane winch motor is the key component in the crane winch system, which is vital for the normal operation and safe operation of the crane.
