Product Description
Zoomlion Crane Parts Crane Truck Crane Parts Duplex Winch Brake Pilot Valve ,Suitable for Zoomlion cranes 25 tons, 30 tons, 35 tons, 50 tons and 70 tons.
Function:
The function of the crane duplex winch brake valve is to **control the lifting and lowering speed of the winch mechanism to ensure smooth and safe operation. The following are its specific functions:
1. Precise control of speed: Through this brake valve, the rotational speed of the winch motor can be precisely controlled, so as to realize the precise adjustment of the lifting and lowering speed of the heavy loads, and meet the operational requirements under different working conditions, whether in fine lifting operations or rapid loading and unloading tasks, which enables the operator to better control the lifting and lowering speed of the heavy loads.
2. Preventing overspeed and stall: when the weight is falling, the brake valve can limit the speed of the winch motor, preventing the weight from accelerating down due to gravity, avoiding the dangerous situation of overspeed and stall, and guaranteeing the safety of operation; and when the weight is lifting up, it can also prevent the weight from rising up too fiercely due to the motor's speed, which may cause accidents.
3. Realize smooth starting and stopping: when the winch mechanism starts and stops, the brake valve can effectively control the torque output of the motor, so that the heavy load can start to rise or fall smoothly, and stop smoothly when it reaches the specified position, reducing the shaking and impact generated by inertia, and improving the stability and accuracy of the lifting operation.
4. Adapt to different loads: different lifting operations may face different load conditions, the duplex winch brake valve can automatically adjust the output of the winch motor according to the size of the actual load, so that the system can maintain stable operation under different loads, to ensure that lifting operations are carried out smoothly.
5. Protecting hydraulic system: By controlling the speed and torque of the winch motor, it reduces the pressure impact and the sudden change of flow of the hydraulic system, reduces the wear and damage risk of the hydraulic components, and prolongs the service life of the hydraulic system, and at the same time, it also improves the reliability and stability of the system.
To summarize, the crane duplex winch brake valve plays a vital role in the crane's winch mechanism, which can not only ensure the safe and efficient conduct of lifting operations, but also improve the handling performance and service life of the crane.
