Zoomlion Truck-mounted Crane Parts YD140101X Winch Balance Valve

Suitable for Zoomlion Truck-mounted Cranes 12 tons, 16 tons

Function:

The main functions of the balance valve of the truck-mounted crane winch include the following points:
1, speed limit and stabilization control: when the crane mechanism or load down, the sequence valve in the balance valve can make use of the balance of the spool, so that the hydraulic cylinder oil return volume to keep stable, so that the hydraulic cylinder to maintain a uniform speed movement, to avoid losing control of the heavy load down.
2, Preventing loss of control and maintaining stable position: the counterbalance valve can prevent the loss of control movement caused by external load, and ensure the stable position of the boom and the heavy load in the space.
3, Self-locking function: when the truck-mounted crane stops working or malfunctions, the counterbalance valve can self-lock to ensure that the actuating elements remain in place, avoiding loss of control of the equipment and improving safety.
4, reduce the hydraulic shock: balance valve by regulating the flow rate of hydraulic oil, can alleviate the impact of hydraulic shock, to ensure the smoothness and safety of the truck-mounted crane in the rapid operation.
5,Improve the operation precision and efficiency: the balance valve can automatically adjust the oil flow according to the load change, ensure the moving speed of the lifting arm is smooth, avoid the sudden acceleration or deceleration, so as to improve the operation precision and efficiency.
6, to prevent overload protection equipment: balance valve can sense the pressure changes in the system, when the load exceeds the rated range, by adjusting the direction and flow of oil flow, to prevent excessive rise in pressure within the system, to protect the hydraulic components.
In summary, the winch balance valve plays an important control and protection role in the hydraulic system of the truck crane to ensure the safe, stable and efficient operation of the equipment.
