Zoomlion Crane Parts Luffing Balance Valve R901178109/08470803733500B

Zoomlion ztc series medium and large tonnage cranes

Function:

The role of the crane luffing balance valve is mainly as follows:
1. Preventing the weight from falling by itself: when the crane stops working or is in a static state, the luffing balance valve can close the oil circuit and prevent the hydraulic oil from flowing back, so as to keep the boom stable under the condition of bearing heavy loads, preventing the heavy loads from falling by themselves due to the action of gravity, and avoiding any danger. Even if there is pressure fluctuation or other abnormal conditions in the hydraulic system, the counterbalance valve can ensure that the boom will not fall suddenly.
2. Control of luffing speed: By changing the opening size of the counterbalance valve, the flow rate of hydraulic oil can be adjusted, thus controlling the luffing speed of the boom. The operator can accurately control the lifting speed of the boom according to the actual working needs, so as to improve the accuracy and safety of the operation, especially when carrying out delicate operation or working in narrow space, the accurate control of the luffing speed is more important.
3. Maintaining stable system pressure: The balancing valve can maintain stable pressure in the hydraulic system and reduce pressure shock. When the boom load changes or is subjected to external interference, the balance valve can automatically adjust the flow of oil, so that the system pressure is maintained within the set range, to protect the hydraulic components from damage caused by excessive pressure, and extend the service life of the hydraulic system.
4. Realize load holding: in the process of lifting weight, the luffing balance valve can make the luffing cylinder lock in any position to ensure the stability of the crane, prevent the crane from continuing to fall, and play the role of load holding to ensure that the crane in the process of the safety and reliability of the operation.
In summary, the crane luffing balance valve plays a vital role in the operation of the crane, it can effectively prevent the heavy load from falling by itself, control the luffing speed, keep the system pressure stable and realize the load holding, so as to guarantee the safety, efficiency and stability of the crane operation.
