Zoomlion Crane Parts Luffing and Retracting Valve 11105704

1010302782 fits the following models:

RT75-2

Function:

The luffing and telescoping valve of the crane is an important part of the hydraulic system, and its main role includes the following aspects:
1. Controlling the boom's telescopic and luffing movements
By controlling the flow direction and flow rate of the hydraulic oil, the luffing and telescopic valve can realise the adjustment of the luffing and telescopic angle of the boom. The telescopic action can change the length of the boom, so as to adjust the height and working range of the lifting weight. The luffing action changes the angle of the boom to raise or lower the load.
2. Keeping the load stable
The counterbalance valve in the luffing and telescopic valve can keep the load stable during the boom extension or luffing process, preventing the boom from falling quickly or shaking due to gravity. This function is critical to the safety and accuracy of the lifting operation.
3. Hydraulic locking function
The counterbalance valve can also act as a hydraulic lock when the boom stops moving, reliably locking the boom in any position and preventing accidental movement of the boom due to external force or leakage from the hydraulic system.
4. Adjustment of speed and pressure
The luffing and telescopic valve can regulate the speed of boom extension and luffing by controlling the flow and pressure of hydraulic oil, so as to improve the working efficiency.
5. Improve operational flexibility and safety
By precisely controlling the telescopic and luffing movements of the boom, the luffing and telescopic valve enables the crane to flexibly adjust the operating range under complex working conditions, while ensuring the safety and stability of operation.
In conclusion, the luffing and telescopic valve plays a key role in the hydraulic system of the crane, and is an important guarantee for the realisation of efficient and safe operation of the crane.
