Function:

The counterbalance valve of the crawler crane plays a vital role in the hydraulic system, which is mainly reflected in the following aspects:
1. Preventing uncontrolled falling of heavy loads
The counterbalance valve can prevent the hydraulic cylinder from unwanted downward movement under the action of gravity, ensuring that the heavy load can be lifted and stably maintained in a certain position. In the event of a sudden loss of pressure in the hydraulic system, the counterbalance valve will act as a hydraulic lock to keep the weight immobile.
2. Control the speed of descent
Counterbalance valve through the control of hydraulic oil return back pressure, adjust the hydraulic cylinder or hydraulic motor speed, so as to achieve a smooth control of the falling speed of the weight, to avoid over-speed falling due to the weight of the potential safety hazards caused by the fall.
3. Maintain the stability of the hydraulic system
Balance valve can ensure that the hydraulic system remains stable when the load changes, preventing the uncontrolled action of hydraulic cylinders or hydraulic motors triggered by the load energy, thus eliminating the phenomenon of air pockets and uncontrolled load phenomenon.
4. Improvement of operational safety
In the event of a line burst or serious leakage in the hydraulic circuit, the counterbalance valve can prevent the uncontrolled movement of the moving load to ensure the safety of the operation process.
5. Optimise energy utilisation
Balance valve through the reasonable pressure and flow control, optimise the energy efficiency of the hydraulic system, improve the operating efficiency of the crawler crane.
6. Prevent reverse movement of hydraulic cylinder
Counterbalance valve has the function of one-way valve, when the rodless chamber of the hydraulic cylinder returns oil, it needs to overcome the set pressure of the counterbalance valve to open the spool, so as to prevent the hydraulic cylinder from reverse movement due to external force.
In summary, the counterbalance valve in the hydraulic system of crawler crane not only protects the safety and stability of operation, but also improves the accuracy and efficiency of operation.
