Product Description

Zoomlion Crane Insertion Bidirectional Hydraulic Lock/Buch DERV8-B

Function:

The role of inserted hydraulic lock for large tonnage crane mainly has the following aspects:
1. prevent the weight from sliding down by itself: when the oil pump stops supplying oil or the reversing valve is in the neutral position, the inserted hydraulic lock can close the inlet and outlet of the cylinder and prevent the pressure oil from leaking, so that the load cylinder can remain stable in both directions, preventing the sliding down by itself due to the action of the heavy load and ensuring the safety and stability of the crane in a static state.
2. Pressure maintaining function: in the locking circuit with long supporting time and low movement speed, such as the crane's outrigger expansion and contraction and other working conditions, the inserted hydraulic lock can effectively maintain the pressure inside the cylinder, preventing the piston position from changing due to the change of the internal pressure, and guaranteeing the normal work of the machinery.
3. Improve system reliability: By preventing the pressure oil from leaking and the weight from slipping, the inserted hydraulic lock helps to improve the overall reliability of the hydraulic system of the crane, reduce the possibility of malfunctioning and prolong the service life of the equipment.
4. Enhance operational safety: During crane operation, the inserted hydraulic lock can provide reliable locking function at critical moments, providing safety guarantee for the operator and avoiding dangers such as loss of control of heavy loads or destabilization of the crane due to unforeseen circumstances.
To sum up, the inserted hydraulic lock of large tonnage crane plays an important role in preventing the heavy load from sliding down by itself, keeping pressure, improving the reliability of the system as well as enhancing the safety of operation.
