YS40-35 bidirectional hydraulic lock
Double Direction Hydraulic Lock, Bidirectional Hydraulic Lock, Hydraulic Brake Control Valve
Application
It is mainly applied to the oil system of hydraulic leg of truck crane, hydraulic aerial vehicle and piling machinery and also other hydraulic machinery.
- Combined by two pilot controlled check valves, with good locking performance
- It can be applied in various engineering machinery, automobile crane, automobile lifter, large or flexible fork truck, driller, urban planning machinery, forest machinery and fixing equipment etc. heavy object supporting system requiring good double direction locking performance.
Functions and features
1. When the leg is lowered, the hydraulic lock can prevent leg shrinkage due to oil leakage. In case of a broken oil pipe, it can avoid an accident caused by leg failure. When the crane truck or hydraulic aerial cage drives or parks, it can guard the leg against gliding due to self weight.
2. It enjoys features like sensitive reaction, reliable working, small volume and light weight.
3. The valve make make sure hydraulic leg go down less than 1mm in 24 hours.
