Oil line diagram in bypass state:
Shuttle valve is used to guarantee two brake
circuits are not in interference with each
other. When one of circuits fails and the pres-
sure decreases, the circuit is closed under
spring force. Make sure that the brake circuit
with zero-failure still realize braking function.
At this time, the failed circuit is connected
with the charge valve, the pressure of B3 port
decreases, low pressure alarm switch of ser-
vice brake acts, the machine shall be stopped
immediately for inspection.
