B: Overview - technical parameters of sec-
ondary steering system
Overview - working principles of secondary
steering system
The check valve of secondary steering system is
closed to protect the pressure oil from flowing
back to the secondary pump during normal
operation of complete machine. If the steering
pump fails or engine fails, and complete machine
is energized for more than 30s, the speed of
complete machine is more than 5km/h\3.11mph,
at this time, the secondary steering runs
continuously for 60s, which is recyclable. The
secondary steering pump sucks up the oil from
the hydraulic oil tank, the oil flows through the
secondary steering check valve and meanwhile
closes the steering pump opening check valve
and then reaches the steering cylinder via priority
valve to achieve the secondary steering.
The secondary steering system can use manual
test. The manual test switch is located at right
upright of cab and is a momentary switch, which
is usually ON. When testing the secondary
steering system, the complete machine is
energized but not started, press the test switch
and the secondary steering indicator comes on,
the secondary steering pump starts and the
steering test can be performed.
