Telescopic Beam Hinge Pins
See Figure 1-61 and Figure 1-62 in the following procedure.
The telescopic beam hinge pin cylinders has a three position
spool valve that is motor spooled where both cylinder ports
and tank port of valve spool section are connected in center
position.
The accessory system pressure sender monitors accessory
system pressure.
Power is available to hand-held wireless remote control
when, engine is running, MAX-ER function mode is selected,
and power button is pressed. Telescopic beam hinge pins
can not be engaged/disengaged until electrical cables and
hydraulic lines are connected between rear of crane and
telescopic beam of MAX-ER (3 and 6, Figure 1-52
). Remove
beam locking pins from engaged position.
When beam hinge pins switch is moved and held in
disengage (out) position, an input signal from wireless
transmitter is sent to a receiver on the crane. The receiver
sends the input signal to Node-1 controller. Node-7 sends a
24 volt output to enable telescopic beam hinge pins solenoid
HS-91 and shifts valve to disengage position.
Node-3 controller sends a variable zero to 24 volt output to
enable accessory system proportional relief solenoid HS-68
for a system pressure of 400 psi (28 bar) to hinge pin
cylinders.
Hydraulic fluid pressure at approximately 400 psi (28 bar)
flows to telescopic hinge pin accessory valve. Hydraulic fluid
leaves the accessory valve and enters rod end of beam pin
cylinders, retracting cylinder rod to disengage beam hinge
pins. Hydraulic fluid from piston end of beam hinge pin
cylinders leaves accessory system valve and returns to tank.
When beam hinge pins switch is released, an input signal is
sent to Node-1 controller. Node-7 controller sends a zero volt
output to hydraulic solenoid HS-91 to return valve to center
position.
Node-3 sends a variable voltage output to accessory system
proportional relief solenoid HS-68 to provide approximately
3,000 psi (207 bar) system pressure.
