16000 SERVICE/MAINTENANCE MANUAL INTRODUCTION

Boom Hinge Pins
See Figure 1-35, Figure 1-36, and Figure 1-37 for the
following procedure.
During normal operation the boom hinge pins solenoid valve
is motor spooled where both cylinder ports and tank port of
valve spool section are connected in center position. When
an accessory valve spool shifts, supply flow to the other
accessory valves is limited. The accessory system pressure
sender monitors accessory system pressure.
Power is available to hand-held wireless remote control
when engine is running and power button is pressed. The
boom hinge pins can not be engaged/disengaged until
hydraulic line are connected between crane and boom butt
and keeper plates from pins are removed.
When boom hinge pins switch is placed in the engage
position and held, an input voltage is sent to Node-1
controller. Node-4 controller sends a 24 volt output to enable
boom hinge pins solenoid HS-52 and shifts valve to the
engage position. Node-3 controller sends a variable zero to
24 volt output to enable accessory system proportional relief
solenoid HS-68.
Hydraulic fluid pressure at approximately 3,000 psi (204 bar)
flows to boom hinge pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters rod end of boom pin
cylinder, retracting cylinder rod to engage the boom hinge
pins. Hydraulic fluid from piston end of boom pin cylinder
leaves accessory system valve and returns to tank. When
boom hinge pins switch is released, valve returns to center
position. Node-3 controller sends a variable zero to 24 volt
output to disable accessory system proportional relief
solenoid HS-68.
When boom hinge pins switch is placed in the disengage
position and held, an input voltage is sent to Node-1
controller. Node-4 controller sends a 24 volt output to enable
boom hinge pins solenoid HS-53 and shifts valve to the
disengage position. Node-3 controller sends a variable zero
to 24 volt output to enable accessory system proportional
relief solenoid HS-68.
Hydraulic fluid pressure at approximately 3,000 psi (207 bar)
flows to boom hinge pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters piston end of boom
pin cylinder, extending cylinder rod to disengage the boom
hinge pins. Hydraulic fluid from rod end of boom pin cylinder
leaves accessory system valve and returns to tank. When
boom hinge pins switch is released, valve returns to center
position.
Front or Rear Rotating Bed Pins
See Figure 1-35, Figure 1-38, and Figure 1-39 for the
following procedure.
During normal operation the rotating bed pins solenoid valve
is motor spooled where both cylinder ports and tank port of
valve spool section are connected in center position. When
an accessory valve spool shifts, supply flow to the other
accessory valves is limited. The accessory system pressure
sender monitors accessory system pressure.
Power is available to hand-held wireless remote control
when setup remote mode is selected, engine is running, and
power button is pressed. The rotating bed pins can not be
engaged/disengaged until keeper plates from pins are
removed.
