Boom Hinge Pins
See Figure 1-33 and Figure 1-34.
During normal operation the boom hinge pins solenoid valve
is motor spooled where both cylinder ports and the tank
port of the valve spool section are connected in the center
position. When an accessory valve spool shifts, the supply
flow to the other accessory valve is limited. The accessory
system pressure sender monitors the accessory system
pressure.
Power is available to the hand-held wireless remote control
when the engine is running, and the power button is pressed.
The boom hinge pins cannot be engaged/disengaged until
the hydraulic line is connected between the crane and the
boom butt and the keeper plates from the pins are removed.
When the boom hinge pins switch is placed in the engage
position and held, an input voltage is sent to the Node-1
controller. The Node-4 controller sends a 24 volt output to
enable the boom hinge pins solenoid HS-52 and shifts the
valve to the engage position. The Node-3 controller sends a
variable 0 to 24 volt output to enable the accessory system
proportional relief solenoid HS-68.
Hydraulic fluid pressure at approximately 204 bar (2,959 psi)
flows to the boom hinge pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters the rod end of the
boom pin cylinder, retracting the cylinder rod to engage the
boom hinge pins. Hydraulic fluid from the piston end of the
boom pin cylinder leaves the accessory system valve and
returns to the tank. When the boom hinge pins switch is
released, the valve returns to the center position. The Node-
3 controller sends a variable 0 to 24 volt output to disable the
accessory system proportional relief solenoid HS-68.
When the boom hinge pins switch is placed in the
disengage position and held, an input voltage is sent to the
Node-1 controller. The Node-4 controller sends a 24 volt
output to enable the boom hinge pins solenoid HS-53 and
shifts the valve to the disengage position. The Node-3
controller sends a variable 0 to 24 volt output to enable the
accessory system proportional relief solenoid HS-68.
Hydraulic fluid pressure at approximately 204 bar (2,959 psi)
flows to the boom hinge pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters piston end of the
boom pin cylinder, extending the cylinder rod to disengage
the boom hinge pins. Hydraulic fluid from the rod end of the
boom pin cylinder leaves the accessory system valve and
returns to the tank. When the boom hinge pins switch is
released, the valve returns to the center position.
Front or Rear Rotating Bed Pins
See Figure 1-35, and Figure 1-36.
During normal operation the rotating bed pins solenoid valve
is motor spooled where both cylinder ports and the tank
port of the valve spool section are connected in the center
position. When an accessory valve spool shifts, the supply
flow to the other accessory valve is limited. The accessory
system pressure sender monitors the accessory system
pressure.
Power is available to the hand-held wireless remote control
when the setup remote mode is selected, the engine is
running, and the power button is pressed. The rotating bed
pins cannot be engaged/disengaged until the keeper plates
are removed from pins.
