Disc Brake Operational Test
There is no physical way to check the disc brakes for travel,
boom hoist, load drums, and swing. Therefore, an
operational test of each brake must be performed weekly.
Figure 2-12
shows the brake and brake solenoid valve
locations.
NOTE: See Table 2-10
for system pressure specifications.
The electrical connectors must be disconnected at
the brake solenoid valves to stall the crane
functions during the test.
To test the disc brakes, use the following procedure:
1. Disconnect the electrical connector for the brake being
checked.
2. Start the engine and run at low idle (850 to 950 RPM).
3. Select the corresponding Liftcrane Boom Capacity Chart
on the RCL screen.
4. Turn off the park switch on the control console for the
function being checked.
5. Access the diagnostic screen (Figure 2-24
) for the
function being checked – Drum, Boom Hoist, Swing, or
Travel.
Monitor the system pressure and the pump command
while moving the control handle.
6. Slowly move the control handle for the function being
checked. The specified system pressure must be
reached before 50% pump command is reached and the
brake must not slip.
7. Repeat steps 3 through 6 for each function.
8. Reconnect the electrical connector to all the brake
solenoid valves at the completion of the operational test.
9. If disc brakes were repaired or replaced, retest the
brakes before operating with a load.
Cab Tilt Adjustment
To adjust the speed at which the cab tilts up and down,
proceed as follows.
See Figure 2-31
for the following procedure:
1. Loosen the set screws.
2. Turn the knobs fully clockwise to close the valves.
3. Open both valves slightly.
4. Test the cab tilt operation with the switch on the control
console in the cab.
5. Repeat steps until the cab tilt starts and stops smoothly
in both directions.
6. Securely tighten the set screws.
CAUTION
Overheating Hazard!
Do not hold any function on stall for more than 5 seconds.
Damage from overheating can occur to system
components.
WARNING
Falling Load/Moving Crane Hazard!
If a disc brake slips when the operational test is
performed, repair or replace it before placing the crane
back into service. Loads could fall or the crane could
move if the brakes are not operating properly.
See the gear box manufacturer’s manual for the disc
brake repair instructions.
