RCL Check
Perform the following checks to verify proper RCL operation:
• Check that the display of the main boom length agrees
with the actual boom length.
• Check that the display of the main boom angle agrees
with the actual boom angles.
• Check that the display of the operating radius of the
crane agrees with the actual radius.
• Check that the outrigger monitoring system is
functioning at all outrigger positions—retracted, mid-
extend and full extend. Refer to Outrigger Monitoring
System (OMS) (Optional—Standard in North America),
page 4-2.
Check the load display by lifting a load of known weight. The
accuracy of the load indication shall be within the tolerance
of SAE J159.
HOIST SYSTEM OPERATION
The hoist may have lifting capabilities greater than that of the
crane limits. Therefore, care must be taken to ensure that the
load lifted is within the crane rating. General rules for hoist
operation are:
• Unwind the hoist when extending the boom.
• Use the anti-two-block system only as an aid.
• Make sure the rope is not twisted or kinked and that it is
properly seated in the hoist and in sheaves.
• Always have at least three full wraps of rope on the
hoist.
• Check the hoist brake when approaching the load limit of
the hoist. Raise the load a few inches and return the
control to neutral to check the brake.
• Do not drag the load with the hoist.
• Do not try to lift loads that are not free such as, frozen
down material or poles.
• Keep tension on the rope to prevent it from becoming
twisted, kinked, or improperly seated on the hoist.
WORK SITE LOCATION
Select a location that is firm, level, and dry. Avoid uneven,
rocky or muddy terrain, steep grades, or locations with
overhead obstructions. The outrigger stabilizers must be
supported on a firm level surface at the fully retracted,
mid-span, or fully extended positions. Avoid overhead power
lines.
Before Leaving the Truck Cab
• Position the truck so that the outriggers can be extended
with no obstructions.
• Put the truck transmission in neutral.
• Set the truck park brake. Wheel chocks may also be
required.
• Engage the power takeoff.
• Ensure the truck ignition switch is in the ON/RUN
position.
NOTE: PTO engaged and truck ignition in the ON/RUN
position will power up the Crane/RCL system. The
engine does not need to be shut off before moving
from the truck cab to the crane platform.
To operate crane, both truck ignition switch and crane
ignition switch must be ON. If any ignition is OFF, truck
engine will not run and crane will not function.
If the crane is NOT equipped with a radio remote, the
remotes power switch must be OFF.
DANGER
If the RCL does not function as described, the system is
not working properly. The malfunction must be corrected
as soon as possible.
Refer to Operational Aids, page 2-4 should the RCL be
inoperative.
Lifting personnel is not permitted with a malfunctioning
RCL.
DANGER
Tipping Hazard!
If the Outrigger Monitoring System is not functioning, the
operator must confirm the proper deployment of the
outriggers before continuing with the lift.
DANGER
If there is a deviation between displayed and actual
values, an authorized RCL service representative shall be
called for repair and/or recalibration of the RCL system.
WARNING
Truck must be in neutral when starting engine from the
crane platform to avoid sudden potential movement of
truck.
