Extending the Boom (Dual Axis Controller Option)
To extend the boom, push the controller on the left hand
armrest forward and hold until the boom reaches the desired
length.
Retracting the Boom (Dual Axis Controller Option)
To retract the boom, pull the controller on the left armrest
back and hold until the boom retracts to the desired position.
Extending and Retracting the Boom With the
Telescope Control Pedal (Dual Axis Controller
Option)
The telescope control pedal is used on a crane equipped
with an auxiliary hoist. Push on the top of the pedal to extend
the boom and push on the bottom of the pedal to retract the
boom.
Lowering And Raising The Hoist Cable (Dual Axis
Controller Option)
NOTE: When the load is stopped at the desired height, the
automatic brake will engage and hold the load as
long as the control lever remains in neutral.
Lowering The Cable
Push the control lever forward to MAIN HOIST DOWN or
AUX HOIST DOWN, away from yourself, and hold until the
hook or load is lowered to the desired height.
Raising The Cable
Pull the control lever back to MAIN HOIST UP or AUX
HOIST UP, toward yourself, and hold until the hook or load is
raised to the desired height.
Hoist Speed Range Selection (Dual Axis Controller
Option)
To change the speed range of the hoist(s), position the
applicable switch (MAIN HOIST SPEED or optional AUX
HOIST SPEED) to HIGH or LOW as applicable.
Operational Aids
Rated Capacity Limiter (RCL) System
The Rated Capacity Limiter (RCL) is an electro-mechanical
sensing system designed to alert the crane operator of
impending capacity when the system has been properly
preset by the operator. The control panel is mounted in the
dashboard of the operator’s cab. When an overload
condition is sensed, the system provides the operator with a
visual and audible warning, and locks out the control levers
to prevent lowering the boom, extending the boom, or raising
the main or auxiliary hoist cables.
RCL Boom Alarm (CE Units)
In addition to the audible warning in the cab, an audible RCL
boom alarm is also mounted in the vicinity of the boom flood
lights to warn all personnel that a lockout has occurred.
Three additional features are included within the RCL
system:
WARNING
When extending the boom, simultaneously let out the
hoist cable to prevent two-blocking the boom nose and
hook block.
DANGER
Check the load chart for the maximum load at a given
radius, boom angle, and length before extending the
boom with a load.
CAUTION
Before extending the boom, ensure the large access
cover on top of the boom base section is installed.
WARNING
When retracting the boom, the load will lower unless the
hoist cable is taken in at the same time
WARNING
Keep the area beneath the load clear of all obstructions
and personnel when lowering or raising the cable (load).
Do not jerk the control lever when starting or stopping the
hoist. Jerking the lever causes the load to bounce, which
could result in possible damage to the crane.
CAUTION
Do not change the hoist speed range with the hoist
rotating.
DANGER
Electronic equipment on this crane is intended as an aid
to the operator. Under no condition should it be relied
upon to replace the use of capacity charts and operating
instructions. sole reliance upon these electronic aids in
place of good operating practices can cause an accident.
