OPERATING CONTROLS AND PROCEDURES RT765E-2 OPERATOR MANUAL
3-40 Published 4-09-2021, Control # 364-11
NOTE: The telescope function is controlled by a foot pedal
if the crane is equipped with an auxiliary hoist.
To extend the boom, push on the top of the Telescope
Control foot pedal.
Retracting the Boom
To retract the boom, push on the bottom of the Telescope
Control Foot Pedal.
Lowering and Raising the Hoist Cable
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 Main or Aux hoist control lever forward, away from
the operator, and hold until the hook or load is lowered to the
desired height.
Raising the Cable
Pull the Main or Aux hoist control lever back, toward the
operator, and hold until the hook or load is raised to the
desired height.
Hoist Speed Range Selection
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
front console 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.
Three additional features are included within the RCL
system:
• Swing Angle Set Limitation
• Work Area Definition
• Anti-two Block Device
Swing Angle Set Limitation allows left and right swing
angle to be preset. When the preset angle is reached, the
system will provide an audible warning.
Work Area Definition allows the crane operator to describe
the crane’s working area by setting up “virtual walls”. They
are referred to as virtual walls because they exist in the
system and are not real walls. The virtual walls represent
obstacles (i.e. buildings, towers, poles, etc.) in the crane’s
working range. They are set by defining points along the
outer limits of the working area with the tip of the boom. Once
the working area has been defined, the system will provide a
visual and an audible warning if the boom approaches a
virtual wall.
CAUTION
Machine Damage!
Before extending the boom, ensure the large access
cover on top of the boom base section is installed.
When extending the boom, simultaneously let out the
hoist cable to prevent two-blocking the boom nose and
hook block.
DANGER
Crushing Hazard!
When retracting the boom, the load will lower unless the
hoist cable is taken in at the same time
DANGER
Crushing Hazard!
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
Equipment Damage!
Do not change the hoist speed range with the hoist
rotating.
WARNING
Unexpected Operation Hazard!
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.
