RT530E-2 OPERATOR'S MANUAL
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 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
• Working Range Limiter
• 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.
Working Range Limiter 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 both a visual and an audible warning if the boom
approaches a virtual wall.
The RCL Setup Screen appears on the RCL Display (upper
screen) when the key is turned on. The operator can select
the rigging first, or go directly into the setup wizard.

OPERATING CONTROLS AND PROCEDURES
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.
Mode of Operation
The rigging options on this screen enable the operator to
select static rubber, pick and carry or outrigger configuration.
The Outrigger Operation Menu is navigated on the lower
CCS Screen.
To choose one of the outriggers' proper positions, fully
retracted, mid-extend or fully extended.
