GRT880 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
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 joysticks to
prevent lowering the boom, extending the boom, or raising
the main or auxiliary hoist cables.
The RCL Setup Screen appears on the RCL Display (upper
screen) when the key is turned on. The operator can select
rigging first, or go directly to the setup wizard.
Mode of Operation
Rigging options on this screen 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.
DANGER
Electronic equipment on this crane is intended as an aid
to the operator. Under no condition should it be relied on
to replace use of capacity charts and operating
instructions. Sole reliance on these electronic aids in
place of good operating practices can cause an accident.
