System Description
EA Heigh provides a Rated Capacity Indicator (RCI), Height Limiting, Cab Protection, Dig Depth Monitoring and a Transpor-
tation mode for use on monoboom and triple articulated machines.
The system will allow the use of telescopic sections along with secondary booms and arms giving real time height measurements
with automatic/ manual duty switching.
A keyswitch is supplied allowing quick access to functions along with locking the system into certain modes.
Motion control is standard on the EA Heigh allowing motion to be cut to the boom, artic and arm for Height Limiting and Cab
Protection.

RCI
EA Heigh RCI mode displays the current maximum
safe working load (SWL) in tonnes. In RCI mode, the top line
of the display shows the current bucket pin radius and the
maximum safe working load at that radius. The bar graph on
the lower line will indicate the proximity of the current load to
the maximum available safe working load. The system
indicates an approach to overload and an overload condition
via internal and external alarms along with visual indicators on
the display.
To calculate the SWL, the radius of the bucket pin (Or Lifting
point) and the pressure within the boom lifting rams are used.
