The Robway RCI-4100IS is an Intrinsically Safe Rated Capacity Indicator specifically designed for cranes

operating in hazardous areas.


The RCI-4100IS provides the crane operator with an in-cabin alphanumeric and numeric LCD display of the hook loads, safe working loads (SWL curves), boom length, boom angle, radius, hoist rope falls, duty (sea-states), local time & date, and boom tip height. Other operational data such as AGOP/GOP activation, wind speed, boom slew position, and hook position are also provided on the display when these optional devices

are supplied with the system.




Robway is quality endorsed to ISO 9001:2000 with many international certifications.

Simplified calibration & fault-finding techniques have been developed by Robway to minimize down-time.

The RCI-4100IS can be supplied with historical data logging of crane usage and/or overload history which can be used forpredictive maintenance.

Designed for hazardous area application and complies with IECEx Class 1, Zone 1 and ATEX Class 1, Zone 1 Standards.

The RCI-4100IS can be supplied with restricted slew zone to warn the operator of impending collisions with jack-up legs or other obstacles on offshore drilling rigs or restrict travel of loads over hazardous areas. Multiple restricted zones can be set.

Automatic Gross Over-moment Protection (AGOP) or manual Gross Over-moment Protection (GOP) system can be integrated into the RCI-4100IS to suit application.

Tare facility included in the standard system.

Operator-selectable sea-states/duties.

Multiple relay outputs for activating AGOP/GOP device and external alarms, also for inhibiting hoist, luff, and slew motions.

Analogue outputs for specialized applications.

Robway provides comprehensive product training in-house.

PWM (Pulse width modulated) output facility to speed control or decelerate various functions.
