The i4507 (7” display) RCI on the lattice and fixed boom offshore cranes use a variety of sensors depending on what will work best on the specific model crane. The common sensors are dead-end load links, dynamometers, angles sensors, and ATB switch assemblies. All the sensors came in a marine duty version, usually stainless steel. I4507 systems are also available for cranes in hazardous gas areas or class 1 div 2 zones for the boom or cab. RCI systems on offshore platform cranes are critical to the safety and efficiency of the vessel and a required operator aid in most cases.
