i4507 Rated Capacity Indicator RCI

For lattice boom cranes

The i4507 (7” display) RCI on lattice cranes uses a variety of sensors depending on what will work best on the specific model crane. Often the system will use two dynamometers or a dynamometer and dead-end load link along with the boom angle sensor and ATB switch assembly. Cranes with luffing jibs will add a 2nd angle sensor and some cranes will use a slew sensor to measure 360 degree rotation. Other optional sensors include list angle sensors for cranes on barges or windspeed sensors mounted at the boom tip. For large lattice cranes the RCI system is the most important operator aid for the safety and efficiency.
