What does the Rated Capacity Indicator do?

The Rated Capacity Indicator (RCI) is a critical safety feature of tower cranes, designed to monitor the actual load being lifted in real-time. Its primary function is to prevent overloading the crane by continuously assessing the weight of the load in relation to the crane's rated capacity. If the RCI detects that the load exceeds the crane's safe operating limits, it will typically trigger alarms or alerts, and may even limit certain crane functions, thereby ensuring the safety of both the crane and personnel in the vicinity.

By actively monitoring the load, the RCI plays a vital role in preventing accidents and structural failures that could arise from overloading, making it an essential component of safe crane operation.
