Moment limiter G for Kobelco RK70

The moment limiter, designated as MOMENT LIMITER G, serves as a safety device for cranes and lifting equipment. It continuously monitors the load being lifted and the current operating radius to calculate the real-time load moment. When this value exceeds the pre-established safety limits, the unit triggers visual and audible alarms and restricts crane functions that could lead to instability or structural overload.

This component, part number 2479U1237F1, is compatible with the Kobelco RK70 rough-terrain crane. The system integrates data from various sensors, including load cells on the hoist line, boom angle sensors, and boom length sensors. These inputs are processed against pre-programmed load charts specific to the machine configuration.

A moment limiter functions by comparing live operational data against the manufacturer's load charts. By managing the relationship between load weight and boom reach, the system acts as a primary control to prevent tipping or mechanical failure during lifting tasks. Regular calibration and verification of the sensor inputs and the central processing unit are required to maintain the accuracy of the safety system.
