The Hirschmann HC2900 Load Moment Limiter is a core safety protection device specially designed for tower cranes. It collects and analyzes critical operating parameters—such as load moment, lifting weight, and working range—in real time. When values approach or exceed safe thresholds, it immediately triggers audible and visual alarms, and outputs control signals to force the equipment to stop dangerous actions.
