A core safety monitoring component designed specifically for mid-to-small tonnage truck cranes and crawler cranes. As the “eyes” of the Load Moment Indicator (LMI) system, it accurately captures real-time boom extension length and angle data, then transmits signals stably to the controller. This prevents dangerous conditions like overloading and over-hoisting, ensuring safe lifting operations.
