This cable reel sensor is a core safety component in construction machinery, designed specifically for mobile cranes and all-terrain cranes. It integrates high-precision sensors and an automatic cable retraction mechanism to simultaneously detect boom extension length and elevation angle, transmitting real-time data to the Load Moment Indicator (LMI). This eliminates overload risks at the source, making it a critical device for ensuring lifting safety.
