Excavator Load Moment Limiter

Performance Monitoring

Monitor load weight, torque and excavator body level in real time to provide operators sufficient information to make timely decisions

Machine Control

Automatic control of the moving excavator to ensure it does not exceed limited torque, sense and monitor obstacles and people around it to prevent collision and only moves within the safe zone

Smart Maintenance

Digitise maintenance schedule and alert relevant personnel when it is due for maintenance or services to minimise machine downtime

Network Communication

It sends sensor data to IoT cloud platform for users or management to conduct more meaningful analysis, further develop advanced analytics capability, or redeploy new algorithm back to the device to continuously improve its functionality

Specification Summary

  • System error: ≤±3%
  • Display error: ≤±3%
  • Operating environment: Temperature: -20~60℃; Humidity:095%RH
