Work area definition

TWG’s Work Area Definition (WAD) sensor is an optional addition to a planetary gear drive for a crane, designed as an operational aid to keep you working in a safe zone. The WAD reduces the threat from hazards common on every job site.

Only two models are shown, but we offer custom engineered options as well.

  • Greer Work Area Definition WAD Sensor, on top of a planetary gear or swing drive, on a white background


  • Integrated into a planetary gear drive
  • Limits rotation to avoid hazards
  • Fully integrated into the LMI system
