PME 100 – Height and 2D Envelope Monitor

PME100 is designed for monitoring and controlling the movement of any articulating construction equipment. The system measures position through sensors to guide the operator to stay within a user defined working envelope. The basic system monitors vertical height with an fully featured variant available monitoring the machine’s vertical 2D envelope (height, reach, cab protection and depth), fully describing the machine’s working envelope. Optional control on hydraulic motion can be installed to automatically override movement on reaching user-set limits.

Suitable for:

  • Excavator (multiple articulations possible)
  • Telehandler
  • Mobile cranes (to EN13000:2010)
  • Truck mounted cranes
  • Backhoes (forward and rear buckets possible)
  • Forklifts
  • Special purpose machines
