HT Pro (PME100)

-height monitor/limiter




  • Height Control
  • Envelope Control

Suitable for

  • Excavator (multiple articulations)
  • Telehandler
  • Mobile Carnes (EN13000:2010)
  • Truck mounted cranes
  • Backhoes (both front and rear equipment)
  • Forklifts

PME100 is designed for monitoring and controlling the movement of any articulating equipment. The system measures position via the use of sensors to guide the operator to stay within a user defined working envelope. The basic system monitors vertical height with a 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. The operator will benefit from Prolec’s easy to use ‘Man Machine Interface’ MMI integrated within the foundation of PME.
