ST2 trencher for mechanical laying

ST2, a wheel trencher of the Marais line, allows simultaneous trenching and mechanical laying for the deployment of networks (telecoms, electricity, drainage, water, sanitation, gas, etc.) in rural environments and in rocky grounds. ST2 trenching wheel allows to cut up to 155 cm deep, guarantees high accuracy, productivity and a reliable costs monitoring. This model can be adapted to different grounds condition, assuring the best performance in all the situation.

Benefits

Simultaneous performance of the trenches and mechanical laying for the deployment of the networks

  • Network laying quality, constant depth, constant altimetry and planimetry of the laid network
  • Quality of the trench bottom thanks to the shoe, smooth clean and compact trench bottom without any salient angle
  • Non-stop shielding of the cut trench thanks to the laying unit
  • Preservation of the geometric data of the cut trench
  • Compliance with the bending radius of the cables and the ducts
  • Vertical cutting on an inclined ground allowed thanks to the frame slope correction

Constant and reduced width of the trench, constant building cost per meter

  • Machine data remote monitoring
  • Fleet location management
  • Troubleshooting & operating conditions information

*information available according to machine configuration

  • As built data logger
  • Avoid stakeout resulting in time and cost reduction
  • Project proof upon completion
