Offset Wheel Trencher for the mechanical laying of networks

Process Tangentially driven trenching wheel designed by Marais

Specific Features Cutting outside the overall sizes of the machine : with mass transfer on opposite track : 350 mm

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

Non-stop shielding of the cut trench : the laying unit, Preservation of the geometric data of the cut trench, Compliance with the bending radius of the cables and the ducts.

Quality of the trench bottom : the shoe. Smooth clean and compact trench bottom without any salient angle.

Network laying quality.Constant depth, Constant altimetry and planimetry of the laid network.

Assets Cutting of different grounds

Cutting configuration along roads in ditch bottom, behind safety barriers or along railways. Compliance with the bending radius of the cables and the ducts

Reduction in building costs

Innovations Driving seat platform mouted on the machine

Radio remote control

Central greasing

Low center of gravity

Output From 300 to 2,000 lm/day depending on the grounds,sections of trenches and nature of the network to be laid

Simultaneaous performance of trenches andmechanical laying for the deployment of networks(telecom, electricity, drainage, water, sanitation,gas, etc…)
