The minitrencher with remote control is currently
the faster and performing equipment for the installation of fiber optic systems


The remote controlled minitrencher curves along the road and speeds up the installation


Thanks to minitrencher and ground penetrating radar handled by qualified personnel,
we significantly reduce installation times, costs and inconvenience to road traffic

With the minitrencher on 100 meters excavation you can save:
80% of excavation and fiber optic installation time
40% of personnel needed
55% of total working cost


It performs an excavation of limited depth and width, ideal for laying the optical fiber.
The operator guides it from the ground with a radio control, enjoying the best possible view


The minitrencher is the most convenient method to install infrastructures


We offer quality thanks to our multidisciplinary know-how,
also specialized in project management, design and turnkey optical fiber solutions

We have our own vehicles and equipment and 32 construction technicians qualified for street works and road signs, confined spaces, work at height and driving of operating vehicles.

Ground penetrating radar

Special workings

Before each excavation, we perform the investigation with the ground penetrating radar to prevent damage to existing plants during the subsequent excavation phases.

Fiber optic for buildings

Wiring buildings in FTTH

Our technical staff is qualified for working at height and allows us to make piling, overhead lines and the cabling of buildings with optical fiber, in compliance with all safety regulations.
