UNAC's 250SC trencher on caterpillar tracks, depending on the tool selected, can trench through any type of soil up to 1.80m in depth and 500mm in width. With the accessories, the trencher can hold a reel for the mechanical laying of cable, conduit or pipes before closing the trench.


The carrier for the 250SC trencher on caterpillar tracks was custom-manufactured to meet the specific needs that arise with trenching. The mechanically welded chassis with box-section side rails provides high resistance to the vibration and stress imposed by the trench-digging tool. The caterpillar tracks allow the trencher to travel over any terrain, and can be equipped with rubber units for travelling over asphalt.
The driving station is open and protected by a simple mechanically welded structure.
The carrier is equipped with a tool slide interface which allows various tools to be mounted, according to the needs and characteristics of each project.
The 250SC can be delivered with the following tools:

* Rock saw
* Alligator chain
* Vibrating ploughshare

Tools are selected according to the work sites.
The rock saw and Alligator chain models vary in width, according to requirements. The rock saw is made of dual-drive super-strong web for unequalled lifespan and robustness. When trench widths vary from project to project, only the wheel assemblies must be changed. Similarly, for the Alligator chain, only the chain units need to be changed to alter the trench opening width.
