Trenching with a single tool

We have been providing trenching equipment for over 20 years to support your cable protection requirements. The combi-tool℗ systems combine jetting and chain cutting technology to incorporate the latest technology.  The ability to cover trenching of a wide range of materials from soft mud to rock with a single tool allows for continuous trenching without tooling transitions.

Power and efficiency

Since the combi-tool seamlessly transfers between cutting modes the overlap of tool choice is no longer required. The jetter needs only to cope with 75kpa soil and not 150kpa soil which has a marked effect on the power required to be installed on the vehicle. 

The chain cutter does not need to cope with anything less than 75kpa clay and hence the pick and transportation paddles can be configured appropriately.

Since the combi-tool can trench in the full range of soils the only consideration is that of vehicle bearing capacity, in very weak soil conditions additional buoyancy may be required.
