 Trench-Tech trencher

Horsepower ratings for the Trench-Tech line range from 275 for the model TT-2000, to 765 for the model TT-2700. Operating weight ranges from about 65,000 to 260,000 pounds. These big machines drive the trencher chain mechanically, via a proprietary four-speed system that, according to Trench-Tech, multiplies the engine's torque output by a factor of two. The TT-2700 shown here uses a Caterpillar 3412E diesel engine and provides boom-length options ranging from 8 to 24 feet. Cutting-width options range from 32 to 60 inches.
