The Trencor T1060 mechanical drive chain trencher uses a 350-hp Caterpillar C-9 Tier III engine to transmit power to the digging chain via an Allison three-speed transmission, allowing maximum torque in each trenching speed. A Windows-based load control system regulates trencher and track speeds to maintain performance and reduce engine stalls and machine wear. The high-volume (200 gal.) hydraulic system only operates the tracks, conveyor and boom lift to keep pumps and motors cooler. The unit features a rugged unibody tractor frame, an extra-long, welded, heavy-duty undercarriage that sits within an 8-ft., 2-in. overall width and a narrow profile for transportation without oversize permits.
