To help power and fibre-optic cable contractors reliably and efficiently use microtrenching for cable installation, Ditch Witch® has introduced theMT26 microtrencher. The attachment is part of a complete microtrenching system, along with the Ditch Witch RT80 ride-on trencher and HX75 vacuum excavator. With the MT26, operators can create a clean, deep, narrow trench in one easy pass, and easily install cable deep enough to meet most requirements with minimal disruption to the surrounding infrastructure.
Designed with a standard hydraulic plunge to provide variable depth control, the MT26 can cut a clean trench from 1½ in up to 3 in (38 mm to 76 mm) wide and down to 26 in (660 mm) deep. Reaching to this depth allows contractors to install a typical 2 in (50 mm) fibre or power cable line with the US requirement of 2 ft (0.6 m) of ground cover all at the same time. In the past, cutting a narrow trench at this depth required a rock saw, which would leave a more invasive trench as well as leave spoils and dirt on the road, or a horizontal directional drill, which would need more time to set up.
Additionally, the ability to create a trench up to 3 in (76 mm) wide, a wider cut it is claimed than any other microtrencher on the market, helps simplify the trench cleaning process for operators, especially when installing at deeper depths. The MT26 does this by vacuum excavating the spoils from microtrencher simultaneously as the microtrencher cuts along the road. This alleviates time and costs associated with jobsite clean-up and restoration, and it opens the door for contractors to take on jobs in markets beyond power and fibre optic installation.
“Microtrenching is quickly growing in popularity among power and fibre-optic installation contractors because it is the least invasive open-cut solution.” said Steve Seabolt, product marketing manager, Ditch Witch HD tractors. “The MT26 is designed to help operators create narrow trenches that go deeper and wider than ever before, which increases productivity and reduces their jobsite cost-per-unit length.”
Operator flexibility is also a key feature of the MT26. The attachment can be equipped with a variety of blades, including the standard carbide-tipped blades and the Ditch Witch exclusive PDC blades with diamond-embedded carbide. All blades are easily changeable with standard hand tools to keep operators on the job, not on the side-lines. The MT26 is also compatible with 4, 5 and 6 in (100, 127 and 150 mm) vacuum excavator hoses, giving contractors the flexibility to use their preferred vacuum excavator.
The MT26 is the latest addition to the Ditch Witch family of microtrenchers, which includes the MT9, MT12 and MT16.
