Shift on the fly to trench in varying materials
Tesmec USA’s 1175XHD has a three-speed digging system. The hydraulic machine allows you to maintain high productivity in varying materials by having the ability to trench at the slowest full-power digging attachment speed and then shift on the fly to the highest digging attachment speeds. Configured with the company’s Chainsaw Module, the machine can trench up to 42-inch widths and 12-foot depths in hard rock. The unit’s Bucket Module can trench up to 54-inch widths and 9-foot depths.
Trench up to 60 inches deep, 12 inches wide
The rubber-track undercarriage of the new Vermeer RTX450 ride-on trencher offers lower ground pressure and increased traction compared to rubber-tired units. Other advantages of tracks include less ground disturbance, additional surface contact, better flotation in soft soils and greater side hill stability. The trencher, powered by a 46.3-horsepower Deutz diesel engine, can trench depths to 60 inches and up to 12 inches in trench width. Other features include an enclosed spring-applied hydraulic release park brake, a 58-inch track base and cutters supported by bolts through both side plates of the trencher chain assembly. The standard front attachment is a six-way backfill blade. Optional rear attachments include a high headshaft center-mounted trencher or a hydraulic sliding offset trencher.
Trencher offers steel or rubber tracks
Ditch Witch’s HT115 track-mounted trencher offers the ability to perform in wet, boggy conditions. Featuring rubber or steel tracks, the machine also has a heavy front-end weight for easy plowing, a 45-gallon fuel tank and an improved cooling system. The steel tracks perform best in areas that require a great deal of traction, while the rubber tracks efficiently navigate urban jobsites. Trencher speed and direction is controlled by a single joystick, and the machine has AutoTrack, a computer-controlled track drive system that regulates speed while the attachment is operated, helping reduce operator fatigue. Both the HT115 and the RT115 tire-mounted trencher have 115-horsepower John Deere engines.
Mechanical drives offer high torque, reduced wear
The Trench-Tech Series 2000 chain trenchers are mechanically driven, and according to the company, provide the ability to deliver twice the torque of hydrostatic trenchers, reduce wear on cutting teeth and use less fuel to operate. The power train generates increased digging power when trenching hard rock, thus increasing digging speed. The mechanical drive enables the chain to dig slower using first gear, a tactic that breaks up material better and puts less wear on the teeth. Four different chain speeds provide high torque for all digging conditions. The 2000 Series has four models, including TT-2000C, TT-2200C, TT-2500C and TT-2700C, ranging in horsepower from 275 to 765.
Shift on the go with maneuverable trenching package
Astec’s RT 960 trencher, powered by a 99.5-horsepower diesel engine, provides a maneuverable, easy-to-operate trenching package. The four-speed, shift-on-the-go Hydrashift transmission makes gear changes quick and easy. The transmission also enhances creep control for applications that demand precise control. Coupled with the Hydrashift is a hydrostatic system that provides infinite variable speeds. The bent-axis ground-drive motor supplies tractive power in the toughest ground conditions. The RT 960 can power a quad configuration or a combination of attachments, such as a vibratory cable plow, backfill blades, backhoes, real carriers, rock wheels and the Astec Hydra-Borer boring unit.
