Terex Corp., Southaven, Miss., has introduced seven hydraulic transverse cutting units to the North American market. Featuring transmissions with patented gear reduction technology, these attachments are designed for use with the Terex family of excavators (models ranging from 4,400 pounds to 132,000 pounds) and with Terex tractor loader backhoes for excavation, scaling and demolition work. Terex hydraulic cutting units are ideal for trenching in pipeline construction; building renovation; demolition; road construction; landscaping; tree removal; scaling, profiling; and underwater and dredging applications. The Terex cutting unit range is comprised of seven models — WS15, WS30, WS45N, WS60N, WS90N, WS120N and WS150N — all designed with heavy-duty spur gears and bearings, powered by a low-speed, high-torque hydraulic drive motor ranging from 24 horsepower to 190 horsepower and a hydraulic flow ranging from 8 gpm to 158 gpm. The transmissions of Terex hydraulic transverse cutting units feature patented gear reduction that boost cutting power, according to the company. All seven models offer a choice of hydraulic motors, ensuring a flexible adjustment to individual carrier and operating conditions. Three standard cutting heads are available for use with Terex cutting attachments: excavation, scaling and demolition. The excavation drum is best suited for soft to medium-hard rock; the scaling drum is designed for applications in soft to medium-hard rock where a precise or smooth surface is required; and the demolition drum works best in medium-hard to hard rock and concrete.
