Cutter wheels in the dmw range were designed in cooperation with customers for attachment to hydraulic excavators. Two high torque, lateral hydraulic motors garuantee high production rates and maximum cutting forces. As a result, even in hard rock with a uniaxial compressive strength of 120mpa as well as reenforced concrete, very high productivity rates can be achieved.
DPAIR produces these robust attachments in 4 sizes for excavators from 14 to 60 tons. To meet the demands of many applications, DPAIR have developed cutter wheel variations for cutting depths to 1,000 millimeters. A choice of wheels with different tooling configurations and a range of widths up to 400 mm are available. Wheels with non-standard width and cutting depth are available on demand.
