Chain cutters – Patented cutting attachment; reduces wear & tear on the excavator swing gear and saves energy
Cutter wheels with double motor for rock up to 120 MPa
KEMROC produces these robust attachments in 4 sizes for excavators from 14 to 60 tons. To meet the demands of many applications, KEMROC 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.
The DMW range is designed to work under water to depths of 30 meters, making the cutter wheels ideal for trenching and underwater demolition projects.
- Rigid, manouverable mounting frame
- Two high torque hydraulic motors
- Smooth and regular cutting action
- Cutter wheels for various cutting depths and widths
- High performance due to proven pick types and pattern
- Supports for vibration free cutting
- Optional – water nozzles for dust suppression
- Operational to 30 meters underwater
- Ideally suited for concrete demolition
