Rock cutting wheels for small trenches in soft and medium hard material
The SMW range is designed for use as an excavator slot cutting attachment. It can cut narrow trenches, especially for laying cables, quickly and efficiently. The reinforced mounting for the cutter wheel provides the strength required for cutting depths down to 1,000 millimeters.
When starting the cut, the weight of the attachment is supported by the sumping bracket and the wheel is gradually pressed down to the required depth. When the required depth has been reached, the wheel is then pulled along the cutting direction either by movement of the excavator arm or by driving the excavator slowly backwards. The cut material is guided out to the side of the trench.
- Specially designed wheel for slots and narrow trenches to a depth of 1,000 millimeters
- High torque hydraulic motor
- High performance cutter wheel with optimum pick pattern
- Cutter wheel mounted on extra strong bearings
- Robust fastening of cutter wheel
- Housing with integrated guide to send cut material to the side of the trench
- Trench cleaner
- Can be used underwater to depths of 30 meters

Cutter wheels can be supplied with different picks to suit various applications and KEMROC have a range of picks available to suit. The weight of the cutter wheel depends on the diameter which determines the maximum cutting depth. The width of the cutter wheel does not have a major impact on the weight of the attachment. Quotations for wheels for different cutting depths can be supplied on request.
