Drum cutter attachment for excavatoris an engineering equipment that cuts hard materials such as rocks and concrete by rotating the cutter disc. It can be quickly installed at the end of the excavator arm. Its core component is the Excavator Drum Cutter, which drives the cutter disc to rotate at high speed through hydraulics to achieve non-explosive precision excavation. Compared with traditional breakers, this type of equipment has low vibration and low noise and is particularly suitable for densely populated urban areas or sensitive geological environments.

Where are excavator drum cutters widely used?
- Tunnel Engineering: Used for contour trimming of subway and highway tunnels, the Hydraulic Drum Cutter has an accuracy of ±5mm;
- Municipal Renovation: Demolition of old building foundations to avoid damage to surrounding structures caused by blasting vibrations;
- Mining: Cutting of hard rock layers in open-pit mines, replacing blasting to improve safety;
- Pipeline Laying: Trenchless underground trench excavation, Rotary Drum Cutters are suitable for mixed strata of clay and sandstone.
Working principle of hydraulic drum cutter
- Power transmission: The hydraulic system of the excavator drives the hydraulic motor of the Excavator Drum Cutter to rotate the cutter disc;
- Cutting operation: The alloy teeth on the cutter disc cut into the rock formation at a speed of 10-30rpm, crushing the material through axial pressure;
- Debris handling: During the rotation process, the debris is automatically discharged to both sides to keep the working surface clean;
- Intelligent control: Some Rotary Drum Cutters are equipped with pressure sensors to automatically adjust the speed to prevent overload.
