Features High displacement motors with high torque for extra productivity and cutting force. Gear box manufactured from thicker steel plate. Stronger output shaft fixing to the gear box housing. Thicker wear plates.

The Productivity Table in the downloads below is an indicator of the productivity rates that can be achieved within the operating range of rock hardness suitable for rotary drum cutters Size of hydraulic motor. Cutting direction (wall, floor, trench, etc). Operator experience. Ground conditions e.g. layers, fissures, weathering, etc.

Power is needed to fracture materials such as concrete or rock. As the compressive strength of the material increases, more power is needed to fracture it. The available power of the drum cutter is limited by the hydraulic motor and the available power of the excavator. As drum cutters increase in size, they have larger hydraulic motors, draw more power from the excavator, and are able to cut harder rock. Please see the Compressive Strength Chart for Common Rock Types in the box below to see the operating limits for each size of drum cutter. This table is intended as a guide and under certain conditions these limits may vary.

It is important to match the correct size rock cutter with the excavator. The rock cutter must be strong enough to support the weight of the shovel and the shovel must be strong enough to take up the energy transmitted to the machine by the drum cutter. The weight of the rock cutter must not destabilize the shovel. Rock cutters get their power from hydraulic flow and pressure from the excavator. The best cutting performance is achieved when the drum cutter's hydraulic motor matches the hydraulic output of the excavator's pumps.

Drum cutter attachments for excavator can be used for rock excavation, demolition, underground scaling, tunnel profiling, trenching and other applications.

Drum cutter attachments for excavators can also be used underwater without modification at depths of up to 30m.

Rotary drum cutters or rock cutters are hydraulic excavator attachments. Designed to increase the range of work available to excavators and increase their return on investment. Tunnelling. Trenching. Demolition.

A drum cutter is an attachment where rotating drums equipped with picks, strategically positioned around the outer diameter, are rotated by a hydraulic motor at several hundred revolutions per minute to cut rock, concrete or frozen ground.
