Cutting Techniques of the Auger Torque Drum Cutter Attachment

Want to know the most effective way to use your Drum Cutter?

Take a read below from a selection of excerpts from our Drum Cutter Operators Manual with instructions on how to best use the attachment in different cutting scenarios.

The Auger Torque Hydraulic Transverse Cutting Unit (“TCU”; “cutting unit”) is suitable for mounting on any type of hydraulic excavator provided the attachment carrier can supply the required power and machine stability is always ensured. It is mounted to the excavator dipperstick either through direct attachment or using a quick-attach system. Their power makes Auger Torque cutting units flexible for a wide range of applications. The cutting units are designed to cut most types of rock, brickwork, concrete and asphalt etc. The Auger Torque cutting unit can run at full system pressure. This means there is no need to adjust the secondary pressure lower than the system pressure, thus avoiding overheating of the hydraulic circuit.

Although generally less noisy than other excavation methods the user must take into consideration the standards for noise protection during operation and carry out a noise measurement if required. Appropriate protective measures must be taken. In order to ensure functionality and the safe operation of the equipment, we recommend you handle it properly and regularly perform maintenance and inspection tasks. Improper handling will result not only in problems with the unit, but will also negatively affect operating performance.

Cutting operations are best if the cutting unit drum moves into the direction of the attachment carrier. If the unit is moved sideways to achieve a larger cutting area, it must be ensured that the pressure on the excavator’s boom, arm and cutting drum bearing is not too strong.

Using the Drum Cutter in Ditches

For typical cutting operations in trenches, set the direction of rotation of the attachment cutter head in the direction of the carrier machine.

Using the Drum Cutter on Tarmac

For cutting on tarmac, set the direction of rotation of the cutter head opposite to that of the carrier machine. This prevents larger lumps from breaking out in an uncontrolled manner.

Using the Drum Cutter on Walls

When using the cutter head on vertical surfaces such as walls, we recommend changing the direction of the cutter drum – reverse the cutter head. This reduces vibrations and opposing forces during cutting and prevents the cutting head from “climbing”.

Using the Drum Cutter Underwater

The cutter may only be used in wet areas or in water up to a depth of 20m (66ft) after consultation with the Auger Torque Technical Customer Service and after retrofitting for use in water.
