Leaders in drum cutting technology

We have over 25 years experience in the development, manufacture and application of rock cutting excavator attachments.

With the main components manufactured in Germany, Erkat special cutter attachments for excavators and skid-steer loaders are robust and reliable.

Machines from Erkat offer a great alternative for those applications where more traditional methods are either inadequate or too expensive.

Transverse drum cutters

Transverse Drum Cutters are an excellent choice for rock or concrete wall and surface profiling, trenching, soft rock and frozen soil excavation and demolition.

Axial drum cutters

Axial Drum Cutters are designed for narrow trenching, pile head removal and gutter cleaning.

Application overview

Drum Cutter ER 2000 on a 48t Hitachi excavator. Digging trenches. Granite

Trenching

Drum cutter ER 600-1 on a CAT 314 excavator. Wine cellar excavation. Sandstone

Tunneling

Drum cutter ER 3000 on a Hitachi ZX 470 excavator. Quarrying limestone

Quarrying, mining

Drum cutter ER 1500-3 X on a Volvo EC 360 excavator. Digging drainage trenches Average production rate per hour in hard limestone: 11 m³

Excavation work

Penetrating walls. For the installation of an additional turbine for the pumped storage power plant at the Wendefurth dam in the Harz Mountains, a breakthrough in the lock wall must be created. A task that is accomplished by an ER 600 with flying colours

Refurbishment

Demolition of a bunker. When dismantling an old high-rise bunker in Hamburg, two ER 1500 XL series milling machines are working their way from top to bottom, milling the up to 3.5 m thick concrete slabs and walls from the inside out completely without difficulty. In the process, parts of the outer walls are left standing to protect them from noise, dust and possible rockfall, and are only demolished at the end of the operation. Demolition work Volume: approx. 8,000 m³ reinforced concrete (reinforcement diameter up to 20 mm) Duration: 6 months Milling performance per hour and machine: 4-5 m³ Chisel consumption ER 22/75/70/30 Q: approx. 60 pieces per 100 m³

Demolition

Road construction

ER 400-2 L drum cutter on a Liebherr A 316 excavator. Exposing pile heads

Pile head cutting

ADU 1500 on a Liebherr R 926. Before sheet piles can be installed, an ADU 1500 loosens ground consisting of sand, gravel, clay and small boulders with an auger and pilot bit designed for use in rock. Loosening the ground prior to installation, reduced vibration levels that could have damaged buildings located nearby. Length of auger: 9 m (one piece) Auger diameter: 500 mm Pilot bit type: SFBC R3HD Drilling speed: 1.2 – 1.5 m/min

Auger drilling

ER 250 W on a Mecalac 12 MXT. Tree stump removal

Wood grinding

ER 1500-1 XL on a Daewoo S 280. An ER 1500 XL being used to deepen a harbour in Batam, Indonesia in preparation for the larger oil tankers planned for the future. The drum cutter is working at depths of up to 13 metres under water. Erkat rotary drum cutters can be used up to 30 metres under water without the need for any modifications.
