For excavators with weight from 3 to 50 tons.

Longitudinal drum cutters are driven by a powerful radial piston motor creating extremely high cutting forces. The robust cutter drums together with their secure fixing method enable them to operate in the most demanding conditions. Consoles can be supplied with different lengths to suit a variety of applications.

Typical applications for Erkat longitudinal drum cutters include trenching, accurate excavation of irregular shaped foundations, slag removal in steel mills, cleaning pile heads and soil mixing. Erkat longitudinal drum cutters are designed to be mounted on excavators from 3 to 50 tons and are available in 9 different sizes.

By exchanging the cutter head, the Erkat longitudinal cutter can be easily converted into a powerful ADU auger drive unit for vertical and horizontal holes.

  • Robust, high torque drive
  • Different length consoles available
  • Secure, strong cutter drum fixture
  • Oversized, long-lasting cutter drum bearings
  • Robust long-lasting cutter drums
