Longitudinal drum cutters

Specifically designed for narrow trench work, the excavation of irregular shaped holes and cleaning material from ladles and runners.

Standard transverse rotary drum cutters are not suitable for the excavation of very narrow trenches. Longitudinal drum cutters were designed to meet this need. The ER 250 L or ER 400 L can cut a trench as narrow as 400mm wide.

The same limitations regarding excavator weight and rock hardness apply to longitudinal as to the standard transverse rotary drum cutters.

Due to its unique design, people have found other applications where the longitudinal drum cutter can be used. These include:

  • excavations with complicated shapes e.g. foundations for electricity pylons and windmill electricity generators, connecting trenches produced with larger trenching machines
  • cleaning slag from ladles and runners in steel mills where care must be taken to limit damage to expensive refractory linings
  • auger drilling when used with an adaptor

Longitudinal drum cutters are limited in the depth they can go down to. This is normally limited to the length of the drum cutter housing, the space available in the excavation to manouvre the drum cutter and ability to extract cuttings from the excavation.

Longitudinal drum cutters can be supplied with an adaptor that allows them to be used as an auger drive unit. The cutter drum needs to be removed to attach the adaptor and augers.
