Longitudinal drum cutter - Drumcutters

Keywords: Auger Drilling, Steel Mills, Hydraulic Motor

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 narrowest trench is 400mm wide which can be produced with the ER 250 L or ER 400 L.

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.

Erkat rotary drum cutters; robust, reliable tools

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. Optimum cutting performance is achieved when the hydraulic motor in the drum cutter matches the hydraulic output from the excavator's pumps. Suitable for excavators 10 - 20 tons 65 kW power Fitted with one 65 kW hydraulic motor, recommended for material up to 50 MPa.


Grinders for tree stump removal or cutting

For those looking for the maximum flexibility with a drum cutter excavator attachment, the option of fitting special wood cutting picks into the standard pick boxes allows the drum cutters to achieve reasonable performance in wood cutting applications with low capital expenditure. Increased performance can be obtained from drum cutters supplied with special wood cutting drums fitted with non-rotating cutter teeth.


Auger drive units - Drumcutters

Owners asked whether their longitudinal drum cutters could be used as rotary heads so Erkat designed an adaptor that could be attached to the output shaft for this purpose. Although extremely useful for some applications, the standard longutidinal drum cutter plus adaptor was too long and too expensive for use as a dedicated auger drive unit.


Accessories for use with rotary drum cutters

Rotators are an essential tool to obtain maximum productivity in specialist applications such as tunnel profiling, renovation of large surfaces, profiling diaphragm walls and working in limited space. The complete range of pick boxes are available from stock including heavy duty pick boxes fitted with hardened steel inserts for great wear resistance and longer working life.


drum cutter with cutter wheel or wheel cutter

Cutting short lengths of narrow, shallow trenches in hard material can be a problem especially when the length of trench does not justify the use of a full scale trenching machine. Drum cutters fitted with a wheel cutter provide an alternative solution and under the right circumstances can be extremely cost effective. ER 100 Max wheel dia 650 mm, max cutting depth 210 mm. ER 1200 Max wheel die 1000 mm.
