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. Erkat rotators are extremely robust as they have been designed to withstand the extremely high forces generated while working with rotary drum cutters. The materials chosen for the worm gear components provide mating surfaces capable of transmission of these forces with maximum wear resistance.
Hydraulic oil flow is directed through an orbital distributor to enable the drum cutter to be rotated through a continuous 360 degress with hoses becoming tangled. The range of rotators currently available are:
- ERU 1 for excavators from 3 - 8 tons
- ERU 2 for excavators from 9 - 15 tons
- ERU 3 for excavators from 15 - 25 tons
- ERU 5 for excavators from 34 to 50 tons
Adaptor plates can be supplied for all excavators and standard quick couplers provided relevant information is available. If the make or model of attachment is unknown please download the drawing from the section below and provide us with the dimensions shown.
To ensure the strength required to work with drum cutters, we recommend that adaptor plates are made from the following thickness steel plate:
- ER 50 15mm plate
- ER 100 20mm plate
- ER 250 - 600 25mm plate
- ER 650 30mm plate
- ER 1200 - 5500 40mm plate
The majority of picks shown in the Erkat catalogue are available from stock including picks fitted with the unique QuickSnap clips. Picks with QuickSnap are only available from Drumcutters Ltd or Erkat and make the changing of picks quicker and easier.
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. Worn inserts can replaced once. Contact us for details on how to change inserts.
