Overview of different brackets
Pro bracket – rigid bracket, flexible use
ER 1500 with pro bracket
The rigid intermediate bracket offers guaranteed protection for the customer investment with the same well-known performance. The hydraulic hoses are fed out to the back, in the centre of the extension arm protection. The hoses are exposed to less mechanical strain and therefore better protected during work with minimal visual contact.
Available for ER 650 – ER 2000
Dust suction hood
ER 50 with dust suction hood
For indoor use where water spraying is not possible, we also offer small drum cutter models with a dust suction hood for dry dust collection.
Available for ER 40 – ER 100
Water spraying system
ER 2000 with water spraying system
Our water spraying solution comes with a simple idea: to spray the water directly onto the cutting head area so the water is applied at the actual location itself.
Available for ER 40 – ER 5500
