Pro bracket – rigid bracket, flexible use

Drum cutter with pro bracket

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.
