Rotary hydraulic drive system EBA 2800

Product overview
The EBA 2800 is an excavator-mounted rock cutter designed for trenching, profiling and drilling in rock and reinforced concrete. It is intended for use on 20–40 t excavators and connects via an H 80 Type output drive. The unit is equipped with a PH 22 pick box and supplied with a standard pick set (22/46/38/22 H).
