Roadheading Excavator | HRE

Quick loading, minimal space requirement as well as an optimized switching from mucking to drilling operation clearly distinguish the HRE from conventional systems.

It is the innovative boom which especially determines the performance. It is fitted with a vertically as well as horizontally working parallel holding kinematic system. Besides the bucket and the drilling unit nearly all attachment devices such as hydraulic breaker and cutter heads may be installed via a hydraulic quick-change unit.
