Especially designed for the effective drifting of tunnels and galleries with small cross sections of 9 m2 to 22 m2 the HRE combines the advantages of
All components have already been successfully used in mining or tunneling under tough conditions.
Blast hole drilling as well as charging, loading, scaling and rock support are possible with only one machine.
Thus any passing situations in tunneling are completely avoided.
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.
