Roadheading Excavator | HRE

Roadheading Excavator Brochure

Especially designed for the effective drifting of tunnels and galleries with small cross sections of 9m² to 22m², the HRE combines the advantages of:

  • A road heading machine
  • A flexible drilling jumbo
  • An effective excavator

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.

Description

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 and 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.
