dh ABSE

Drilling / bolting devices for roadheaders

The dh ABSE is the universal drilling and bolting unit for roadhea-ders with machine weights of 50 t and above.

The hydraulic system of the individual roadheader is used for po-wer supply, a separate power pack is available as an alternative. A radio remote control unit serves for precise and quick operation of the drilling/bolting device.

The entire rig with its drill boom and drill feed is mounted on a traversing track which is additionally relocatable on the roadhea-der by a shifting cylinder. Changeover between parking and wor-king position is achieved in less than half a minute.

Thus, the parking position guarantees an unhindered cutting operation of the roadheader and drilling/bolting operation is possible in front of the cutter head.

The telescopic boom with its double rotation device ensures ra-pid and precise positioning to all drilling patterns for roadway bolting as well as to all drilling patterns in roadway direction. Thus e.g. blast holes during difficult cutting conditions, explorati-on, degassing or stress relief holes or drill holes for face reinforce-ment can be drilled.

Tailor-made drill feeds with numerous fittings allow optimal ad-aption to the various drilling and bolting applications and road-way profiles.

Powerful, reliable and wear resistant drifters (dh DP15 series) and rotary drills (dh DR series) ensure short drilling and bolting cycles.
