Anchor Drill Rigs
Anchor Drill Rig AN 120
The anchor drill AN 120 is a well-proven multi-purpose drill rig for anchor drilling in ground stabilization, but also intended for many other drilling applications.
The machine frame houses a robust 119 kW liquid-cooled diesel engine with turbo charger. The particularly reliable hydraulics unit can run on biologically degradable oils. The high drive power output allows to drill with powerful hydraulic hammers and rotary heads with a rotation torque up to 1.500 daNm. The patented rod/casing magazine allows the drill string to be fitted and removed quickly and safely.
Anchor Drill Rig AN 150
The anchor drill rig AN 150 has been developed in particular for drilling applications with double head systems and rod changer.
The machine frame houses a robust 149 kW liquid-cooled Cummins diesel engine with turbocharger and intake-air cooling system. The hydraulic unit operates on the load-sensing principle and can run on biologically degradable oils. The high drive power output ensures that the drill heads are always well supplied. The patented rod/casing magazine KBM allows the drill string to be fitted and removed quickly and safely.

The drill-strings are lifted from the magazine racks by a hydraulic manipulator, which swings them into line with the drilling axis. The same procedure is used for drill string removal with the manipulator returning the inner rods and outer casings to their racks. For overburden drilling, as used for example for anchor jobs, the inner string is detached first and replaced in the rack. After inserting the anchor into the hole the outer casings are slid back into the rack over the inner rods. The sections are then ready for the next double rod drilling phase. A time-consuming part of the working cycle is eliminated and the total drilling time is significantly reduced.
The magazines can hold up to 7 double rod sets, consisting of 3 m long sections of outer casings and inner rods or augers. For special drilling operations customized rod changers / rod magazines are available with different dimensions.
