Interoc: Crawler Rig AN 160

Interoc Drills

INTEROC have for many years been supplying the civil engineering industry worldwide with high-performance drilling systems for a large variety of applications, particularly for ground stabilization. With a high number of units sold into North America, Interoc has already established itself as a leading supplier of high quality and performance equipment.

The robust design, longevity and cost effectiveness of INTEROC products have been proved around the world under the toughest operating conditions.

American Commercial is the exclusive agent for the USA, drills are inventoried in Abingdon Virginia along with parts. At any point in time various rigs are available for lease as well as sale. Service technicians are available to commission and provide after sales service as needed.

The crawler drill AN 160 is intended for heavy duty anchor drilling and micropile drilling applications requiring large-diameter or long-reach drill holes.

The machine frame houses a robust 171 kW liquid-cooled Deutz Diesel engine with latest turbo-charger and intake-air cooling system. This power unit features an eco-friendly fuel-saving EMR (electronic engine control) speed governor which means no exhaust-smoke discharge when load changing.

The hydraulics 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 even when the drill rig is operating at maximum duty when equipped with large version of TIS doublehead system. The drill mast mounted on the AN 160 is designed for running 3 m extension drill rods when fitted with doublehead drill system.

A new type of patented rod/casing magazine allows the drill string to be fitted and removed quickly and safely even in vertical drilling position. The magazine can hold as many as 7 double-rod units, comprising 3 m long sections of inner rods and outer casings up to 219 mm in diameter.

The crawler drill rig AN 140 has been developed in particular for drilling applications with doublehead systems and rod changer.

The machine frame houses a robust 140 kW liquid-cooled Deutz diesel engine BF6M 1013 C with latest turbocharger and intake-air cooling system. This power unit features an eco-friendly fuel-saving EMR (electronic engine control) speed governor which means no exhaust-smoke discharge when load changing. The emission values correspond to the standards of European COM2 and EPA2 US Stage 2 off-highway regulations.

The hydraulic unit operates on the load-sensing principle and can run on biologically degradable fluids. The high drive power output ensures that the drill heads are always well supplied.

 

Interoc: Crawler Rig AN 109

Compact Grout Plants

The drill mast on the AN 140 is designed with a hydraulic motor feed system and feeding and retraction forces up to 8 tons. Optionally a drill mast with cylinder feed can be supplied. A new type of patented rod/casing magazine KBM allows the drill string to be fitted and removed quickly and safely. The magazine can hold as many as 7 double- rod units comprising 3 m long sections of inner rods 76.1 mm and outer casings up to 133 mm in diameter. The drill strings are lifted from the magazine racks by a hydraulic manipulator which then swings them into line with the drilling axis. The same procedure is employed 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 the anchors have been inserted in their holes the outer casings are slid back into the racking system over the inner rods. The sections are then ready for the next twin-rod drilling phase. A time-consuming part of the working cycle is eliminated and the overall drilling time is significantly reduced.

The crawler drill AN 109 B 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 132 kW air-cooled Deutz 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 20,000 Nm.

The drill mast mounted on the AN 109 B is designed for running 3 m extension drill rods/outer casings. A rod/casing magazine allows the drill string to be fitted and removed quickly and safely. The magazine can hold as many as 6 double rod units, comprising 3 m long sections of inner rods and outer casings up to 133 mm in diameter.
