Universal and anchor drilling rig

Drilling rig KR 806-3GS

The go-to machine for special foundation work when it comes to anchor drilling with overburden drilling methods and with a double head system. Optimised for less accessible and low-down drilling spots, with efficient, smart and powerful drive train technology. 

The industrial standard for anchor drilling.

The drilling rig type KR 806-3GS is currently the most advanced version from the KR 806 range. Originally designed as an anchor drilling rig for double-head drilling systems, "the 806" is now widely used and highly rated. Today, the "806" range is synonymous with the most modern and high-performance anchor drilling rig on the market.

The drive train
The basis of the drive train is a 175 kW diesel engine with particle filter for emission stages EU Stage V or USA EPA Tier 4 final. A version for emissions stage IV (EU) with 160 kW is still available. A special version for emissions stage 3A (EU) is also available on request. As compared with the previous model, the kinematic assemblies, among other things, have undergone radical new development.  

The hydraulic system
The hydraulic system comprises a dual-circuit load-sensing system with the reliable technologies, Load Limit Control and Power Sharing (patented). The hydraulic valve banks are integrated directly into the CAN bus and have extremely sensitive reactions. They are self-regulating so work independently of the temperature and highly accurately. The Energy Efficiency Package (EEP) includes a power and energy management system which adjusts the engine speed automatically and dynamically to the load and operating state. Fuel consumption and sound emissions are greatly reduced.

Machine kinematics
Rigidity and long-term fatigue strength have been increased significantly and mechanical stress in the joints decreased significantly. The machine kinematics are designed primarily for shallow inclindes bores with deep starting points, and pile drilling with drilling locationslocations sideways to the crawler tracks can now also be carried out.

The ability to control all functions by radio remote control is standard.
The functional safety of the machine controls complies with Performance Level C (ISO 13849), making its design extremely resistant to faults and fail-safe. The ROM and SPM modes are available in the machine in accordance with EN 16228. The machine is pre-fitted for installation of a KLEMM Bohrtechnik interlocking guard.

Maintenance and diagnostics
The display and diagnostics options have been hugely expanded, e.g. there are displays at the operating station for flow regulation of the individual flushing paths. All pump circuits are provided with easily accessible mini measuring ports.

Details and options


Drilling positions beside the oscillation crawler tracks are possible without any problems.

Details and options

Kinematic boom assembly

Kinematic boom assembly with much improved strength and rigidity, optimised for low and inclined anchor drilling spots and with improved set-up options for working beside the crawler tracks

Details and options

Radio remote control

All tramming, set-up and drilling functions are operated by radio remote control (Standard).

Details and options

Control panel

A conventionally operated control panel is available instead of the radio remote control. It is permanently fixed to the machine, is pivotable and parallel height-adjustable.

Details and options

Radio-remote controlled tramming

If the machine is delivered with a conventional control panel, then this small radio remote control is provided for the tramming and oscillating functions.

Details and options

Machine control

Machine control with LCD colour screen and touch-input

Details and options

Surround signal lamp

The safety operating modes (ROM, SPM) and other machine statuses are visualised by a surround signal lamp.

Details and options

Engine compartment

Engine, pumps, cooler, etc. are easily accessible.

Details and options


The drilling rig in the series already has a complete range of efficiency components such as automatic, highly dynamic adjustment of the engine speed to the load sitation, and Power Sharing of the main pump circuits (patented).

Details and options

Oscillating crawler tracks

The crawler tracks can oscillate passively and actively. This improves stability when working on uneven ground and greatly simplifies loading processes on semi-trailer trucks or similar.

Details and options

Component carrier

Component carriers, equipped for additional components such as water pump, compressed air lubricator, multi-channel flushing equipment, washers and hose drum with washing lance

Details and options


An interlocking guard complying with EN 16228 can be delivered for the drilling rig.

Details and options

Rod loader

Rod handling can be simplified, for example, by the MAG 8.3 rod loader with linear magazine.

Details and options

Lateral sliding carriage

Stable, laterally sliding carriage for almost all drill heads and double-head drilling systems

Details and options

Central lubrication points

Regular maintenance and care is made easier by centrally compiled lubrication points.
