Universal and anchor drilling rig

Drilling rig KR 801-3GK

The most powerful universal and anchor drilling rig from KLEMM with long-reach kinematics.

Long reach thanks to articulated boom. High-performance with 129 kW engine output.

A class of its own
The KR 801-3G defines its own class of especially compact and at the same time universally usable drilling rigs. The model with the denomination “K” is the kinematic variant with an articulated boom, and offers a maximum reach capability to drill small and medium-sized drill holes, above and under the set-up area of the drilling rig.

Unique kinematics
The capability to swivel the boom up to 90° over the right hand crawler in combination with powerful hydraulic drifters (KD series) or rotary heads (KH series) makes the KR 801-3GK ideal for securing sloops and excavations with self-drilling anchors, or cased soil nails. Applications for inclined or vertical drill holes are covered by this unique kinematic which includes a 360° rotator.

For hard-to-reach drilling points 
Special focus lies on the suitability of this machine for extremely confined conditions. This is shown on the one hand by the compact dimensions (2.2 m in total width) and, on the other hand, by a newly developed mobile radio remote control. The very carefully and precisely designed build of the machine base makes additional jack-ups unnecessary. This makes the set-up of the drilling rig on the next drill hole very efficient.

Energy efficiency
The utilisation of a fuel-saving, dual pump, load-sensing hydraulics together with benefits of the Energy Efficiency Package (EEP - power and energy management system) achieves an extremely efficient hydraulic supply of the respectively active consumers on the drilling rig. The operation of the newest generation of rotary heads with high-pressure hydraulics and an operating pressure of 350 bar maximum is a trend-setting feature.

Safe working
The newly developed machine exterior trim sets new standards in ergonomics, maintainability, noise emission, permissible ambient temperature and design. 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 advantages


Thanks to its universal kinematics with large reach, many fields of application are possible.


The drilling rig facilitates various configurations of the drill system, and the drill mast design.

Large boom reach

Further-away drilling locations are can be reached with the articulated boom.


The optional KLEMM DataLink AIR module for the transfer of machine, process and service data into the cloud.

Can be adjusted to the task at hand

  • Lubricator for downhole drifter operation
  • Water pump for water admixture against development of dust
  • Washing lance with hose drum, including connection to water pump
  • Flushing pumps for water flushing

Details and options

Engine compartment

The engine compartment is easily accessible for maintenance purposes.

Details and options

Machine control

The machine control is protected but still easy to access. A colour LCD display and operator panel visualise important machine parameters and simplify use interaction.

Details and options

Manometer box

A manometer box with large, easy-to-read manometers for the most important operating pressures can be attached to the drilling rig.

Details and options

Component carrier

The drilling rig has a component carrier for the assembly of various optional component, e.g. for a washer and/or a compressed air lubricator. 

Details and options

Radio remote control

Drilling, tramming and set-up functions can be controlled safely with radio remote control (standard). The entire machine control complies with the fail safety requirements of EN 16228.
