Klemm launches universal drill rig

Klemm launches universal drill rig German manufacturer Klemm has unveiled the universal KR 909-1 drill rig.
Aimed at developing markets, the multi-purpose machine weighs 13t, and is designed for a range of civil engineering and geotechnical applications.

The compact design allows work to be carried out on construction sites with tight space restrictions.
According to Klemm, an enhanced mast articulation means stability of the rig is optimised in every drilling position, eliminating the need for additional outriggers and reducing set-up up time.

The desired drilling method can easily be selected, the company said. Options include: pure rotary drilling with a single rotary head unit and down-the-hole (DTH) hammer, top drifter drilling, and double-head drilling in either rotary or rotary-percussive configuration.

The use of on-board hydraulic components makes after-market conversion of the rig to other drilling methods simple, Klemm claimed.

Drilling and driving functions are controlled from a remote console, giving the operator freedom of movement and an optimum view of the work in progress.

Klemm said it had designed the rig to be easily maintanined, and that the machine has the bare minimum of moving parts and complicated functions.

The KR 909-1 has an on-board diagnostics system for engine management and machine control fitted as standard.

In addition, all remote-controlled electronic valves can be also be manually controlled, so that in the event of a machine malfunction, downtime can be minimised.

Also, the electronic circuits have been built to a modular design to improve the process of fault finding and elimination.

Other key features include: a diesel engine with a common rail-injector system, load-sensing hydraulics, and plunger rods with increased corrosion resistance and a chrome-nickel protective coating.
