Drilling rig KR 909-2

Drilling rig KR 909-2

The KR 909-2 is a powerful yet simple structured drilling rig. With tried and tested KLEMM additional components, it can be adapted for a variety of tasks quickly and easily. It is designed for countries with non sulphur-free fuel and for countries outside of the EU and US/EPA.

Powerful, straightforward and quickly convertible – for all standard applications in specialised foundation engineering.

Compact and powerful
The KR 909-2 is a compact and powerful machine which can be easily adapted to a variety of tasks with reliable KLEMM additional components.Suitable for non sulphur-free fuel
The diesel engine is certified in accordance with emissions standards EU Stage IIIA, USA EPA TIER 3. This drilling rig continues to be part of the KLEMM product range (on request) since there are areas outside of the EU and USA/EPA regulatory zone where the current engine-related requirements for the fuel to be free of sulphur can not or not yet be met.

Robust technology
The drilling rig type KR 909-2 has a 129 kW engine power and a dual-circuit load-sensing main pump system. All available crill heads are designed for the same pressure range, so that conversion to other drilling procedures and drill heads is easy, without having to interfere with the machine hydraulics. Simultaneous operation of a heavy hydraulic drifter with a flushing pump, or operation of a double-head drilling system, for example, are possible with the installed engine power.

Remote control
Drilling and tramming functions are controlled and operated by a radio remote control. This frees up the operator to choose where they want to work from, as a perfect view of all working processes is guaranteed. Wired remote control can optionally be retrofitted. Large, easy-to-read manometers provide information on the status of the drilling process. Set-up functions are directly controlled by the hydraulics; they are found on the base machine. A reserve control for drilling functions is available as standard from the factory.

Universal mast
The mast, with an increased cross section and hydraulic feed cylinder, provides a retraction force of 97 kN. This is the basis for all equipment configurations, whether for anchor drilling or for high-pressure injection drilling (HPI).Modular, prepared for any case
Basic machine and drill mast have a modular structure for defined KLEMM components. Without changes to the mechanical assemblies, controls or hydraulics, changing to another drilling system is very easy and quick to carry out. A variety of standard applications are covered with this modularity, e.g.

  • Anchor drilling with common drilling methods such as rotary drilling, auger drilling, rotary percussive drilling, overburden drilling with hydraulic drifter and double rod, double-head drilling with two independent drill heads
  • Micropile drilling, uncased or cased, e.g. with the rotary duplex method
  • Soil nailing and uplift anchor drilling
  • High-pressure injections for installing columns, foundations, or underpinnings with rotary drilling methods
  • Soil exploration

Safe operation
The required drilling spots can be reached practice-orientated thanks to the optimised kinematics, while the design guarantees safe operation in all configurations, without additional jack-ups.
