With the successor to the KR 707-1W series of drilling rigs, Klemm is expanding its product range in near-surface geothermal drilling sector. This sector reaches from the construction of single-family homes through to large scale projects with several dozen boreholes on one construction site. Borehole drill depths of up to approximately 200 m can be drilled.
In comparison to competitor machines, the integration of a pendulum chassis and a slewable articulation provides special off-road mobility and the flexibility of setting up the drill mast at the drill attachment point.
The KR 708-3GW can be used wherever the most difficult construction site situations arise, for example in the retrofitting of geothermal heating systems on existing structures in the so-called refurbishment business.
With the double-head drilling system provided as standard, a wide variety of soil formations are mastered quickly, and at little risk. A drill mast equipped with a retraction force of up to 100kN and the protective casing rotary drive with a maximum torque of 24kNm allows large casing depths should the probe borehole need to be sunk in unstable ground.
A lifting device attached to the double-head sled facilitates the handling of the probe reel, which is used to install the geothermal probe in the borehole. In addition to a Euro V-certified diesel engine, Power Sharing - developed and patented by Klemm Bohrtechnik, and the EEP Energy Management System are additional modern technologies that are used to conserve resources and protect the environment.
