Robust. Ideal for CFA applications.
Performance and stability
With 160 kW, the KR 709-3G has a very high power for this weight class. The stable chassis ensures sufficient standing stability for pile drilling work, even with maximum drill mast equipment.
High torque
The new, motor-powered drill mast type 303 has higher section modulus, meaning higher torques than before can now be transferred (up to 53 kNm), among other things. For limitation and control of the Feed force, a new, remote-controlled hydraulic circuit has been developed which is an integral component of the drill mast.
Low headroom
With drill mast type 303, a detachable upper part of the drill mast facilitates working below a headroom of min. 7.6 m.
Energy-efficient work
As with almost all KLEMM drilling rigs, the Energy Efficiency Package (EEP) is also included as standard with the KR 709-3G machine. This significantly reduces fuel consumption and noise emissions.
Safe operation
The radio remote control of the drilling rig for all drilling, tramming and set-up functions is in accordance with EN 16228. The drilling rig complies with EN 16228, and the "SPM" mode (Special Protective Mode) is available for working without a guard under special circumstances, and the "ROM" mode (Restricted Operation Mode) for manually changing the drill rods.
Powerful hydraulics
The hydraulics system rests on a load-sensing double pump and a volume flow control independent of the load. For this new development, the operating pressure for drilling functions was increased to 350 bar.
Large drilling diameters
A new clamping device type "L", with special clamping jaws for continuous augers with a diameter of up to 610 mm and for casing pipes with a diameter of up to 660 mm, has been developed for centering and intercepting augers and casing pipes.
Advantages
Can be adjusted to the task at hand
- Rotary heads up to 54 kNm torque, e.g. KH 62
- 4" concreting swivel and lateral sliding carriage
- Hydraulic clamping devices for casings up to max. ø 660 mm
