Robust. Ideal for CFA applications.
Performance and stability
With 175 kW, the KR 710-3G has a very high power for this weight class. The stable chassis ensures sufficient stability for pile drilling work, even with maximum drill mast equipment.
High torque
The new motor-powered drill mast type 330 has higher selection modulus, meaning higher torques than before can now be transferred (up to 62 kNm). 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
A short mast version of type 330 makes it possible to work under a room height of min. 5 m.
High Drill mast retraction force
The drilling rig has a newly developed drill mast that offers maximum retraction force of 220 kN - ideal for larger pile lengths and diameters. Despite the significantly higher tensile force, a new pump circuit ensures the well-known high advance and retraction speed.
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.
Energy-efficient work
As with nearly all KLEMM drilling rigs, the equipment with the EEP package (EEP = Energy Efficient Power) is standard, also with the KR 710-3G machine. This significantly reduces fuel consumption and noise emissions.
Large drilling diameters
A new clamping device type 35, with special clamping jaws for continuous augers with a diameter of up to 800 mm and for casing pipes with a diameter of up to 890 mm, has been developed for centering and intercepting augers and casing pipes.
