Diesel engine drilling rig LRH 200

rotarydown-the-holeconstruction

Product overview
The LRH 200 is a combined piling and drilling rig designed for foundation engineering. Its flexible leader kinematics allow large working radii (up to ~8 m) and inclinations up to 18° in all directions. The in-house hammer concept accepts a range of tamper/ram masses, enabling impact pile driving of concrete, steel or timber piles. As a drilling rig the LRH 200 provides a high-performance drilling drive for single-pass methods (CFA, full displacement, down-the-hole) and can be equipped for soil mixing. The compact carrier is based on the LB 30 platform and can be transported with the leader mounted for fast on-site setup.

Key features

• Flexible leader kinematics for large radii and inclinations up to 18° in all directions.
• Leader vertical travel ±6.5 m (total ≈13 m) for large height adjustment at the working point.
• Transport and rapid setup: carrier and leader transportable in one piece with hydraulic connections minimised.
• Flexible hammer concept supporting a wide range of basic hammer weights (~6,740–18,000 kg) and ram masses (3,000–10,000 kg).
• High-performance drilling drive for single-pass methods (CFA, full displacement, DTH) plus soil-mixing capability.
• Modern operator cabin with air conditioning, ergonomic controls and optimised visibility.
• Diesel-driven powertrain with on-board hydraulics sufficient for additional attachments without external power packs.

Applications

• Pile driving (hydraulic hammer impact, vibratory driving and related methods).
• Continuous flight auger (CFA) drilling and full-displacement drilling.
• Down-the-hole (DTH) drilling.
• Soil mixing / ground improvement (wet mixing, cutter soil mixing).
• Predrilling and other single-pass drilling processes.

Attachments / Optional equipment (examples)

• Hydraulic impact hammers (H-series) with variable ram masses.
• Mixing drives (MA series) for soil mixing applications.
• Rotary/rotary-drive units for pre-drilling and drilling (BA/BAT series).
• Winch automation, attachment recognition and operator assistance systems.
• Digital solutions: MyJobsite, PDE process data recording, LIPOS positioning, LiDAT telematics.
