BG 20 H Rotary Drilling Rig

Product catalog summary
Overview: The document details the BG 20 H rotary drilling rig by BAUER Maschinen GmbH, covering its technical specifications, equipment options, and supported drilling methods.
Specifications: The BG 20 H weighs approximately 58.5 tons and is suitable for various drilling applications, including cased and uncased boreholes, CFA drilling, and cutter soil mixing. It stands at 21,920 mm in height and features a rotary drive with a nominal torque of 200 kNm at 300 bar.
Drilling Methods: The rig supports Kelly drilling, CFA drilling, and full-displacement piling, equipped with hydraulic and electric installations for both cased and uncased boreholes. It can use a hydraulic oscillator for casing installation.
Technical Specifications: Powered by a CAT C7 engine with 205 kW output, the rig has a two-circuit hydraulic system with 300 bar pressure and 146 kW hydraulic power. The undercarriage is retractable, with track widths of 2,300 mm retracted and 3,600 mm extended.
Standard Equipment: Includes a rotary drive KDK 200 K, main and auxiliary winches, a PLC processor for control, and an automatic vertical alignment system. The operator's cab features air conditioning, a radio, and a CD player.
Optional Equipment: Options include a multi-geared rotary drive, higher capacity auxiliary winch, electronic monitoring systems, and various drilling attachments. Additional options include a compressor, generator, and bio-degradable oil filling.
Transport Data: Transport dimensions and weights are provided, noting that optional equipment can affect overall weight. The mast can be configured in sections for efficient transport.
Applications: Suitable for foundation work, soil mixing, and displacement piling, the BG 20 H adapts to various site conditions and project requirements.
Additional Specifications:
1. Drilling Depth: 13.80 m with auger cleaner (without Kelly extension), 19.80 m with Kelly extension; 14.80 m without auger cleaner (without Kelly extension), 20.80 m with Kelly extension.
2. Max Drilling Diameter: 880 mm.
3. Max Extraction Force: 260 kN; 600 kN with main and crowd winch.
4. Max Crowd Force: 205 kN plus auger weight.
5. Continuous Flight Auger Length: 16.18 m.
Specific Applications:
1. Front-Of-Wall Drilling (FOW): Diameter 406 – 610 mm, Depth approx. 14.0 m.
2. Vibrodisplacement (VD): Crowd force 100 kN, Depth approx. 13.1 m.
3. Cutter Soil-Mixing System (CSM): Thickness 500 mm, Depth approx. 12.5 m.
4. Full Displacement Piling (FDP): Diameter 410 – 510 mm, Depth approx. 14.5 m.
Design and Process Improvements: Specifications and materials may change without notice. Illustrations may show optional equipment and not all configurations. Data is indicative only.
Mast Options: The standard 18 m mast can be replaced with a segmental mast. For low-headroom applications, upper mast segments are removed, resulting in a 12 m Kelly drilling rig.
