Bauer Maschinen Group is coming to bauma once again in April where it will showcase its complete portfolio of equipment for specialist foundation engineering in the open-air exhibition area.

In addition to Bauer’s core area of BG series rotary drilling rigs, the duty-cycle cranes of the MC series and diaphragm wall technology – with cutters and grabs – its subsidiaries such as Klemm, Prakla, Hausherr, RTG, ABS Trenchless and MAT will also display their new developments.

At the event, the company will also mark the anniversary of its first rotary drilling rig, the legendary BG 7, which was first used on a construction site exactly 40 years ago. The BG 7 was the prototype for all rotary drilling rigs that have now been built by different manufacturers worldwide for decades.

An attraction at the Bauer booth will be a model construction site for diaphragm wall technology. A BC 35 trench cutter will be displayed on an MC 96 base carrier – with the necessary guide wall on the ground – and a diaphragm wall grab on a GB 46 base carrier will be “working” beside it. Exhibits of the subsidiary MAT Mischanlagentechnik will round off the complete system.

“The MC crane series has been upgraded for more construction methods. The modern winch system with automatic control allows the MC cranes to be used for dynamic soil compaction,” says a company spokesman.

He adds that Bauer now also offers an orange peel grab for MC cranes for material handling work. On this track, a further upgrade of the range of application is planned for 2016, such as a lifting crane with auxiliary jib.

Bauer Maschinen presents a special base carrier for hydraulic diaphragm wall grabs, the GB 46 base carrier, which has been equipped with a new freefall system. The machine can now be offered to the international market with CE and Tier Four. The new DHG-V grab with modular design for trench widths of 600 to 1,500 mm will also be exhibited. A special tooth placement – so-called pick teeth – makes it possible to use the gravitational force of the grab on hard ground.

A core area of its space will be dedicated to four machines for specialist foundation engineering, namely the BG 24 H, BG 28 H, BG 39 and BG 46 heavy-duty rotary drilling rigs. These machines are equipped with different extensions and tools. Performance-enhancing improvements have been made to all machines; and all machines are equipped with the Bauer EEP, the energy efficiency package.

Bauer will present a new generation of ValueLine drilling rigs – a medium-sized platform range that is designed for bored piles with diameters of up to 2.5 m and a drilling depth of up to 70 m. Bauer has succeeded in achieving the best price-performance ratio. This medium-sized platform range includes the Bauer BG 26 as the lowest priced-model and – in the larger version – the BG 30.

Bauer will also showcase some new extension developments, for example an extremely long rack for cutter-soil-mixing. The guide tube on a BG 39 rotary drilling rig is designed for a depth of 42 m. On another machine, the continuous flight auger method will be presented with the new “iCFA” auger string. It features an integrated measurement sensor at the end of the auger, inductive (cableless) data transfer via the hollow stem of the CFA auger and intelligent pull control.
