Bauer can also refer to a special anniversary: the first Bauer rotary drilling rig, the legendary BG 7, was first used on a construction site exactly 40 years ago. This first drilling rig was the prototype for all rotary drilling rigs that have now been built by different manufacturers worldwide for decades. At that time, the only available equipment for pile bores came from other construction areas and had to be temporarily converted for the new procedures.

Diaphragm wall technology: MC duty-cycle crane and GB base carrier

An attraction at the Bauer booth is 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.

Generally, the MC crane series from Bauer was upgraded for more construction methods. The modern winch system with automatic control allows the MC cranes to be used for dynamic soil compaction. Additionally, 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 e.g. as a lifting care with auxiliary jib.

The MC cranes offers a significant expansion for use in diaphragm wall technology. The Bauer designers have elaborated the HDS hose drum system: with HDS-T on the mast head – exhibited on the BAUER MC 96 duty-cycle crane –, the cutter can be turned together with the hose bracket. Cutting depths of up to 120 meters are possible with this design.

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 4. The new DHG-V grab with modular design for trench widths of 600 to 1,500 millimeters will also be exhibited. A special tooth placement is possible for hard ground, so-called pick teeth. With it, it is possible to use the gravitational force of the grab on hard ground.

Bauer drilling rigs: PremiumLine and ValueLine

In order to be variably prepared for the demands of the market, in 2011, BAUER Maschinen GmbH introduced two lines of drilling rigs: the ValueLine and PremiumLine. While the PremiumLine rigs are multifunctional machines for different uses in specialist foundation engineering, the ValueLine is optimized for kelly drilling.

Bauer will exhibit a core area of the machines for specialist foundation engineering at Bauma 2016 with four heavy-duty rotary drilling rigs. The multifunction features of the machine series will be illustrated – in particular, these are models BG 24 H, BG 28 H, BG 39 and BG 46. The four machines are equipped with different extensions and tools. Performance-increasing improvements have been made to all machines; all machines are equipped with the Bauer EEP, the Energy Efficiency Package.

The BG 24 H will be presented with the new BT 75 base carrier, with significant safety-relevant developments. There is an integrated service platform for easy, convenient and secure access for maintenance work. The practical service platform can be pulled out like a drawer, so the motor paneling automatically becomes the fall protection. The BG 46 rotary drilling rig puts the focus on heavy-duty casing work without a casing oscillator and is optimally prepared for deep drilling in a kelly system.

At Bauma 2016, Bauer Maschinen will also present a new generation of the ValueLine drilling rigs – a medium-sized platform range that is designed for bored piles with a diameter of up to 2.5 meters and a drilling depth of up to 70 meters. With a view to customer-specific benefits, functionality and profitability, 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.

The core element of the medium-sized platform range is the joint BT base carrier, which was entirely designed and constructed by Bauer. The modern and highly functional support does not just score points for its high safety standards and very low noise emissions. The machine can also be equipped with a 298 kilowatt CAT C 9.3 motor, which fulfills the most recent emission standard according to Tier 4 final. Large cross-sections in the hydraulic pipes and a degree of optimal motor efficiency guarantee economic fuel consumption. For difficult ground conditions, a BTM torque converter or a casing oscillator can be attached.

But the ValueLine medium-sized platform does not just stand out due to its productive capacity, but also thanks to the numerous developments that make maintenance work, assembly and dismantling of the machine easier. An integrated service platform allows for easy, convenient and secure access for all types of maintenance work on the uppercarrige. For this, a step that is connected with a part of the lateral paneling is pulled out of the uppercarriage. The lateral paneling then acts as fall protection. This system is the only one of its kind in the world and sets a new standard in the area of safety at work. All service points can now be easily reached from the ground or from the platform. No compromises have been made in the area of comfort either, which is proven by the Bauer comfort cabin, that is characterized by the highest functionality and allows for an optimal view of the drilling location.

Bauer Maschinen 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 meters. 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 (cabelless) data transfer via the hollow stem of the CFA auger and intelligent pull control, a major step forward in safety and improved productivity.

The subsidiaries of BAUER Maschinen GmbH – Klemm Bohrtechnik, RTG Rammtechnik, Hausherr, ABS Trenchless, Prakla and MAT Mischanlagentechnik – will also present numerous exhibits. Klemm will show six rigs – a new generation of drilling rigs that fulfill the standards of Stage IV exhaust emissions (EU) or Tier 4 final (EPA) with a completely re-developed drive module. The new, improved-performance KR 709-3G (micro) pile boring machine, the compact anchor drilling rig for KR 805-3G overburden drilling and the successor in the tried-and-tested KR 806 series, the KR 806-3G will also be exhibited. Additionally, the KR 909-2 drilling rig with the new MAG 2.5 drill string magazine and the new KH 21 rotary drive and a drill string handling module from the HBR 120 series will be displayed. The reworked KR 806-5G will be Klemm's largest exhibit: a drilling rig with an especially large single-pass installed depth. The redeveloped KR 801-3FK, a drilling rig with an especially extensive boom reach, completes the range of exhibits.

Hausherr will be represented by the largest rig of the model HBM 160 (160 kilo newton of pressure). ABS Trenchless will showcase a solution for an ABS 600 horizontal drilling rig with changeable CRB 100 rock boring equipment. Prakla shows the mobile rotary drilling rig RB 60. This rig with up to 600 kilo newton hook load capacity has been completely reworked and upgraded, technically as well as power-wise. The RB 60 universal drilling rig enables to drill with different methods, for example rotary-drilling with direct circulation or with reverse circulation, down-the-hole hammer drilling or free-fall drilling, with borehole diameters of up to 1.200 Millimeters.

RTG Rammtechnik GmbH is the competence center for telescopic leaders and vibratory pile drivers to vibrate sheet piles within the BAUER Maschinen Group. The subsidiary will present two pile drivers. As in previous years, RTG is still consistently pursuing the goal of higher efficiency and considerably decreased noise emissions in connection with a significant reduction of fuel consumption. This has already been impressively achieved with the BS 65 RS base carrier and will now be comprehensively expanded through further measures. Included in this is the complete development and use of the Bauer EEP package on the RTG base carriers. In doing so, a fuel consumption saving of up to 20 percent and a further noise reduction are achieved. The world premiere of RTG's soundproofed vibrator will take place at Bauma 2016. This type of isolation is only possible through the RTG vibrator's patented and unique lubrication and cooling system.

MIDOS technology nominated for the Bauma Innovation Award

Once again, Bauer is nominated for the Bauma Innovation Award (category research). The MIDOS technology (Mixed Drilled Offshore Steel) by Bauer is a future solution for offshore foundations, for example for oil and gas platforms or windparks. The MIDOS pile is based on the Mixed-in-Place method, conventionally used for special foundation works. This technology minimizes the number of offshore operations and is therefore significantly quicker than injection piles and therefore more cost effective. With respect to the driven pile MIDOS is generally a more quite technology and additional technical actions for noise reduction are not required. MIDOS therefore is also ideal for use in noise-sensitive coastal areas.
