Bauer Maschinen Group will have 18 large exhibits along with numerous smaller innovations from the world of special foundation engineering. The company’s ‘Bauer City’ will cover an area of roughly 2,750 sq m.
The BG 55 will be the largest drilling rig at Bauer’s booth, featuring V-kinematics that offer a high level of rigidity for difficult applications. Equipped with a CCFA package (Cased Continuous Flight Auger) and the new Bauer Torque Multiplier (BTM), the BG 55 sets new standards for drilling depth and diameter.
The BG 30 H showcases the FDP method (Full Displacement Pile), a particularly sustainable option thanks to excellent material excavation performance and low fuel consumption. Another drilling rig exhibited by Bauer highlights the fact that despite all multifunctional innovations, the standard Kelly drilling method still remains a focus in equipment design.
Since late 2024, the Bauer BCS 185 power pack cutter system has demonstrated its performance capacity on the Grand Paris Express project. This unit is based on the established BCS 185 cutter system, yet features a modular drive concept. Instead of a permanently installed motor, an electric or diesel power pack can be used as required. Thanks to this flexibility, it is possible to operate the system either locally and emission-free with electric power, or conventionally with diesel. The diesel HD 1400 can also be equipped with a Silent Kit to reduce noise emissions, while the HE 1400 electric power pack enables a significant further reduction in noise levels. Another innovation is the variable positioning of the power pack, which can be attached on the side, rear or even apart from the machine depending on the spatial conditions. Thanks to the BCS 185 power pack, the construction of diaphragm walls has never been so sustainable.
A construction site nearly without noise and fumes? The eRG 21 T hybrid from RTG Rammtechnik demonstrates how it’s done. The innovative drive combines the power of a 430 kW diesel engine and the precision of an electric motor with up to 88 kW of extra power (standard power supply connection: 125 A / 400 V). The combination of the two drives makes it possible to keep efficiency at a consistently high level despite stringent emission requirements. The diesel engine works at reduced capacity, aided by the supporting electric motor, resulting in a significant reduction in both CO2 emissions as well as noise levels. Hybrid operation reduces fuel consumption, and thereby also CO2 emissions, by up to 68%. The hybrid equipment also delivers excellent versatility: with a considerable performance capacity, it can handle even the most demanding of pile driving tasks without a problem.
Klemm Bohrtechnik’s drilling rigs at bauma will include compact models with variable kinematics systems, powerful anchor drilling rigs and energy-efficient geothermal drilling rigs. For instance, the newly developed KR 717-3GW features a motor capacity of more than 250 kW and is designed for drilling depths of greater than 400 m. The functionalities are extended through a newly developed clamping and breaking device as well as a lateral sliding double-head drilling system.
Other highlights from Klemm include the KR 806-4GM with power-sharing system to reduce fuel consumption and the KR 805-3GW for geothermal drilling at depths of greater than 300 m. All rigs are characterised by high efficiency, modern control systems and powerful technology.
The Multi Shaft Mixing System (MSM) from RTG Rammtechnik GmbH sets new standards in special foundation engineering. With four independent rotary drives and parallel mixing paddles, the system offers more flexibility than conventional triple drives. Continuous feeding in of cement slurry ensures fast and efficient soil mixing. The MSM system has versatile applications, for example in the construction of cut-off walls, groundwater barriers, dike rehabilitation and excavation pits.
The new sheet pile press from RTG will be exhibited on an RG 19 T at the booth of terra infrastructure (FN.720/2). This enables the continuously adjustable use of Z profiles (700 to 800 mm) and rapid hydraulic fine-tuning of the clamping jaws. An increased volumetric flow ensures high pressing speeds of up to 9.4 m/min during extension and 12.0 m/min during retraction. Innovative automated pressing systems and attachment assistants allow for optimised operation.
Bauer MAT Slurry Handling Systems will also showcase its products. For instance, the new CMS 50 mixer – the successor model to the successful CMS 45 – delivers 10% enhanced performance, a more precise, intelligent and self-learning control system for exact dosing. A completely new development, the electric and fully automated IPA 250 grouting station features an impressive pumping rate of 250 l/min and the latest technology. New arrivals in the area of separation technology include the BD 30-C decanter centrifuge with a maximum capacity of 30 cu m/hr and the compact BE 100 desanding plant for geothermal projects.
Last but not least, Eurodrill GmbH, the Bauer Maschinen Group’s specialist for hydraulically operated rotary heads and impact drill hammers, will present its products at booth FN.523/6.
