Bauer Maschinen’s in-house exhibition this year took place from 16 to 18 April in Schrobenhausen, Germany, drawing more than 1,400 customers, partners and industry experts from around the world.
One of the highlights was the introduction of the Bauer BG 50 rotary drilling rig, the successor to the popular BG 45 in the V-kinematics class. The new model offers increased torque and enhanced drilling performance, as well as a new carrier unit, the Bauer BT 145. The single-pass drilling depth has been increased by 7% and the main winch pulling force by 11%.
The new BG 50 is designed for high hydraulic performance and, with 470 kW, also provides 8% more diesel power. Mobilisation and demobilisation are now easier, as the extended mast can be erected without an auxiliary crane.
Meanwhile, the BG 30 H can be converted into a low-head version in just a few simple steps, making it suitable for construction sites with limited working height. Thanks to optional mast extensions, the drilling rig can be optimised for various project-specific installation heights.
The BG 36 H drilling rig, which was introduced at bauma, was also on display. A key feature is its quick convertibility from the Kelly method to the continuous flight auger (CFA) method. All Bauer rotary drilling rigs are equipped with the B-Tronic 5 control system, which incorporates an intuitive user interface and can be individually personalised through user profiles and display customisation.
Piling technology
The RG 22 S pile driver from RTG Rammtechnik was another highlight. It is suitable for Kelly drilling and features a new kinematic system with a wide range of motion. Thanks to the FreeLock system, the swivelling mast can be positioned continuously between −90° and +90°. An integrated Kelly mast head enables both Kelly drilling and single-pass operations. Additional features include a permissible torque of up to 240 kNm, a pulling force of up to 600 kN for single-pass applications, and a free-hanging load of up to 30 t with the mast unsupported. A larger counterweight of up to 17.2 t provides greater stability.
RTG also showcased an RG 19 with a telescopic leader, an eRG 21 T hybrid, and the MPZ 700-800 sheet pile driver. The latter can be used for sheet pile widths with Z-profiles ranging from 700 to 800 mm. A hydraulically lockable rotating device, higher stroke speeds during pressing and pulling, and an automatic programme further enhance efficiency and ease of use.
Klemm drilling rigs
Klemm Bohrtechnik’s electro-hydraulic, zero-emission KR 806-3E drilling rig significantly reduces noise and dust emissions. With a mains connection and an additional battery, the machine can be operated flexibly and is ideal for construction sites with stringent emission-reduction requirements.
In addition, the KR 801-3GK universal drilling rig is fitted with a 90° swivelling articulated boom. A compact design, a 129-kW motor and modern radio remote control ensure high performance and flexible application options, even on confined construction sites.
The KR 710-3G builds on Klemm’s KR 709-3G, delivering a more powerful rotary drive and higher retraction forces to boost drilling productivity during pile construction and high-pressure grouting.
For geothermal applications, Klemm offers the compact KR 708-3GW, which is specifically designed for installing geothermal loops. Energy-efficient hydraulics, flexible kinematics and optional add-on technology enable versatile applications even on space-restricted jobsites.
Other exhibits comprised the RB 65 universal drilling rig for well construction, geothermal energy and exploration, as well as mixing, pumping and separation technology from Bauer MAT Slurry Handling Systems, including a CMS 50 mixing plant, an IPA 460 injection plant, and an HPI 800 high-pressure pump.
