Premiere at Bauma China: Bauer presents innovative grab and cutter technology

Ever since the first Bauma China, the fair that is held in Shanghai in late autumn has been an important date in the calendar of the BAUER Maschinen Group. This year, the Bavarian company is again represented with two booths and presents the latest developments in equipment, as well as proven technology in the field of specialist foundation engineering, on 600 m2 of floor space. On the first day of the fair, visitors to the Bauer booth were able to experience two world premieres up close: The GB 80 S hydraulic grab system and the BCS 40 cutter system are two new specialist foundation systems that Bauer presents at the show.

The BAUER GB 80 S grab system is a perfect combination of tried-and-tested GB series carriers and state-of-the-art DHG V grabs. Dieter Stetter, Chairman of the Management Board of BAUER Maschinen GmbH, explains: "The new generation GB 80 S has been developed to master the increasingly complex working conditions on diaphragm wall construction sites. It is a completely new machine in a new performance class." Bauer engineers worked closely with customers and partners during the development to maximize efficiency without adding complexity. The BAUER GB 80 S covers all possible applications of the DHG V grab and thus the entire spectrum of tasks that can be performed by a hydraulic grab. With it, trench widths of up to 1,800 mm can be excavated to 80 m depth. In addition, the hydraulic system and two single-layer winches have been optimized in order to reduce fuel consumption and wear. Thanks to the service platform integrated in the new BT 80 base carrier, service and maintenance can now be carried out even easier and save.Bauer team at Bauma China in Shanghai.

As a second novelty, Bauer introduced the BCS 40 cutter system – the first time the BAUER Maschinen Group presented a diaphragm wall cutter at a Bauma in Shanghai. This new machine, produced in China, is designed for cutting depths of up to 40 m and, thanks to its compact design, can ideally be used in inner-city areas. This cutter system combines three of Bauer's long-established systems for the first time: the BC 32 trench cutter, the HSS 40 hose guide system and the MT 120 carrier. Low fuel consumption and ease of use make it an extremely effective equipment. The first cutter systems of this type have already been successfully tested and used in China since early this year.

Needless to say that BAUER Maschinen Group also exhibits two rotary drilling rigs: a BAUER BG 30 with BV casing oscillator and a BG 55 with a double-head system. Both machines meet the increasing demand for cased bored piles and secant pile walls in the Chinese market. The BG 55 achieves much higher performance compared to the Kelly drilling method for comparable drilling tasks and geological factors. A great feature of the BG 30 is the longer crowd cylinder with more retraction force. This allows for the handling of longer casing segments for cased Kelly piles. A stronger UW 100 undercarriage makes the use a BV oscillator possible. The BAUER BG 30 thus offers ideal performance for the construction of secant bored pile walls.
