Bauer launched two specialist foundation systems at the Bauma China 2018 exhibition – the GB 80 S hydraulic grab system and BCS 40 cutter system. The Bauer GB 80 S grab system is a combination of Bauer’s tried-and-tested GB series carriers and DHG V grabs. Bauer engineers worked closely with customers and partners during the development to maximize efficiency without adding complexity. The 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. The service platform integrated in the new BT 80 base carrier makes it easier for service and maintenance.
Dieter Stetter, chairman of the management board, Bauer Maschinen, said: “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.”
The Bauer BCS 40 cutter system, produced in China, is designed for cutting depths of up to 40 m. Its compact design makes its suited to 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. The cutter system also benefits from low fuel consumption and ease of use. The first cutter systems of this type have already been successfully tested and used in China since early 2018.
Bauer also exhibited two rotary drilling rigs – the Bauer BG 30 with BV casing oscillator and a BG 55 with a double-head system. Both machines are designed to 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 notable 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 enables the use of a BV oscillator.
