The Bauer GB46 hydraulic grab bucket purchased by Tianjin Geological Foundation Engineering Co., Ltd. at the end of 2013 has recently begun work at the Meijiang Convention and Exhibition Center Station of the Tianjin Metro. At the same construction site there is also a Bauer GB34 hydraulic grab bucket that has been in service for many years.

The Bauer GB46 and GB34 hydraulic grab buckets have delivered outstanding performance, completing more than 20 diaphragm wall panels in just over one week. The general contractor is highly satisfied with the trench quality and efficiency of the Bauer equipment.

The Bauer GB46 hydraulic grab bucket is manufactured by Shanghai Bauer Machinery Co., Ltd., the wholly owned Chinese subsidiary of the German Bauer Group. The product features a fully synchronized double winch system, a foundation engineering-specific chassis developed in-house by Bauer, and the German-made B-Tronic monitoring system, which accurately displays the verticality of the trench and provides real-time monitoring of all equipment components. An optional GV3 bucket rotation device enables trenching under confined site conditions. These features fully reflect the Bauer grab bucket's characteristics of high trenching accuracy, fast excavation efficiency, and low fuel and wire rope consumption. Shanghai Bauer also produces hydraulic grab buckets such as the GB34 and GB60 models. Over the years, Bauer hydraulic grab buckets have won widespread praise from users and general contractors for their good trench verticality, high excavation efficiency, low fuel consumption, and long service life, making them the preferred model for many engineering projects.
