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