For large-scale projects or harsh working environments such as on coastal and highlands terrain, the possession of durable and modern machines to ensure construction progress as well as achieve the highest productivity is indispensable.   

Bauer BG42 is a specialty drill, one of the three brothers of the BS115 series from Bauer. Compared to its younger siblings Bauer BG 46 and 50, BG42 is truly one of the “trump cards” in difficult construction projects.

Bauer BG42 background information 


BAUER BG42 is one of the important equipment in works with complex operating conditions but needs large volumes, typically projects such as Cua Luc Bridge or large wind power projects that Duafat Group is underway.  


Currently, along with Bauer BG46, Liebherr LB44, BG42 is one of the main building monsters of Duafat. Being in the group of complex technical solutions helps investors save a lot of time on schedule and solve many difficult geologies.
