RB 65: Versatile multipurpose drilling rig for water, energy and mining

• Mobile multipurpose drilling rig for demanding drilling projects
• Modular design for various drilling methods
• Reduced noise emissions, energy efficiency and an optimized hydraulic system

Munich, Germany – BAUER Maschinen GmbH renowned as a specialist in powerful foundation technology. But the company's product range also includes equipment that that goes beyond construction foundations, dam seals, and other applications, setting new standards in a variety of fields. Bauer presented one of these, an RB 65 from the latest generation, at the bauma 2025 in Munich. The mobile multipurpose drilling rig is ideal for challenging drilling projects in the field of water extraction (e.g., aquifer solutions, high-quality drinking water or irrigation wells), energy (e.g. geothermal heat and long-distance energy), and mining (e.g., exploration, raw material extraction, and dewatering). 

Technical features and applications

The RB 65 is designed for a variety of geological conditions. Depending on the geology as well as the size and weight of the drilling tool, small-diameter boreholes can be drilled to a depth of 1,550 meters as well as large-diameter boreholes with a diameter of up to 1,200 mm to a depth of approx. 400 m. This makes it perfectly suited for applications such as the development of aquifers, geothermal drilling and raw material extraction.

Modular design and automation 

Thanks to its modular design, the RB 65 can easily implement a variety of drilling methods, including direct flush drilling and reverse circulation drilling, hammer drilling and rope core drilling. Its compact design is suited for use even in locations with limited space or that are difficult to access. Furthermore, the RB 65 is equipped with an electric control system, which enhances of automation and improves safety. This streamlines operation and reduces potential error sources. In addition, the rig fulfils European safety guidelines in accordance with CE/DIN EN 16228. 

Sustainability and digital features 

The rig was developed with sustainable aspects in mind: reduced noise emissions, energy efficiency, and an optimized hydraulic system contribute to resource-efficient operation. Furthermore, digital data recording enables precise monitoring of drilling processes, while remote access allows for quick error diagnosis and troubleshooting.
