KB25 - High-performance drilling rig for larger diameters and deeper drilling
The KB25 is a robust, mid-range crawler drill rig designed for users who require larger drilling diameters, greater feed force, and deeper drilling distances without having to upgrade to the heaviest machines. With its stable hydraulics, powerful feed system, and wide range of drilling methods, the KB25 covers a broad spectrum of applications – from well drilling and geothermal energy to soil investigations, soundings, and geological exploration.
Compared to the KB21, the KB25 offers greater work reserve, a more stable platform, and higher travel capacities, while remaining manageable in terms of transport, handling, and operating costs. The machine is particularly suitable for projects requiring reliable performance, reproducible work processes, and increased durability – for example, with larger drilling diameters, greater extraction depths, or varying soil profiles.
The KB25 thus closes the gap between the compact KB series drilling rigs and the heavy large-scale systems, offering a powerful yet still mobile solution for more demanding drilling operations.
