KB20 - Compact drilling rig for international markets
The KB20 was one of the most versatile drilling rigs in our product range for many years and continues to impress with its wide range of applications, stable performance, and compact transport dimensions. With its powerful feed and clamping loads, flexible drilling methods, and robust construction, the rig is suitable for well drilling, geothermal energy projects, soil investigations, soundings, and general exploration work in a wide variety of soil conditions.
Due to EU emissions regulations, the KB20 can no longer be sold within the EU. However, it remains a proven and reliable machine for international markets, particularly excelling where versatility, compact dimensions, and a good power-to-handling ratio are required.
The KB20 therefore remains a solution for users outside the EU who are looking for a flexible, transport-friendly and robust drilling rig with proven technology and a wide range of applications.
