Krupp GfT Tiefbautechnik hydraulic hammer drills are based on decades of experience with the development and manufacture of pneumatic and hydraulic percussion and drill mechanisms. More that 100,000 units sold are proof of Krupp's expertise in percussion technology. Each Krupp hydraulic hammer drill consists of a percussion mechanism and a rotary mechanism which can be used separately or in combination with each other. Thanks to the modular design of Krupp hammer drills, specific requirements of OEM suppliers and end users can easily be met. Of considerable advantage is the fact that when the user's requirements change, the hammer drill can be retrofitted with components such as hydraulic percussion mechanisms, reverse drilling mechanisms or rotary motors - without time-consuming conversions.
