The powerful rotary drive delivers the required torque for common single-pass applications such as continuous flight auger or full displacement drilling. Considerable advantages are the automatic torque regulation as well as four electronically adjustable speed ranges. The rotary drive is powered by the on-board hydraulics of the LRH carrier machine. Designed for continuous operation, the rotary drive enables especially fast drilling cycles.
