The powerful rotary drive delivers the required torque for common drilling applications such as Kelly, 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 LB carrier machine. Designed for continuous operation, the rotary drive enables especially fast drilling cycles.

    Automatic gearbox
    Four electronically adjustable speed ranges and automatic torque regulation allow for perfect adaption to the prevailing soil conditions. The drilling process is not interrupted through changing speed.
    Kelly shock absorber
    The standard Kelly shock absorber with springs and hydraulic dampers protects the material and reduces noise emission.
    Exchangeable cardan joints
    These cardan joints can be exchanged to suit the size of the casing driver.
    Exchangeable drive adapters
    Exchangeable drive adapters allow for the use of various Kelly bars.
    Integrated control system
    The rotary drive is completely integrated in the control system of the Liebherr carrier machines. This provides optimum control comfort.
    Easy transport and maintenance
    Thanks to the short and lightweight design, the rotary drive is extremely efficient as well as user-friendly in terms of transportation and maintenance.
