The powerful rotary drive delivers the required torque for common drilling applications such as Kelly, continuous flight auger or full displacement drilling.

    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.

    Kelly drilling
    Kelly drilling belongs to the most common dry rotary drilling methods. Soil and rock material is conveyed to the surface discontinuously with relatively short rotary drilling tools.
    Continuous flight auger drilling
    The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger.
