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 45 or LRB 355 carrier machine.

  • Torque - 450 kNm

  • Speed - 40 U/min

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.
Rotary drive with selective Kelly shock absorber
The latest version of the rotary drive has a newly developed Kelly shock absorber, which allows the damping strength to be adapted depending on the respective weight of the Kelly bar.
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.
