2024 Liebherr Rotary drive BAT Series BAT 550

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.

Features may include:

• 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.

• 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.

• These cardan joints can be exchanged to suit the size of the casing driver.

• Exchangeable drive adapters allow for the use of various Kelly bars.

• The rotary drive is completely integrated in the control system of the Liebherr carrier machines. This provides optimum control comfort.

• Thanks to the short and lightweight design, the rotary drive is extremely efficient as well as user-friendly in terms of transportation and maintenance.
