Description
BAT 230
Rotary drive (BAT series)
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.
Torque 230 kNm
Speed 54 U/min
Automated casing driver
Automated casing drivers allow for quick and safe connection of rotary drive and casing from the comfort of the cabin. Locking and unlocking is also possible without rotation.
Exchange of equipment
Equipment can be quickly exchanged for different methods of operation.
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.
Full displacement drilling
Full displacement drilling is a modification of continuous flight auger drilling. The drilling tool used is a smooth pipe with an auger-type starter piece.
Down-the-hole drilling
For down-the-hole drilling a hammer is mounted on the lower end of a drill rod. The hammer is activated by adding compressed air.
