BAT 300 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 30 carrier machine.
Torque 297 kNm
Speed 43 U/min

Features

Easy transport and maintenance

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.

Integrated control system

Integrated control system

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

Exchangeable drive adapters

Exchangeable drive adapters

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

Exchangeable cardan joints

Exchangeable cardan joints

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

Rotary drive with selective Kelly shock absorber

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. more

Automatic gearbox

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.

Accessories

Casing oscillators

Casing oscillators

If required, Liebherr piling and rotary drilling rigs can be equipped with a number of casing oscillators which are operated via the machine’s on-board hydraulics. No external power pack is required which leads to significant cost savings.

Electronic evaluation of working processes

Electronic evaluation of working processes

With the PDE process data recording system machine data is recorded during the working process. With PDR these data can be managed, displayed tabularly or graphically, and analyzed. In combination with the telematics system LiDAT these reports can be easily generated from the office. more

Fleet management and teleservice

Fleet management and teleservice

The data transmission and positioning system “LiDAT” provides important information on the operation of the machine. With these data the operation becomes more efficient. Various additional modules allow machine data reporting or access through service engineers via teleservice. more

Low-head leader system

Low-head leader system

The automatic casing drive adapter with remote control for locking and unlocking the casing pipe offers significant advantages in terms of safety as no personnel is exposed to the hazardous area. In addition faster production cycles can be achieved.

Automatic engine stop

Automatic engine stop

The machine can optionally be equipped with an automatic engine stop control. Thanks to this feature it automatically switches off during longer work breaks after evaluating several machine parameters. This is fuel saving and environmentally friendly.

Eco silent mode

Eco silent mode

With the eco silent mode the engine speed can be reduced to a predefined, required level. With this feature a notable reduction in diesel consumption can be achieved without any impact on operational output. Noise emissions are thus also lowered.

Low-head leader system

Low-head leader system

At jobsite conditions with limited heights, such as under bridges or below power lines, the rig can be equipped with a shortened “low-head” leader.

Kelly Visualization

Kelly Visualization

Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly Visualization system.

Remote control

Remote control

The remote control simplifies the loading process for transportation as well as the assembly of the machine.

Drilling Assistant

Drilling Assistant

During continuous flight auger drilling the concreting process is automated thanks to the Drilling Assistant.

Ground Pressure Visualization

Ground Pressure Visualization

The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite.

Applications

Dry soil mixing

Dry soil mixing

For dry mixing a binding agent is introduced into the ground as powder. more

Wet soil mixing

Wet soil mixing

For wet mixing a self-hardening suspension is introduced into the ground. more

Down-the-hole drilling

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. more

Full displacement drilling

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. more

Continuous flight auger drilling

Continuous flight auger drilling

The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger. more

Kelly drilling

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. more
