Undercarriage

The robust universal machine for a wide variety of applications:

• Kelly drilling

• Auger drilling

The rigid leader absorbs high torque and is fitted with a rope crowd system for high pull forces.

• Full displacement drilling

• Double rotary drilling

All winches are mounted on the leader, which provides

a direct view of the main winch from the operator‘s cab. The solid undercarriage offers excellent stability and low ground bearing pressure.

The rotary drive of the BAT series combines exceptional

torque with optimum operating comfort. The uppercarriage with its small swing radius enables operation in restricted space.

The powerful Liebherr diesel engine is low in emission and

economical through SCR technology. Parallel kinematics with a large working area allow to fold the leader back and, as an option, forward.

Liebherr Kelly bars feature strongly overlapping elements resulting in less wear.

Precise and robust Liebherr casings and drilling tools provide excellent drilling performance.

Sophisticated solutions provide safe operation and maintenance of the machine.

• Cab design for optimum visibility

• Acoustic and optic warning

• Walkways on the uppercarriage

• Safety rails on top of the uppercarriage

• Rear and side view cameras etc.

Technical description

Engine

Power rating according to ISO 9249, 505 kW (677 hp) at 1700 rpm Engine type Liebherr D 9508 A7 SCR Fuel tank 1000 l capacity with continuous level

indicator and reserve warning

Engine complies with NRMM exhaust certication EPA/CARB Tier 4i and 97/68 EC Stage III B.

Hydraulic system

The main pumps are operated by a distributor gearbox. Axial piston displacement pumps work in open circuits supplying oil only when

needed (ow control on demand).

The hydraulic pressure peaks are absorbed by the integrated automatic pressure compensation, which relieves the pump and saves fuel.

Pumps for working tools 2x 485 l/min Separate pump for kinematics 215 l/min Hydraulic oil tank 1400 l Max. working pressure 350 bar

The cleaning of the hydraulic oils occurs via an electronically monitored pressure and return lter. Any clogging is shown on the display in the cab. The use of synthetic environmentally friendly oil is also possible.

Crawlers

Control

The control system – developed and manufactured by Liebherr – is

designed to withstand extreme temperatures and the many heavy–

duty construction tasks for which this machine has been designed.

Complete machine operating data are displayed on a high resolution

monitor screen. A GSM/GPRS telematics module allows for remote

inquiry of machine data and operational conditions. To ensure clarity

of the information on display, different levels of data are shown in

enlarged lettering and symbols.

Control and monitoring of the sensors are also handled by this high

technology system. Error indications are automatically displayed on

the monitor in clear text. The machine is equipped with proportional

control for all movements, which can be carried out simultaneously.

Two joysticks are required for operation. Pedal control can be

changed to hand control.

a spring–loaded, multi–disc holding brake. All line pull values are

effective values. The efciency factor of approx. 25% has already

External sensors

Depending on the application the recorded and processed data are displayed on the PDE® touchscreen in the operator‘s cab, e.g. in the form

of an online cast-in-place pile.

At the same time the PDE start and stop recordings. A recording of every start-stop cycle carried out in the PDE

is operated using this touchscreen. The operator can enter various details (e.g. jobsite name, pile number, etc.) and

is established on a CompactFlash memor y card.

The PDE® can be con gured in a number of ways, e.g. for the connection of external sensors, for the generation of a simple protocol as graphic  le and/or for a printout directly in the operator‘s cab.

Process data reporting - PDR (additional equipment)

Comprehensive data evaluation and generation of reports on a PC is possible using the software PDR.

Recordings management - The recordings generated by the PDE® system can be imported and managed

in PDR. The data can be impor ted directly from the CompactFlash card or via the Liebherr telematics system LiDAT. Certain recordings, e.g. for a particular day or jobsite, can be found using  lter functions.

Viewing data - The data in each record is displayed tabularly. Combining several recordings provides

results, for example, regarding the total concrete consumption or the average depth. Furthermore, a diagram

editor is available for quick analysis.

Generating reports - A vital element of PDR is the repor t generator, which allows for the generation of individual reports. These can be printed out directly or stored as pdf  les. In the process the size, colour, line thickness or even the desired logo can be con gured. Moreover, the repor ts can be displayed in different languages, e.g. in English and in the national language.
