The handling of deep foundation machines is particularly demanding, especially since a lot of the work is performed outwith the operator’s field of vision. The Liebherr control system has numerous useful functions and various assistance systems to simplify each piling and drilling application. They ensure quick and precise working cycles, increase safety on the jobsite and minimize wear on the machine.
All machine functions are carried out using the two joysticks. Furthermore, several movements can be made simultaneously.
The most important machine data are displayed on the control monitor with touchscreen. These vary depending on the configuration of the machine and the operation mode.
Remote control makes the assembly and disassembly of the machine easier. Navigation and alignment from various perspectives outside the operator’s cabin bring huge advantages with respect to safety.
If the attachment is fitted with a system for attachment recognition it is recorded by the control system in the carrier machine.
Changes in the leader position or swinging the uppercarriage lead to significant changes in the machine’s centre of gravity. Centres of gravity, load moments and ground pressure distribution under the crawler are calculated in real time.
The focus here is on zero accidents.
The operator can save the leader inclination. At the touch of a button, the leader can be set to the desired inclination at the piling or drilling point for each new working step. This saves time and ensures precise results.
Thanks to the latest satellite technology the operator can move the machine to the planned drilling point with pinpoint precision.
Cruise Control for all main functions: depending on the mode of operation, the operator can preselect defined values for the rope crowd system, as well as the speed and torque of the rotary drive. After activation, the drilling assistant functions similarly to a cruise control in a car: the set values are held constant by the machine control system.
The installation of cast-in-place piles using continuous flight augers, full displacement tools or double rotary drills belong to the most efficient methods in deep foundation work. Our specially designed assistant system automates the continuous drilling and extraction of the drilling tools and ensures a high-quality result.
A range of useful operator assistance systems are also available for the most common drilling method, Kelly drilling, in order to optimize the drilling cycles.
The operator is able to monitor the complete filling process of the auger from the cabin.
The amount and intensity of the left-right movements to empty the auger can be preselected. This protects both man and machine.
When lowering the Kelly drilling tool in free fall, the control system ensures that the rope is always held taut by the winches. This avoids undesired loosening of the ropes.
During Kelly drilling, one of the most difficult challenges for the operator is the correct locking of the Kelly bar. An indication on the control monitor provides the remedy.
Should the pull force of the crowd winch not be sufficient, the main winch can be connected.
Obstacle recognition enables the timely recognition of unexpected obstacles in the soil when carrying out sheet piling work. This protects both the basic machine and its attachments.
The Vibro-Assistant for Liebherr’s LRB series automates the vibro-replacement process.
Thanks to an integrated solution, the main parameters of the concrete pump can be controlled from the control panel in the operator’s cab of the deep foundation machine. This means the machine operator has control of the concreting process, which leads to safer and more efficient jobsite assignments.
Manual locking and unlocking of casing drivers is very time-consuming and laborious. Automatic casing driver provides the remedy. Operation is integrated in the control system allowing the operator to open and close the locking pins from the cabin. Power is supplied by compressed air or electro-mechanically in battery operation.
The diagnosis monitor observes the vital functions of your machine. Sensor signals, electrical control and the hydraulic pressure of valves and pumps of all main components are displayed on the diagnosis monitor:
This means errors can be quickly identified and so standing time kept to a minimum.
