New system “Liebherr Demolition Control”
23/02/2015
This system, developed by Liebherr-France SAS, won the Innovation Silver Award from the trade fair INTERMAT 2015.
The “Liebherr Demolition Control, LDC” allows at any time to give the operator the position of the demolition attachment and to guarantee the stability of the demolition excavator.
By means of angle sensors mounted on the excavator and with an automatic recognition of the attachment lengths, the system informs permanently about the position of the attachment (in cm).
Knowing the weight of the tool the excavator can operate in complete safety in its working area.
For Liebherr-France SAS, the main challenge was to find a solution to integrate this LDC system into the electronics of the excavator and to simplify the manipulations for the operator.
This idea was to propose an automatic recognition of the attachment lengths, to install angle sensors to know the position of the equipment and to integrate into the display of the excavator the tools types with their weight.
To optimize the performances of the excavator, an extended reach with limitation of rotation has also been developed.
Due to the integration of the system LDC to the electronics of the excavator the customer needs no more specific components which allowed him to earn money at the purchase and the maintenance becomes easier.
The extended reach allows the customer to reach additional working area, which gives him productivity gain on his jobsite.
This new LDC eliminates a possible human error, which could affect the stability of the machine.
A tactile color display enables to visualize the animation of the position of the attachment in real time and to inform the driver of the authorized movements.
A display of the position (flatness) of the machine is also given to the driver.
The increase of the working zone allowed by the extended reach gives the possibility to realize demolition works with machines of smaller size, which reduced consumptions during work and during transport of the machine.
