On occasion of the international trade press conference " Pré-Intermat " on 22 January 2015 in Paris Liebherr was the only manufacturer who was awarded with two trophies of the Intermat Innovation Award. The Gold Award in the category "Equipment & Components" went to the newly developed crane operator elevator system "LIUP" , a silver trophy in the “Engineering & Systems” category was awarded to the new Liebherr Demolition Control System ( LDC) for demolition excavators.
Existing crane operator elevator systems are equipped outside the tower section, and thus require during each dismounting of the crane to dismantle. With Liebherr innovative LiUP-System, the lift is pre-installed permanently inside the tower. Only an adjustment between each tower section is required. Thus operation costs are reduced significantly. A further innovative feature is the reduction of the energy consumption by using a battery which will is charged through the downhill rides of the elevator.
Liebherr’s new developed unique LDC-system for demolition control provide the operator of Liebherr demolition excavators at any time the accurate position of the demolition attachment in order to guarantee the stability of the demolition excavator. This system allows extended reach within safe operation mode. The 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 was resolved by developing an automatic recognition of the attachment lengths and by installing angle sensors.
