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.

Liebherr is increasing the overall service life of its Fibre ropes from 14 to 16 years, with the decisive period of use rising to up to 12 years. This is based on multi-year ageing trials on test rigs and analyses of ropes already in field. The new ruling applies automatically to all new ropes and those already in the field. This step forms part of Liebherr's ongoing path towards establishing Fibre technology as the new standard in the tower crane market.

Five questions that show why planning a tower crane deployment is more complex than you might think
On spectacular construction sites, it's the structures that take the spotlight. But building bridges, tunnels or skyscrapers in the first place often demands equally extraordinary crane concepts. From the Sagrada Família in Barcelona to the Fehmarnbelt Tunnel in Denmark, Liebherr supports demanding tower crane deployments worldwide. Max Widder, Head of Project Planning at Tower Crane Solutions, gives insight into the challenges behind some of the most complex crane projects in the world.

At InnoTrans 2026, Liebherr will unveil its new railroad excavator for the first time: the RE 22 M Litronic. This model expands the existing range to include a machine in the 22-tonne class with hydrostatic rail-wheel drive and is the successor to the A 922 Rail and A 924 Rail. The machine combines tried-and-tested components from the A 922 Rail with a newly developed undercarriage and a new operator's cab.
