INDUSTRY FUTURE Ӏ NOVEMBER 2022
j liebherr: future foundations
Innovations have been the driving force for Liebherr since 1949. Looking today what was invented over more than 70 years, it’s an incredible range of products and technologies. And there is much more to come. A lot of new products will be presented at the 2022 Bauma in Munich and the 2023 Conexpo in Las Vegas – but there are also some further things in the pipeline.
Looking into the crane world, Liebherr in Biberach is taking its tower cranes to the next level with fibre rope technology. Given that fibre rope is significantly lighter than steel rope of comparable diameter, fibre rope cranes offer a considerable increase in performance. The greater the hook heights, the more evident the rope’s effect. At present, jib head load capacities can already be increased by up to 43 percent compared to steel rope cranes. The use of fibre rope also
reduces operating costs and downtimes because the rope doesn’t require replacing as often. This is down to the fact that fibre rope is significantly more durable than its steel counterpart. On top of that, fibre rope increases safety: lubrication isn’t necessary and it is possible to see at a glance when the rope needs replacing. All this helps to ensure that Liebherr tower cranes operate even more economically in combination with their in-house manufactured high-performance drives and that the energy required for this is used efficiently. Another key future-oriented
focus for Liebherr-Werk Biberach is the digitalisation of crane operation. This includes intelligent assistance systems that actively counteract dangerous situations. New controls and user interfaces will make crane
operation even more responsive and intuitive. In addition, crane operators will no longer necessarily have to climb into their cabs in future. The LiReCon teleoperation unit for tower cranes will one day make it possible to control cranes from the ground. Digital services will enable crane deployment planning and other processes to be even more efficient.
BATTERY POWER Jumping to the world of multi- purpose crawler cranes and special deep foundation, products that are manufactured from Liebherr- Werk Nenzing GmbH. In 2019 the engineers from Nenzing presented the worlds-first battery powered drilling rig. Only a year later, Liebherr revolutionized the crane industry with the world’s first battery powered crawler crane, the LR 1250.1 unplugged. The electro-hydraulic drive of the new cranes has the same performance specifications as the conventional version. Both versions are operated in the same way, which is especially practical if the crane driver has to often change between machines in one fleet. An outstanding feature of the
battery-powered unplugged units is zero emission. They do not produce any exhaust fumes and are extremely quiet. This strikes

the right note especially in noise- sensitive regions and finds favour with construction site personnel and residents. Whether London, Paris or Oslo - the concept has already been successfully applied in these metropoles. The battery is charged using
a conventional jobsite electric supply. Operation can continue as normal while charging. In order to change to battery operation, you just need to pull out the plug, therefore: unplugged. Whether attached to the electric supply or not, the performance and range of application remains unchanged. The designers of the crane laid great emphasis on the safety concept. As with all crawler cranes from Liebherr-Werk Nenzing GmbH, the new battery-operated models are also available with all proven assistance systems. In the world of mobile and crawler cranes, the products of the Ehingen plant, first of all the full fleet readiness for using HVO has to be mentioned. Since September 2021, all cranes leaving the factory and the factory internal traffic is using HVO instead of diesel, thus reducing the CO2 emissions in operation up to 90% compared with the use of fossil diesel. And all crane companies can switch to HVO immediately, saving tons of CO2 emissions worldwide within an instant – without any refurbishing or changes on the crane or drive system itself. All Liebherr cranes are 100 % ready for HVO. In April 2021, the first hybrid
crane from Ehingen was presented, delivery starts in 2023. The accelerating climate revolution demands drive concepts which reduce emissions of greenhouse gases. That is why our new LTC 1050-3.1E compact crane has an electric motor in addition to its conventional power unit. This enables crane movements to be powered electrically as an f
