![]() The stopping positions of LiUP are monitored by three limit switches, while a clasp break reacts if the elevator starts to travel too fast. There are no additional supply lines such as cables or ropes and autarchic power supply is provided in the event of a power failure by the lithium-ion battery drive technology. The lift, exhibited at TOC Europe, can also be used by service engineers carrying out maintenance work. LiUP’s battery is automatically charged when it is in its parked position and the elevator can achieve approximately 40% energy recovery as it descends.Ĭapable of transporting up to two people or a payload of 200kg, LiUP is designed to transport crane operators in a safe and efficient way, saving time and energy compared to climbing up stairs. Liebherr cranes are not only used successfully for the construction of offshore wind turbines, but also on oil and gas platforms, for offshore construction, pipe-laying or subsea operations down to 3,600 m below sea level.Liebherr has launched a crane driver elevator with drive technology powered by an electric motor with lithium-ion battery and the ability to recover up to 40% of energy. Thereby the Group’s offshore portfolio meets challenging requirements, such as the provision of diesel or electrical drive units, explosion protected cranes and cranes for ambient temperatures between +40 ☌ and -50 ☌. Heavy duty cranes for offshore applications are able to lift up to 5,000 t and reach a lifting height of 180 m above deck. In tandem lift mode, two LHM 800 mobile harbour cranes can lift up to 616 t. The tandem lift-assist system Sycratronic is often used for this purpose. Liebherr mobile harbor cranes handle rotor blades, generators, nacelles and monopiles for the erection of wind farms onshore and offshore. The Liebherr Group also offers innovative solutions for the loading and erection of wind turbines at offshore locations. Advantages are reduced space required by the crane, the ability to work despite high wind speeds and sensitive lifting of loads using Micromove. They are mounted on the wind turbine and are configured in a way that the necessary lifting height can be reached by guying the crane to the mast at one point only. This is especially economical, because machine and equipment have to be mounted only once.įor erecting wind turbines with a hub height of 110 m or more in low-wind areas, Liebherr also offers specially developed tower cranes with lifting capacities of up to 125 t. The Liebherr Group keeps pace with the development of larger and more efficient turbines as well as the increasing hub heights by offering cranes with optimized performance and new jib systems, reaching higher lifting capacities.Ĭranes on narrow crawler travel gears especially developed for the construction of wind farms can move on the narrow tracks from one unit to the next in full setup condition, that is including jib and full ballast. ![]() As well as telescopic mobile cranes, Liebherr also provides lattice boom mobile cranes and crawler cranes to erect wind power systems, in a variety of performance classes, specifically matched to meet the needs of the wind power industry. For decades, they have also been proving their value in the construction of wind farms. With their innovative technology, high quality, profitability and longevity, mobile and crawler cranes from Liebherr own a leading position in the world market. The product portfolio comprises components for turbines from 800 kW up to solutions for multi-megawatt offshore turbines. ![]() In the wind industry, Liebherr collaborates with nearly all leading turbine manufacturers, having equipped numerous wind turbines with its own components. One of the major elements of cooperation with customers from all over the world is application-specific engineering to perfectly adapt each of the components. The portfolio also includes compact full-scale converter solutions for wind turbines with a capacity from 2 to 5 MW. ![]() For rotor blade adjustment, Liebherr offers moment bearings in two main designs: as double-row tapered roller bearings or triple-row roller bearing slewing rings. Offering slewing bearings, slewing drives, electric machines, frequency converters and hydraulic cylinders, Liebherr is the only manufacturer worldwide that provides not only single components, but also entire systems for electromechanical and hydraulic pitch and yaw adjustment in wind turbines. On the other hand, the company’s mobile, crawler, offshore and tower cranes, for example, are used for erecting wind turbines and constructing wind farms. ![]() Liebherr is a powerful partner for the wind industry and offers convincing solutions for a wide range of requirements: On the one hand, components manufactured by Liebherr are installed directly into wind turbines. ![]()
