• Durable
  Our hydraulic pumps and motors for building construction and civil engineering are distinguished by reliability and durability.
• Diverse
  Liebherr hydraulics can be employed in many different ways. The applications range from drilling rigs to wheeled excavators and crawler cranes.

Specifically designed products

• Axial piston pumps DPVP
  Liebherr pumps of the DPVP series are used predominantly in excavators. An upstream spur gearbox facilitates downspeeding to reduce exhaust gas emissions.
• DPVG axial piston pump
  The DPVG variable displacement pumps for the closed circuit are suitable for equipment with frequent load changes, e.g. wheeled excavators or wheel loaders. The adjustability of the pump makes load-dependent stability of the rotary unit possible. The hydrostatic cradle bearing has a positive effect on the service life and reliability of the components.
• Axial piston motor CMVE
  The axial piston motors of the CMVE series are orientated around use in various crawler vehicles. The compact design results in an optimum price to weight ratio.

• Compact
  Electric motors of the KGF and KDF series are distinguished by their compactness and sturdy design. They are ideally suited for electric-powered cranes.
• Powerful
  The layout of the machines, with outputs ranging from 7.5 to 650kW, allows for requirements in field weakening. This ensures the best possible performance with loads at the end of the crane boom.
• Perfect harmonisation
  The optimum harmonisation with other components, such as inverters or gearboxes, enables fast commissioning.
• Durable
  High availability during operation, long availability of spare parts and fast service assure an economic service life of the end equipment in the long term.

• Electric machines: Products and applications

• Individually adapted
  The model series and project-specific products feature surface protection tailored to customers' individual needs. The protection comprises priming, painting or coating.
• Customer-specific services
  The service from Liebherr is always orientated around the requirements and deployment situations of our customers. Thanks to comprehensive certifications and registrations of Liebherr service technicians, a whole range of different deployment scenarios are possible.

Specifically designed products

• Slewing drives
  Slewing drives from Liebherr cover a broad area of application and are used, for example, in slewing mechanisms from construction cranes and mobile cranes or concrete pumps. They achieve optimum results here.
• Swivelling drive
  The drives are suitable for swivelling mechanisms in excavators for adjustment of the uppercarriage. Furthermore, they are also used in deep foundation machines and material handling equipment.
• Travel drives
  In building construction and civil engineering there are two different designs of travel drive. The compact, coaxial units are ideally suited for excavators of different size categories. The travel drive with upstream spur gearbox makes higher ground clearance of the equipment possible. It is used for this reason in crawler dozers and crawler loaders.
• Planetary plug-in gearbox
  The planetary plug-in gearboxes are suitable for installation in rope winches. They are employed predominantly in shredders.
• Splitter box
  The sturdy gearboxes prove their worth above all in mobile and crawler excavators, duty-cycle crawler cranes, crawler tractors, crawler loaders, pipe layers, wheel loaders, deep foundation machines as well as material handlers.
• Customised gearboxes
  Liebherr offers project-specific manufacture of components. The applications range from drilling rigs for the kelly bar to cyclone drives for stirring mechanisms in stationary mixing plant.
• Rope winches
  Rope winches from Liebherr have a compact design, well-engineered safety equipment and precision rope guides. They ensure minimum rope wear and therefore offer a high level of availability. The rope winches are used as hoisting winches for main or auxiliary lifting by cranes or deep foundation machines. They also impress as boom and luffing winches on duty-cycle crawler cranes or in crane trolley mechanisms.

• Gearboxes and rope winches: Products and applications

• Diverse
  The application possibilities range of large diameter slewing bearings reach from crawler cranes to road transport and drilling rigs. Either ball bearing slewing rings or three row roller bearing slewing rings are used.
• Powerful
  On mobile cranes registered for road use, every kilogram of weight counts. With special roller bearings, very high support loads can be realised in a small installation space, thereby facilitating an ideal power to weight ratio.

• Robust and durable
  Hydraulic cylinders from Liebherr are particularly hard wearing thanks to the use of robust materials. Their durability has been tried and tested for years in excavators and other earthmoving equipment.
• Flexible
  The cylinder layout, specially developed for excavators, guarantees high flexibility for our customers. The product program from Liebherr also comprises cylinders for a whole range of different attachments, e.g. scrap shears, grabbers or clamping devices.
• Secure and stable
  In cranes and other equipment registered for road use, so-called lightweight cylinders are often used. Special geometries and the use of very strong materials provides a high level of stability and safety even with thin-walled cylinder tubes and hollow piston rods.
• Low friction
  With low friction sealing systems, our cylinders ensure very smooth running and high energy efficiency of the hydraulic system.
