Hydraulic cylinders for mobile applications
Liebherr sets standards in mobility: With the sturdy hydraulic cylinders for mobile applications, our customers profit from sound product knowledge and innovative solutions. Flexibility is guaranteed thanks to hydraulic cylinder series that are specially designed for mobile applications in the pressure range of up to 260 and 380 bar.
Product portfolio - Hydraulic cylinders for mobile applications
The robust products deployed in the 380 bar series-production range are built for handling dynamic loads. As hoist, stick and bucket cylinders, they move the equipment on wheeled excavators.
Boom and luffing cylinder
As a boom or luffing cylinder for concrete pumps or mobile cranes, this type of hoist cylinder handles the movement of the boom or crane arm.
Swing axle cylinder
The swing axle cylinder from Liebherr with one-sided action is used to fix the drive axle on wheeled excavators, for example.
Pull cylinders fulfil safety-relevant functions when tensioning mobile crane ropes, among other things. Liebherr therefore uses high strength materials in their manufacture.
The single or double-acting telescopic cylinders are suitable, along with other possibilities, for erecting the cross members of a crawler crane. When retracted, the telescopic cylinders impress with their compactness. The rams eject in multiple stages allowing a large lift to be realised.
Ballast cylinders adopt safety-relevant functions, e.g. taking up ballast weights in mobile cranes. Liebherr therefore relies on high strength materials during production.
Synchronised cylinders are used to adjust the horizontal position in a whole range of different applications, e.g. in the maritime or earthmoving sector. For the maritime sector, the special ram coating offers optimal protection against corrosion.
On the simple plunger cylinder, the ram itself acts as a piston. These can be used, for example, to raise the cab chassis on material handling equipment.
Support cylinders are distinguished by their lightweight design. Nevertheless, they assure the highest stability. Support functions are required in numerous applications in the mobile construction machine sector for example the concrete pump.
