Heavy duty cylinders

The working conditions for mining equipment are particularly demanding for hydraulic cylinders. Liebherr heavy duty cylinders are fitted with application-specific sealing systems to withstand the conditions. The piston rod is manufactured from a forged component and is coated for the specific application. The design of the heavy duty cylinders includes a life-cycle management, which extends the service life of the hydraulic cylinder by enabling optional reworking of its individual components. High-quality cylinder materials are used to optimise the heavy duty cylinders for dynamic applications.
