Packing for Demag AC1200

The packing 440 979 40 acts as a sealing component within the hydraulic or pneumatic systems of the Demag AC1200 crane. Its primary function is to create a tight barrier between mating surfaces to prevent the leakage of hydraulic oil or compressed air while protecting internal components from external contaminants. Maintaining this seal is necessary for the proper operation of hydraulic cylinders, valves, and pumps that control the crane's boom and load movements.

This component is compatible with the Demag AC1200 crane. It is designed to meet the specific engineering dimensions required for these systems. Proper installation ensures the integrity of the hydraulic or pneumatic circuit, which helps maintain system pressure and prevents energy loss during operation.

In heavy machinery, packing components are used to maintain fluid or gas containment within pressurized systems. They are installed between stationary or moving parts to ensure that the system operates within its design parameters. Regular inspection of these seals is standard practice to identify signs of wear or leakage, which can lead to a loss of system efficiency or pressure drops in critical crane functions.
