This seal kit includes a collection of sealing components required to service hydraulic cylinders, valves, and pumps within the Demag AC80-1 mobile crane. By replacing worn seals, this kit restores the internal and external sealing integrity of hydraulic assemblies, which is necessary to maintain system pressure and prevent fluid leakage during crane operations such as lifting, extension, and stabilization.
The component is compatible with the Demag AC80-1 model. It typically contains a variety of O-rings, piston seals, rod seals, and wipers required for a complete overhaul of the specific hydraulic assembly. Proper installation of these components ensures the hydraulic system operates within its design parameters.
Seal kits serve as a maintenance solution for hydraulic systems by replacing the interfaces that contain pressurized oil. In heavy machinery, these kits are used to address leaks or pressure drops caused by degraded seals. By renewing these contact points, the hydraulic system can maintain the necessary force and movement control required for safe machine operation.
