The closing plug, identified by part number 171 260 40, serves as a component for sealing openings within the systems of the Demag AC80-1 crane. It is used to close inspection, filling, drainage, or access ports located on housings, reservoirs, and hydraulic or lubrication circuits. By providing a secure closure, the component prevents fluid leakage and blocks the entry of external contaminants such as dust, dirt, and moisture, which helps maintain the internal integrity of the machinery systems.
This component is compatible with the Demag AC80-1 crane model. Proper installation of this plug is necessary to maintain the operational efficiency of the crane systems where it is applied. It is also known as a VerschluBschraube plug in technical documentation for these machines.
In heavy machinery, plugs of this type are used to seal ports that are not currently in use or that require occasional access for maintenance tasks. They are critical for ensuring that pressurized systems or fluid reservoirs remain isolated from the environment, thereby protecting sensitive mechanical and hydraulic components from premature wear caused by debris or fluid loss.
