TOOL FOR THE REMOVAL AND INSTALLATION OF POLAR END CAPS OF FRESHWATER TANKS ON BOARD AIRPLANES IN THE BUILT-IN STATE

摘要

This relates to a tool for removing and installing polar caps of freshwater tanks on board airplanes without first removing or displacing the tanks or a compartment. The tool encompasses a key disk, a coupling and a lever. One end of the lever is joined in a torque-proof manner with the key disk via the coupling. The key disk can be joined in a torque-proof manner with the end cap, and the other end of the lever exhibits a key connection that is set up to be joined with a torque wrench. The length of the lever is here dimensioned and the key connection is designed in such a way that obstacles in the environment of the polar end caps do not block the tool while it is in use.
