US 12,630,304 B2 · Strap pack support tool for helicopter maintenance

Abstract

A strap pack tool is used to support a strap pack of a helicopter to allow easier, quicker and safer maintenance of rotor hub components. This is accomplished by a cylindrical hub extending upward from a main body of the strap pack tool for engaging the blade-root end of the strap pack. Side appendages connected to the main body are provided with arms having support platforms and respective hubs for engaging the disconnected ends of rotor dampers. An interior wall located within the main body forms a cavity for engaging a raised lip of a lower flange of a strap pack housing. The tool is made of thermoplastic material with the interior of the tool being of honeycomb construction with solid I-beams providing structural support to the arms.
