ABSTRACT:
A flap handling tool which eliminates rigid hookup at fixed points and permits ease of location of lift points, disburses the lifting load over a broad area and permits an evaluation of proper position of loading strap anchor points during lift and excessive stresses. A flap handling tool is provided which includes a flap engaging fixture for receiving the trailing edge of a flap and a flexible strap assembly designed to be twice the proof load or twice the working load. The flap handling tool may be used in multi-lift point applications. Two such tools distributes the lifting factor in four places doing away with the normal three point solid lift. The hoisting structure, i.e. overhead crane and cables are attached to a lug on the engaging fixture and a D-ring sewn into the strap. As an overhead crane is directed up, the operator can visually observe any stretch on nylon strap permitting early detection of excessive weight, misalignment or mispositioning conditions thereby providing a greater margin for finding and correcting error. Tension adjustment is included on the engaging fixture to eliminate slippage and insure a tight connection. Those portions of the flap engaging fixture which actually are in contact with the flap surface have a resilient padding to avoid damage to the control surface.
