摘要： Lifting tools for safe, 105 degree, off-center rotation of large, heavy objects are disclosed. A lifting tool includes a bar that can be positioned generally parallel to a centerline of the object, and first and second clamps that are rotatably or slidably coupled to first and second ends of the bar, respectively. The clamps are adapted to secure the tool to edges of the object. The tool also includes a pivot arm that is rotatably coupled to the bar, which allows the object to be lifted, rotated up to 90 degrees, moved, and then set down. The pivot arm includes first and second chain sprockets disposed along a length thereof. A second pair of chain sprockets is coupled to the second chain sprocket via a common shaft. A pair of chain segments are attached to the pivot arm, and engage each of the second pair of chain sprockets. A first end of the pivot arm can be coupled to a hoist hook, for example, via a chain that engages the first and second chain sprockets, and is coupled to the bar at a point between the clamps.

摘要： A tool for lifting and rotating an object having a center of gravity is provided. The tool includes a first rail, which is adapted to be coupled to a first end of the object, and a second rail, which is adapted to be coupled to a second end of the object. Inversion linkage is coupled to the first rail and to the second rail. The inversion linkage includes a pivot pin that automatically moves into coincidence with the center of gravity of the object when the first rail is coupled to the first end of the object and the second rail is coupled to the second end of the object.
