Abstract
Lifting tools for safe, 90 degree 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 a pair of idler pulleys disposed along a length thereof. A first end of the pivot arm can be coupled to a hoist hook, for example, via a cable that wraps partially around the pulleys and is coupled to the bar at a point between the clamps.
