Abstract
A mounting tool for use in safely lifting a heavy object such as a wind tower segment. Mounting tools may be provided in a kit that includes a tool that is especially adapted for attachment to the top of the object, and a tool that is especially adapted for attachment to the bottom of the object. Both the top and bottom mounting tools include a mounting bracket for removably mounting the tool to a mounting ring on a heavy object. To accommodate different bolt patterns in mating holes in the objects, the mounting bracket has a slotted mounting hole and two generally annular mounting holes extending therethrough. These mounting holes are arrayed along a common axis. A hoist ring assembly is mounted to the mounting bracket and includes a bail adapted for swiveling and pivoting movement to define a generally hemispheric envelope.
