| 20120061982 | HOIST RING ASSEMBLY AND METHOD - A hoist ring assembly includes an anchor subassembly with bushing, retainer and threaded fastener elements, and a loop subassembly with a lifting loop and pair of pin elements. The assembly is adapted such that the lifting loop is rotatable through a 360-degree angle about a major axis, and pivotable through at least 180-degree angle about a minor axis. The assembly can be rapidly assembled or disassembled, and incorporates one or more components which may be substantially fabricated by way of forging operation, particularly the retainer member. | 03-15-2012 |
| 20110037279 | Tower Erection Lift Kit Tools - 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. The bail is mounted for swiveling about a swiveling axis. The swiveling axis extends approximately between the two generally annular mounting holes and the slotted mounting hole. At least two fastener elements are adapted to project fasteningly through the mounting holes. The fastener elements may be straight or stepped as may be necessary to accommodate various mating hole sizes in the heavy objects. | 02-17-2011 |
| 20100278613 | FIXED EYEBOLT ASSEMBLY AND INVENTORY THEREOF - An eyebolt assembly is provided in which a skirt member is reinforced by radially projecting diametrically extending ribs. A fixed lifting eye projects from one side of the skirt, and a mounting stud projects from the opposite side. The mounting stud is double threaded with one thread being adapted to mate with a threaded bore in the body of the eyebolt assembly, and the other thread being matched to a threaded bore in a load. The same eyebolt body can be employed with a plurality of different mounting studs, which simplifies inventorying eyebolt assemblies to meet all of the different threaded bores that may occur in different loads. Only the mounting studs need to be threaded to match the loads. The skirts are provided with striking faces so that they can be tightened and loosened by striking them with a hammer. | 11-04-2010 |
