A system for lifting a load via a spreader bar includes a spreader bar and a swivel lug assembly. The swivel lug assembly includes an upper swivel, a lower swivel, and a load pin extending between a pair of load pin holes in the upper swivel and the lower swivel. The upper swivel is pivotable relative to the lower swivel about the load pin. The spreader bar includes two opposing sides each having a height, and spreader bar pin holes in each of the sides. The spreader bar pin holes are located at a midpoint of the height of each of the sides. The load pin is detachably attached to the first swivel lug assembly through the pair of load pin holes in the upper swivel and the lower swivel in order to releasably attach the swivel lug assembly to the spreader bar via two opposing spreader bar pin holes.

A protective device in the form of a strap including an outermost layer having a first rigidity and a first coefficient of friction, the first coefficient of friction selected to permit a rigging line to self-center between two points when the rigging line is in contact with the outer layer and under tension and an innermost layer having a second, different lower rigidity and a second different coefficient of friction, the second different coefficient of friction selected to prevent movement of the protective device relative to an object as the rigging line self-centers. The protective device prevents damage to the coated surface, including but not limited to telegraphing of the strap onto the coated surface.

Several embodiments of an end cap are provided for use with a spreader bar system for distributing the lift force of a load across multiple points. The end cap comprises at least one lifting lug with the shackles positioned therethrough, along with at least one visual indicium for keeping a minimum of a 45 degree lift angle. Additionally, the end cap is provided with a pinch bolt system for easy assembly as well as a flat, horizontal foot plate located beneath the end cap for quick alignment. A four-point embodiment duplicates these features and positions two end caps at a 90 degree perpendicular angle atop a support plate. Additionally, a method of use is provided for pre-calculating maximum load so as to reduce the computation to a single chart.

A rope edge protector for protecting a rope as is passes over an edge during rope access and rope rescue is described. The rope edge protector comprises a body with a curved channel portion on an outer surface configured to receive at least one rope, wherein the channel portion is enclosed by a pair of side walls; a first underside surface configured for placement on a first face of an edge; and a second underside surface forming a dihedral angle with the first underside surface and configured for placement on a second face of an edge. An attachment mechanism comprising a strap connects the body to a second body and to a cam for tensioning the strap between the bodies to secure the bodies to opposing edges.

A device for supporting a becket of a travelling block features a bar whose longitudinal dimension exceeds a distance between a first pair of support legs by which one end of the becket is pivotally supported on the travelling block. The bar is abutted against the first support legs from a side thereof facing a second pair of support legs, to which the second end of the becket is coupled when the becket is closed. A sling is connected to the bar via a connection lies intermediately of the bar's ends so as to reside between the first support legs. The sling is wrapped under the becket to an opposing side of the second pair of support legs, where a lifting cable is connected to the sling. Under tension from the lifting cable, the sling snugly cradles an underside of the becket to support same during opening of the becket.

A method of lifting a rotor of a wind turbine, the rotor having a center of gravity and including a hub and first, second, and third blades projecting outwardly from the hub at locations circumferentially distributed thereabout, includes positioning first and second slings around the first and second blades, respectively, to define first and second lifting zones delineating a lifting envelope, wherein the lifting envelope encompasses the center of gravity. The method also includes lifting the rotor above a surface via the first and second slings wherein the rotor is in one of a substantially horizontal or substantially vertical orientation, with the aid of at least one of the first and second slings while continuing to fully support the rotor by the first and second slings.

A shipping container containing an unirradiated nuclear fuel assembly is lifted off the ground by operating a crane to raise a lifting tool comprising a winch. The lifting tool is connected with the shipping container by a rigging line connecting with the shipping container at a lifting point located on the shipping container between the top and bottom of the shipping container, and by winch cabling connecting with the shipping container at the top of the shipping container. The shipping container is reoriented by operating the winch to adjust the length of the winch cabling so as to rotate the shipping container about the lifting point. Shortening the winch cabling rotates the shipping container about the lifting point from a horizontal orientation to a vertical orientation, while lengthening the winch cabling rotates the shipping container about the lifting point from the vertical orientation to the horizontal orientation.
