End cap and spreader bar system and method for sizing same
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 includes a receptacle shaped to receive the spreader bar. The receptacle comprises an outer end and a pinch bolt located on an outer surface of the receptacle. A load plate abuts the outer end of the receptacle, and is reinforced by a brace. A lifting lug extends from the load plate and has at least a first aperture. The aperture is shaped to receive a corresponding shackle that is configured to connect to a sling for lifting the spreader bar. A visual indicator on a surface of the lifting lug and positioned between the first aperture and the load plate defines a predetermined minimum angle between the spreader bar and the sling when the spreader bar is lifted via the sling.

Net and a method of making the same
A net includes at least two ropes (2, 4), at least one mesh, wherein at least one corner of a mesh is formed by a knot (15) formed by two of the ropes (2, 4). The knot includes a first and a second opening (6, 8) in the first rope (2) through which the second rope (4) passes, and a first opening (10) in the second rope (4) through which the first rope (2) passes. A part of the first rope (2) is being positioned in the first opening (10) in the second rope (4) being in between the first and second opening (6, 8) of the first rope (2).
Cargo vessel lid lifting system
An apparatus including a base, a guide arm pivotable relative to the base, the guide arm movable between a raised position and a lowered position. A tension linkage having a distal end extending away from the base, the tension linkage supported by the guide arm when the arm is in the raised position. A tension linkage guide disposed on the guide arm, the tension linkage guide movable along the tension linkage as the guide arm moves between raised and lowered positions. A lid hook connected to the distal end of the tension linkage. When the lid hook is engaged with a cargo vessel lid, the tension linkage forms a first tension angle and a second tension angle when the guide arm is in the raised position and the lowered position respectively, the second tension angle being less than the first tension angle.

Hoist cage assembly
A hoist cage assembly for lifting a pallet with a crane includes a cage that has a bottom end that is open for positioning around a pallet of material. The cage has a plurality of bar openings each extending through the cage. A plurality of bars is each of the bars is slidable through a respective pair of the bar openings to extend through the pallet when the cage is lowered over the pallet. Each of the bars rests on the cage when the cage is lifted to lift the pallet when the cage is lifted. A plurality of sleeves is each of the sleeves is coupled to the cage and the sleeves are strategically arranged on the cage thereby facilitating each of the bars to be slidably stored in the plurality of sleeves.
RIGGING BASKET
A rigging assembly has no loose parts that an up-rigger may drop. The rigging assembly includes a length of steel cable terminating in a loop at each end. One loop extends through an oblong master link, while the other loop extends through a swivel hook. The ground-rigger can attach the hook of a hoist's chain to the master link on the ground. The ground-rigger can then tie the up-rigger's rope onto the master link. The up-rigger then pulls the rigging assembly and the hoist's chain up to the beam, leaving the master link and chain under the beam. Then the up-rigger grabs the hook end of the rigging basket assembly, bends it over the beam, and attaches the swivel hook end to the master link, thus creating a loop around the beam to support the hoist's chain and load, which is known in the industry as creating a basket.

SOCKET ASSEMBLY
A socket assembly includes a socket. The socket defines a first interior space. The socket includes a first frame and a second frame disposed opposite to the first frame. The first frame is coupled with the second frame using at least one fastening member. The socket assembly includes a locking member disposed within the first interior space of the socket. The locking member includes a first portion and a second portion. The first and second portions define a second interior space for holding a rope.
