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.

A chain hoist (10) having an improved chain guide (12) for a link chain (14). The chain guide (12) has a channel (36) with a cross-shaped cross section, through which the link chain (14) extends. An end surface (26) of the chain guide (12) extends away from a mouth opening (28) of the channel (36). The channel (36) establishes a through-passage direction (D) which widens in the direction of the end surface (26), and a protrusion (30) is formed on the end surface (26) around the mouth opening (28) of the channel (36).

An adaptor for a power tool having a hardened cylindrical body having a tool receiving end and a lifting device engaging end. The tool receiving end which has, a square hole axially extending within the cylindrical body, for connecting between an output head of an impact rotary tool, and a lifting device receiving end. The device is used to improve speed in lifting procedures with various lifting devices.

An apparatus for operating a hand chain of a hand chain hoist. A housing forms a void through which a hand chain of the hand chain hoist moves in either a lifting direction or a lowering direction, to lift or lower, respectively, a load corresponding to the hand chain hoist. A sprocket or two pulleys are movably mounted within the housing. A drive, such as a right angle drill, operably moves the sprocket and/or the pulley and thus moves the hand chain, selectively, in the lifting direction or the lowering direction. A line, a cord and/or another suitable structural element connects the housing to an overhead structure. Another line, cord and/or other suitable structural element connects or holds the housing with respect to a ground surface or another fixed structural element, and an operator can use this line, which can be adjustable, to tighten and hold the overall chain hoist drive time of this invention.

A hoisting system includes an antenna that includes a main mast. A support is provided and the support may be coupled to a crane thereby facilitating the support to be elevated onto the antenna. The support engages the main mast such that the support is removably coupled to the antenna. A pulley is coupled to the support and a line is extended through the pulley. The line may have an object coupled thereto. The line is selectively urged through the pulley such that the line urges the object upwardly on the main mast.
