Abstract: A portable hoist system has an adjustable support strut mechanism, allowing for compact storage and portability, with the entire assembly retained as one unit. In one embodiment the support strut mechanism, which is connected on one end to a boom and at another end to a bracket, is foldable and adjustable using an adjustment pin and holes along the two-piece support strut mechanism. In one preferred form of the invention a winch of the hoist system is field-adjustable as to position on the hoist's boom, to overcome problems of space constraints.

Abstract: A portable hoist apparatus includes a boom secured to a frame or body, which includes, at a side opposite the boom, a cylindrical mounting collar, on a vertical axis, can be slipped over a cylindrical pivot tube that in turn is connected to any of a number of different base mounting structures that are configured to be attached to various stable anchoring structures, such as on buildings, decks, posts, vehicles, floors and many other structures.

Abstract: Portable cranes for wind turbines are provided. In one embodiment, a crane includes a boom, a support shaft connected to the boom, and a plurality of interchangeable mount assemblies. Each of the plurality of mount assemblies is removably connectable to the support shaft and mountable to a wind turbine component. The crane is mountable to at least two different wind turbine components. In another embodiment, a crane includes a boom, a support shaft connected to the boom, and means for mounting the crane to at least one uptower wind turbine component and at least one downtower wind turbine component.

Abstract: The system and method of the present invention provide support for a holster mounting into which the vertical support of a portable hoist assembly is inserted. Disclosed is a saddle mount for the holster mounting usable on the atop of a wall, a waste receptacle or a beam. Also disclosed is a floor supported base and cart assembly for the holster mounting.

Abstract: A foldable portable hoist system includes a foldable portable hoist assembly and a mounting base. The foldable portable hoist assembly includes a substantially vertical support, an upper support arm, and a diagonal brace assembly. Hinged attachment of slidable collars on either end of the diagonal brace enables the foldable portable hoist assembly to be folded up for ease of transport and storage.
