The tiedown device includes a tubular body member having a plurality of slots opening at one end of the body member so as to separate and define a plurality of cantilevered segments each capable of being forcibly urged outwardly into gripping relationship with a surrounding structure, such as a concrete floor slab, by a wedge member within the body member and having an exterior surface in engagement with the interior surface of the cantilevered segments. A top insert is positioned within the body member and has an end portion with one surface thereof in engagement with a portion adjacent the other end of the body member.

Abstract: A system and method are disclosed whereby a crane boom assembly of relatively long length and large load carrying capacity may be automatically stowed and carried on the superstructure of a crane assembly. With the boom assembly in the stowed position, the boom and superstructure combination may be carried on a single truck and trailer combination for highway transport. Power driven means are provided for unstowing and stowing the boom assembly with respect to the superstructure. To unstow the boom assembly, first power driven means are provided to translate the boom forwardly with respect to the superstructure.
