Abstract

Improvements introduced in an aerial lifting apparatus for transporting equipment and/or personnel, the apparatus comprising: support means, a boom having an extensible load end and a pivot end; means for mounting said boom on said support means in such a manner that said pivot end is movable in the horizontal direction; a support arm extending between said supporting means and said boom and which is pivotably connected to them; means rigidly coupling said support arm with the extendable end of said boom; and means for raising and lowering said boom so that, when said boom is raised, the pivoting end of said boom moves substantially in horizontal direction, said support arm pivots about said support means and said boom, and said means coupling said support arm to the extendable end of said boom cause said extensible portion to extend to raise the load end of the boom in a substantially vertical direction.
