ABSTRACT:
A hoisting cage for hoisting concrete forms and building materials in the general shape of a polygonal box with a top and a bottom, capable of holding concrete forms and building materials and having vertical bars at the edges of the cage and a plurality of horizontal bars attached to the vertical bars, at least two inverted V-shaped trusses positioned such that the apex of each truss is below the top of the cage, and a rotatable catch or hoisting bar for receiving the grasp of a lifting apparatus is disclosed. The hoisting cage is capable of being hoisted by the lifting apparatus because the mechanical stresses due to lifting the weight of the hoisting cage and its contents are transmitted through the trusses and distributed substantially to the vertical bars of the cage. The pivoting catch is capable of lying flat on top of the hoisting cage thereby reducing the overall height of the hositing cage in order to facilitate its transportation under low bridges.
