Hoisting cage with interior truss design

A hoisting cage for hoisting concrete forms and building materials, comprising:

• (a) a cage in the general shape of a rectangular box, with a top and a bottom, said cage being capable of holding concrete forms and building materials, said cage having a frame with vertical bars at the edges of said cage and a plurality of horizontal bars attached to said vertical bars;
• (b) at least two inverted V-shaped trusses, each truss having two ends and an apex in the middle of the truss, said trusses being positioned such that the apexes of said inverted V-shaped trusses are attached to the first and second horizontal bars at a point which is below the top of the cage, the first end of each of said inverted V-shaped trusses being attached to a vertical bar of said cage and the second end of each of said inverted V-shaped trusses being attached to another vertical bar of said cage;
• and
• (c) a hoisting bar for receiving the grasp of a lifting apparatus, said hoisting bar having two ends, the first end being rotatably attached to the first horizontal bar near the point where the apex of the first inverted V-shaped truss is attached to the first horizontal bar, the second end being rotatably attached to the second horizontal bar near the point where the apex of the second inverted V-shaped truss is attached to the second horizontal bar, such that the hoisting bar is capable of folding down to reduce the overall height of the hoisting cage in order to facilitate its transportation,
• whereby said hoisting cage is capable of being hoisted by a lifting apparatus secured to the hoisting bar and the mechanical stresses due to lifting the weight of the hoisting cage and its contents are transmitted through the hoisting bar to said inverted V-shaped trusses and then distributed substantially to the vertical bars of the hoisting cage.
