Abstract:
A system for stabilizing and controlling in six degrees of freedom the movement of a hoisted load, said system comprising:(a) a suspension point, (b) an assembly, (c) a lateral tension lines member, and (d) a control system, said assembly comprising (i) a first platform for positioning said assembly, (ii) a second platform disposed below said first platform, (iii) first, second, third, fourth, fifth, and sixth control lines having a first end and a second end, said control lines disposed between said first platform and said second platform, and (iv) an assembly/load hoist, said assembly/load hoist comprising an assembly/load hoist line and an assembly/load hoist connector, said assembly/load hoist line in communication with an assembly/load hoist line length adjuster, said first platform comprising a first platform upper surface, a first platform lower surface, a first platform outer edge, and a plurality of lateral tension line connectors for engaging a plurality of lateral tension lines for providing lateral tension to said first platform said plurality of lateral tension lines in communication with a corresponding one of a plurality of lateral tension line length adjusters, said first platform upper surface comprising a plurality of assembly/load hoist line connectors for removably engaging said assembly/load hoist, said first platform lower surface comprising first, second, and third control line end connector pairs for removably engaging said first end of each of said first, second, third, fourth, fifth, and sixth control lines, said control line end connector pairs being arranged in a substantially triangular configuration on the first platform lower surface, said first control line end connector pair engaging said first and said sixth control lines, said second control line end connector pair engaging said second and said third control lines, and said third control line end connector pair engaging said fourth and said fifth control lines, said second platform comprising a second platform upper surface, a second platform lower surface, and a second platform outer edge, said second platform upper surface comprising first, second, third, fourth, fifth, and sixth control line length adjusters for adjusting the length of each of said corresponding first, second, third, fourth, fifth, and sixth control lines, said control line length adjusters being arranged in first, second, and third control line length adjuster pairs in a substantially triangular configuration on the second platform upper surface and in communication with said second end of a corresponding one of said first, second, third, fourth, fifth, and sixth control lines, said first control line length adjuster pair comprising said first and said sixth control line length adjusters, said second control line length adjuster pair comprising said second and said third control line length adjusters, and said third control line length adjuster pair comprising said fourth and said fifth control line length adjusters, wherein said substantially triangular configuration of control line length adjuster pairs is oriented relative to said substantially triangular configuration of control line end connector pairs such that each vertex of the control line length adjuster pairs configuration is at a position diametrically opposed to a side of the control line length adjuster pairs configuration, said second platform lower surface comprising a load connector for removably engaging said load.
