Abstract : The device features the elimination of bending moments in all members to allow a design of minimal weight, and depends on the use of an existing structure to provide stabilizing reactions when erected. A rigid mast is pivoted at its lower end on the existing structure, and supports a block and tackle at its upper end. A rigid triangular spreader and cable assemblies support the mast. (Author)
