Abstract:
A system for lifting of massive construction object, comprising at least one of a plurality of columns, includes:at least two of a plurality of lifting supports, each of which comprising at least two of a plurality of vertically positioned H-girders rigidly installed by their lower parts on a base, wherein said H-girders are parallel to each other; and the distance between them is adequate for a passage of a sling-traverse coupled with a pivoting stand; at least two of a plurality of rests rigidly attached to the inner side of said the H-girders and strengthened by at least one strengthening support; at least one of a plurality of auxiliary strengthening girders rigidly attached to the outer side of said the H-girders; a lifting device, including a cross-girder housed in the upper part of said H-girders; a lifting sectional tape coupled by the lowest part with a flange of said sling-traverse and by upper part with said cross-girder of said lifting device; at least one of a plurality of temporary strengthening girders, coupling said H-girders above said flange of said sling-traverse, and wherein an appropriate quantity of said at least one of a plurality of temporary strengthening girders are removed from said H-girders above said flange of said sling-traverse after each lifting cycle providing a passage of a corbel of said massive construction object during the subsequent lifting cycle; at least one of a plurality of permanent strengthening girders, coupling said H-girders below said pivoting stand of said sling-traverse, and wherein said at least one of a plurality of permanent strengthening girders are installed on said H-girders bellow said pivoting stand after said each lifting cycle.
