The invention relates to lift for the multipoint mounting , which is used mainly in a method for lifting of packages of slabs on medium height in their construction and mounting by lifting the other types of building structures. The lift for multipoint mounting, includes two cargo bridges - upper / 7 / and lower / 4 / is mounted at the lower loading bridge / 4 /. Between cargo bridges / 4 and 7 /, symmetrical of their centers, are fixed two double acting hydraulic jacks / 5 /, in which through the two bridges /4 and 7/, and symmetrically of the two jacks / 5 / is drilled power screw /10/ witha security nut / 1 / for each bridge / 4 and 7 /. To each nut / 1 / via a gear drive / 3 / is connected an electric or a hydraulic motor / 2 /, wherein to the lower end of the screw /10/ is fixed an additional cargo bridge / 12 /, to which by means of two grip bars / 13 / is connected a raised building structure /14/. Through the building structure /14/ , the lower bridge / 7 / and the additionalbridge / 12 / and symmetrical to the power screw /10/ have been built carrying columns / 11 / with transverse openings /9/, for placing carrying pins /8/, which are fixing the lower bridge /7/ or theadditional bridge /12/. The lift is provided with a pair of supporting pillars /16/ with transverse openings /18/, the one end of which has a centering pin /15/ for their axial attachment to the carrying columns /11/. The lift for multipoint mounting has reliable and safe design, simple assembly and convenient operational level.
