Summary:FIELD: mechanical engineering; materials handling facilities. SUBSTANCE: proposed crane has main beam, two vertical portals, each arranged on support platform with supporting-and-running trucks, and load-lifting equipment. Main beam is boxsection, sectional. Support platform is made in form of rigid horizontal frame on crossmembers of which tracks for nondriven support trolley are rigidly secured. Load-lifting equipment is system of tackle blocks with electric winches. Standing blocks of all tackle blocks and said electric winches are arranged inside main beam. Two said tackle blocks of system are arranged, each, on main beam in plane of corresponding vertical portable. Crane is provided with two tilted portals. Lower ends of each of tilted portals and vertical portals are hinge-connected with frame of support platform, and their upper ends are rigidly connected to main beam. EFFECT: increased capacity at mounting of bridge frameworks. 5 dwg
