Connection of migrating and trailer beams Bridge cranes

摘要

The invention relates to hoisting and transport mechanical engineering, namely to designs of bridge cranes. The technical result of the claimed device is to increase operational reliability by increasing the relative position accuracy of the bridge elements: terminal and span beams, crane wheels from the factory to the installation site. compound of the transit node and the end beams of the bridge crane comprises a formed on the mating sides of the beam flanges with holes for bolted connection and the key cylinder with an outer annular bead. In the middle portions of the flanges of both beams are made coaxial holes for the key to facing each other recesses below the shoulder. Holes for screw connections are made from the sides of the flange and are arranged in vertical planes. The bottom flanges formed spaced horizontal openings for placement of pins with a clearance and set plate with threaded holes for the stud. 2 AM f ly-7-yl.
