ferrous and non-ferrous metallurgy; heavy-duty cranes. SUBSTANCE: proposed crane rail is hollow and is provided with head with horizontally and vertically orientated roll surfaces for main wheels of crane and its guide rollers, and it has axis of symmetry directed at angle of 45° to roll surface. Two horizontally and vertically orientated necks adjoin the head from side and bottom. Each neck has orthogonally orientated foot connected with subcrane structure by hollow rivets with fitted in cores. Main wheels of crane interact with horizontal roll surface of rail head, and crane guide rollers, with vertical roll surface of head. EFFECT: enlarged operating capabilities of rail, possibility of its operation as common unit in section of rail-and-beam structure. 1 dwg
