FIELD: transport.
SUBSTANCE: invention relates to construction, particularly, to overhead crane girders. Carne girder is composed of top and bottom belts, vertical wall, and vertical crosswise ribs. Girder vertical wall top part features V-like shape extending from top belt to neutral axis. Said wall is composed of one vertical sheet and two symmetric inclined flat sheets secured, by their one side over girder length, to vertical sheet and, by other side, to top belt. Vertical crosswise ribs are arranged at definite spacing and secured to girder bottom belt, vertical sheet and inclined sheets.
EFFECT: increased cyclic load at girders at severe operating conditions.
