The utility model discloses a carriage upper edge beam, which comprises a slot-shaped beam composed of a base board and two laterals boards, wherein the edge of one lateral board of the slot-shaped beam bends inwards vertically to form an inward reinforced bar board, and the edge of the other lateral board of the slot-shaped beam bends outwards vertically to form an outward reinforced bar board. By adopting the technical scheme, the edge of one lateral board of the slot-shaped beam bends inwards vertically and the edge of the other lateral board of the slot-shaped beam bends outwards vertically, namely the two lateral boards bend vertically in the same direction, so that rigidity and strength of the whole slot-shaped beam can be enhanced. The carriage upper edge beam is reasonable in design and simple in structure, can meet requirements for rigidity and strength improvement simply by bending on the basis of the existing slot-shaped beam, increases bearing capacity of a semitrailer base board, and accordingly
