The invention discloses a low-wind-resistance quay crane main beam. The low-wind-resistance quay crane main beam comprises a box-shaped structure and a plurality of through holes formed in the box-shaped structure. The box-shaped structure comprises an upper wing plate, a lower wing plate, a straight web plate and an inclined web plate, the straight web plate and the inclined web plate are connected between the upper wing plate and the lower wing plate, and the straight web plate is a windward side; a plurality of partition plates which are distributed at equal intervals are arranged in the box-shaped structure; the through hole penetrates through the straight web plate and the inclined web plate; and each through hole is formed in the position between the two partition plates. According to the invention, the windward area can be effectively reduced.
