The invention relates to an upwards-arched equalizing beam. The upwards-arched equalizing beam comprises a suspended beam, pulley sets and portal hooks, wherein the pulley sets are arranged at the upper portion of the suspended beam, the portal hooks are arranged at the lower portion of the two ends of the suspended beam, the suspended beam comprises a flat part and an upwards-arched part, the flat part is arranged at the two ends of the upwards-arched part, a through hole is formed in the portion, in the middle of the upwards-arched part, of the middle of the suspended beam, and a lifting hook set is arranged in the through hole through a connecting mechanism. The upwards-arched equalizing beam has the advantages that the upper limit of lifting hooks is small, the weight of a crane can belowered, and the cost is saved.
