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.

    本发明涉及一种上拱式平衡梁,包括挂梁、滑轮组和龙门钩,所述滑轮组设置在挂梁上部,所述龙门钩设置在挂梁两端的下部,所述挂梁包括平直部和上供部,平直部设置在上供部两端,所述挂梁中部的上供部的中部开设有通孔,所述通孔内通过连接机构设置有吊钩组;可以达到吊钩上极限小、能降低起重机重量、节省成本的效果。
