The invention discloses a hoisting sling and a hoisting device of a cable crane, and relates to the technical field of bridge construction equipment. The hoisting sling comprises a carrying pole beam used for being connected with a hoisting mechanism; the connecting mechanism is used for being connected with the steel truss girder; and the middle part of the rope loop is wound on the carrying pole beam, and the rope loop bypasses two ends of the carrying pole beam and is connected with the connecting mechanism. When the lifting appliance is used, the lifting mechanism is lowered to the top of the steel truss girder, the lifting mechanism and the carrying pole beam are connected, the middle of the rope loop is wound on the carrying pole beam and wound around the two ends of the carrying pole beam to be connected with the connecting mechanism, the connecting mechanism is connected with the steel truss girder, and at least two sets of lifting appliances are used in the lifting process. According to the hoisting sling, the rope loop is adopted for connecting the carrying pole beam and the connecting mechanism, the coordination of the flexible connecting structure is high, the hoisting sling can adapt to small-angle rotation generated when a plurality of groups of hoisting slings are adopted for hoisting a steel truss beam at multiple points, the adverse effect on the hoisting sling is reduced, and the safety in the construction process is improved.
本申请公开了一种缆索吊的吊装吊具及吊装装置,涉及桥梁施工装备技术领域,该吊装吊具包括扁担梁,其用于与吊装机构连接;连接机构,其用于与钢桁梁连接;绳圈,其中部绕设在所述扁担梁上,所述绳圈绕过所述扁担梁的两端与所述连接机构连接。使用该吊装吊具时,下放吊装机构至钢桁梁顶部,连接吊装机构与扁担梁,绳圈中部绕设在扁担梁上,绕过扁担梁的两端与连接机构连接,连接机构与钢桁梁连接,吊装过程中至少使用两组吊装吊具。该吊装吊具采用绳圈连接扁担梁与连接机构,柔性连接结构的协调性高,可适应采用多组吊装吊具多点起吊钢桁梁时产生的小角度转动,减小了对吊装吊具的不良效应,提高了施工过程的安全性。
