The invention relates to a lifting sling and method for large equipment and belongs to the technical field of equipment lifting. The lifting sling and method are used for solving the problems that when the large equipment is lifted, time consumed for adjusting the lengths of branch lifting sling bodies is long, difficulty is high, and deformation of the equipment is easily caused. The lifting sling comprises a plurality of lifting assemblies which sequentially stretch across and are fixed to an equipment base. Each lifting assembly comprises main lifting sling bodies, a transverse support and branch lifting sling bodies. The transverse supports are suspended on the equipment through the main lifting sling bodies. The branch lifting sling bodies are fixed on the two sides of the equipment base respectively. The lifting method includes the following steps that firstly, the positions of the branch lifting sling bodies are determined, and the lengths and angles of the branch lifting sling bodies and the main lifting sling bodies as well as component forces of the branch lifting sling bodies in the vertical direction are worked out by the combination of a graphing method; secondly, the branch lifting sling bodies are installed and the positions of P are determined; thirdly, the transverse supports are arranged on the equipment; fourthly, the main lifting sling bodies are arranged on the transverse supports; and finally, a main lifting point of the main lifting sling bodies is fixedly connected with a lifting hook of a crane, and the crane is started to lift the equipment to a predetermined position.
