It can effectively solve the problems encountered in the impeller tooling process, and the operation on the tooling base can ensure that the impeller does not overturn during the hoisting process. The tooling adopts split-type mechanism, assembled after entering the field. The tooling supports can be designed according to the weights of impeller and hub. It is especially suitable for construction sites with complex landforms and limited sites, such as forest areas, which can reduce the number of cranes required for assembly, and only one crane can complete the whole erection process, minimizing the impact on the native landforms.

In order to meet the structural strength, the support legs of the fixture bracket are all made of box girder structure with stable and reliable performance. The tooling is directional installation of the impeller, and the structure is installed in the same direction as the brackets. The structural support legs use a quick disassembly structure, which can realize fast and orderly installation, shorten the construction time, and greatly improve the efficiency and safety of the tooling.
