The invention relates to the technical field of mechanical hoisting, in particular to a rotary platform and a crawler crane. The rotary platform can be used for construction under a first working condition and comprises a main rotary table and at least three lifting hoisting mechanisms; the lifting hoisting mechanisms are arranged on the main rotary table respectively, two of the lifting hoistingmechanisms are used for being matched together to achieve a first working condition, and the other lifting hoisting mechanism is used for achieving a second working condition. A plurality of listing hoisting mechanisms can be arranged, and construction requirements under different working conditions are met.

    本发明涉及机械起重技术领域,具体而言,涉及一种回转平台和履带起重机。一种回转平台,其能够用于第一工况施工,包括主转台和至少三个提升卷扬机构;提升卷扬机构均设置在主转台上,其中两个所述提升卷扬机构用于共同配合实现第一工况,另一所述提升卷扬机构用于实现第二工况。其能够布置多个提升卷扬机构,满足不同工况下的施工要求。
