The invention discloses an arm support system of a multi-stage statically indeterminate structure and a crane. The arm support system comprises at least two superlift structures, the superlift structures are arranged in the direction of the arm frame; one end of the upper side of the first superlift structure is connected with the tail of the basic arm of the main arm through a pull plate or a steel wire rope, and the other side is connected with the upper side of the next superlift structure through a steel wire rope or a pull plate; the lower side of the next superlift structure is connected with the main arm or the auxiliary arm, and the upper side of the next superlift structure is connected with the upper side of the next superlift structure; the lower side of the last superlift structure is connected with the main arm or the auxiliary arm, and the upper side of the last superlift structure is connected with any point of the main arm or the auxiliary arm. According to the cantilever crane system of the multi-stage statically indeterminate structure, the bearing capacity of the cantilever crane system can be improved by increasing the acting force arm length of the super-lift pulling plate or the steel wire rope.

    本发明公开了一种多级超静定结构的臂架系统及起重机,该臂架系统包括至少2个超起结构;各超起结构沿臂架方向布置;第一个超起结构的上侧一端通过拉板或钢丝绳与主臂基本臂臂尾连接,另一侧通过钢丝绳或拉板与下一个超起结构的上侧连接;下一个超起结构的下侧与主臂或副臂连接,上侧与下一个超起结构的上侧连接;以此类推,最后一个超起结构的下侧与主臂或副臂连接,上侧与主臂或副臂任意一点连接。本发明的多级超静定结构的臂架系统可以通过提升超起拉板或钢丝绳起作用的力臂长度,提升臂架系统承载能力。
