The invention relates to the technical field of tower cranes, and provides an arm support structure and a tower crane, the arm support structure comprises a first arm support assembly, the first arm support assembly comprises a plurality of first arm sections which are sequentially connected in the length direction of the first arm support assembly; the first arm section comprises a plurality of first arm frame units arranged in an array mode, the array arrangement comprises two arrangement directions of the width direction and the height direction of the first arm frame assembly, every two adjacent first arm frame units in the width direction are fixedly connected, and every two adjacent first arm frame units in the height direction are connected with each other. Compared with a cantilever crane structure made of a high-strength material in the prior art, the multiple first cantilever crane units which are arranged in an array and fixedly connected are adopted, so that the number of the cantilever crane units in the width direction and the height direction is increased, and the material lifting weight can be greatly improved; in addition, due to the fact that the structures of the first arm frame units arranged in the array mode are the same, the production cost is effectively saved.
本发明涉及塔机技术领域,并提供了一种臂架结构及塔机,所述臂架结构包括第一臂架组件,所述第一臂架组件包括沿所述第一臂架组件的长度方向依次连接的多个第一臂节;第一臂节包括阵列设置的多个第一臂架单元,阵列设置包括第一臂架组件的宽度方向和高度方向两个排列方向,沿宽度方向上相邻的两个所述第一臂架单元之间固定连接,沿高度方向上相邻的两个所述第一臂架单元之间相互连接。本发明采用阵列排列固定连接的多个第一臂架单元相对现有技术中使用高强度材料制成的臂架结构而言,因增加了宽度和高度方向上臂架单元的数量,从而可以大幅度提高对物料的起重重量,并且由于阵列排列设置的多个第一臂架单元的结构相同,还有效节约生产成本。
