The invention discloses a combined arm support and a crane. The combined arm support comprises a plurality of single arm supports and a plurality of connecting pieces, each single arm support comprises a main arm section, a first connecting section and an arm head used for installing a lifting piece of a lifting device, in a first arm head connecting mode, the first connecting section is detachably connected between the main arm section and the arm head, in a second arm head connecting mode, the main arm section is overturned by 90 degrees around the length direction relative to the main arm section in the first arm head connecting mode, and the arm head is directly connected with the overturned main arm section. In a first tonnage hoisting mode, the multiple single arm supports are adjacently arranged, the multiple connecting pieces are detachably connected with the multiple single arm supports, the arm head connecting mode of the single arm supports is one of the first arm head connecting mode and the second arm head connecting mode, and when the first tonnage hoisting mode is switched to the second tonnage hoisting mode, parts of the single arm supports are detached. The arm head connecting mode of the rest of the single arm supports is switched to the other one of the first arm head connecting mode and the second arm head connecting mode.
本发明公开一种组合式臂架和起重机,组合式臂架包括多个单臂架、多个连接件,单臂架包括主臂节、第一连接节和用于安装起升装置的起升件的臂头,在第一臂头连接模式,第一连接节可拆卸地连接在主臂节和臂头之间,在第二臂头连接模式,主臂节相对第一臂头连接模式下的主臂节绕长度方向翻转九十度,臂头与翻转后的主臂节直接连接;在第一吨位吊重模式,多个单臂架相邻布置,多个连接件可拆卸地连接多个单臂架,单臂架的臂头连接模式处于第一臂头连接模式和第二臂头连接模式中的一种模式,在第一吨位吊重模式切换至第二吨位吊重模式时,部分单臂架被拆除,且剩余的单臂架的臂头连接模式切换至第一臂头连接模式和第二臂头连接模式中的另一种模式。
