The invention provides a frame assembly and a crane. The frame assembly comprises a crane chassis (1), a supporting leg assembly (2) and a connecting device (3) for connecting the crane chassis (1) and the supporting leg assembly (2), the connecting device (3) comprises a power unit (31) and a pair of executing rods (32) extending outwards or retracting from the two ends of the power unit (31), the connecting device (3) can be switched between a first state and a second state, in the first state, the executing rods (32) extend out, and in the second state, the executing rods (32) extend out; the crane chassis (1) is connected with the supporting leg assembly (2) through a connecting device (3); and in the second state, the pair of executing rods (32) are retracted, and the crane chassis (1) and the supporting leg assembly (2) are disconnected. Through the arrangement of the frame assembly, the supporting leg unit and the bottom frame are easy and rapid to disassemble and assemble, the transition efficiency is improved, and the service life of the supporting leg assembly can be greatly prolonged through the frame assembly in the installation mode.
本申请提供了一种车架组件及起重机。车架组件包括起重机底架(1)、支腿组件(2)及连接起重机底架(1)和支腿组件(2)的连接装置(3),连接装置(3)包括动力单元(31)和从动力单元(31)的两端向外伸出或缩回的一对执行杆(32),连接装置(3)能够在第一状态和第二状态间切换:在第一状态,一对执行杆(32)伸出,起重机底架(1)和支腿组件(2)通过连接装置(3)连接在一起;在第二状态,一对执行杆(32)回缩,起重机底架(1)和支腿组件(2)解除连接。通过这样设置车架组件,支腿单元和底架拆装简单快速,提高了转场效率,这种安装方式的车架组件可以极大的延长支腿组件的使用寿命。
