The invention provides an arm stand assembly and a crane and relates to the technical field of engineering machinery. One end of a main arm is connected to a lower vehicle body of the crane while theother end of the main arm is hinged to one end of an amplitude changing auxiliary arm, and an amplitude changing part is connected to the main arm and the amplitude changing auxiliary arm, separately.The other end of the amplitude changing auxiliary arm is connected to one end of a fixed auxiliary arm, and a fixed part is connected to the amplitude changing auxiliary arm or the fixed auxiliary arm, separately. Or, the other end of the main arm is connected to one end of the fixed auxiliary arm, and the fixed part is connected to the main arm and the fixed auxiliary arm, separately, for fixingthe fixed auxiliary arm to the main arm. The other end of the fixed auxiliary arm is hinged to one end of the amplitude changing auxiliary arm, and the amplitude changing part is connected to the fixed auxiliary arm and the amplitude changing auxiliary arm, separately, for adjusting the amplitude of the amplitude changing auxiliary arm to the fixed auxiliary arm. The operating radius of the arm stand assembly can be increased while the lifting height of the arm stand assembly is improved effectively, so that the arm stand assembly meets a more complex construction condition and improves the applicability of the crane.
本发明提供一种臂架组件和起重机，涉及工程机械技术领域，主臂的一端用于连接起重机的下车体。主臂的另一端与变幅副臂的一端铰接，变幅件分别与主臂和变幅副臂连接。变幅副臂的另一端与固定副臂的一端连接，固定件分别与变幅副臂和固定副臂连接。或，主臂的另一端与固定副臂的一端连接，固定件分别与主臂和固定副臂连接，用于将固定副臂相对主臂固定；固定副臂的另一端与变幅副臂的一端铰接，变幅件分别与固定副臂和变幅副臂连接，用于调整变幅副臂相对固定副臂的幅度。可以在有效提高臂架组件的提升高度的同时，扩大臂架组件的作业半径，从而满足更加复杂的施工工况，提高起重机的适用性。
