The invention discloses a folding type cargo boom which comprises a folding arm connected to a telescopic cargo boom, an angle changing mechanism is arranged between the folding arm and the telescopic cargo boom, the section of the folding arm is triangular, the folding arm comprises a main arm and an auxiliary arm, and the connecting end of the auxiliary arm is detachably connected with an upper chord and/or a lower chord of the connecting end of the main arm correspondingly. The auxiliary arm can rotate by 180 degrees around a lower chord member at the connecting end of the main arm to be folded to the position below the main arm. According to the folding type cargo boom, the folding arm with the triangular section is used for the first time, so that the amplitude of an automobile crane is increased, folding and angle changing of the folding arm can be achieved, the auxiliary arm is further lengthened, the operation space of the automobile crane in the height and amplitude is increased, the folding structural form of the auxiliary arm is novel, and the hoisting requirement is met; all the parts are detachably assembled and connected, the structure is simple, maintenance is rapid, safety and reliability are achieved, and transition is convenient.

    本发明公开了一种折叠式起重臂,包括连接于起重伸缩臂上的折叠臂,所述折叠臂与起重伸缩臂之间设有变角机构,所述折叠臂截面为三角形,包括主臂和副臂,所述副臂连接端与主臂连接端的上弦杆和/或下弦杆分别对应可拆卸连接,所述副臂能够绕主臂连接端的下弦杆旋转180度折叠至主臂下方。本发明所述折叠式起重臂首次使用三角形截面的折叠臂使汽车起重机增加变幅,可实现折叠臂的折叠与变角,副臂进一步加长,提高汽车起重机在高度和幅度上的作业空间,副臂折叠的结构形式新颖、满足吊装要求,且各部件均采用可拆卸式装配连接,结构简单,维修快速,安全可靠,转场方便。
