The invention relates to a crane boom head and a crane, the crane boom head comprises a boom head body (10) and a first pulley assembly (20), the boom head body (10) comprises a connecting part (11), the connecting part (11) is used for being connected with an extension jib, the first pulley assembly (20) is installed on the boom head body (10), and the first pulley assembly (20) and the connecting part (11) are spaced by a preset distance. Therefore, interference between the first pulley assembly (20) and the extension jib is avoided. The crane comprises the crane boom head. Integrated transportation of the pulley structure and the crane boom head can be achieved, the transportation cost is reduced, interference between the first pulley assembly and the extension jib can be avoided by enabling the first pulley assembly and the connecting part to be separated by the preset distance, when the extension jib needs to be installed on the crane, the pulley structure does not need to be disassembled and assembled, and the transportation efficiency is improved. The disassembly and assembly time of the crane can be saved, and the function of the pulley structure can be reserved for standby application, so that the operation efficiency of the crane is improved.

    本发明涉及一种起重机臂头和起重机,其中,起重机臂头包括臂头本体(10)和第一滑轮组件(20),臂头本体(10)包括连接部(11),连接部(11)用于与加长臂连接,第一滑轮组件(20)安装于臂头本体(10)上,第一滑轮组件(20)与连接部(11)之间相隔预设距离,以避免第一滑轮组件(20)与加长臂之间发生干涉。起重机包括上述起重机臂头。本发明可实现滑轮结构和起重机臂头的一体化运输,降低运输成本,通过使第一滑轮组件与连接部之间相隔预设距离,可避免第一滑轮组件与加长臂之间发生干涉,在起重机需要安装加长臂时,无需对滑轮结构进行拆装,可节省起重机的拆装时间,还使得滑轮结构的功能得以保留以便备用,从而提高起重机的作业效率。
