The invention relates to the field of hoisting equipment, and provides a crane boom head, a crane boom and hoisting machinery, and the crane boom head comprises a boom head and m transition knuckle arms. The arm head comprises an arm head body and a connecting arm, and the connecting arm is connected with the arm head body. And when m is greater than or equal to 2, the m transition section arms are sequentially nested, the connecting arm is nested in the mth transition section arm, and the first transition section arm is nested in the last telescopic section arm of the cargo boom. And clamping structures are arranged between the connecting arm and the mth transition section arm, between two adjacent transition section arms and between the first transition section arm and the last telescopic section arm. When the length of the cargo boom needs to be prolonged, the first transition section arm is replaced by a telescopic section arm with the same cross section as that of the first transition section arm, only the telescopic section arm needs to be additionally arranged on the basis of an original cargo boom in the mode of prolonging the length of the cargo boom, the cargo boom does not need to be wholly replaced, the cost is greatly saved, and the working efficiency is improved. And the waste of resources is also reduced.

    本发明涉及起重设备领域,提供一种起重机臂头、起重臂和起重机械,包括臂头和m节过渡节臂。臂头包括臂头主体和连接臂,连接臂与臂头主体连接。当m≥2时,m节过渡节臂依次嵌套设置,连接臂嵌套在第m节过渡节臂内,第一节过渡节臂嵌套在起重臂的最后一节伸缩节臂内。连接臂与第m节过渡节臂之间、相邻两节过渡节臂之间以及第一节过渡节臂与最后一节伸缩节臂之间均设置有卡接结构。当需要延长起重臂的臂长时,使用一根与第一节过渡节臂的横截面相同的伸缩节臂替换掉第一节过渡节臂即可,此种延长臂长的方式只需在原有的起重臂的基础上增加伸缩节臂即可,无需整体更换起重臂,大大节省了成本,也减少了资源的浪费。
