The invention discloses a cantilever crane and an overhead working truck, and relates to the technical field of overhead working trucks. The boom comprises a main boom and a plurality of telescopic booms, the main boom and the telescopic booms are sequentially connected in a sleeved mode, each of the main boom and the telescopic booms is provided with a cross section in a set shape, the set shape comprises a first side face, a second side face and a third side face, the first side face and the second side face are oppositely arranged, and the third side face is used for connecting the first side face and the second side face. The middle of the first side face and the middle of the second side face are concave, and the middle of the third side face protrudes out of the two ends of the third side face. The cantilever crane has high rigidity while achieving light weight, it can be guaranteed that the telescopic arm stretches out in the middle, the stability of the cantilever crane is improved, and the safety of the overhead working truck applying the cantilever crane is guaranteed.

    本发明公开了一种臂架及高空作业车,涉及高空作业车技术领域。该臂架包括主臂和多个伸缩臂,主臂和多个伸缩臂依次套接,主臂和多个伸缩臂均具有设定形状的横截面,设定形状包括第一侧面、第二侧面和第三侧面,第一侧面和第二侧面相对设置,第三侧面用于连接第一侧面和第二侧面,第一侧面的中部和第二侧面的中部均设置为内凹状,第三侧面的中部凸出第三侧面的两端设置。该臂架在实现轻量化的同时具有较强的刚度,且能保证伸缩臂居中伸出,提高臂架的稳定性,保证应用该臂架的高空作业车的安全性。
