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.
