The invention relates to the field of tower cranes, and particularly relates to a crane boom of a tower crane with a reinforcing device. The crane boom comprises crane sections, wherein a reinforcing mechanism for reinforcing the crane sections is arranged between the adjacent crane sections; the reinforcing mechanism comprises a first reinforcing sleeve fixedly arranged on a first straight rod in a sleeving manner, a second reinforcing sleeve fixedly arranged on a second straight rod in a sleeving manner, and a third reinforcing sleeve fixedly arranged on a third straight rod in a sleeving manner; the second reinforcing sleeve and the third reinforcing sleeve are symmetrically arranged relative to the vertical plane where the first straight rod is located; a connecting assembly is connected between the second reinforcing sleeve and the third reinforcing sleeve; and a supporting assembly is arranged between the first reinforcing sleeve and the connecting assembly. The crane boom has the effects of improving the stability among the first straight rod, the second straight rod and the third straight rod, reducing the possibility of fracture of steel structures of the first straight rod, the second straight rod and the third straight rod due to fatigue, and improving the stability of the structures among the steel structures.
