And jib crane

The invention discloses a jib and a crane. The jib comprises a jib main body and jib additional bodies; the jib main body is of a space truss structure, wherein at least one side face of the jib main body is detachably connected with one jib additional body; or, at least one side face of the jib main body is detachably connected with more than two stacked jib additional bodies. The jib additional bodies can be detachably connected with the jib main body; on a basis without changing the structure of the jib main body, the jib additional bodies can be increased according to the actual demand, to meet the requirements of hoisting equipment on the jib bearing capacity. Moreover, during transportation, the jib additional bodies can be detached with the jib main body and is transported alone according to the requirements of transportation size and transportation weight. Therefore, the jib of the embodiment not only can ensure the jib sufficient bearing capacity, but also can meet the requirements of transportation.
