The invention provides a double-purpose crane. The crane comprises a caterpillar band telescopic arm crane arm rest unit, a caterpillar band crane arm rest unit, a rotary table and a lower crane. The rotary table is connected with the lower crane through a rotary support, and hinge points which are matched with the caterpillar band telescopic arm crane arm rest unit and the caterpillar band crane arm rest unit are arranged on a rotary table frame; and function replacement of the double-purpose crane can be achieved through replacement of the caterpillar band telescopic arm crane arm rest unit and the caterpillar band crane arm rest unit. The double-purpose crane is simple in structure, reasonable and compact. The rotary table and the lower crane are used in common, a user only needs to replace an arm rest unit, and rapid replacement of two different cranes can be achieved.
