The invention discloses a movable anti-theft system suitable for a crane and the crane, and belongs to the technical field of engineering mechanical equipment. The crane comprises a main machine, a counterweight unit, a variable-amplitude transmission mechanism, a cargo boom and a lifting transmission mechanism, wherein an arm section connecting piece is arranged at the upper part of the counterweight unit; the anti-theft system comprises a base, a tower and a monitoring mechanism. In a lifting state, the counterweight unit is detachably and fixedly connected to one side of the main machine, and the lifting arm comprises a plurality of detachably fixed arm sections; in an anti-theft state, the counterweight unit is separated from the host and serves as the base; at least the boom section located at the top end of the cargo boom is separated from the cargo boom, and the top end of the boom section faces upwards and is fixedly installed on the balance weight unit through the boom section connecting piece to serve as the tower; the monitoring mechanism at least comprises a camera installed on the top of the tower. The anti-theft device can achieve the anti-theft function when the crane is hoisted and idle, and key components can be prevented from being stolen without disassembly and assembly.
