The present application relates to the field of lifting equipment, in particular to a crane and a control method thereof. The crane includes: a body including a chassis and a turntable being rotatably arranged on the chassis; a super-lift device including a super-lift jib, a suspension pulling member and a balancing mechanism, the balancing mechanism including a super-lift counterweight and a pushing device, first ends of the super-lift jib and the pushing device being both connected to the turntable, the suspension pulling member being connected to a second end of the super-lift jib and the super-lift counterweight, a second end of the pushing device being connected to the super-lift counterweight to adjusting a distance between the super-lift counterweight and a slewing center of the turntable; and a hovering device configured to support the super-lift counterweight above a ground when the crane is under no load, a first end of the hovering device being connected to the turntable and a second end of the hovering device being not connected to the super-lift jib. Based on this, the function of slewing and traveling of the crane under no load while carrying the super-lift counterweight is achieved more conveniently.
