The invention relates to the technical field of mechanical equipment, in particular to a lifting counterweight and a crane. The lifting counterweight is used in the crane. The lifting counterweight comprises a connecting rope and a movable counterweight; one end of the connecting rope is connected with a drum of the crane, the other end of the connecting rope is connected with the movable counterweight, and the drum is rotated to drive the connecting rope to move, so that the connecting rope pulls the movable counterweight to be raised or lowered. The lifting counterweight drives the movable counterweight to be raised by the connecting rope. The device has a simple structure and low cost, and solves the problem of non-synchronization in a way of using an oil cylinder to drive the movable counterweight.
