The invention discloses a crane balancing weight displacement device which comprises a rotary table, a telescopic suspension arm, a suspension arm rotation driving assembly and a balancing weight assembly, a rotary table pulley is arranged at the tail end of the rotary table, one end of the telescopic suspension arm is hinged to the rotary table, and a pulley block is installed on the arm head of a tail section arm of the telescopic suspension arm. The lifting arm rotation driving assembly is installed on the rotary table and drives the telescopic lifting arm to rotate relative to the rotary table, the balance weight assembly comprises balance weights capable of sliding along slideways on the two sides of the rear wall and the bottom of the rotary table, and the balance weights are connected with the tail end of a steel wire rope; according to the crane, the displacement mode is simple, the cost is low, the displacement mode adopted in the scheme only needs to locally change a structural part, a power device does not need to be added, displacement can be achieved only through the telescopic action of the crane, and the crane is convenient to use and high in practicability. The cost is not increased during product design, the use is relatively convenient, and the cost is low.
