The invention discloses a transmission vibration reducing structure of a crane lifter. The transmission vibration reducing structure comprises a lifter body, a dual-folding type lifting frame fixed on the lifter body, and a supporting table fixed at the upper end of the lifting frame; the lifting body is provided with a rolling wheel. The transmission vibration reducing structure is characterized in that the lifter body comprises a hydraulic cylinder used for providing power source, a first bottom plate and a second bottom plate; multiple vibration reducing devices are arranged between the first bottom plate and the second bottom plate, and each of the vibration reducing devices comprises a first cushion ring, a vibration reducing spring and a second cushion spring which are arranged in order; the first bottom plate and the second bottom plate are fixed together by crossing through the vibration reducing devices by a bolt. The transmission vibration reducing structure of the crane lifter is simple in structure, strong in practicability, convenient to lift, and good in vibration reducing effect, and the like.
