The invention relates to a six-pedal grab bucket special for four-cable scrap steel. The six-pedal grab bucket special for four-cable scrap steel comprises an upper bearing beam, supporting rods, a bucket body, a lower bearing beam, a steel wire rope, a moving beam and a hanging crosspiece, wherein the top ends of the supporting rods are connected with the upper bearing beam, the bottom ends of the supporting rods are hinged to the bent portion of the middle of the bucket body, the upper end of the bucket body is hinged to the lower bearing beam, the steel wire rope sequentially penetrates through the moving beam and the upper bearing beam to be connected with the hanging crosspiece, and the upper bearing beam comprises an upper bearing body, oil cylinders and spherical joints. Guide grooves are formed in the upper bearing body, the six guide grooves are respectively and evenly formed along the central axis of the upper bearing body in the peripheral direction, the bottom ends of the oil cylinders are connected with the top ends of the supporting rods through the spherical joints, and the top ends of the oil cylinders are connected with the upper bearing body. The motion of the single supporting rod of the six-pedal grab bucket special for four-cable scrap steel is controlled through pressure difference, and the pressure borne by one supporting rod or multiple supporting rods is reduced, so that the six-pedal grab bucket achieves an asynchronous acting function when grabbing the scrap steel, the damage of the six-pedal grab bucket is reduced, and the service life of the six-pedal grab bucket is prolonged.
