The invention discloses a counterweight device. The counterweight device comprises a counterweight unit, a pulley block and an impact stress unit, and is characterized in that the counterweight unit is formed by superposing a plurality of steel plates and fastening the steel plates through bolts and nuts; the pulley block comprises two fixed pulleys which are spaced from each other at a certain interval and are arranged horizontally; a steel wire rope penetrates through the two fixed pulleys; the impact stress unit is a mechanism needing to reduce a stress action; one end of the steel wire rope is connected with the counterweight unit through a connecting device, and the other end of the steel wire rope is connected with the impact stress unit through another connecting device; the counterweight unit is arranged right below a pulley fixing base of one of the fixed pulleys; the impact stress unit is arranged right below a pulley fixing base of the other fixed pulley. The counterweight device and application thereof have the advantages that the service lives of a tray lifting device chain and a transmission device driving shaft are prolonged, so that the occurrence efficiency of an accident and the repair labor intensity of a worker are reduced.
