According to a heavy object baling method, wooden frame baling serves as a mainstream; if a professional practitioner is entrusted to carry out baling operation, several days need to be spent until completion, and due to the fact that fumigation treatment needs to be carried out, the number of days is also accumulated, and the shipment day is delayed. Besides, due to the fact that the material ofthe wooden frame bale has weight, transportation cost is increased, bale breaking operation is changed into manual labor, and therefore the risk of injury is high. And in addition, the unpacked wood becomes industrial waste, so that the treatment cost is generated. Components are placed at the four corners of the bottom side or the four corners of the bottom side and the four corners of the top side of an object to be baled, or a pedestal is arranged at the bottom side of the object to be baled, so that the components are placed at the pedestal and the four corners of the top side, and balingwork is completed through binding belts. Due to the fact that the baling operation can be completed in a short time on the site of one side of the baler, fumigation treatment is not needed, and the baler is made of resin, the baler is light in weight, unbaling operation is easy, and waste can be reduced due to the fact that the baler can be reused.
