The hoist is an auxiliary equipment for the height change of green billets. It is mainly used for the height change of green billets before and after entering and leaving the drying kiln. The hoist is selected according to the site requirements. The specifications and number of layers of the hoist are determined according to the product size, output, and number of layers of the drying kiln. The model and power of the main lifting motor are selected according to the number and size of the layers of the hoist. The stability of the lifting platform depends on the chain positioning. The positioning effect of the four main chains at the four corners is more ideal. The left and right directions are synchronized by gear sets, and the counterweight box eliminates the operating gravity to ensure stable operation. The electronic control is controlled in sections by the PLC program to link the upper and lower processes.
