As an 18 ton heavy-duty professional snow removal vehicle, its core function is large-scale snow melting and spreading operations in winter. It focuses on efficient spreading and precise quantity control, and is suitable for handling medium to heavy snow situations on urban main roads, highways, large industrial parks, etc. The dedicated device is a spreading machine, which is one of the core equipment for ensuring smooth road traffic in winter and has the qualification for compliant operation. Equipped with a large capacity V-shaped silo of 8 cubic meters, made of high-strength carbon steel material, the structure is stable and has excellent rigidity. The top can effectively protect the snow melting agent from moisture and compaction. A filter screen is placed on the silo to intercept large particles of debris, avoid equipment jamming, and ensure the safe and stable operation of the mechanism. It can adapt to the spraying of various materials such as coarse salt, fine salt, snow melting agent, dry sand, etc., and meet different snow conditions and road requirements. The spreading machine adopts a scraper chain conveying method, which ensures smooth and residue free feeding. The tail is equipped with a 500mm stainless steel throwing plate, which is resistant to salt and alkali corrosion and has a long service life. The spreading parameters can be flexibly adjusted, and the spreading width can be adjusted from 2-12 meters. The spreading amount is controlled between 20-150g/m ², and the working speed can be adjusted from 5-45km/h. This ensures that the snow melting agent is evenly spread, quickly melts the snow on the road surface, prevents icing, and balances snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal operations and is suitable for various winter snow scene treatments.
