As a 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, airport runways, etc. The dedicated device is a spreading machine, which is one of the core equipment for ensuring smooth winter roads. Equipped with a large capacity V-shaped silo with a capacity of up to 8 cubic meters, it is made of high-strength carbon steel plate and treated with special baking paint. The structure is simple and reliable, and it can achieve automatic snow melting agent feeding and completely residue free discharge, effectively reducing material waste and equipment blockage, and lowering maintenance costs. A filter screen is installed 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 various materials such as coarse salt, fine salt, snow melting agent, dry sand, etc., and is suitable for different snow conditions and road surface requirements. The spreading parameters can be flexibly adjusted, with a spreading width of 2-15 meters, a salt spraying amount controlled between 20-300g/m ², and a working speed adjustable between 5-45km/h. The spreading plate is made of 304 stainless steel material, which is resistant to salt and alkali corrosion, and is equipped with a dedicated transmission mechanism to ensure uniform spreading of snow melting agent, quickly melting snow on the road surface, preventing icing, and balancing snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal operations.
