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 of 10-12 cubic meters, it is made of high-strength carbon steel plates with "four edges and five bottoms". The top is equipped with a rainproof cover, which can effectively prevent the snow melting agent from getting wet and solidifying. The silo has undergone special anti-corrosion treatment, is resistant to salt and alkali corrosion, has a long service life, and is suitable for long-term outdoor winter operations. 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 spreader can be powered by a chassis or an independent diesel/gasoline engine, which does not interfere with the vehicle's driving system. The material is conveyed by a scraper, ensuring smooth and residue free feeding. The spreader has a diameter of 550mm, can be folded and flipped, and is easy to transfer and store. The spreading parameters can be flexibly adjusted, and the spreading width can be adjusted from 2-15 meters. The salt spreading amount can be controlled between 20-300g/m ², and the working speed can be adjusted from 5-45km/h. It can achieve uniform spreading through precise adjustment, quickly melt snow on the road surface, prevent icing, and balance snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal operations.
