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 such as urban main roads, highways, and large parks. The dedicated device is the snow melting and spreading system, which is one of the core equipment for ensuring smooth winter roads. It is equipped with a large capacity V-shaped material bin and is made of high-strength steel plates. The overall rigidity is good and not easy to deform, which can effectively prevent the snow melting agent from getting wet and solidifying. A filter screen is placed on the material bin to intercept large particles of debris, avoid equipment jamming, and ensure the safe and stable operation of the spreading system. It is suitable for spreading various materials such as coarse salt, fine salt, snow melting agent, and dry sand, and is adaptable to different types of materials. Snow conditions and road surface requirements. The spreading system adopts a scraper chain conveying method, which ensures smooth and residue free feeding. It is equipped with corrosion-resistant throwing discs, and the spreading parameters can be flexibly adjusted. The spreading width can be adjusted from 2-12 meters, and the spreading amount can be precisely controlled. The working speed can be adjusted from 5-45 km/h. The spreading material is not controlled by the vehicle speed and is completely independent, ensuring that the snow melting agent is evenly spread, quickly melting the snow on the road surface, preventing icing, and balancing the snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal industry.
