As an 18 ton heavy-duty professional snow removal vehicle, its core function is to carry out large-scale snow melting and ice breaking operations in winter. It focuses on efficient snow 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 a spreader, mainly used for snow removal, ice breaking, and snow spreading operations on winter roads. It is equipped with a large capacity V-shaped material bin, which is made of high-strength steel plates and folded into shape. The overall rigidity is good and not easy to deform, which can effectively prevent the snow melting agent from becoming damp and compacted. 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. Adapting to different snow conditions and road surface requirements, snow melting agents can be pre sprayed on dangerous road sections before snowfall to prevent road icing. The spreading system adopts a scraper chain conveying method, ensuring 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 spreads evenly, quickly melts the snow on the road surface, breaks the thin ice, and balances the snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal industry and is suitable for various winter snow and ice scene disposal.
