As an 18 ton heavy-duty professional snow removal vehicle under the Chengli brand, 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 a snow melting agent spreading machine, mainly used for snow removal and melting operations on winter roads. It is equipped with an 8-cubic meter large capacity V-shaped material bin, made of carbon steel plate, and treated with three-level anti-corrosion spray coating. It is resistant to salt and alkali corrosion, has a long service life, and is equipped with a rain cover and a high toughness protective cover on the top, which can effectively prevent the snow melting agent from getting wet and solidifying, 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 spreading system. It can adapt to various materials such as coarse salt, fine salt, snow melting agent, and dry sand for spreading, and can adapt to different snow conditions and road surface requirements. Snow melting agent can be pre sprinkled on dangerous road sections before snowfall to prevent road icing in advance. The spreading system adopts a scraper chain conveying method, which ensures smooth and residue free feeding. It is equipped with a 304 stainless steel folding spreading disc, which is convenient for transfer and storage. The spreading parameters can be flexibly adjusted, and the spreading width can be adjusted from 2-15 meters. The spreading amount is controlled between 20-150g/m ², and the working speed can be adjusted from 15-40km/h. The spreading material is not controlled by the vehicle speed, and the spreading amount is accurately controlled through an intelligent adjustment knob to ensure that the snow melting agent is evenly spread, quickly melts the snow on the road surface, prevents icing, and balances the snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal operations, adapt to various winter snow accumulation scenarios, and the spreading machine can be disassembled as a whole. It can be conveniently stored in non operating states without affecting the normal passage of vehicles.
