As a 25 ton heavy-duty professional snow removal vehicle under the Chengli brand, 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 conditions and road icing in urban main roads, highways, large parks, etc. The dedicated device is a snow melting agent spreading machine, mainly used for snow removal, ice breaking, and snow melting agent spreading operations on winter roads. It is equipped with a 12 cubic meter large capacity V-shaped material bin, made of high-strength carbon steel plates with "four edges and five bottoms", and has a rainproof cover and high toughness protective cover on the top, which can effectively prevent the snow melting agent from being damp and compacted. The material bin is treated with three-level anti-corrosion spraying, resistant to salt and alkali corrosion, and has a long service life, 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, ensuring smooth and residue free feeding. It is equipped with a stainless steel corrosion-resistant throwing disc, which can be folded and flipped for convenient 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 uniform spreading of snow melting agent, quickly melting snow on the road surface, breaking thin ice, and balancing snow melting effect and environmental protection. It can meet the efficient needs of large-scale snow removal operations and adapt to various winter snow and ice accumulation scenarios.
