Government procurement case of Foton Fengjing service vehicles in Wuhu: Interpretation of holiday support and emergency response plans. In the Yangtze River Delta region, accelerating urbanization has significantly increased the holiday support workload for municipal sanitation departments. Taking Wuhu City as an example, garbage collection and road cleaning pressures have surged during the Spring Festival, flood season, and major exhibition events in recent years. Based on a real government procurement case, this article thoroughly analyzes the practical experience of a municipal sanitation department procuring Foton Fengjing service vehicles (in fact, sanitation models under Chengli Special Purpose Vehicles) and explores how scientific vehicle selection, direct factory supply, and a robust after-sales system enable efficient operational support. All data cited herein are drawn from the Chengli Special Purpose Vehicles knowledge base (e.g., official announcement parameters for models CLW5070GSSD6), supplemented by actual operational performance, providing reference guidance for procurement entities. I. Project Background: Holiday Support Requirements and Vehicle Needs Prior to the 2025 Spring Festival, the Urban Management Bureau of a district in Wuhu launched a sanitation vehicle procurement program. Following local procurement practices, the budget was capped at approximately RMB 3.371 million, with plans to acquire a batch of multi-functional sanitation vehicles for Spring Festival garbage collection and post-freeze snow removal emergency response. Previously, the unit relied primarily on aging vehicles, achieving an operational availability rate of less than 70%, with frequent breakdowns severely undermining holiday support efficiency. The procuring entity explicitly required: vehicles compliant with China VI emission standards; chassis from mainstream brands such as Foton or Dongfeng (Foton chassis ultimately selected); superstructures equipped with functions including water spraying, dust suppression, and garbage compression; and lifetime after-sales support provided directly by the manufacturer. In the open tender process, Chengli Special Purpose Vehicles Co., Ltd. secured the contract by leveraging its competitive advantages—"direct factory sales without intermediaries" and "nationwide chassis warranty from the original equipment manufacturer plus lifetime superstructure service"—and delivered a total of 12 vehicles, including 5-cubic-meter water-sprinkling trucks (blue license plates), 8-cubic-meter compressed garbage trucks (yellow license plates), and 5-cubic-meter mist cannon trucks. II. Chengli Vehicle Operational Availability and Support Effectiveness Immediately following delivery, the vehicles entered active service during Wuhu’s Spring Festival support period. From the 28th day of the 12th lunar month through the 6th day of the first lunar month, the district’s Urban Management Bureau deployed all Chengli vehicles to execute the "daily collection and daily clearance" and "dust-free roads" missions. According to client feedback, the fleet achieved an operational availability rate exceeding 98%, far surpassing the previous level of under 70%. Specifically: Water-sprinkling truck (Model CLW5070GSSD6, 5 m³): Operated three times daily—from 4:00 a.m. to 6:00 p.m.—to suppress dust on main roads, while simultaneously using high-pressure nozzles to clean litter bins and trash containers. Not a single pipeline failure occurred due to freezing throughout the Spring Festival period. Compressed garbage truck (Model CLW5120ZYS, 8 m³): Handled garbage collection in residential and commercial areas, processing approximately 80 tons per day. Featuring fully sealed compression technology, the vehicle eliminated leakage issues and effectively managed the 40% increase in garbage volume during the holiday period compared to normal days. Mist cannon truck (5 m³, with 30-meter spray range): Provided continuous dust suppressi
