In-depth interpretation of the government procurement case and winning bid solution for Ford Transit V362 service vehicles in Jingzhou. In government procurement, service vehicles—critical tools for urban management, emergency response, and sanitation operations—directly impact operational efficiency and budget control. In 2024, a municipal sanitation department in Jingzhou planned to procure a batch of service vehicles for daily inspections, equipment transportation, and emergency response. After multiple rounds of evaluation, it selected Chengli service vehicles built on the Ford Transit V362 chassis. This article uses this case as a starting point—from cargo volume selection and daily workload calculation to practical matching—to provide a detailed, scientific procurement guide. I. Case Background: Procurement Requirements of a Municipal Sanitation Department in Jingzhou This department is primarily responsible for road cleaning, garbage collection, and emergency repairs across approximately 50 km² of urban area. Its existing fleet has severely aged, resulting in high maintenance costs; therefore, it needs to replace 10–15 multi-functional service vehicles. Key requirements include: • Daily inspections: average daily mileage of 80–120 km, requiring toolboxes and inspection equipment; • Small-scale material transport: e.g., cleaning tools and emergency supplies (net weight ≤1.5 tons); • Emergency response: rapid reconfiguration into temporary command or rescue platforms. Following a public tender process, Chengli Special Purpose Vehicle Co., Ltd. won the bid with its competitive advantages—including factory-backed warranty for the chassis and lifetime after-sales service for the bodywork—and delivered 12 Ford Transit V362-based service vehicles at an approximate unit price of RMB 150,000–180,000 (based on publicly available tender information). The vehicles have been in operation for six months, with customer feedback highlighting “high reliability, low fuel consumption, and excellent space utilization.” II. Cargo Volume Selection: How to Choose Among 3 m³, 5 m³, 8 m³, and 12 m³ Models? Cargo volume directly determines a service vehicle’s operational capability. According to our product database, Chengli offers models ranging from 3 m³ to 12 m³, covering both light-duty (blue-plate) and medium-duty (yellow-plate) classifications. Below is the volume-selection logic derived from the Jingzhou case: • 3 m³ model (blue-plate): Ideal for narrow urban street patrols and small equipment transport. Example: CLW5040XXH, with a cargo box volume of ~3 m³, capable of carrying loads under 1 ton. Used by the Jingzhou department for community-level inspections; drivable with a Class C1 driver’s license, offering high maneuverability. • 5 m³ model (blue-plate): Balances cargo capacity and road accessibility. Comparable blue-plate 5 m³ water-sprinkling trucks are priced at ~RMB 98,000–115,000; service vehicles fall within a similar range. The Jingzhou department procured four 5 m³ units for routine tool transport and emergency supply storage. • 8 m³ model (yellow-plate): Suitable for medium-distance transport and large equipment handling. Example: CLW5080XXH, with an 8 m³ cargo volume, capable of carrying 2–3 tons. Deployed by Jingzhou for cross-district support missions; requires a Class B2 driver’s license. • 12 m³ model (yellow-plate): High-capacity configuration, typically used for bulk material transport or mobile command centers. Jingzhou procured only one such unit for major event support. Selection Recommendation: For predominantly urban operations, prioritize blue-plate 3–5 m³ models; for suburban/county-level coverage or high-volume transport, select yellow-plate 8–12 m³ models. Chengli supports full customization, with chassis options including Dongfeng and Ford, complete official announcements (Type Approval), and nationwide registration eligibility. III.
