Government Procurement Case and Model Selection Analysis of the Jiujiang Dongfeng D6 Blue License Plate 3-Cubic-Meter Sludge Tipper Truck. In autumn 2025, a municipal sanitation department in a district of Jiujiang City, Jiangxi Province, launched a sludge transport vehicle renewal project, planning to procure a batch of blue license plate, 3-cubic-meter sludge tipper trucks for urban pipeline desilting and sludge transportation from wastewater treatment plants. After comprehensive evaluation and on-site inspections, the department selected the CLW5040ZWXD6 sludge tipper truck built by Chengli Special Purpose Vehicle Co., Ltd. on the Dongfeng D6 chassis, with a total delivery of four units. This article analyzes the government procurement decision logic through parameter comparison and scenario analysis. I. Project Background and Requirements The department’s existing sludge trucks were outdated and failed to meet current emission standards, necessitating urgent replacement. Core requirements included: - Vehicles must comply with blue license plate regulations and be operable by drivers holding a Class C driver’s license, enabling flexible personnel allocation; - Cargo box capacity should be approximately 3 cubic meters to meet daily desilting and short-haul transportation needs; - Chassis must be reliable and durable, with robust after-sales service support; - Unit price must remain within budget constraints; based on local procurement practices, the target range was RMB 95,000–115,000 per unit. II. Horizontal Parameter Comparison Across Five Mainstream Models The procurement team conducted a technical review of five mainstream blue license plate, 3-cubic-meter sludge tipper truck models available on the market. The comparative table below summarizes key specifications (data sourced from MIIT announcements and publicly available documentation): Parameter Dimension | Chengli CLW5040ZWXD6 (Dongfeng D6 Chassis) | Brand B Model (Foton Chassis) | Brand C Model (JAC Chassis) | Brand D Model (Dongfeng Xiaobawang Chassis) | Brand E Model (Wuzheng Chassis) ---|---|---|---|---|--- Chassis Model | EQ1045SJ3CDF | BJ1045V9JB5-54 | HFC1042P31K1C7S | EQ1040SJ20DC | WZ1040S-1 Engine Model | Q23-115E60 (115 HP) | D20TCIF1 (116 HP) | HFC4DB3-2E (120 HP) | Q23-95E60 (95 HP) | CA4DB1-11E6 (110 HP) Emission Standard | China VI | China VI | China VI | China VI | China VI Transmission | 5-speed manual | 5-speed manual | 5-speed manual | 5-speed manual | 5-speed manual Cargo Box Volume | 3 m³ | 3 m³ | 2.8 m³ | 3.2 m³ | 3 m³ Tire Specification | 7.00R16LT | 7.00R16LT | 7.00R16LT | 6.50R16LT | 7.00R16LT Wheelbase (mm) | 3,308 | 3,360 | 3,308 | 3,300 | 3,300 Curb Weight (kg) | ~3,150 | ~3,200 | ~3,100 | ~3,050 | ~3,250 Superstructure Configuration | Hydraulic tipping + sealed cover | Hydraulic tipping + sealed cover | Hydraulic tipping + sealed cover | Hydraulic tipping + sealed cover | Hydraulic tipping + sealed cover Reference Price (RMB 10,000s) | ~105,000–115,000 | ~100,000–120,000 | ~95,000–110,000 | ~90,000–105,000 | ~85,000–100,000 After-Sales Service | Nationwide Dongfeng chassis warranty + lifetime superstructure service | Chassis: 3 years / 100,000 km | Chassis: 3 years
