Jinhua Dongfeng D6 Blue-Plate 3 m³ Sludge Tipper Truck Government Procurement Case and Bid-Winning Solution Analysis In the municipal sanitation sector, sludge transportation remains one of the most challenging tasks. Particularly in medium- and small-sized cities or township streets, daily sludge generation is modest, yet collection frequency is high—placing stringent demands on vehicle maneuverability and economic efficiency. Recently, a municipal sanitation department in Jinhua procured a Dongfeng D6 blue-plate 3 m³ sludge tipper truck for sludge removal within its jurisdiction. Based on this authentic procurement case, this article comprehensively analyzes the procurement background, configuration plan, price comparison, and Chengli Special Purpose Vehicle Co., Ltd.’s service advantages—providing practical reference for users with similar requirements. I. Procurement Background and Needs Analysis A municipal sanitation department in Jinhua is responsible for sludge removal from local wastewater treatment plants and sewer networks. Its existing transport vehicles were predominantly yellow-plate models, presenting the following pain points: • Restricted Road Access: Yellow-plate vehicles face traffic restrictions on certain urban roads, impairing operational efficiency. • Higher Operating Costs: Higher acquisition costs and stricter driver licensing requirements (Class B2 or above) increase personnel-related expenses. • Mismatched Capacity: Daily sludge generation averages 3–5 m³; large-capacity vehicles result in excessive single-trip capacity and resource wastage. To address these issues, the department decided to procure a blue-plate sludge tipper truck meeting the following criteria: operable with a Class C1 driver’s license; gross vehicle weight not exceeding 4.5 tons; cargo body volume of 3 m³; excellent sealing performance and efficient unloading capability; and a budget capped at approximately RMB 137,000 (based on publicly available tender information). After comprehensive evaluation and on-site inspections, the department selected Chengli Special Purpose Vehicle Co., Ltd.’s customized Dongfeng D6 chassis solution. This vehicle carries the official model number CLW5040ZXXD6, fully complies with China VI emission standards, features nationwide Dongfeng chassis warranty, and offers lifetime after-sales support for the superstructure provided by Chengli. II. Configuration Plan and Key Advantages Per Chengli Special Purpose Vehicle’s proposal, the main specifications of the Dongfeng D6 blue-plate 3 m³ sludge tipper truck are as follows: Configuration Item Detailed Specifications Remarks Chassis Model Dongfeng D6 (White) China VI compliant; operable with Class C1 license Engine Quanchai 95 HP Sufficient power for urban transport Transmission 5-speed manual Simple operation, adaptable to diverse road conditions Body Volume 3 m³ Optimally matched to daily sludge volume, avoiding waste Sealing Method Hydraulic lifting + rear cover hydraulic locking Prevents spillage and leakage during transit Unloading Method Hydraulic self-dumping High unloading efficiency, reduces manual labor Tires 6.50R16 steel-belted radial tires High load-bearing capacity Reference Landed Price Approx. RMB 105,000–118,000 Tax-inclusive; based on publicly available tender data Key advantages of this solution include: • Blue-Plate Advantage: Operable with a Class C1 license—ensuring unrestricted urban access and reducing driver recruitment difficulty and associated costs. • Cost Efficiency: Acquisition cost is approximately RMB 30,000–50,000 lower than yellow-plate alternatives (per local procurement practice), with lower fuel consumption. • Superior Sealing Performance: Hydraulic rear-cover locking design effectively prevents sludge leakage and odor dispersion during transport—fully compliant with environmental protection requirements. • High Unloading Efficiency: Simple-to-operate hydraulic dumping system completes each unloading cycle in ju
