Case Study and Bid-winning Solution Analysis: Blue License Plate, 3-cubic-meter Dongfeng D6 Sludge Tipper Trucks for Government Procurement in Ganzhou City. As urban environmental governance standards continue to rise, sludge transportation and disposal have become critical issues for municipal sanitation departments. Recently, a municipal sanitation department in Ganzhou City publicly tendered for a batch of Dongfeng D6 blue license plate, 3-cubic-meter sludge tipper trucks to meet demands for sewer network desilting and sludge transfer within its jurisdiction. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli Special Purpose Vehicle') successfully delivered the vehicles, leveraging its mature product solutions and comprehensive after-sales service. This article provides an in-depth analysis of the procurement project’s background, vehicle configuration, competitive advantages of the winning bid, and addresses frequently asked questions for reference by procuring entities. I. Project Background and Requirements Analysis During the implementation of stormwater-sewage separation retrofitting and routine pipeline maintenance, a municipal sanitation department in Ganzhou City identified aging transport vehicles with non-compliant emissions and insufficient loading capacity. According to publicly released tender information, the project budget was capped at approximately RMB 344,000, with plans to procure four blue license plate sludge tipper trucks. Key requirements included: • Chassis Compliance: Compliant with China VI emission standards; operable with a Class C driver’s license (blue license plate), enabling flexible dispatch. • Loading Capacity: Effective volume of approximately 3 cubic meters, suitable for neighborhood sewer network desilting and sludge transfer from small-scale wastewater treatment stations. • Sealing Performance: Fully enclosed cargo body to prevent sludge leakage and odor dispersion during transport, meeting environmental protection requirements. • Durability: Proven chassis platform ensuring reliable performance on both urban roads and partially unpaved surfaces. Ultimately, Chengli Special Purpose Vehicle’s integrated solution—Dongfeng D6 chassis paired with Chengli proprietary superstructure—stood out among competitors, delivering four units of model CLW5070GSSD6 sludge tipper trucks at a unit price of approximately RMB 75,000 (based on publicly available tender data). II. Vehicle Configuration and Technical Specifications The delivered vehicles are built upon the Dongfeng D6 single-row cab chassis, equipped with Yunnan Internal Combustion Engine or Yuchai engines (95–110 hp), mated to a 5-speed manual transmission.
