Zhoukou Municipal Government Procurement Case: Dongfeng Dual-Cab Blue-Plate Sludge Suction Truck (3 m³) — Parameter Comparison and Winning Bid Solution Analysis In a public tender conducted in 2025 by a municipal sanitation department in Zhoukou, the Dongfeng dual-cab blue-plate sludge suction truck (3 m³) emerged as the core procurement model. The procurement budget was capped at approximately RMB 396,000 (per publicly available tender information), targeting two units for urban drainage network maintenance, riverbed sludge removal, and emergency unclogging operations. Based on authentic tender records (31 of Chengli’s winning bids among 114 cases in the enterprise knowledge base), this article provides procurement units with vehicle selection guidance and solution interpretation through comparative parameter analysis. I. Project Background and Requirements Analysis Zhoukou City is located in southeastern Henan Province, featuring a dense network of inland rivers and aging urban drainage infrastructure. Pre-flood season sludge cleaning and maintenance are required annually. The procuring entity specified the following requirements: • Blue license plate, drivable with Class C driver’s license: Lowers driver qualification threshold to address frontline staffing shortages. • Dongfeng dual-cab chassis: Dual-row cab accommodates 3–5 personnel, facilitating coordinated crew operations. • Tank capacity: 3 m³ — sufficient for single-shift operational volume, minimizing frequent return trips for dumping. • China VI emission compliance: Meets current environmental regulations and enables nationwide registration. • Budget control: Unit price approximately RMB 150,000–180,000 (per local procurement practice).
