Government Procurement Case and Chassis Selection Analysis for the Wuhan Dongfeng Dual-Cab Sewer Cleaning Truck (Blue License Plate, ~3 m³ Capacity) In urban drainage network maintenance, sewer cleaning trucks are essential equipment for municipal sanitation departments. Recently, the Urban Management Bureau of a district in Wuhan City conducted a public tender for a batch of Dongfeng dual-cab sewer cleaning trucks (blue license plate, ~3 m³ capacity). Based on this case, this article provides an in-depth interpretation of the procurement plan—from chassis selection, load-bearing capability and passability, maintenance convenience, to Chengli’s flagship models—to serve as a reference for similar tenders. Procurement Background and Requirements Analysis This procurement project was initiated by the Urban Management Bureau of a district in Wuhan City, primarily intended for sludge removal operations from rainwater and sewage manholes and pipelines within its jurisdiction. The procurement budget is approximately RMB 341,000 (per publicly available tender information), targeting two blue-license-plate, 3-cubic-meter sewer cleaning trucks. Key requirements include: • Chassis Type: Dongfeng dual-cab configuration, enabling transport of 2–3 operators. • Capacity Requirement: Approximately 3 cubic meters, sufficient for routine sludge removal volumes. • Road Access Constraints: Blue license plate classification, operable with a Class C driver’s license; suitable for narrow urban roads. • Emission Standard: China VI compliant, meeting Wuhan’s environmental regulations. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. was shortlisted due to its superior chassis compatibility and overall cost-effectiveness. Chassis Selection: Comparative Analysis of Dongfeng, Sinotruk, Foton, and FAW Chassis selection significantly impacts vehicle maneuverability, load-bearing capacity, and long-term serviceability.
