Xianyang Municipal Government Procurement Case: Upgrading Outdated Equipment and Analysis of the Winning Bid Solution In municipal sanitation, sewer cleaning trucks serve as core equipment for unblocking and cleaning drainage pipelines; their performance directly impacts urban flood prevention and drainage efficiency. In 2025, a municipal sanitation department in Xianyang launched a procurement project to address key pain points of aging sewer cleaning trucks—including low operational efficiency, non-compliant emissions, and high maintenance costs—and ultimately selected Chengli Special Purpose Vehicle’s Dongfeng dual-cab sewer cleaning truck (blue license plate, 3 m³). This article comprehensively analyzes the case—from needs assessment and solution alignment to delivery and FAQs. I. Pain Points of Aging Equipment: Dual Pressure on Efficiency and Environmental Compliance The unit previously operated three sewer cleaning trucks, all over eight years old, suffering from the following issues: • Non-Compliant Emissions: Original vehicles met only China III emission standards and failed to comply with the mandatory China VI regulations, facing imminent phase-out. • Low Operational Efficiency: Equipped with outdated hydraulic systems, resulting in prolonged single-cycle cleaning operations and frequent failures such as hydraulic oil leakage and blockages. • High Maintenance Costs: Chassis components were discontinued; average repair turnaround time reached 15–20 days, severely disrupting routine operations. • Limited Cabin Space: Older models featured single-row cabs accommodating only two occupants—insufficient for team-based field operations. According to feedback from the unit’s Equipment Department head: “During the summer 2024 heavy rainfall events, sewer truck failures caused poor drainage at three road sections, forcing us to rent external equipment to resolve the situation.” Aging equipment had significantly undermined emergency response capability. II. New Requirements Assessment: Blue License Plate, Dual-Row Cab, and 3 m³ Capacity as Key Criteria Based on the above challenges, the unit issued its procurement requirements in early 2025, with the following core specifications: • Emission Standard: Must meet China VI standards to ensure nationwide registration eligibility and annual inspection compliance. • Payload & Tank Capacity: Effective tank volume approximately 3 m³—sufficient for daily cleaning tasks while retaining blue license plate classification (drivable with C1 driver’s license). • Cab Configuration: Dual-row seating for up to five occupants, enabling coordinated team operations. • Chassis Brand Preference: Dongfeng series—valued for broad parts interchangeability and comprehensive after-sales service network. • Budget Control: Based on publicly available tender data, per-unit budget capped at approximately RMB 135,000–169,000 (inclusive of purchase tax and registration fees). During the evaluation process, the unit compared chassis options from Dongfeng, Sinotruk, and Foton. Dongfeng was prioritized due to its high market penetration, cost-effective spare parts, and strong aftermarket support. Suppliers were also required to provide complete MIIT (Ministry of Industry and Information Technology) announcement parameters to guarantee legal registration and licensing. III. Chengli’s Tailored Solution: In-Depth Analysis of CLW5040TQZD6 Sewer Cleaning Truck Chengli Special Purpose Vehicle proposed the CLW5040TQZD6 sewer cleaning truck—custom-built on a Dongfeng chassis—to precisely match the user’s requirements. This model fully aligns with the procurement criteria in terms of official MIIT parameters, configuration, and after-sales service.
