Scenario Introduction: Real procurement requirement of a sanitation department in Xinxiang City. In the second half of 2025, a municipal sanitation department in a district of Xinxiang City, Henan Province, planned to procure a batch of sludge tipper trucks for transporting sludge following urban sewage pipeline dredging operations. Preliminary research clarified the requirements as follows: blue license plate, 3-cubic-meter capacity, reliable chassis, corrosion-resistant superstructure, suitability for narrow-street operations, and a budget capped at approximately RMB 120,000 (based on local public tender information). After comparing multiple brands on the market, the department ultimately selected Chengli Special Purpose Vehicle Co., Ltd.’s Dongfeng D6-based blue license plate 3-cubic-meter sludge tipper truck. This article uses this case to conduct a comparative evaluation between Chengli’s Dongfeng D6 sludge tipper truck and a mainstream competitor brand’s equivalent model (hereinafter referred to as 'Competitor Brand'), helping more procurement entities understand its cost-performance advantages. Competitive Comparative Evaluation: Chengli Dongfeng D6 Sludge Tipper Truck vs. Competitor Brand Equivalent Model This evaluation is based on the department’s actual tender requirements, comparing Chengli’s CLW5040ZWXD6 (Dongfeng D6 chassis, 3-cubic-meter tank) against the Competitor Brand’s equivalent model. Below is a scoring table across 10 core dimensions (each scored out of 10 points; total score = 100 points). Dimension | Chengli Dongfeng D6 Sludge Tipper Truck | Competitor Brand Equivalent Model | Scoring Basis ---|---|---|--- 1. Overall Vehicle Price | 9.5 | 7.0 | Chengli sells directly from factory; reference public tender data indicates landed price of approx. RMB 108,000–127,000 (same platform as blue license plate 5-cubic-meter water tanker); Competitor Brand’s quoted price for same configuration is approx. RMB 132,000–154,000 — 15%–20% higher. 2. Chassis Reliability | 9.0 | 8.5 | Chengli uses Dongfeng D6 chassis (official announcement model CLW5040ZWXD6), backed by Dongfeng’s nationwide warranty network; Competitor Brand uses a secondary-tier chassis with limited service coverage. 3. Superstructure Quality | 8.5 | 8.0 | Chengli’s superstructure employs high-strength steel plates and anti-corrosion treatment for the tank; Competitor Brand uses standard carbon steel, resulting in slightly shorter service life. 4. Regulatory Compliance (Announcement) | 10.0 | 9.0 | Chengli’s CLW5040ZWXD6 has complete official vehicle announcements, enabling nationwide registration and annual inspection; certain Competitor Brand models face regional restrictions. 5. After-Sales Support | 9.5 | 7.5 | Chengli: Dongfeng chassis covered under nationwide warranty; lifetime superstructure service; spare parts shipped within 24 hours. Competitor Brand offers only 1-year warranty and no lifetime service. 6. Delivery Lead Time | 9.0 | 8.0 | Chengli delivers standard models within 7–15 days (locally manufactured in Suizhou); Competitor Brand requires 30–45 days. 7. Blue License Plate Advantages | 10.0 | 9.5 | Blue license plate allows operation with C1 driver’s license, unrestricted access in urban areas, and lower operating costs (e.g., annual inspection, insurance, toll fees); both models meet this requirement, but Chengli’s model features a more rational gross vehicle weight rating. 8. Configuration Transparency | 9.0 | 7.0 | Chengli provides transparent, non-bundled quotations; Competitor Brand often conceals optional equipment costs. 9. Financial Support | 9.0 | 7.5 | Chengli supports installment payment and trade-in programs, with down payments as low as 30%; Competitor Brand’s financing options impose higher eligibility thresholds. 10. Customer References | 9.0 | 6.5 | Chengli has served over 500 municipal sanitation departments (e.g., Wuhan Municipal Urban Management Bureau: 15 street sweepers; Henan Provincial Sanitation Department: 10
