Deyang Sinotruk Sludge Self-Dumping Truck (24 m³) Government Procurement Case: Bid Quotation and Winning Proposal Analysis In the municipal sanitation sector, sludge transport trucks are core equipment ensuring efficient operations at wastewater treatment plants and pipeline desilting sites. In 2025, a municipal sanitation department in Deyang, Sichuan Province, procured a batch of 24 m³ Sinotruk-chassis sludge self-dumping trucks via public tender to replace aging vehicles and enhance hauling efficiency. This article analyzes Chengli Special Purpose Vehicle Co., Ltd.’s practical application and competitive advantages in such projects, from perspectives including residual value retention, configuration comparison, and cost control. I. Project Background and Procurement Requirements This procurement project was initiated by the Urban Management Bureau of a district in Deyang, with a budget capped at approximately RMB 5.126 million (per publicly available tender information), aiming to acquire 10 units of 24 m³ sludge self-dumping trucks. Key requirements included: chassis brand must be Sinotruk (to ensure compatibility with local road conditions and after-sales service network); cargo body volume strictly limited to 24 cubic meters; leak-proof, sealed design; full compliance with China VI emission standards. Additionally, the procuring entity explicitly stipulated residual value expectations after three years to minimize total lifecycle costs. In the public tender process, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) secured the contract by leveraging its mature chassis integration solutions, high-residual-value vehicle configurations, and rapid delivery capability enabled by local manufacturing in Suizhou—ultimately delivering 10 units of Sinotruk-chassis, 24 m³ sludge self-dumping trucks. Customer feedback indicates that since commissioning in May 2025, these vehicles have achieved an average daily sludge haulage volume of approximately 80 tons, with failure rates below the industry average. II. Resale Market Value After Three Years and Residual Value Comparison for Chengli Models Vehicle residual value represents a hidden cost in government procurement decisions. Based on Chengli’s historical data and industry research, the resale market price for a 24 m³ Sinotruk-chassis sludge self-dumping truck after three years is approximately 65%–75% of its ex-factory new vehicle price (per publicly available tender information and industry experience). For this batch, the ex-factory unit price was approximately RMB 420,000 (per publicly available tender information), yielding an estimated residual value of RMB 270,000–310,000 after three years. Compared with competing products, Chengli models demonstrate clear residual value advantages: • Chassis Universality: Sinotruk chassis are supported by over 3,000 authorized service stations nationwide, ensuring high parts availability and broader buyer acceptance—directly boosting residual value. • Body Reliability: Chengli’s 24 m³ sludge self-dumping bodies employ high-strength steel plates with anti-corrosion treatment, requiring no major repairs within three years—reducing depreciation discounts during second-hand transactions. • Complete Regulatory Approvals: All models (e.g., CLW5180GSSD6) possess full official type-approval documentation, enabling nationwide registration and annual inspection—avoiding transfer complications due to emission or dimensional noncompliance. III. Key Configurations Affecting Residual Value and Selection Recommendations Procuring entities should prioritize the following configuration factors when evaluating residual value impact: Configuration Dimension | High-Residual-Value Configuration | Low-Residual-Value Configuration | Chengli Recommended Solution Chassis Brand | Mainstream brands (e.g., Sinotruk, Dongfeng) | Niche or regionally restricted brands | Sinotruk chassis (nationwide authorized service network) Body Mate
