I. Scenario Introduction: The 'Long-Standing Challenge' of Sewer Cleaning in a District of Yangzhou In summer 2024, Yangzhou experienced consecutive heavy rainfall, causing poor drainage and manhole overflow in multiple low-lying urban areas. During the flood-prevention summary meeting, the deputy head of the municipal sanitation department of a district in Yangzhou (hereinafter referred to as 'the Department') stated frankly: 'Our existing large-scale vacuum trucks cannot access narrow alleys and back streets; manual cleaning is inefficient. We must procure a batch of flexible, community-accessible small-scale sewer cleaning equipment.' This requirement directly triggered the current procurement project—the Dongfeng double-cab, blue license plate, 3-cubic-meter sewer cleaning truck. Preliminary internal research by the Department revealed that 3-cubic-meter sewer cleaning trucks on the market are mainly categorized into 'single-row cab' and 'double-row cab' types. Single-row cabs offer limited cabin space and cannot accommodate more than two operators, whereas double-row cabs seat up to five personnel—better fulfilling the 'multi-purpose vehicle' requirement. Ultimately, leadership approved procurement of Dongfeng double-row chassis-based, blue license plate (drivable with C1 driver’s license), 3-cubic-meter capacity sewer cleaning trucks. Based on local 2024 procurement benchmarks for similar vehicles, the budget was set at approximately RMB 120,000–150,000 per unit. II. Internal Vehicle Selection: Comparison of Three Mainstream Options The Department’s Equipment Division compiled three candidate models—all built on Dongfeng double-row chassis—with the following parameter comparison (data source: MIIT announcements and Chengli Special Purpose Vehicle product database): Comparison Item | Option A (Chengli CLW5040TQYD6) | Option B (Brand X JX5040TQY) | Option C (Brand Y BJ5040TQY) ---|---|---|--- Chassis Model | Dongfeng EQ1045SJ16DC | Jiangling JX1041TSG26 | Foton BJ1045V9JB5-54 Engine Power | 70 kW (95 HP) | 85 kW (116 HP) | 70 kW (95 HP) Effective Tank Capacity | 3.0 m³ | 2.8 m³ | 3.0 m³ Rated Occupancy (Cab) | 2+3 persons | 2+3 persons | 2+2 persons Upper-Structure Configuration (Sewer Cleaning Functions) | Hydraulic Grab Bucket + High-Pressure Cleaning + Wastewater Tank | Hydraulic Grab Bucket + Wastewater Tank | Hydraulic Grab Bucket + High-Pressure Cleaning Reference Unit Price (RMB 10,000, tax-inclusive) | ~138,000 | ~152,000 | ~145,000 National Registration & Annual Inspection | Full MIIT announcement compliance; normal registration permitted | Full MIIT announcement compliance | Full MIIT announcement compliance Note: Above prices refer to publicly disclosed tender information and Chengli Special Purpose Vehicle’s 2024 quotation list. Actual transaction prices may vary depending on configuration, region, and bulk procurement terms. The Department’s Equipment Division focused analysis on three key aspects: 1. Functional Completeness: Option A (Chengli) integrates all three core functions—hydraulic grab bucket (for removing sediment from manholes), high-pressure cleaning (for pipe clearance), and wastewater tank (for sewage collection)—enabling integrated 'cleaning-washing-vacuuming' operations. In contrast, Option B lacks high-pressure cleaning, while Option C lacks a wastewater tank, rendering them incapable of full-cycle integrated operation. 2. Cab Space: Option C accommodates only four persons; additional transport would be required for crew members, increasing hidden operational costs. Options A and B both seat five, offering greater practicality. 3. After-Sales Service: Chengli provides 'nationwide chassis warranty + lifetime upper-structure service', with a commitment to dispatch spare parts within 24 hours—a critical advantage for municipal authorities, where rapid fault response directly impacts flood prevention effectiveness.
