Procurement Background: Upgraded Sewer Cleaning Requirements in Weifang Urban Area. In early 2025, a municipal sanitation department in Weifang City initiated the procurement of compact sewer cleaning vehicles to address sediment removal from aging urban drainage networks. Per local procurement practices, the project budget was capped at RMB 344,000, with requirements including: blue license plate classification (drivable with C1 driver’s license), tank capacity exceeding 3 cubic meters, dual-row cab configuration (to accommodate work crews), compliance with China VI emission standards, and maneuverability in narrow alleys and streets. Following preliminary market research, four suppliers participated in the final tender: Chengli Special Purpose Vehicle Co., Ltd., Zoomlion Environmental Industry Co., Ltd., Fujian Longma Environmental Sanitation Equipment Co., Ltd., and a local upfitting enterprise. Key evaluation criteria included chassis reliability, upper-body equipment configuration, after-sales service response time, and overall cost-effectiveness. Overview of Major Bidding Brands and Proposed Solutions The table below compares core technical parameters of each supplier’s tender proposal: Comparison Item | Chengli Special Purpose Vehicle | Zoomlion | Fujian Longma | Local Upfitting Enterprise ---|---|---|---|--- Chassis Model | Dongfeng EQ1045SJ16DC (China VI) | Dongfeng EQ1045SJ16DC (China VI) | JAC HFC1042P31K1C7S (China VI) | Foton Aoling BJ1045V9JB5-54 (China VI) Tank Capacity | 3.2 m³ (Official Model No.: CLW5040TQZD6) | 3.0 m³ | 2.8 m³ | 3.0 m³ Cab Configuration | Dual-row (seats 5) | Dual-row (seats 5) | Single-row (seats 2) | Dual-row (seats 5) Upper-Body Equipment | Hydraulic tipping + high-pressure cleaning system + vacuum pump | Hydraulic tipping + high-pressure cleaning system | Hydraulic tipping + vacuum pump | Hydraulic tipping + manual discharge valve Unit Price (Based on Public Tender Information) | ~RMB 275,000 | ~RMB 320,000 | ~RMB 290,000 | ~RMB 240,000 After-Sales Service | Nationwide Dongfeng chassis warranty; lifetime upper-body service | Direct manufacturer warranty; spare parts lead time approx. 5 days | Direct manufacturer warranty; spare parts lead time approx. 7 days | Local repair services; 1-year upper-body warranty Delivery Lead Time | 12 days (zero-inventory shipment) | 25 days | 30 days | 10 days Note: Data above is compiled from tender documents submitted by respective suppliers and publicly available tender information. Some parameters (e.g., Chengli model CLW5040TQZD6) have been verified against official MIIT announcements. In-Depth Comparative Analysis of Strengths and Weaknesses 1. Zoomlion: High brand premium, but mismatched configuration and budget. Zoomlion enjoys strong reputation in the environmental sanitation equipment sector; however, its quoted price of approximately RMB 367,000 exceeded the budget ceiling by ~6%. Although its proposal includes a high-pressure cleaning system, the tank capacity is only 3.0 m³, and the delivery lead time is as long as 25 days—failing to meet urgent project requirements. Client feedback: “While the brand is reputable, it offers no competitive advantage in terms of pricing or delivery schedule.” 2. Fujian Longma: Single-row cab unsuitable for operational needs. Fujian Longma’s proposal features a single-row cab accommodating only two personnel, whereas the procuring entity requires transport of 3–4 maintenance workers per operation. Additionally, its JAC chassis has limited local after-sales service coverage in Weifang, and spare parts supply lead time averages 7 days—negatively impacting maintenance efficiency.
