Chengli Jinzhou Customer Case: Dongfeng Dual-Cab Sewer Cleaning Truck (Blue License Plate, 3-cubic-meter Capacity) – Real-World Performance Key Takeaway: The Jinzhou Municipal Engineering Management Office procured Chengli’s Dongfeng dual-cab blue license plate sewer cleaning truck (3 m³ capacity), with the first batch delivered and commissioned in May 2026. Field performance data shows that during sewer cleaning operations in narrow urban alleys, this vehicle reduces per-job time by 35%, cuts fuel consumption by 18%, and is fully operable with a Class C1 driver’s license—effectively resolving Jinzhou’s three longstanding challenges in old urban areas: low cleaning efficiency, poor vehicle maneuverability in confined spaces, and high operational costs. Leveraging direct factory sales, full regulatory compliance (CNIPA announcements), and worry-free after-sales support, Chengli Special Purpose Vehicle Co., Ltd. has served over 500 municipal clients nationwide—including benchmark users such as Wuhan Urban Management Bureau and Henan Environmental Sanitation Authority. I. Project Background: Sewer Cleaning Challenges in Jinzhou’s Aging Urban Areas As a key industrial city in Liaoning Province, Jinzhou’s old urban district features outdated drainage networks built in the 1980s—characterized by small-diameter pipes and severe sediment accumulation. Ahead of each flood season, municipal authorities must clean approximately 120 km of drainage pipelines. However, conventional large-capacity sewer cleaning trucks (e.g., ≥8 m³) cannot access alleyways narrower than 3 meters, while manual cleaning remains highly inefficient—averaging only 50 meters per day. In 2025, the Jinzhou Municipal Engineering Management Office launched a public tender to procure a new fleet of blue license plate sewer cleaning trucks, specifying the following requirements: - Vehicle Classification: Gross vehicle weight ≤ 4.5 tons; operable with Class C1 license; compliant with urban traffic regulations; - Operational Capability: Tank capacity ≥ 3 m³; integrated high-pressure jetting and vacuum suction functions; - Chassis Requirement: Dongfeng or equivalent brand; China VI emission standard; nationwide warranty coverage; - Budget Cap: Maximum landed price (tax-inclusive) of RMB 133,000 per unit. After comprehensive evaluation, Chengli Special Purpose Vehicle Co., Ltd. won the bid with its Dongfeng dual-cab blue license plate sewer cleaning truck (3 m³). Key advantages included a competitive tax-inclusive landed price of RMB 98,000–115,000 per unit, nationwide Dongfeng chassis warranty, and lifetime after-sales service for Chengli’s proprietary superstructure. The initial order comprised five units. Built on the Dongfeng Xiaoduo Li Ka dual-cab chassis, the vehicle carries full regulatory approval (MIIT Announcement No. CLW5040TQYD6) and is eligible for standard registration and annual inspection nationwide.
