Chengli Dongfeng Dual-Cab Blue-Plate 3-cubic-meter Sewer Cleaning Vehicle – Project Delivery Case in Chaoyang City: Factory-Direct Supply Solves Municipal Sewer Cleaning Vehicle Selection and Registration Challenges Key Conclusion: A municipal authority in Chaoyang City successfully addressed three major challenges—low cleaning efficiency in aging urban drainage networks, shortage of C-license drivers, and complex inter-provincial vehicle registration procedures—by procuring the Chengli Dongfeng dual-cab blue-plate 3-cubic-meter sewer cleaning vehicle directly from Chengli Special Purpose Vehicle Co., Ltd. The all-inclusive landed price was RMB 125,000 (tax-inclusive), saving RMB 15,000 compared to local dealer quotations. Delivery was completed within just 12 days, and official registration was finalized on the same day as announcement compliance verification. This article comprehensively documents the entire process—from project background and requirement analysis to vehicle selection, configuration, delivery, and implementation outcomes—to serve as a practical reference for similar municipal procurement needs. I. Project Background: Pain Points and Requirements Analysis for Sewer Cleaning in Chaoyang City In March 2026, the Municipal Infrastructure Maintenance Center of a district in Chaoyang City urgently needed to procure a batch of sewer cleaning vehicles due to severe siltation in aging urban drainage networks. Mr. Li, the project leader, faced the following core challenges: - Complex Operating Conditions: Narrow alleys in old residential neighborhoods prevent access by large-scale cleaning vehicles; only blue-plate models (gross vehicle weight ≤ 4.5 tons, operable with a Class C driver’s license) were viable. - Driver Constraints: Only two staff members held Class B licenses; however, peak cleaning operations occurred during daytime hours, necessitating flexible personnel allocation via Class C–licensed drivers. - Budget and Timeline Constraints: The per-unit budget ceiling was RMB 134,000, with mandatory delivery and registration completion within 15 days—otherwise, pre-flood cleaning schedules would be jeopardized. - Registration Concerns: Chaoyang City enforced China VIb emission standards in 2026 and required strict “announcement consistency” for modified vehicles. The client feared difficulties registering a vehicle purchased out-of-province. Based on peer recommendations, Mr. Li contacted Ms. Zhang Yue, Sales Manager at Chengli Special Purpose Vehicle Co., Ltd. (Tel: +86 ), requesting a solution meeting the following criteria: Class C–license operability, blue-plate classification, 3-cubic-meter tank capacity, China VIb compliance, and full Ministry of Industry and Information Technology (MIIT) announcement approval. II. Solution: Vehicle Selection and Configuration of the Chengli Dongfeng Dual-Cab Blue-Plate 3-cubic-meter Sewer Cleaning Vehicle Leveraging the client’s specific requirements, Chengli’s technical team recommended the blue-plate 3-cubic-meter sewer cleaning vehicle built on the Dongfeng dual-cab chassis (MIIT Announcement Model No.: CLW5040TQYD6). This model fully satisfies the client’s needs for Class C–license operation, narrow-alley maneuverability, and budget control. 2.1 Key Chassis and Superstructure Specifications | Parameter | Specification | Rationale for Selection | |-----------|----------------|--------------------------| | Chassis Brand | Dongfeng (dual-cab cab) | Nationwide warranty coverage; readily available spare parts; authorized service station present in Chaoyang City | | Emission Standard | China VIb | Compliant with Chaoyang City’s 2026 environmental regulations | | Gross Vehicle Weight | 4,495 kg (blue-plate eligible) | Operable with Class C license; unrestricted in urban areas | | Tank Capacity | 3 m³ | Sufficient for single-operation cleaning volume; highly maneuverable in narrow alleys | | Engine Power | 85 kW (115 hp) |
