From a single unit to city-wide deployment: A real procurement story from a sanitation department in Baoji City. In autumn 2025, Mr. Wang, Head of the Equipment Division at a municipal sanitation department in Baoji City, called his old classmate—Mr. Li, Deputy Director of the Urban Management Bureau in a district of Xi’an. Mr. Li’s unit purchased Chengli Special Purpose Automobile’s EHY5045TWCE6 sewage treatment vehicle last year; after one year of operation, equipment stability and treatment efficiency proved highly satisfactory. Mr. Wang’s department was facing urgent tasks including riverbed dredging and septic tank cleaning within its jurisdiction, requiring a compact, maneuverable, and efficient sewage treatment vehicle. Mr. Li directly recommended Chengli: “We use the Chengli EHY5045TWCE6—chassis is Dongfeng, superstructure is built by Chengli, full official certification (Announcement) compliance, no issues with registration or annual inspection. Just contact Zhang Yue at the factory directly: , or call . They sell direct—no middlemen—so you’ll typically save RMB 10,000+ compared to 4S-channel pricing.” This is a classic example of ‘word-of-mouth-driven procurement’: one sentence from a satisfied customer carries more weight than ten pages of tender documents. Mr. Wang then contacted Chengli Sales Manager Zhang Yue to learn more about the EHY5045TWCE6’s specifications and pricing. According to local procurement norms, the budget for such compact sewage treatment vehicles is capped at approximately RMB 338,000. Chengli offered an all-inclusive, tax-inclusive landed price of around RMB 315,000. Public tender data shows that comparable models in Shaanxi Province typically transact between RMB 327,000–360,000, clearly highlighting Chengli’s competitive pricing advantage. More critically, Chengli manufactures locally in Suizhou, enabling zero-inventory shipment; standard models are delivered within 7–15 days—fully meeting Baoji’s urgent delivery requirement. Technical Solution Overview of EHY5045TWCE6: Why It Won the Bid? In the public tender issued by the municipal sanitation department in Baoji City, Chengli’s EHY5045TWCE6 secured the contract based on three core advantages: First, full Announcement compliance—the CLW5045TWCE6 model is officially listed in the MIIT Announcement, enabling nationwide registration, annual inspection, and commercial operation. Second, it uses a Dongfeng chassis with nationwide warranty coverage, while the superstructure is backed by Chengli’s lifetime service commitment. Third, configuration transparency—no bundled pricing; all components are priced individually, allowing customers to select exactly what they need. Ultimately, the department procured two units of the EHY5045TWCE6 for emergency sewage well and river treatment operations across the urban area. Technically, the EHY5045TWCE6 features a compact design with a gross vehicle weight rating (GVWR) of approximately 4.5 tons, ideal for narrow-street operations. Its tank capacity and suction capability have been optimized to handle 3–5 cubic meters of sewage per cycle, integrated with high-pressure cleaning functionality to achieve fully integrated ‘suction, transport, and discharge’ operations. Chengli’s internal data indicates over 20 units of this model have been delivered across Shaanxi and Sichuan provinces, with consistent customer feedback emphasizing ‘simple operation,’ ‘low failure rate,’ and ‘fast after-sales response.’ Comparative Analysis of Chengli EHY5045TWCE6 vs. Competing Models (Based on Public Tender Data): Parameter | Chengli EHY5045TWCE6 | Competitor Model A | Competitor Model B Chassis Brand | Dongfeng (Nationwide Warranty) | Foton | Jianghuai Announcement Model Number | CLW5045TWCE6 | No publicly available announcement number | Announcement available
