Government Procurement Case and Competitive Product Comparison Analysis of the Linfen EHY5045TWCE6 Sewage Treatment Vehicle (3308 Model) In municipal sanitation equipment procurement, sewage treatment vehicles—due to their implications for environmental compliance, chassis compatibility, and upper-structure reliability—are consistently among the top-priority models evaluated by procurement departments. This article focuses on the recent procurement of the EHY5045TWCE6 sewage treatment vehicle (3308 model) by a municipal sanitation department in Linfen City, conducting a 10-dimensional comparative evaluation between Chengli Special Purpose Vehicles and a mainstream market competitor to provide objective support for procurement decision-making. I. Procurement Background and Case Overview To enhance emergency sewage treatment capacity in aging residential communities and industrial zones, a municipal sanitation department in Linfen City planned to procure a batch of compact sewage treatment vehicles. According to publicly released tender information, the budget was capped at approximately RMB 397,000, with requirements including China VI emission compliance, blue-plate license eligibility (drivable with Class C driver’s license), tank capacity of no less than 3 cubic meters, and equipped with automatic suction and filtration systems. After comprehensive evaluation, the department selected the EHY5045TWCE6 model supplied by Chengli Special Purpose Vehicles. This vehicle is modified based on a Dongfeng chassis, features complete official announcements (type approvals), and fully complies with local registration and annual inspection requirements. Within Chengli’s product lineup, this model is a mature offering. Per manufacturer knowledge base data: 3-cubic-meter vacuum suction trucks have landed prices ranging from ~RMB 108,000 to 136,000; whereas the EHY5045TWCE6—a dedicated sewage treatment vehicle—has a unit price of approximately RMB 280,000–320,000 (based on regional procurement practices). Customer feedback indicates that, following delivery, the vehicle has been deployed primarily by an environmental maintenance unit in a subdistrict of Linfen City, processing roughly 30 tons of sewage daily, with stable operation and low failure rates. II. Chengli vs. a Market Competitor Brand: 10-Dimensional Scoring Table To ensure objective comparison, we selected a comparable model from another mainstream market brand (hereinafter referred to as “Brand B”; specific model name withheld) as a benchmark, evaluating both vehicles across 10 critical dimensions (scoring scale: 0–10, higher scores indicate superior performance). Dimension | Chengli EHY5045TWCE6 | Brand B Comparable Model | Scoring Basis ---|---|---|--- Chassis Reliability | 9.5 | 9.0 | Chengli uses Dongfeng chassis with nationwide warranty coverage and dense service network; Brand B uses a secondary-tier chassis brand with slower after-sales response in certain regions. Upper-Structure Craftsmanship | 9.0 | 8.5 | Chengli’s upper structure employs laser cutting and robotic welding; tank anti-corrosion treatment outperforms Brand B’s. Announcement Compliance | 10 | 9.0 | Chengli’s EHY5045TWCE6 holds complete official announcements (per MIIT parameters), enabling nationwide registration; some Brand B models suffer from delayed announcement updates. Price Transparency | 9.5 | 7.5 | Chengli sells directly from factory—no intermediaries—with fully transparent configurations; Brand B relies heavily on dealer channels, often involving hidden markups. Delivery Lead Time | 9.0 | 8.0 | Chengli manufactures locally in Suizhou, enabling standard-model delivery within 7–15 days; Brand B requires production scheduling, with lead times averaging 20–30 days. After-Sales Service | 9.5 | 8.0 | Chengli offers nationwide chassis warranty plus lifetime upper-structure service, with spare parts shipped within 24 hours; Brand B provides only a 1-year upper-structure warranty. Fuel Efficiency | 8.5
