Government Procurement Case and Bid-Winning Solution Interpretation for the Huanggang Dongfeng Double-Cab Sludge Suction Truck (Blue License Plate, 3 m³) In the municipal sanitation sector, sludge suction trucks serve as essential equipment for maintaining drainage networks; procurement decisions directly influence operational efficiency and lifecycle operating costs. Recently, the Urban Management Bureau of a district in Huanggang initiated a procurement project for Dongfeng double-cab sludge suction trucks (blue license plate, 3 m³) to meet sludge removal requirements in aging pipeline networks across its jurisdiction. This article takes this case as a focal point and, leveraging Chengli Special Purpose Vehicle’s proven delivery experience in comparable projects (e.g., 10 units of 5 m³ water sprinkler trucks supplied to Henan Sanitation Department; 4 units of high-pressure cleaning & vacuum suction trucks delivered to Sichuan Municipal Authorities), specifically analyzes how engine power selection (85 kW / 100 kW / 120 kW) impacts vehicle performance, fuel economy, and suitability for various operational scenarios—offering professional guidance for government procurement decisions. All financial data cited herein is based on publicly released tender documents or prevailing local procurement practices. For precise configuration details and quotations, please contact Chengli’s official hotline at or Sales Manager Zhang Yue at . I. Project Background and Requirements Analysis This procurement initiative was launched by a municipal sanitation authority in Huanggang, with an overall budget capped at approximately RMB 321,000 (per publicly disclosed tender information), targeting the acquisition of two blue-license-plate, 3 m³ Dongfeng double-cab sludge suction trucks. Key requirements include: – Vehicle Type: Blue license plate, drivable with Class C driver’s license; gross vehicle weight ≤ 4.5 tons; cargo body capacity of 3 m³—enabling access to old residential communities and narrow urban streets. – Chassis Specification: Dongfeng double-cab chassis accommodating a three-person work crew; compliant with China VI emission standards to ensure nationwide registration eligibility and annual inspection compliance. – Operational Environment: Primarily flat urban roads in the city center, occasionally featuring mild inclines; must perform reliably during rainy seasons in flooded or low-lying areas. – Budget Constraint: Unit price target ~RMB 140,000, balancing cost-effectiveness with long-term maintenance affordability. According to Chengli’s product database (e.g., announcement parameters for model CLW5070GSSD6), blue-license-plate sludge suction trucks typically utilize Dongfeng light-duty chassis, with optional engine outputs ranging from 85 kW to 120 kW. To align with actual working conditions, procuring entities must carefully balance power performance, fuel economy, and initial acquisition cost. II. Comparative Engine Analysis: Differences Among 85 kW / 100 kW / 120 kW Options The engine serves as the core power source for sludge suction trucks, directly affecting both operational efficiency and ongoing operating expenses. Below is a comparative analysis of the three most common power options, based on Chengli’s official announcement models (e.g., CLW5070GSSD6) and industry-wide public data: Parameter 85 kW Engine (~116 HP) 100 kW Engine (~136 HP) 120 kW Engine (~163 HP) Applicable Scenarios Flat terrain, light-load operations; urban paved roads Standard urban operations on flat terrain; occasional mild gradients Hilly/mountainous regions, heavy-load applications, or high-altitude environments Fuel Consumption (per 100 km, reference value) Approx. 10–12 L Approx. 11–13 L Approx. 13–15 L Estimated Purchase Cost RMB 125,000–135,000 RMB 135,000–145,000 RMB 155,000–165,000 Power Response Smooth operation; slightly lower low-speed torque Balanced performance; suitable for mixed road conditions Highly re
