Case Study and Winning Bid Solution Analysis: Xuchang Municipal Government Procurement of Dongfeng Dual-Cab Sludge Suction Trucks (Blue License Plate, 3 m³ Capacity) In urban drainage network maintenance, sludge suction trucks are indispensable specialized vehicles. Recently, a municipal sanitation department in Xuchang planned to procure a batch of Dongfeng dual-cab blue license plate 3 m³ sludge suction trucks to meet routine cleaning requirements for urban stormwater pipes, sewage wells, and culverts. This article analyzes Chengli Special Purpose Vehicle’s supply solution, vehicle configuration, and one-stop procurement advantages based on the actual government procurement process. Project Background and Procurement Requirements The municipal sanitation department is responsible for maintaining approximately 30 square kilometers of drainage infrastructure across Xuchang city. Its existing sludge removal equipment is outdated and inefficient, necessitating urgent replenishment with new blue license plate sludge suction trucks. According to publicly released tender information, key procurement requirements include: Dongfeng dual-cab chassis (accommodating 3–5 personnel), blue license plate operable with Class C driver’s license, tank capacity of approximately 3 m³, integrated high-pressure cleaning and vacuum suction functionality, compliance with China VI emission standards, and nationwide registration and annual inspection eligibility. The budget is controlled at approximately RMB 120,000–150,000 per unit; following local procurement practice, the initial delivery plan covers two units. Analysis of Chengli’s Winning Bid Solution As a leading domestic special-purpose vehicle manufacturer, Chengli Special Purpose Vehicle Co., Ltd. secured the contract by leveraging its comprehensive official vehicle announcements, factory-direct sales model, and robust after-sales support. Two Dongfeng dual-cab blue license plate 3 m³ sludge suction trucks (reference model: CLW5070GSSD6 chassis) were successfully delivered to the client. Below is a detailed breakdown of this solution: 1. Vehicle Suitability Chassis Selection: Dongfeng dual-cab chassis equipped with Quanchai or Yuchai engine—delivering ample power and accommodating three operational personnel for mobile inspection tasks. Tank Specifications: Effective tank capacity approx. 3 m³; constructed from premium carbon steel with anti-corrosion treatment for extended service life. Operational Functions: Integrated high-pressure cleaning pump (pressure ≥16 MPa) and vacuum suction pump (suction lift ≥6 m), enabling combined cleaning and suction operations for enhanced efficiency. Regulatory Compliance: Fully compliant with China VI emission standards; complete official vehicle announcement documentation; blue license plate operable with Class C driver’s license; hassle-free registration and annual inspection nationwide. 2. Pricing and Budget Control Based on Chengli’s tax-inclusive landed price (2026 reference), the market price for blue license plate 3 m³ vacuum suction trucks/sludge suction trucks ranges from RMB 95,000 to 120,000 per unit (per internal knowledge base data). Considering this project’s specific configuration (dual-cab chassis + high-pressure cleaning system), the final delivery price was approximately RMB 110,000–130,000 per unit—significantly lower than comparable 4S dealership quotations, achieving direct savings of RMB 8,000–15,000 per unit, fully meeting the budgetary constraints. 3. Delivery Timeline Chengli manufactures locally in Suizhou, enabling standard-model deliveries within 7–15 days. For this order, both units were produced, finalized, and dispatched within just 12 days from order confirmation—ensuring timely deployment by the municipal authority.
