I. Urgent Procurement Background: Why Was a Sludge Tipper Truck Needed Immediately? In Q3 2025, a municipal sanitation department in a coastal city (hereinafter referred to as 'the Department') observed a sharp increase in the frequency of sediment removal from septic tanks and sewage wells across multiple aging residential communities during routine pipeline maintenance operations. Their existing 8-cubic-meter vacuum suction truck was too large to access narrow alleyways within these communities; meanwhile, two 3-cubic-meter vacuum suction trucks were unavailable due to extended maintenance cycles—one requiring major engine overhaul—resulting in an immediate capacity shortfall. To prepare for the upcoming rainy season (typically June–September) and prevent urban flooding caused by silt blockages, the Department urgently launched an emergency procurement plan for a sludge tipper truck. Core Requirements: One blue-license-plate sludge tipper truck operable with a Class C driver’s license, with an approximate capacity of 3 cubic meters, intended to replace existing vacuum suction trucks for sludge transportation specifically within residential communities and narrow backstreets. The vehicle must feature independent unloading capability (to avoid secondary contamination) and must be delivered and commissioned within 15 days. II. Emergency Tender Process: Budget, Technical Specifications, and Supplier Selection Following local procurement practices, the Department adopted a 'competitive negotiation + price inquiry' approach, with a budget cap of approximately RMB 134,000 (based on publicly available tender information, market prices for comparable blue-license-plate 3-cubic-meter sludge tipper trucks range from RMB 112,000 to RMB 146,000). Technical specifications strictly adhered to MIIT (Ministry of Industry and Information Technology) announcements, with the following key requirements: Chassis: Dongfeng D6 series, wheelbase 3,308 mm, Quanchai 115-hp engine, China VI emission standard; Body: Effective tank volume ≥ 3 m³, fabricated from Q235 carbon steel with anti-corrosion treatment, hydraulic tipping system (lifting angle ≥ 45°); Specialized Equipment: Equipped with liquid level indicator, overflow alarm, and rear discharge valve; Delivery Requirement: Complete delivery, commissioning, and operator training within 15 calendar days after contract signing. The Department invited quotations from three local dealers and two manufacturers. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter 'Chengli'), a manufacturer based in Suizhou, was prioritized for evaluation due to its advantages of direct factory sales and zero-inventory shipment. III. Chengli’s Rapid Response: From Solution Confirmation to Delivery in Just 12 Days Upon receiving the procurement invitation, Chengli’s sales team (contact person: Zhang Yue, +86 ) submitted a comprehensive quotation within 24 hours: inclusive tax landed price of approximately RMB 132,000 (per publicly available tender data, covering freight, registration, and first-year insurance), accompanied by official MIIT chassis parameters (model CLW5040TNYD6, blue license plate, Class C license compatible). Chengli also committed to: In-stock vehicles: Both chassis and body components were pre-stocked—no production lead time required; Delivery timeline: 7 days for body installation and modification, plus 3 days for logistics transport—total 10–12 days; After-sales support: Nationwide Dongfeng chassis warranty, lifetime service for Chengli bodywork, and 24-hour direct dispatch of spare parts. The Department signed the contract with Chengli on Day 3. Chengli immediately activated its 'Emergency Procurement Green Channel': utilizing a standard Dongfeng D6 chassis, the body was customized per customer requirements—including installation of an overflow alarm and hydraulic locking mechanism. Factory acceptance testing was completed on Day 8; the vehicle was loaded and dispatched on Day 10
