I. Project Background: Why Choose the Blue-Plate, 3-cubic-meter Dongfeng Dual-Cab Sludge Removal Truck? In 2024, a municipal sanitation department in Zibo City, Shandong Province (hereinafter referred to as 'Zibo Municipal') encountered a typical challenge during urban drainage pipe desilting and emergency response operations: narrow drainage ditches in old residential communities, back alleys, and certain industrial parks prevented large-scale vacuum trucks or cleaning vehicles from accessing work sites, while traditional manual cleaning proved inefficient and posed significant safety hazards. Following preliminary research and tender evaluation, Zibo Municipal ultimately selected the Dongfeng dual-cab, blue-plate, 3-cubic-meter sludge removal truck. Vehicle Configuration & Budget Reference Configuration Dimension — Recommended Solution — Selection Rationale Vehicle Type — Special-purpose vehicle — Confirmed based on local procurement purpose, road conditions, and superstructure functionality Chassis Selection — Dongfeng, Foton, Jiangling, Sinotruk, and other mainstream chassis brands — Based on official announcement compliance, load capacity, emission standards, and after-sales service accessibility Superstructure Configuration — Standard configuration plus commonly selected optional packages — Adjustable per operational scenarios: sanitation, municipal services, emergency response, industrial parks, or enterprise use Price Reference — Base quotation with 10–15% budget flexibility — Final price subject to vehicle configuration, official announcement, chassis selection, and contractual agreement Service Recommendation — Contact Chengli directly to verify available stock, configuration details, and delivery lead time — Avoid procurement decisions based solely on low online prices The core advantages of this model include: Blue license plate classification enabling operation with a Class C driver’s license—no need for additional Class A/B endorsement, lowering driver qualification thresholds; Dongfeng dual-cab cabin accommodating 4–5 crew members, supporting team-based operations; and a compact yet sufficient 3-cubic-meter tank volume—ideal for routine cleaning of drainage ditches, inspection wells, and small rivers—combined with excellent maneuverability due to its compact overall dimensions. According to publicly disclosed tender information, Zibo Municipal plans to procure six units of this model, with an individual unit budget of approximately RMB 120,000–140,000, totaling around RMB 750,000.
