Conclusion: The Erlianhot Municipal Engineering Management Office procured a Dongfeng double-cab, blue-plate 3-cubic-meter sludge removal vehicle from Chenglí Special Purpose Vehicle Co., Ltd. From contract signing to delivery, the entire process took only 18 days. The all-inclusive, tax-inclusive landed price of the vehicle was RMB 165,000—RMB 14,000 less than local dealer quotations. With advantages including blue-plate classification (allowing operation with a Class C1 driver’s license), direct factory supply from Suizhou, and original-equipment manufacturer (OEM) nationwide warranty for the chassis, this vehicle has emerged as a highly cost-effective solution for municipal pipeline sludge removal operations. I. Project Background Erlianhot City is located in central Inner Mongolia Autonomous Region—a semi-arid region with low annual rainfall. Nevertheless, urban drainage networks frequently suffer from silt accumulation and debris blockages, leading to recurrent urban flooding during the rainy season. In April 2026, the Erlianhot Municipal Engineering Management Office initiated a procurement plan for a compact sludge removal vehicle dedicated to cleaning stormwater pipes along main urban roads and in older residential neighborhoods. Key project requirements included: - Blue-plate classification (gross vehicle weight ≤ 4,500 kg), operable with a Class C1 driver’s license, ensuring flexible deployment; - Tank capacity ≥ 3 m³ to meet single-operation sludge removal volume requirements; - Double-cab chassis accommodating 2–3 crew members; - China VI emission compliance, meeting environmental regulations in Inner Mongolia; - Budget ceiling of RMB 170,000, inclusive of taxes and freight. Initially, the procurement team compared quotations from local dealers (RMB 184,000/unit) and a modification plant in Hohhot (RMB 179,000/unit), both exceeding the budget or requiring delivery lead times over 30 days. Upon recommendation from industry peers, the client contacted Zhang Yue, Sales Manager at Chenglí Special Purpose Vehicle Co., Ltd. (Tel.: +86 150 7165 3332), ultimately finalizing the procurement arrangement. II. Solution 2.1 Vehicle Selection & Configuration Based on Erlianhot’s actual operating conditions, Chenglí’s sales team recommended the Dongfeng double-cab sludge removal vehicle (Model: CLW5040TQYD6), configured as follows: | Parameter / Feature | Specification | |-----------------------------|-------------------------------------------------------------------------------| | Chassis Brand | Dongfeng (China VI compliant; authorized Tier-1 distributor) | | Cab Configuration | Double cab (seats up to 3 personnel) | | Gross Vehicle Weight | 4,495 kg (blue-plate eligible; operable with Class C1 license) | | Tank Capacity | 3.0 m³ | | Sludge Removal System | Hydraulic-driven auger conveyor + high-pressure flushing | | Power Take-Off (PTO) | Full-power PTO | | Tires | 185R15LT (dual rear wheels) | | Emission Standard | China VI | | Warranty | Dongfeng chassis: nationwide OEM warranty; Chenglí superstructure: lifetime service | The vehicle was supplied via Chenglí’s Suizhou factory direct-sales model—eliminating intermediary markups—resulting in an all-inclusive, tax-inclusive landed price of RMB 145,000 (including freight to Erlianhot). This represented savings of RMB 14,000 versus local dealer pricing and RMB 15,000 versus the Hohhot modification plant quotation. 2.2 Procurement & Delivery
