Project Background: Municipal Sludge Removal Pain Points and Urgent Needs in Inner Mongolia In May 2026, a municipal authority in the Inner Mongolia Autonomous Region urgently needed to procure high-efficiency sludge removal equipment due to severe blockages in urban drainage networks—posing a critical threat to flood control safety during the rainy season. After comprehensive evaluation, the authority selected CLW Special Purpose Vehicle Co., Ltd.’s Dongfeng double-cab sludge removal truck (blue license plate, 3 m³ capacity), with a total procurement value of RMB 1.08 million (tax-inclusive landed price) for 10 units. The project required delivery of the first batch by the end of June to ensure readiness ahead of the main flood season. Inner Mongolia features an arid climate, yet localized heavy rainfall frequently triggers urban flooding. Traditional manual sludge removal is inefficient and hazardous. Previously, the authority had attempted renting sludge removal equipment, but encountered issues including insufficient chassis durability, frequent clogging of upper assemblies, and slow after-sales response. This procurement aims to achieve mechanized operations using CLW’s blue-plate sludge removal trucks—enhancing efficiency and significantly reducing labor intensity for workers. As a manufacturer holding official special-purpose vehicle production qualifications from China’s Ministry of Industry and Information Technology (MIIT)—with complete MIIT announcements enabling nationwide registration—CLW offers the Dongfeng double-cab sludge removal truck built on a Dongfeng chassis, fully compliant with China VI emission standards. Its blue license plate classification allows operation with a Class C driver’s license, making it ideal for narrow urban streets. Upon project initiation, CLW’s team responded swiftly, providing full-cycle support—from model selection and production to delivery. Solution: CLW Dongfeng Double-Cab Sludge Removal Truck (Blue Plate, 3 m³) – Configuration Details To meet the specific requirements of the Inner Mongolia project, CLW supplied the Dongfeng double-cab sludge removal truck (model CLW5040TQYD6), with the following specifications: | Parameter | Specification/Description | |-----------|----------------------------| | Chassis Model | Dongfeng EQ1045SJ3CDF | | Emission Standard | China VI | | Cab Configuration | Double-cab, seating up to 5 persons | | Tank Capacity | 3 m³ (combined sewage + clean water tanks) | | Gross Vehicle Weight (GVW) | 4,495 kg | | Upper Assembly | High-pressure cleaning pump (≥16 MPa), vacuum suction pump (≥180 m³/h), hydraulic hose reel (20 m high-pressure hose), onboard tools | | Special Functions | Integrated cleaning, suction, and sludge removal; capable of crushing obstructions | | MIIT Announcement Model | CLW5040TQYD6 (full MIIT announcement, eligible for nationwide registration) | | Delivery Lead Time | 7–15 days for standard models (15 days for this project’s first batch) | | After-Sales Policy | Dongfeng chassis covered under nationwide warranty; CLW upper assembly supported by lifetime service; spare parts shipped within 24 hours | Key advantages of this model include: - Operable with a Class C driver’s license (no Class B required), lowering driver qualification barriers; - Double-cab design accommodates full operational crews; - 3 m³ tank capacity optimally suited for short-distance sludge transport in urban environments; - Integrated high-pressure cleaning and vacuum suction enables end-to-end pipeline unclogging, sewage suction, and sludge removal in a single vehicle; - CLW’s upper assembly uses wear-resistant, corrosion-resistant materials engineered for Inner Mongolia’s extreme temperature fluctuations and high sand/dust conditions. Implementation Results: First Batch of 5 Units Delivered—Outstanding Operational Performance As of June 14, 2026, the first batch of five Dongfeng double-cab sludge removal tr
