Project Background: Pain Points in Sewer Cleaning and Vehicle Selection Requirements in Fushun City, Liaoning Province In May 2026, the Fushun Municipal Administration Bureau launched a public tender for lightweight sewer cleaning vehicles to address chronic sediment removal challenges in the city’s aging underground pipeline network. The project’s core requirements were clearly defined: vehicles must be operable with a Class C driver’s license (blue-plate registration), feature a 3-cubic-meter effective tank capacity, be built on Dongfeng chassis (with dense local service station coverage), and be eligible for standard nationwide registration. Given Fushun’s harsh winter climate—where temperatures regularly drop below –25°C—the hydraulic system and sealing performance had to meet exceptionally high standards. Additionally, the budget was strictly capped at RMB 120,000 per vehicle (tax-inclusive, delivered price). After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. secured the bid for the first batch of five Dongfeng double-cab blue-plate 3-cubic-meter sewer cleaning vehicles at RMB 112,000 per unit. Chengli’s winning proposal was underpinned by its complete MIIT vehicle type approvals, status as a Tier-1 authorized Dongfeng chassis distributor, and rapid delivery capability from its Suizhou factory—operating on a zero-inventory model. This project marks another benchmark case for Chengli in municipal sewer cleaning across Northeast China, powerfully validating its core competitive advantages: “full MIIT approvals + OEM chassis + lifetime upfit service.” Solution: In-Depth Configuration Analysis of the Dongfeng Double-Cab Blue-Plate 3-m³ Sewer Cleaning Vehicle To meet Fushun’s specific requirements, Chengli supplied the CLW5040TQYD6 model—fully compliant with all MIIT announcement parameters—with the following key configurations: | Configuration Item | Specific Parameters / Description | Key Advantages | |----------------------------|---------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------| | Chassis Brand | Dongfeng double-cab (China VI emission standard) | Nationwide warranty; local service stations in Fushun ensure prompt maintenance | | Engine | Quanchai Q23-95E60 (95 hp) | High torque output, low fuel consumption—ideal for frequent urban start-stop cycles | | Cab | Double-cab (rated capacity: 5 persons) | Enables transport of full work crews, eliminating repeated personnel shuttles | | Gross Vehicle Weight / Curb Weight | 4,495 kg / 2,860 kg | Compliant with blue-plate Class C license requirements—no need for additional driver certification | | Tank Capacity | 3 m³ (effective volume) | Optimally sized for routine cleaning tasks—avoids overloading or underutilization | | Cleaning System | Hydraulic-driven auger + high-vacuum suction | Dual functionality (suction & discharge); handles mixed media including sludge, sand, gravel, and wastewater | | Sealing Performance | Dual-layer tank sealing + low-temperature hydraulic oil | Reliable operation down to –25°C; zero leakage under extreme cold conditions | | Delivery Lead Time | 10 working days after contract signing
