Project Background: Municipal Sludge Removal Equipment Upgrade in Liaoyang City, Liaoning Province In April 2026, a municipal engineering company in Liaoyang City, Liaoning Province, urgently needed to procure a batch of blue-plate sludge removal vehicles for urban pipeline maintenance, due to frequent breakdowns and non-compliant emissions from aging units. The customer contacted Sales Manager Zhang Yue (Tel: +86 ) via Chengli Special Vehicle’s official website (www.clspecial.com), highlighting three core challenges: - Budget Constraint: Strict per-unit budget cap of RMB 132,000, inclusive of all taxes and delivery-ready “landed” cost. - Driving License Restriction: Operators hold only C1 licenses; thus, vehicles must be blue-plate (gross vehicle weight ≤ 4.5 tons) and fully compliant with Liaoyang’s local registration requirements. - Delivery Timeline: To meet pre-flood season pipeline cleaning deadlines, the customer required vehicle dispatch within 20 days from contract signing. After multiple rounds of comparison, the customer selected Chengli Special Automobile Co., Ltd.’s Dongfeng double-cab sludge removal vehicle (blue-plate, 3 m³ capacity). This model features a Dongfeng chassis, full regulatory approval (MIIT Announcement No.: CLW5040TQYD6), meets China VI emission standards, and is legally operable with a C1 license—fully satisfying Liaoyang’s environmental and registration policies. Solution: Configuration & Quotation of Chengli Dongfeng Double-Cab Sludge Removal Vehicle Tailored to the customer’s requirements, Chengli proposed the following customized solution: | Item | Specific Parameters / Details | |------|-------------------------------| | Vehicle Model | CLW5040TQYD6 (Dongfeng Double-Cab Sludge Removal Vehicle) | | Chassis Brand | Dongfeng (authorized first-tier distributor; factory chassis covered by nationwide warranty) | | Tank Capacity | 3 m³ (actual loading capacity: approx. 2.8–3.2 m³) | | Emission Standard | China VI (fully compliant with Liaoyang’s 2026 environmental regulations) | | Authorized Driving License | C1 (blue-plate; gross vehicle weight ≤ 4.5 tons) | | Tax-Inclusive Landed Price | RMB 108,000 (includes freight, registration assistance, and first-year compulsory traffic insurance) | | Delivery Cycle | 18 days from contract signing to dispatch (covers production, inspection, and logistics) | | After-Sales Service | Nationwide Dongfeng chassis warranty; lifetime upfit service by Chengli; spare parts shipped within 24 hours | Compared to competing brands offering identical specifications (quoted at RMB 138,000–143,000), Chengli’s direct-manufacturer sales model saved the customer approximately RMB 17,000—with full configuration transparency and zero hidden fees. Implementation Results: End-to-End Delivery Timeline - April 12, 2026: Customer submitted inquiry via official website; Zhang Yue responded the same day with technical documentation and quotation. - April 15, 2026: Customer visited Chengli Industrial Park in Suizhou, Hubei Province, for on-site vehicle inspection and final configuration confirmation. - April 18, 2026: Contract signed; 50% advance payment received; Chengli initiated production. - May 2, 2026: Vehicle completed assembly; passed chassis inspection, upfit commissioning, and MIIT announcement verification. - May 6, 2026: Dispatched via dedicated transport; scheduled arrival in Liaoyang on May 10. - May 10, 2026: Vehicle delivered on schedule to the designated location in Liaoyang; customer accepted after successful inspection.
