Case Study and Solution Analysis: Zhongshan Dongfeng Single-Cab Sewer Cleaning Truck (Blue License Plate, 5 m³) for Government Procurement. In municipal drainage system maintenance, sewer cleaning trucks are indispensable equipment. Recently, the Urban Management Bureau of a district in Guangdong Province procured three Dongfeng single-cab sewer cleaning trucks (blue license plate, 5 m³) to address the dredging needs of aging pipelines within its jurisdiction. This article analyzes the government procurement plan and implementation key points through dimensions including consumable parts list, transparency of spare parts pricing, Chengli’s 24-hour direct shipment service, and comparison with authorized 4S dealerships. I. Procurement Background and Vehicle Selection The district’s Urban Management Bureau launched a tender in Q4 2025, with a budget capped at approximately RMB 310,000 (per publicly available tender information), aiming to procure three blue-license-plate sewer cleaning trucks with 5 m³ tank capacity. As operations are concentrated on non-arterial urban roads and narrow alleys, vehicle requirements include high maneuverability, excellent off-road capability, and the ability to perform direct manhole entry operations. The selected model features a Dongfeng single-cab chassis paired with Chengli’s proprietary upper structure, a 5 m³ tank, and integrated high-pressure cleaning pump and suction-sewage system. Why Choose a Blue-License-Plate 5 m³ Truck? According to local procurement practice, blue-license-plate vehicles (gross vehicle weight under 4.5 tons) can be operated by drivers holding a Class C1 driver’s license; meanwhile, a 5 m³ tank capacity balances single-operation efficiency against overloading risks. The CLW5070GSSD6 model supplied by Chengli Special Purpose Vehicle Co., Ltd. — developed on the Dongfeng chassis and fully compliant with MIIT certification parameters — is eligible for nationwide registration and annual inspection. II. Consumable Parts List: Cost Items That Must Be Understood Prior to Procurement As specialized vehicles frequently exposed to mud, sand, and wastewater, sewer cleaning trucks experience relatively high replacement frequency for consumable components. In this procurement plan, the procuring entity specifically required suppliers to provide a consumable parts list and associated pricing. Below are typical consumables and their reference prices (based on Chengli’s after-sales database and publicly available industry data): Consumable Name | Replacement Interval (Reference) | Reference Unit Price (RMB) | Notes ---|---|---|--- High-Pressure Hose (with Reel) | 6–12 months | ~800–1,200 | Varies with usage frequency Suction Rubber Hose | 3–6 months | ~300–500 | Wear-resistant type Sealing Rings (Tank Interface) | 12 months | ~50–100 | Prone to aging High-Pressure Water Pump (Plunger Type) | 18–24 months | ~2,000–3,500 | Price varies between imported and domestic units Power Take-Off (PTO) Gear Oil | 6 months | ~150–200 | Maintenance item Tank Anti-Corrosion Paint | 12 months | ~200–400 | Varies by surface area During tender clarification, Chengli explicitly confirmed that all upper-structure consumables would be supplied at cost price, with spare parts shipped within 24 hours (as guaranteed by Chengli’s after-sales service system). This stands in sharp contrast to some authorized 4S dealerships, where spare parts markups typically range from 30% to 50%. III. Spare Parts Pricing Transparency: Chengli vs. Authorized 4S Dealerships In government procurement, spare parts pricing transparency directly impacts long-term operational and maintenance costs. In this case, the procuring entity required suppliers to submit a 'Spare Parts Pricing Commitment Letter.' Below is a comparative analysis of typical spare parts pricing between Chengli’s factory-direct sales channel and an authorized dealership of a certain brand (data sourced from Chengli’s published quotations and industry surveys)
