I. Case Background: Service Fleet Procurement Requirement of a Municipal Sanitation Department in Ningbo In 2025, the Urban Management Bureau of a district in Ningbo planned to procure a batch of Foton Fengjing service vehicles to ensure efficient operation of sanitation operation vehicles within its jurisdiction. These vehicles are intended for daily inspection, emergency repair, and spare parts transportation. They must feature high reliability, ease of maintenance, and adaptability to Ningbo’s coastal climate—characterized by high humidity and frequent rainfall. According to publicly released tender information, the project budget is capped at approximately RMB 335,000, with three service vehicles to be procured at an estimated unit price of around RMB 95,000. The client specifically emphasized the need to provide a complete list of consumable spare parts and a comprehensive spare parts supply plan to minimize long-term maintenance costs. II. Core Elements of the Spare Parts Procurement-Based Solution This procurement adopts a 'spare parts procurement-based' solution, focusing on resolving long-standing issues faced by municipal sanitation departments—including non-transparent spare parts pricing and untimely supply. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli'), leveraging its mature supporting system for sanitation models such as the CLW5070GSSD6, customized a spare parts solution for the client. Key elements include: Transparent Consumable Spare Parts List: Chengli provides a standard consumable spare parts list covering filters, brake pads, seals, belts, etc., with unit prices referenced to factory production cost—eliminating markups typical of 4S channels. For example, the air filter for the CLW5070GSSD6 chassis is priced at approximately RMB 150, significantly lower than market intermediary prices. Spare Parts Price Transparency: Chengli commits to full price disclosure for all spare parts, with no bundled pricing. Clients may directly inquire about prices based on the consumable spare parts list—for instance, a front-wheel brake pad assembly is priced at approximately RMB 420, and a full-vehicle seal kit at approximately RMB 520 (final pricing subject to contract). Durability of Spare Parts Under High-Load Conditions: To address Ningbo’s humid and hot environment, Chengli enhanced anti-corrosion coating and seal durability on the service vehicles. The chassis employs galvanized steel plates and anti-rust paint, while seals utilize rubber materials resistant to humidity and heat—ensuring minimal rust or leakage during frequent rainy-season operations. Per official CLW5070GSSD6 technical specifications, this model features an enhanced corrosion-resistant chassis design. III. Chengli’s 24-Hour Direct-Shipment Service vs. Traditional 4S Channels In terms of spare parts supply efficiency, Chengli offers a 24-hour direct-shipment service, delivering clear advantages over conventional 4S channels.
