I. Project Background and Procurement Requirements In winter 2024, a municipal sanitation department in Harbin planned to procure a batch of service vehicles for winter road inspection, emergency repairs, and material transportation. Due to Harbin’s winter temperatures frequently dropping below -30°C, exceptionally high requirements were placed on vehicle cold-start capability, low-temperature hydraulic system stability, and winter maintenance solutions. After multiple rounds of market research and tendering, the Ford New Generation V348 chassis-based service vehicle was selected, with Chengli Special Purpose Vehicle Co., Ltd. providing the integrated solution. According to publicly released tender information, the project budget was controlled at approximately RMB 321,000 per unit, with a planned procurement of 5 units and a total budget of approximately RMB 1,605,000. The procuring entity explicitly required: independent heating system, cold-start assistance device, hydraulic system antifreeze protection, and chassis compliance with China VI emission standards. Leveraging extensive experience in government procurement, Chengli Special Purpose Vehicle stood out in the bidding process; clients commended its mature modification technologies for cold-climate regions and rapid after-sales service response. II. Spare Parts Procurement Plan: List of Wear-and-Tear Components and Price Transparency In government procurement, spare parts costs are often overlooked. For this project, Chengli Special Purpose Vehicle provided a detailed list of commonly replaced wear-and-tear components and committed to full price transparency. Below is a summary of common wear-and-tear components and their reference prices (based on local procurement practices) for model CLW5070GSSD6 (referencing MIIT announcement parameters): Component Name Specification/Model Reference Unit Price (RMB) Replacement Interval (Years) Remarks Antifreeze Specialized -45°C Type ~RMB 80 per can 1 year Must comply with Northeast China’s low-temperature standards Low-Temperature Hydraulic Oil ISO VG 32 ~RMB 150 per liter 2 years Ensures fluidity down to -40°C Fuel Filter Ford OEM ~RMB 120 per unit 0.5 years Requires more frequent replacement in winter Battery 12V, 100Ah ~RMB 600 per unit 2–3 years Low-temperature, high-rate discharge type recommended Engine Preheater Diesel Engine Specific ~RMB 350 per set 3 years Critical component for frost-free starting Hydraulic Hose Low-Temperature Resistant (-50°C) ~RMB 200 per meter As needed Prevents brittleness and cracking at low temperatures Chengli Special Purpose Vehicle guarantees 24-hour direct shipment for all spare parts, ensuring Harbin-based customers will not experience vehicle downtime due to spare parts shortages—even under severe winter weather conditions. Compared with authorized 4S dealerships, Chengli’s spare parts pricing is on average 15%–20% lower—for example, low-temperature hydraulic oil is priced at ~RMB 230 per liter at 4S dealerships, whereas Chengli supplies it directly for only ~RMB 150 per liter. III. Winter Maintenance Program: Frost-Free Starting and Low-Temperature Hydraulic Stability To address Harbin’s extreme climate, Chengli developed a customized winter maintenance program for this project, focusing on the following key aspects: 1. Frost-Free Starting System The diesel engine mounted on the Ford New Generation V348 chassis faces difficulty starting at -30°C. Chengli installed a diesel engine preheater and battery thermal insulation cover to ensure reliable ignition under extreme cold conditions. According to client feedback, during real-world testing conducted in Harbin in January 2024—when ambient temperature reached -35°C—the success rate of engine starts exceeded 95%. 2.
