Government Procurement Case and Bid-Winning Solution Analysis for the Ford Transit V362 Service Vehicle in Hangzhou In the special-purpose vehicle procurement sector, the Ford Transit V362 chassis is widely adopted for its flexibility and reliability—commonly modified into various service vehicles for municipal, medical, and emergency applications. This article uses Chengli Special Purpose Vehicle Co., Ltd.’s delivery project in a southern provincial capital (hereinafter referred to as the 'Hangzhou Project') as a case study, analyzing the technical solutions and practical implementation experience of this model under humid, hot climatic conditions and high-frequency operational demands. I. Background and Core Requirements of the Hangzhou Project In 2025, a municipal sanitation department in Hangzhou planned to procure a batch of service vehicles based on the Ford Transit V362 chassis, primarily intended for road inspection, emergency repair, and material transportation. According to publicly released tender information, the total project budget was capped at approximately RMB 2.041 million, covering 10 complete vehicles—with an individual vehicle budget of no more than RMB 204,000. Key customer requirements included: • Anti-corrosion Coating: Vehicles must feature electrophoretic or anti-rust treatment on the chassis and critical components to withstand Hangzhou’s high-humidity, high-precipitation environment and prevent rust-related degradation of service life. • Sealing Component Durability under Humid-Hot Conditions: Door, window, and modified body sealing components must pass humid-heat endurance testing to ensure long-term resistance to aging and water infiltration. • Performance Under Rainy-Season Operational Load: Vehicles must maintain high-frequency deployment during prolonged rainfall periods, with stable and reliable engine, air-conditioning, and electrical systems. Leveraging its extensive experience in Dongfeng-chassis modifications (e.g., CLW5070GSSD6 model technical specifications), Chengli Special Purpose Vehicle integrated the Ford Transit V362 chassis with custom-built upper bodies, successfully delivering 10 fully compliant service vehicles. II. Technical Solutions and Bid-Winning Highlights To address Hangzhou’s humid-hot climate, Chengli’s engineering team implemented targeted enhancements beyond standard configurations: 1. Comprehensive Anti-Corrosion Coating: From Chassis to Modified Components Chassis: While the original Ford Transit V362 chassis already incorporates basic anti-corrosion treatment, Chengli applied additional electrophoretic coating to all exposed metal parts—including the modified body structure, mounting brackets, and fasteners—with a coating thickness of 80–100 μm, validated per China National Standard GB/T 10125 (Salt Spray Test). Customer feedback confirmed zero visible corrosion after operation throughout the 2025 plum rain season (40 consecutive days of rainfall). 2. Sealing Component Durability: Premium Imported EPDM Material Sealing strips at the interface between the modified body and chassis utilize imported EPDM (Ethylene Propylene Diene Monomer) rubber, combined with a dual-seal design capable of enduring temperature extremes from −40°C to +120°C and relative humidity up to 98%. Prior to delivery, Chengli conducted rain simulation tests (simulating torrential rainfall intensity) on each vehicle to guarantee zero leakage. 3. High-Load Performance During Rainy Season: Optimized Thermal Management and Drainage Systems A waterproof shield was installed in the engine compartment to prevent rainwater ingress; the air-conditioning condenser was repositioned laterally to minimize exposure to mud and water; and a dedicated drainage channel was added to the rear compartment to prevent water accumulation. According to project operation records, the 10 vehicles collectively accumulated over 5,000 operational hours during summer 2025 (June–August), with only one reported
