Tianjin Municipal Sanitation Units: Equipment Challenges Under High-Frequency Winter Operations. As a major northern Chinese city, Tianjin subjects sanitation equipment to severe winter conditions. A municipal sanitation department identified critical operational issues with its existing service vehicles during daily high-load operations—including difficult cold-weather starting and sluggish hydraulic system response—significantly undermining waste collection efficiency. By the end of 2025, the unit procured a batch of Ford Transit V362 service vehicles via public tender, intended for routine inspection, equipment transportation, and emergency support. Chengli Special Purpose Vehicles, leveraging deep understanding of Tianjin’s winter operating environment, delivered a tailored solution—ultimately supplying five units, now operating stably on main urban thoroughfares and community waste collection routes. High-Frequency Operation Pain Points: Fatigue Management and Low-Temperature Stability. According to feedback from the unit, average winter temperatures range from –10°C to –5°C, with service vehicles required to operate continuously for 8–10 hours per day. Legacy vehicles frequently exhibited the following issues: - Cold-start difficulty: Diesel engines suffered from fuel gelling, necessitating repeated preheating below –15°C. - Hydraulic line stiffening: Increased hydraulic oil viscosity led to delayed lifting and tipping actions. - Battery discharge: Frequent engine starts and prolonged headlight usage accelerated battery degradation. Chengli’s current solution prioritized freeze-resistant starting performance and hydraulic stability, ensuring efficient vehicle responsiveness even under extreme climatic conditions. Winning Solution Explained: Ford Transit V362 Service Vehicle Designed for Heavy-Duty Applications. The awarded model is based on the Ford Transit V362 chassis, modified as CLW5040XDWJ6 (referencing Chengli’s official announcement parameters). Key design features include: - Freeze-resistant starting system: Equipped with German-imported glow plugs and supplemented by cold-start fluid, achieving a verified 98% single-start success rate at –20°C. - Low-temperature hydraulic stability: Utilizes low-temperature hydraulic oil (pour point –35°C) and adds insulated hydraulic line sleeves to ensure smooth hydraulic operation in freezing conditions. - Reinforced heavy-duty chassis: Enhanced rear axle leaf springs increase load capacity by 15%, accommodating tools and spare parts transport requirements. Per local procurement conventions, the budget cap per service vehicle was approximately RMB 315,000. Through factory-direct sales, Chengli reduced the unit price to around RMB 260,000—saving roughly RMB 15,000 versus 4S dealership pricing (per publicly disclosed tender information).
