Case Background: Winter Operation Pain Points of Sanitation Vehicles in a District of Taiyuan City. During the winter of 2025, a municipal sanitation department in Taiyuan (hereinafter referred to as the 'Client') faced frequent failures of aging service vehicles under low-temperature conditions. The original vehicles experienced difficult cold starts and sluggish hydraulic system response below -15°C, directly impacting daily cleaning operation efficiency. The Client urgently required procurement of a batch of service vehicles equipped with frost-proof starting capability and low-temperature hydraulic stability to meet winter operational assurance needs in Taiyuan’s severe cold climate. Following a public tender process, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') delivered six units of Ford Transit V362 service vehicles (model reference: CLW5070GSSD6, upgraded chassis version), with a total budget of approximately RMB 2.01 million (per publicly disclosed tender information) and an average unit price of around RMB 300,000. This article analyzes the vehicle’s performance in terms of operational efficiency improvement, workforce optimization, and cost control, based on actual usage data. Comparative Data Before and After Deployment. According to data provided by the Client, deployment of the Ford Transit V362 service vehicles significantly improved the previous operational model. Key performance indicators are summarized below: Indicator | Legacy Vehicle (Pre-deployment) | Chengli Ford Transit V362 (Post-deployment) | Improvement Rate Daily Operating Distance (km/unit) | 45 km | 68 km | +51% Cold-Start Success Rate at -15°C | 72% | 98% | +26% Hydraulic System Response Time (seconds) | 5–8 sec | 2–3 sec | +60% Daily Personnel Allocation per Unit (persons) | 3 persons | 2 persons | Reduction of 33% Average Monthly Maintenance Frequency per Unit | 4 times | 1 time | Reduction of 75% Average Monthly Fuel Cost per Unit (RMB) | ~RMB 3,600 | ~RMB 2,800 | Reduction of 22% Note: Data sourced from the Client’s operational records from December 2025 to February 2026, referencing publicly disclosed tender information and local procurement practices. Increased Daily Operating Distance: Frost-Proof Starting and Low-Temperature Hydraulic Stability Are Key. Taiyuan’s winter temperatures frequently drop below -10°C. Due to insufficient engine preheating and hydraulic oil solidification, legacy vehicles achieved only an average daily operating distance of 45 km. The Ford Transit V362 service vehicles delivered by Chengli—built upon Dongfeng chassis—feature a low-temperature starting assistance system (e.g., glow plugs and pre-heaters), ensuring rapid cold starts even at -20°C. Client feedback indicates a cold-start success rate of 98% at -15°C, representing a 26% improvement over legacy vehicles. Additionally, the hydraulic system employs low-temperature-resistant hydraulic oil and insulated piping, reducing response time from 5–8 seconds to 2–3 seconds, thereby enhancing operational efficiency for sweeping, watering, and other tasks. Daily operating distance increased to 68 km—a 51% gain—ensuring timely completion of winter sanitation tasks. Workforce Optimization: Reduction in Crew Size per Unit from Three to Two. Legacy vehicles, due to complex operation and high failure rates, required three personnel per unit (driver, operator, and assistant). The new Ford Transit V362 service vehicle integrates an intelligent control system enabling the driver to perform watering, sweeping, and other operations via one-touch commands on the central control display, minimizing manual intervention. In practical use by a street environmental maintenance unit in Taiyuan—consistent with local procurement practices—the vehicle operates with only two personnel per unit.
