I. Project Background and Procurement Scenario In winter 2025, a newly established municipal sanitation department in Urumqi (hereinafter referred to as “the unit”) launched its first service vehicle procurement program to address the growing demand for emergency repair and routine inspection of sanitation equipment. The unit’s jurisdiction covers urban main roads and some suburban areas, where winter temperatures frequently drop below -25°C—imposing stringent requirements on the vehicle’s cold-start performance, low-temperature hydraulic stability, and overall operational maintenance capability. Per local procurement practice, the unit’s budget was capped at approximately RMB 386,000, with plans to procure two multi-functional service vehicles for rapid response to equipment failures, daily inspections, and light cargo transportation. Having no prior experience operating such vehicles, the unit needed to develop vehicle selection criteria, tender procedures, and post-delivery maintenance protocols from scratch. II. Selection Process from Scratch 2.1 Requirements Analysis and Technical Specifications The unit issued its procurement requirements via public tender, with core technical requirements including: • Cold-Start Performance: Vehicles must be equipped with a low-temperature preheating system to ensure reliable engine start-up at -30°C; diesel engines must operate on No. -35 diesel fuel. • Low-Temperature Hydraulic Stability: The hydraulic system must utilize low-temperature-resistant seals and specialized hydraulic oil, maintaining normal operating pressure even at -25°C. • Winter Maintenance Plan: Suppliers must provide a comprehensive winter maintenance manual covering battery insulation, antifreeze coolant specifications, and pipeline freeze-protection measures. • Vehicle Specifications: Cargo body length ≥ 4.5 m; payload capacity ≥ 1.5 tons; equipped with onboard tool racks and an integrated generator set. Additionally, per local procurement practice, the unit required the chassis to be branded Foton to leverage its nationwide warranty service network. 2.2 Chengli’s End-to-End Technical Consultation and Matching Chengli Special Purpose Vehicle Co., Ltd. (located at No. 1 Chengli Avenue, Suizhou Economic Development Zone, Hubei Province; official website: www.clspecial.com) proactively offered full-cycle technical consultation prior to bidding. Addressing Urumqi’s extreme cold environment, Chengli’s technical team recommended a service vehicle solution based on the Foton Fengjing chassis, featuring the following key configurations: • Engine Preheating System: Equipped with a fuel-fired heater enabling engine preheating down to -35°C, reducing start-up time to within 3 seconds. • Optimized Hydraulic System: Utilizes imported low-temperature-resistant seals and synthetic hydraulic oil rated for -40°C, ensuring zero leakage under sub-zero conditions. • Winter Maintenance Kit: Includes battery insulation cover, antifreeze coolant rated for -45°C, and pipeline heating tapes—provided free of charge with each vehicle. Chengli Sales Manager Zhang Yue (Tel: +86 ) held multiple technical coordination meetings with the unit’s engineering lead, delivering detailed technical documentation and committing to “original-chassis nationwide warranty, lifetime upfit support, and 24-hour direct shipment of spare parts”—effectively alleviating the unit’s concerns regarding cross-provincial after-sales service. III. Winning Proposal and Delivery Details 3.1 Core Configuration of the Awarded Solution Based on publicly released tender information, Chengli’s winning proposal covered two Foton Fengjing service vehicles, priced at approximately RMB 175,000 per unit, totaling ~RMB 350,000. Key vehicle specifications are as follows: Item Technical Parameter Chassis Model Foton Fengjing (China VI Emission Standard) Cargo Body Dimensions Length 4.8 m × Width 2.0 m × Height 1.8 m Payload Capacity 1.8 tons Engine Preheating System
