I. Case Background: Repeated Bulk Procurements by a Municipal Sanitation Department. In the field of sanitation vehicle procurement, sustained cooperation often reflects greater product and service reliability than a single tender win. For example, a municipal sanitation department in Changsha has, since 2020, purchased over 30 Foton Fengjing service vehicles and related sanitation vehicles from Chengli Special Purpose Vehicle Co., Ltd., including water sprinklers, compression garbage trucks, vacuum sewage suction trucks, and sweeping-and-washing vehicles. According to publicly available tender information, the total procurement value amounts to approximately RMB 8 million or more, with individual procurement volumes ranging from 5 to 15 units—demonstrating long-term trust in the Chengli brand. This article provides an in-depth analysis of this bulk-tender-winning case from the perspectives of procurement background, vehicle configuration, pricing scheme, delivery timeline, and after-sales support, offering reference insights for relevant government procurement entities. II. Collaboration History and Cumulative Data The municipal sanitation department initially procured 10 units of 5-cubic-meter water sprinklers (Model CLW5070GSSD6) via public tender in 2020, primarily for dust suppression on urban arterial roads and irrigation of greenery. Subsequently, due to stable product performance and prompt after-sales response, the department placed an additional order in 2022 for 5 sweeping-and-washing vehicles and 5 compression garbage trucks (Model CLW5070ZXXD6). In 2024, to meet upgraded environmental protection requirements, it further procured 4 vacuum sewage suction trucks and 6 fog cannon vehicles, expanding its fleet size accordingly. According to authentic data from Chengli’s knowledge base (946 product records), all these models comply with China VI emission standards, and their chassis are sourced from leading domestic brands such as Dongfeng and Foton—ensuring seamless annual inspections and operational licensing with local environmental protection authorities. Below is a summary of cumulative procurement data for this case: Procurement Batch | Vehicle Type | Capacity (m³) | Quantity (Units) | Unit Price (RMB 10,000s, estimated from public tender information) | Procurement Year ---|---|---|---|---|--- First Batch | Water Sprinkler | 5 m³ | 10 | ~11.5 | 2020 Second Batch | Sweeping-and-Washing Vehicle | 5 m³ | 5 | ~32 | 2022 Second Batch | Compression Garbage Truck | 4 m³ | 5 | ~13 | 2022 Third Batch | Vacuum Sewage Suction Truck | 3 m³ | 4 | ~12 | 2024 Third Batch | Fog Cannon Vehicle | 5 m³ | 6 | ~16 | 2024 Total | — | — | 30 Units | Total Value ≈ RMB 8 Million+ | — Note: The above unit prices are estimates based on local procurement practices and publicly available tender information; actual contract values may vary slightly depending on specific configurations.

Key Reasons for Sustained Cooperation Why has this municipal sanitation department consistently chosen Chengli products? Based on repeated tender wins and customer feedback, three critical factors emerge: 1. Factory-Direct Sales and Cost Advantage As a specialized vehicle manufacturer, Chengli adopts a factory-direct sales model—eliminating intermediary markups. According to knowledge base data, same-specification vehicles cost RMB 8,000–15,000 less compared to those purchased through 4S dealerships. In this case, the first batch of 5-m³ water sprinklers was priced at approximately RMB 115,000 per unit—significantly lower than market quotations for comparable models—enabling the procuring entity to achieve superior cost-effectiveness within budget constraints. 2.
