This article analyzes the major bidding brands, their comparative strengths and weaknesses, and the key factors behind Chengli’s successful bid—based on publicly available tender information and standard procurement practices. I. Project Background and Procurement Requirements The municipal sanitation department is located in Jilin Province and is responsible for sewage treatment within its jurisdiction. Its existing equipment has aged significantly and exhibits low processing efficiency; thus, a multifunctional sewage treatment vehicle is urgently required. Key procurement requirements included: - Chassis compatible with a 3308 mm wheelbase (commonly used by Dongfeng and Foton); - Capabilities for sewage suction, purification, and discharge; - Minimum single-batch treatment capacity of ≥5 m³; - Full compliance with China VI emission standards; - Delivery within 15 days. Based on local procurement conventions, the budget range was set at approximately RMB 315,000–338,000. II. Major Bidding Suppliers A total of three primary suppliers participated in this tender: Chengli Special Purpose Vehicle Co., Ltd., a well-known domestic sanitation vehicle manufacturer (referred to herein as “Company A”), and a regional distributor (referred to herein as “Company B”). All submitted vehicles meeting the technical specifications of model EHY5045TWCE6, but differed significantly in configuration and pricing. Chengli Special Purpose Vehicle Co., Ltd.: Offered customized model CLW5040TWCE6 (developed per EHY5045TWCE6 specifications), built on Dongfeng Automobile Co., Ltd. chassis, equipped with a fully automatic sewage treatment system, and quoted at approximately RMB 302,000 (per publicly disclosed tender data). Company A: Offered a same-wheelbase model built on Foton chassis, quoted at approximately RMB 360,000. Additional components (e.g., remote monitoring module) contributed to the higher price.
