Project Background: Sewer Cleaning Requirements in Tieling City, Liaoning Province In May 2026, the Municipal Engineering Office of Tieling City, Liaoning Province, faced severe siltation in its aging urban drainage network and thus initiated procurement of a batch of blue-plate sewer cleaning trucks for routine maintenance and emergency response. Following a public tender and comprehensive evaluation, Chengli Special Purpose Vehicle Co., Ltd. (“Chengli Auto”) secured the contract with its Dongfeng double-cab, 3-cubic-meter blue-plate sewer cleaning truck—recognized for regulatory compliance, rapid delivery, and outstanding cost-performance ratio. A total of five units were procured for pipeline cleaning operations across core districts including Yinzhou District and Qinghe District. Located in northern Liaoning, Tieling experiences winter temperatures as low as –30°C, imposing stringent requirements on cold-start capability, hydraulic system low-temperature resilience, and tank anti-freezing design. Additionally, the blue-plate classification—drivable with a Class C driver’s license—lowers staffing barriers and aligns with the municipal authority’s need for flexible workforce deployment. This handover documentation—including on-site photos and acceptance records—aims to serve as a practical reference for industry peers, demonstrating Chengli Auto’s end-to-end service capabilities from production to delivery.
