With refreshing autumn breezes and fragrant osmanthus blossoms, last Saturday marked the successful delivery of Mr. Wu’s third rear dual-axle cleaning and sewage suction truck — ordered from Mr. Zhang of Hubei Chengli. This is also his second unit purchased this year; each vehicle earns him at least RMB 1 million annually. While you hesitate, others are already profiting and ordering their fourth unit. The wealth gap is no coincidence: while you haggle over a few thousand yuan in price difference, others focus solely on delivering the highest-quality vehicle in the shortest possible time — generating over RMB 4,000 per day. Calculate for yourself: how much revenue do you lose by delaying your order? How much do you lose through frequent repairs with substandard equipment? This marks Mr. Wu’s fourth high-pressure cleaning and sewage suction truck ordered from Mr. Zhang Yue of Chengli. He purchased his previous unit — another high-pressure cleaning and sewage suction truck — in April this year. Due to rapidly expanding business volume, Mr. Wu contacted Mr. Zhang again in mid-October to order an even larger high-pressure cleaning and sewage suction truck. After detailed discussions, Mr. Zhang introduced Mr. Wu to the Dongfeng Tianlong chassis-based high-pressure cleaning and sewage suction truck and promptly sent him the detailed configuration specifications. Following thorough consultation, both parties finalized the configuration, signed the contract, and Mr. Wu paid the deposit. The Dongfeng Tianlong sewage suction truck ordered by Mr. Wu features the following specifications: Chengliwei high-pressure cleaning and sewage suction truck body mounted on Dongfeng DFL1250A13 chassis (original Dongfeng factory chassis), equipped with a new-generation cab, Fast Gear 8-speed transmission, 7-ton front axle, 10-ton rear dual axles, 11.00 steel-belted radial tires, Cummins 270 hp engine, and genuine China V emission compliance. Per customer requirements, the vehicle features an integrated tank design, Tianjin Tongjie 270L high-pressure pump, ~5 m³ clean water tank, ~15 m³ sewage tank, factory-installed air conditioning, and a Weichai 420 hp auxiliary engine. Key features of this Dongfeng rear dual-axle high-pressure cleaning and sewage suction truck include: SK-30 heavy-duty water-recycling suction pump, high-flow and high-pressure Tianjin Tongjie high-pressure pump — enabling full functionality for unclogging, cleaning, and sewage suction in a single vehicle. The tank is fabricated from 8 mm thick carbon steel plate, ensuring robust durability. With large tank capacity, high horsepower, extended continuous operation time, and convenient maintenance, this vehicle delivers dual functionality — saving both cost and labor while maximizing economic efficiency. Upholding Chengli Group’s consistent commitment to rigorous customer responsibility, Mr. Zhang personally oversaw this order closely — visiting the workshop daily to monitor production progress and inspect craftsmanship. Under skilled technicians’ expertise, the complete vehicle rolled off the assembly line within just fifteen days — a brand-new Dongfeng Tianlong high-pressure cleaning and sewage suction truck was ready for delivery. Mr. Zhang of Hubei Chengli promptly notified Mr. Wu upon completion. After arranging company affairs, Mr. Wu traveled to Hubei Chengli Special Purpose Vehicle Co., Ltd. with his driver. Having visited Chengli Group for the fourth time, Mr. Wu was already well-acquainted with our facility. Chengli Group’s sales manager guided him through comprehensive on-site testing — including water suction trials, functional verification, and quality inspection — all supported by Chengli Group’s technical team. The quality inspection was completed swiftly. Mr. Wu’s driver actively learned operational procedures for the new Dongfeng Tianlong cleaning and sewage suction truck. Once all operational instructions were thoroughly delivered, Mr. Wu expressed great satisfac
