Hubei Chengli sweeper-scrubber trucks are among the most advanced municipal sanitation equipment, integrating road sweeping, waste collection, and transportation into a single high-efficiency system. They are widely used on expressways, municipal roads, airport runways, urban residential neighborhoods, parks, and similar road surfaces. Beyond debris removal, these sweepers also purify airborne particulates along roadways—ensuring road aesthetics, maintaining environmental cleanliness, preserving optimal pavement conditions, reducing and preventing traffic accidents, and extending pavement service life. Sweeper trucks significantly reduce manual labor intensity for sanitation workers, improve operational efficiency, and minimize secondary pollution such as dust generation.   Last Saturday, Mr. Wang from Shandong—a client who previously visited our factory for inspection—finalized his order for the Dongfeng Tianjin sweeper-scrubber truck after thorough evaluation and discussion. In late October, Mr. Wang and his team visited Chengli Group’s manufacturing facility in Suizhou, Hubei. They were highly impressed—not only by Suizhou’s scenic beauty and local cuisine—but also by Chengli Group’s large-scale production capacity and the professionalism of General Manager Zhang, whose meticulous attitude and profound technical expertise left a lasting impression. Since the vehicle is intended for use in a coal mine—an environment with unique operational demands—Mr. Wang’s team deliberated extensively on model selection. Following detailed, expert explanations from General Manager Zhang, they selected the optimal configuration: the Hubei Chengli Dongfeng Tianjin sweeper-scrubber truck. A formal contract was signed and a deposit paid to secure the order. Fortunately, this particular model was available in stock. After several days of final configuration, system commissioning, and documentation processing, the vehicle is now ready for delivery—marking another successful collaboration between Dongfeng Tianjin and its Shandong ‘Bole’ (a metaphorical reference to a talent-spotter or discerning client).    This morning, prior to dispatch, the Dongfeng Tianjin sweeper-scrubber underwent comprehensive functional demonstrations—including high-pressure front flushing, combined sweeping-and-scrubbing operation, rear misting for dust suppression, automatic self-cleaning of the wastewater tank after discharge, and handheld high-pressure jet cleaning. General Manager Zhang informed Mr. Wang that the vehicle would be dispatched this afternoon, and the Hubei Chengli sweeper-scrubber is expected to arrive at Mr. Wang’s coal mine tomorrow.  The model ordered by Mr. Wang is built on the Dongfeng Tianjin 5000 mm wheelbase chassis, powered by a Cummins 180 hp main engine and a Cummins 170 hp auxiliary engine, equipped with 900R20 steel-belted radial tires and a high-torque hydraulic motor. It features a German-made high-pressure pump (for front flush, side spray, center spray, rear misting with stainless-steel nozzles, side rinse gun, and self-cleaning function for the waste bin), omnidirectional high-pressure curb cleaning, a Taiwan-made hydraulic valve bank, a Weilong low-pressure pump (for front flush), stainless-steel high-pressure piping, a dual-layer stainless-steel suction drum, a German-made control unit, U.S.-made sensors, rear arrow indicator lights, and overflow/low-level alarm systems for engine oil, waste bin, and water tank. Additional features include an in-cab monitor for reversing and sweeping operations, automatic anti-collision protection during reverse maneuvers, safety interlocks for maintenance, wear-resistant high-performance engineering bushings on brush arm pivot mechanisms (eliminating the need for grease lubrication), and a 20-meter high-pressure hose reel. An integrated motion controller enables one-touch computerized operation. Configuration: 9-water / 7-dust system, featuring two centrally moun
