The SUM7200D asphalt concrete paver of Shaanxi Construction Machinery Co., Ltd. has successfully completed the type test

From August 29th to 31st, 2023, the Road Construction Machinery Testing Center of Chang 'an University conducted type tests on the SUM7200D asphalt concrete paver independently developed by Shaanxi Construction Machinery Co., Ltd. at the construction site in Huizhou, Guangdong. The tests confirmed that: The design performance indicators of the SUM7200D asphalt concrete paver comply with the provisions of the GB/T 16277-2021 standard "Asphalt Concrete Pavers for Road Construction and Maintenance Machinery and Equipment".

The SUM7200D asphalt concrete paver is a brand-new platform model developed by Shaanxi Construction Machinery Co., Ltd. to meet the new emission standards. It adopts the National IV engine for non-road mobile machinery and is equipped with a single hammer electric heating telescopic screed. The designed maximum paving width is 9 meters, the maximum paving thickness is 300 millimeters, and the hopper capacity is 15 tons. The whole machine is equipped with a multi-dimensional operating system, an automatic cruise system, a voice recognition system and an intelligent electric heating control system. By applying operation quality improvement and mechanical, electrical, hydraulic and information control technologies, it can easily achieve many practical construction functions such as automatic hydraulic tensioning of the track, multi-speed overall lifting of the material feeder, and quick connection of the extended section. While improving construction efficiency, it can quickly realize the one-time formation of the road surface Effectively solve the segregation problem during paving construction and perfectly meet the surface layer construction requirements of national second-class and above highways and municipal roads with variable road widths.

The successful passing of the type test of the SUM7200D asphalt concrete paver this time is not only the continuation and inheritance of the enterprise spirit of "perseverance and excellence" adhered to by the technological innovation team of Shaanxi Construction Machinery Co., LTD., but also a symbol of the return of the SUM series pavers as the king.
