Four departments issued a directory of guidance! Sany's device is on the list!

Recently，Ministry of Industry and Information Technology、Ministry of Ecology and Environment、Ministry of Housing and Urban-Rural Development、Announced by the General Administration of Market Supervision and Administration《Directory of low-noise construction equipment（The first batch）》，With green and low noise、Characteristics of energy conservation and environmental protection，Sanyi Road Machinery Meets China's Off-road Mobile Machinery“Guo Si”Emission standardsC10 Products——TrinitySPR300C-10HTire roller was selected successfully，Authoritative recognition。

“Identification of low-noise construction equipment”Jointly sponsored by the Ministry of Industry and Information Technology and the Ministry of Ecology and Environment，Designed to reduce noise pollution from construction equipment，Speed up the development and application of low-noise construction equipment，Guide the technical progress of construction equipment，Promoting high-quality development of construction equipment industry。

Selected this time《Directory of low-noise construction equipment（The first batch）》TrinitySPR300C-10HTyre roller，YesCThe masterpiece of 10 series tire roller。

Through the optimization and design of each system of the equipment，SPR300C-10HThe noise intensity generated by each system during the operation of the Road Roller is greatly reduced.，Uch as optimization of damping mechanism of Road Roller、Power system layout optimization、Fan optimization and matching optimization of hydraulic control system，Effectively improve compaction efficiency while reducing noise pollution。

Among，Engine is one of the main noise sources of Road Roller.。SPR300C-10HNew-type low-noise engine of Shanghai Diesel Engine Co., Ltd. is selected as the tire roller.，By optimizing the hood、Arrangement in the nacelle to improve the cooling air duct，Reduce the noise caused by air flow turbulence in the cabin；Optimize the diameter and shape of the intake and exhaust pipes，Reduce the noise generated by the intake and exhaust system during the operation of the engine，Add sound insulation around the cabin，Minimize outward transmission of power system noise。

At the same time，Through the adoption of SANY's self-developedTPATechnology，It can ensure that the customer is under normal construction conditions.，Noise near the driver's ear is less than 79dB(A)，External radiation noise 100dB(A)，At the same time, fuel consumption is greatly reduced.。

This timeSPR300C-10HGuide List of Tyre Rollers，It represents the Trinity Road Machine“Guo Si”C10 series technology is mature、And that construction is efficient、Green and safe、Stable and reliable，It is escorting the rapid realization of customer value in the industry。
