Engineer Liu's 10 products are on the list! Leading the era of low noise and comfort!

Low-noise construction equipment

The first batch of guidance directory was released.

Recently，Ministry of Industry and Information Technology、Ministry of Ecology and Environment、Ministry of Housing and Urban-Rural Development、Four departments of the State Administration of Market Supervision and Administration jointly issued《Directory of low-noise construction equipment（The first batch）》，Engineer LiuLoader、Excavator、Motor GraderTotal10 devicesWith strong technical accumulation and low noise、Comfort and other superior performance glory on the list。

To further improve the performance of the whole machine，Where is Liugong R & D team?Vibration、Noise、SmoothingStudy hard on it，Keep breaking through：

Through advanced simulation and test technology，Accurately locate the noise source of the whole machine，Accurate identification of key transmission paths of vibration and noise。

Noise reduction by exhaust system design、Transmission Housing and Tooth Profile Optimization、Sound Field Design and Optimization of Cooling System、Reasonable matching and control of pump and valve、Air conditioning duct flow field optimization and other technologies，The power chain is realized from the source.、Heat dissipation、Hydraulic、Vibration of air conditioning and other systems、Effective control of noise。

Through forward design and overall optimization，The transmission of structural and airborne sound into the cab is significantly attenuated from the transmission path，Significantly improved cab comfort。 

Relevant information

In order to implement《Noise Pollution Prevention and Control Law of the People's Republic of China》，Do a good job in noise pollution control，Reduce the impact of construction noise on people's daily life、Impact on and injury to the health of field staff，Promoting high-quality development of construction equipment industry，《Directory of low-noise construction equipment》Focus on the source of construction noise，The technology of noise detection by batch selection is relatively mature.、Quieter construction equipment，Speed up the development and application of low-noise construction equipment，Guide the technical progress of construction equipment，Continuously reduce the noise generated during construction，Reduce interference in areas where noise-sensitive buildings are concentrated。

The recommended scope of the first batch of low-noise construction equipment is earth-moving machinery.，Therefore, the construction equipment noise management system and management system are established.，The noise value of the declared product is superior to the national standard.（《Earth-moving machinery--Noise limit》GB 16710-2010）Request。
