Recently，The Ministry of Industry and Information Technology announced《Directory of low-noise construction equipment（The first batch）》，Shandong LingongE6135HExcavator、E6205HExcavator、L968HLoader、RS826HRoad Roller、RS822HRoad Roller、RS626HRoad Roller、RS622HRoad Roller、G9180HGrader and other 8 products were successfully selected.。

In recent years，As the problem of noise pollution has become increasingly prominent.、The public's growing concern about noise，China is accelerating its efforts to prevent and control pollution in the field of noise.。“Identification of low-noise construction equipment”Jointly sponsored by the Ministry of Industry and Information Technology and the Ministry of Ecology and Environment，The purpose is to reduce the noise pollution of 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。

Declared by the enterprise、Recommended by provinces and cities、Expert review，A total of 46 products from 11 enterprises across the country have been publicized.，The number of temporary products selected is in the forefront of the industry.。

The selected low-noise construction equipment is only the representative of many temporary low-noise products.。Shandong Lingong insists“Customer-centric”The concept of development，Focus on customer driving comfort experience in the process of product development，Investment and construction of noise laboratory，Introduction of advanced noise analysis and detection equipment，Give full play to the advantages of industry-university-research cooperation platform，Active optimization of noise-related components，And greatly improve that control of the whole machine.、The body feels comfortable，Gain wide acclaim from users。

Temporary products are reliable.、Energy saving、Cozy、Intelligence and other core technologies have obvious advantages.，The four products of Lingong have improved the driving comfort.。

Wide field of vision：Cab is more spacious and bright，Operation Vision Improvement 15%Above，The driver doesn't feel tired after a day's operation.，The view is good，Work faster、More stable and safer.；

Within reach：Lingong products have abundant intelligent configuration，Not only are all the keys within reach,，More intimate cold and warm box，Driver friends can drink iced drinks in summer.，You can eat hot food in winter.。

Intelligent air conditioning：The air conditioner increases the cooling power、The air outlet is optimized，Prevent direct blowing of the joint，It solves the pain point of the driver's friend's long-term direct air conditioning.。

At the same time，Temporary workers are saving energy、Noise reduction also leads the development of the industry。Decomposing noise source by temporary analysis，Formulate measures to reduce noise item by item。Enterprise standards for noise limits that are stricter than national standards and regional requirements such as the European Union have been formulated.。The product emits noise、The noise near the driver's ear meets and is lower than the national standard limit.。

Cooperation Platform between Lingong Utilization and University Industry-University-Research，Powertrain mount optimization based on independent development of Lingong、Noise、Vibration source component optimization、Component Modal Optimization、Fluid simulation、Ergonomics and other core technologies，By using the vibration spectrum of the whole machine(FFT)、Vibration source transfer path analysis(TPA)、Holographic imaging and other advanced detection methods，Ffectively improve that working environment of the operator，And that comfort of the whole machine is improve.。Domestic 5TLoader outside cab noise from 87dBDown to 81dB，L958FLoaders and other products won the European Union.CECertification，The noise in the cab is reduced to 80dBFollowing；Medium excavator outside the cab noise from 79dBDown to 71dB。

 

Next step，Lingong will continue to improve the management system of noise pollution prevention and control，Optimize product development，Steadily improve driving comfort，Continuously improve the quality of acoustic environment，Create the most popular product experience for users，Win“Reliable、Energy saving、Cozy、Intelligence”Four word of mouth。
