Be known as“Modern Highway Deep Milling Expert”YesCat®（Carter）PM620 milling machine has entered the Chinese market since 2017.，By being cost effective、Powerful、Convenient maintenance and popular with Chinese consumers，It has become a necessary artifact to deal with all kinds of harsh working conditions.。As the third edition of ChinaPMUpgrade of 620，The fourth edition of ChinaPM620 milling machine has emerged occasionally in the reconstruction and expansion project of Zhongbu Bridge in Hangzhou.、After a show of skill，He gradually unveiled the mystery that enveloped him.。

So，What are the features of this device?？What are the differences compared with the three national products?？

Mature, reliable and unique tail gas treatment system

As a leader in off-road low emission technologies，Caterpillar, with its engine technology，Ten years ago, it took the lead in introducing four-stage emission technology in the European and American markets.，He has accumulated rich experience over the years.，It is widely used in hundreds of thousands of non-road construction machinery around the world.，After more than 300 million hours of rigorous tests under various working conditions.。The technology is stable and reliable，Totally trustworthy。

Cat®（Carter）PM620 milling machine is still used in the fourth national new productCatIndependent brandC18 Engine，Because of its excellent dynamic performance and ultra-stable reliability，Widely used in a variety of earthwork and mining machinery and equipment.，Its mature four-stage exhaust emission treatment system has also been verified for a long time.。

  

PMThe exhaust emission treatment system of 620 adopts“DOC+DPF+SCR”The technical route，The operation efficiency and the liquid burning efficiency are well considered.，It can help users to reduce the use cost reasonably.。Caterpillar uses a uniqueDPFNon-inductive regeneration technology。When the soot is accumulated to a certain extent,，The machine will automatically start the regeneration system，Burn the soot out of it.。No shutdown is required for regeneration，Regeneration occurs automatically while the machine is in operation。Ensure machine availability。

    

Learn from others' strong points Inherit and develop the existing advantages

With the fourth national emissionCat PMThe 620 Milling Machine inherits the advantages of previous Caterpillar milling machines.，It is not only economical and durable，And the milling ability is particularly strong.，It can be regarded as an outstanding representative of the new generation of milling machines.。

PMThe 620 match isCatIndependent brandC18 ACERTEngine，Power reached473kw，Specific to the application characteristics of milling machines，PMThe 620 engine adopts optimized low-speed and high-torque power curve adjustment.。The slower the speed, the lower the fuel consumption.；The greater the torque，The greater the milling cutting force。This makesPM620 can easily cope with various working conditions，More fuel-efficient and efficient。

        

PM620 ownedCatPatented, one-of-a-kind automatic leveling system，And has high efficiency、Intelligence、Convenient use and the like.，YesCatA high-performance intelligent product developed by modern scientific and technological achievements。

Caterpillar is the first enterprise to carry out intelligent research.，PMThe 620 Auto Leveling System combines Caterpillar's numerous intelligent research efforts.，Make homework easier、More efficient，Including one-button plug-in milling mode、Automatic Ramp In Ramp Out Milling Mode、Obstacle-crossing milling mode、Compatible with 3DMilling mode, etc。

  

Optimize and upgrade Pursue higher efficiency

As a device with excellent performance，PMIn addition to inheriting the past, the 620 National Fourth Milling MachineCatIn addition to the advantages of milling machines，It has also been optimized and improved in many aspects.。

Optimized integration of rear leg sensors，In this way, the milling machine can always maintain the best posture in the milling process.，But also can further improve the milling precision and planeness.。

Meet the third national emissionPMThe 620 milling machine usesHalogen lighting，Meet the fourth national emissionPM620The whole car is standardLEDHigh brightness lighting lamp，This makes night construction more convenient.。

Adopted in the key parts of the conveying beltA new wear-resistant material，The service life of the machine is further improved。It is reported that，The service life of the new wear plate is 20% longer than the previous generation%Left and right。
