When facing the great test of the mineNot only to pursue“Strong and durable”“Strong digging force”More to look for cost-effective“Hexagonal warrior“SY550HModel specially developed for mine constructionOverall performance is upgraded againMeet the overall needs of the mine

Is the so-called strength to see the real chapter, whether an excavator is good or not, the old iron has the final say.

New upgrade·Soldier of steelSY550HIt is a 50 made by Sany Heavy Machinery.TClass Super Mining Excavator Product，Specially designed for heavy load conditions in mines，As a mining classic excavator，Its performance is excellent、Excellent performance，Awarded China Construction Machinery“TOP50 Gold Award for Application Contribution”。

A whole new generationSY550HAround the fourth national aircraft“New Power”、“New look”、“New technology”Full upgrade，Powerful、The control is humanized，Meet a variety of operational needs。

Hydraulic system：Fully electronically controlled main valve and main pump of famous brand，Main pump displacement from 212ccUpgrade to 240cc，Adopt main valve core with 36 large diameter，The system pressure loss is reduced，More efficient，Lower fuel consumption。

Power system：It is equipped with Sany customized imported engine.，Rated power 310kW，Within the effective working range，Sufficient torque reserve and smooth output，Help customers solve problems under heavy load conditions。AdoptDOC+DPF+SCRPost-processing technology，The urea pipeline is electrically heated.，Fuel consumption is reduced，Discharge clean，More environmentally friendly，Bring real benefits to customers。

Bucket upgrade：Standard 3.2m³Dadou，Available with 3.5m³Super big bucket，It is suitable for the harsh working environment of mines and the working conditions of loading gravel and granite.，The construction of the wear plates ensures a longer service life。

Four series of buckets can be configured，Satisfy“One situation, one bucket.”，And that construction efficiency is improve，Easily deal with a variety of complex working conditions，Increase product value and customer profitability。

Boom Stick Upgrade：Full application of 20,000-hour working device technology，Nsure high reliability of the working device、Longer life。The case structure of the boom and arm is enlarged and widened.，Built-in multi-channel inner rib plate，Application of high-strength material，Through the full data test of the actual mine conditions and the rigorous durability test，Ensure its high reliability。

AOCTSelf-optimizing control system：AdoptAOCTSelf-optimizing control technique，According to different working conditions，Each gear is realized.、All modes work in the best fuel consumption area of the engine.、Main pump high volumetric efficiency region，Perfect matching between engine and main pump，Thereby achieving high efficiency.、Excellent performance with low fuel consumption。

Get off at the mine：Design of Heavy Duty Four Wheels and One Belt for Mine，Heightening of main frame section，Track guard structure reinforcement，Strong and wear-resistant，Stable and reliable。The track is made of high-strength special steel rolled three-toothed plate.，And that ground property is better、And that stability is high、Increased durability。
