After years of working with all kinds of devices,
Found that everyone has martial arts skills.
That's the top stream in the Excavator.
It's time for real technology.
Flagship configuration，Leapfrog performance，Technology is one step ahead of others.
Guo SiSY215CAlmighty KingJust to be stronger.
Stronger than you think.、More efficient、More energy efficient！
SY215CIt is a 21 made by Sany Heavy Machinery.TGrade III earthwork Excavator products，ItsHigh power、And that reliability is high，Has won the annual product of China's construction machineryTOP50“Golden Finger Award”，It is an all-round model with excellent performance.。SY215CAround the fourth national aircraft“New Power”、“New look”、“New technology”Full upgrade，ItsAdopted HOPE Full electronic control technology，The control performance of the whole machine is greatly improved.，It can meet the operation requirements of customers under different working conditions.。New PowerPower system：With Mitsubishi Fuso 4M50 engine，Rated power up to 118kW，The torque is large、High durability，Faster dynamic response。Adopt EGR+DOC+DPF Technology，Realize precise control of intake flow and fuel injection quantity，Meet the fourth national emission standard，Reduce fuel consumption and emissions。
Hydraulic system：Equipped with Kawasaki main valve and Kawasaki main pump，By optimizing the control strategy，Achieve arm regeneration and fast oil return，And precisely control that valve core at the same time.，It improves the energy efficiency and control performance of the whole machine.。
Displacement of plunger pump：From 112ccIncrease to 125cc，UniversalLift 5-10%，Increased range of available engine speeds，Easier to operate in economical fuel consumption area。New upgrade 14DReducer：The slewing ability is improved，Greater slope work capability，Speed up the start of swing。Slewing deviceLift 12%Slewing capacity。The driving force of machine swing is increased，Improved ability to work on slopes，Speed up the start of swing。
New look
Control upgrade：Upgrade again with 10-inch large screen，Thinner、More dazzling、Clearer。In-Vehicle wireless local area network，Support 4GNetworkOTAUpgrade，Faster and safer。
c12 Driver's seat：Sany cooperates with well-known automobile design companies，The cab will be upgraded from appearance to user experience.，Follow“Comfortable and convenient、Automatic intelligence、Netcom ecology”The idea of，Build one for the customer“First class”Like a driving environment。
New air conditioning system：Equipped with new air conditioning system，Cooling effectStronger，Air volume distributionMore reasonable。Air conditioning filter element for in-car cleaning and maintenance，Cleaning is simpler。
New interior：The interior has been fully upgraded，Narrow armrest box、Minimalist front control box，Water cup holder as standard、12VPower port、USBInterfaces, etc，Automotive quality interior。Comfortable and shock-absorbing seat，And that vibration comfort is improve。
Improved security：Stop the lamp at night and delay the extinguishment、One-key switching of forehand and backhand display screen、Rear camera and other configurations，Ensure driving safety。
New technology
Bucket upgrade：Standard Earth Bucket，Optional rock bucket，Realization“One situation, one bucket.”，Meet the operation requirements of different working conditions。Optimize the bucket shape，Increase the fluency of material penetration，Reduce friction。The included angle between the front edge plate and the bottom plate of the support increases.，Increase the full bucket rate。Reduction of average resistance during excavation，And that excavate efficiency is improved。
Full electric control hydraulic system：AdoptHOPEFull electronic control technology，Development and application of high performance electro-proportional control main valve，Realize the accurate control of the controller to the valve core.，Improve the energy efficiency and maneuverability of the whole machine。New hydraulic circuit，Reduce the loss of oil return power，Establish optimal control，High power transfer rate，High efficiency、Low fuel consumption。
Swing flow control：Swing speed sensor is built in the controller，By collecting the value of the slewing speed，Controls the pump flow during swing acceleration，Reduce the rotary overflow flow，Reduce fuel consumption，Slewing starting impact is small、The acceleration process is smooth。
Operational efficiency：Coping with leveling operation，The efficiency of leveling is goodLift 17%。Dealing with loading and dumping operation，Turn around+The boom is lowered+When the arm is unloaded and returned，The efficiency is goodLift 23%。
