STC250E5-1 (plug-in) and STC250BEV have passed the national authoritative inspection!

The other day，“2022TOP50”Guidance UnitNational Construction Machinery Quality Inspection and Testing Center，Yes, previously won“New Energy Gold Award”YesSTC250E5-1（Plug in）、STC250BEVPerformance tests were conducted.。September 1，Test report officially released，Two products have passed the national authoritative inspection.。

Test referenceGB/T 39416-2020《Test method for fuel consumption of Truck_crane/ 'target='_blank' style='color:blue;'>Truck Crane》AndGB/T 20062-2017《Limits and measurement methods of noise emitted by mobile crane in operation》，Standby for both products、The outrigger is telescopic、Extension and retraction of main boom、Luffing、Turn around、Power consumption shall be carried out separately for lifting and other working conditions.、Fuel consumption and noise test。

The test results show，STC250E5-1（Plug in）Power consumption mode: electric energy consumption per hour is 20 kW·h，Fuel consumption for operation in oil mode is 11.17 L/h。At an oil price of 8 yuan/Liter，The electricity charge is 1 yuan/Degree calculation，It can save about 69 yuan per hour on average.。During the actual use of the product，The ratio of electricity consumption to fuel consumption approaches 1:3，Fuel saving performance is more ideal。In addition，Power mode operation is quieter than oil mode operation。

As a new energy benchmark for the crane industry，Sany actively promotes the electrification of mainframe products and the development of related core technologies，Fully start the electric transformation。Among，STC250E5-1（Plug in）It is the representative work of crane electrification.。It has been listed since October last year.，It has achieved more than 800 proud achievements.。

The plug-in crane has a dual-power operating system，Plug-in mode 380VDirect drive，Convenient to use，Less user input，And that economic benefit is high，It is mainly applicable to monthly and fixed operation scenarios.。Under the background of existing battery technology and market，The market recognition of plug-in products is high.。

At present，Sany refers to the mainstream technical route of commercial Vehicles，Except plug-in，And pure electric and hybrid.，Multiple technical routes go hand in hand，12 tons covered、25 tons、35 tons、50 tons，It is the benchmark of new energy technology in crane industry.，Driving the application and development of new energy products in the industry。

The world's first licensed pure electric craneSTC250BEVIt has also shown its due level in this experiment.，Power consumption per hour under operating conditions 32.88kW·h，Power consumption of 30km constant speed 100km 101.6kW·h，Endurance 226km。Operation noise is 5% lower than that of oil-fired crane%，In line with zero emission in some areas、Requirements for low noise。This model establishes the optimal technical route of off-highway pure electric transport equipment.，It effectively solves the economic problem of large-scale application of pure electric technology.。

At“Double Carbon”Under the guidance of the goal，Electrification of construction machinery is no longer a choice question，And became a required question.。In the changing times，Accelerating the Entry of Industry Electrification“Fast lane”，It is the responsibility of industry leaders like Sany.。
