SY1250 is a super-large digging product designed by Sany for mine. It adopts fully electronically controlled hydraulic system and Cummins power that have passed the market test, with high reliability and better operability.

Equipped with the top Cummins QSK23 engine in the industry, meeting EU stage ⅢA emission standard, with rated power of 567kW and strong power, it helps customers solve the difficult problems in harsh and heavy-duty `working conditions. The display screen displays the engine operation, maintenance and alarm information in real me, reminding and protecting in time, making maintenance more convenient. Optimize the engine universal characteristic curve, Sany’s original self-optimizing control technology, match the best fuel consumption area and control the fluctuation of speed, with lower fuel consumption and more stable work.

Fully electronically controlled hydraulic system: imported 280cc electronically controlled main pump+imported fully electronically controlled main valve form a fully electronically controlled hydraulic system, which is energy-saving, efficient and soft to operate; The conventional pump valve is used to form a parallel circuit, which increases the system flow, meets the requirements of super-large digging and large flow, ensures mature application and greatly reduces the failure rate.

Adoptsmulti-pump operation step-by-step control technology, rotary energy-saving control technology, load sensing control and other control technologies, which provides absolute help to improve the performance of the whole machine. The newly developed speed coupling control technology adopts a brand-new coupling control algorithm, which completely fits and improves the dynamic response of the engine and exerts the high efficiency of the high-horsepower engine.

Strengthened backhoe bucket: for the harsh workingconditions, increased capacity, optimized bucket type

The longest chassis of the same tonnage model adopts a 150-ton four-wheel belt with a large cross-section and high strength frame, which has the best long service life and stability.

Channels are connected left and right, and you can work from any side of the machine. Climbing ladders on both sides are arranged around the rotation center, and the whole machine rotates 180 degrees, so the climbing ladders on getting on and off can still correspond to the upper position, which does not affect people’s up and down operations. The anti skid convex points of the cover plate are integrally extruded, with stable structure and outstanding anti skid effect. Cover plates are arranged above and on the side of the main valve, which effectively protects the main valve from accidental impact.
