Rise up one after another, overcome obstacles! The new generation SY255H strikes with great power

In 2021, Sany made great efforts to build and launched a 25T-class hydraulic excavator - SY255H DPC.

It is suitable for medium and large-scale earthwork loading operations, urban renovation operations, and building/plant foundation excavation operations, with the goal of improving customer investment returnsHigh excavation strength, high efficiency, low fuel consumption, high reliability, excellent handling, standard 1.4 square bucket capacity, resolute and tough mine shape, which is bound to show its skills in the market.

Customized imported engine

Customized imported Mitsubishi six-cylinder engine,Strong power, reliable quality, more stable operationThe power reserve coefficient is large, and the electronically controlled common rail fuel injection system is used to accurately control the amount of fuel injection in real time, so that the fuel combustion is more sufficient, and the universal characteristic curve is optimized to ensure lower fuel consumption in the working area, and more economical and environmentally friendly.

A new generation of electronically controlled pumps

The use of a new generation of hydraulic system (electronically controlled positive flow system), higher than similar products in the industry, the use of efficient electronically controlled pumps, can be realizedA variety of control methods, high control accuracy, sensitive system response, better response； Through program control, the flow matching during compound action can be flexibly realized, and good coordination can be achieved, and the operation of the whole machine is soft and sensitive.

A new generation of electronically controlled valves

A new generation of electronic control valves is adoptedPrecise control, good micro-movement, small system pressure loss, more energy savingAt the same time, the open circuit is realized to make the operability good and the efficiency is higher.
