Sany Heavy Industry: If excavators have a certain grade, they are definitely from Tsinghua and Peking University. They are both cost-effective and profitable. If you don't believe it, come and fight!

As the saying goes, "Every trade has its champion." In our excavator industry, there is such a model, the SY335, which is widely recognized as a top student. Whether it is from the actual test performance or the hardcore configuration, there is no doubt that it has the potential to be from Tsinghua or Peking University. What exactly makes "other people's excavators" so outstanding in everyone's eyes?

Whether the excavator is good or not can only be known by pulling it out and comparing it

In the actual excavation tests, SY335H performed outstandingly in both stonework and earthwork operations.

It can load an additional 38 tons of stone materials per hour. Calculated based on 2,000 working hours a year, it can load an additional 76,000 tons annually. It can save 3.65 liters of fuel per hour. Calculated based on 2,000 working hours a year, 7,300 liters can be saved annually.

The annual comprehensive income can increase by more than 200,000 yuan

Note: Diesel is calculated at 6.96 yuan per liter

Each ton of stone material spread evenly on the excavator is calculated at 2 yuan

Fuel consumption efficiency comparison

Under the earthwork conditions in mining operations, taking the commonly used S8 gear as an example, the SY335H can load an additional 25 cubic meters of soil per hour, which is equivalent to 1.5 vehicles (16-cubic-meter vehicles). Calculated based on 2,000 working hours per year, it can load an additional 3,000 vehicles annually. It can save 1.5 liters of fuel per hour. Calculated based on 2,000 working hours a year, 3,000 liters can be saved annually.

The annual comprehensive income increased by more than 125,000 yuan

High efficiency and energy saving

SY335H is a 33-ton earthmoving excavator (Loading King) that Sany Heavy Machinery has been focusing on launching in 2020. It is specially designed for earthwork loading and excavation. It adopts load adaptive technology and bucket control technology. Through a series of measures such as "optimization of the main pump control curve, bucket shape optimization, and improvement of coordination", it has achieved dual breakthroughs in "reducing fuel consumption" and "improving efficiency"

By analyzing the action load and identifying the working conditions, the torque is automatically adjusted. When the load is large, the power of the main pump is automatically increased to raise the digging speed of the bucket and boom by up to 10%

Optimize the I-Q curve, reduce the pump displacement at the same current, and achieve fuel savings of more than 10%

The control is achieved by using a bucket-stem electric control valve core: under low pressure (light load) conditions, the valve core is semi-open for control, and the flow is recycled to achieve energy-saving purposes. The valve core in high-pressure (heavy-load) state is fully open for control, reducing the back pressure of the return oil, enhancing the efficiency of the main pump, and lowering fuel consumption, achieving fuel savings of over 5%. Eliminating the priority valve of the boom against the bucket rod: the pressure loss caused by throttling is eliminated, and fuel consumption can be further reduced by more than 5% on the basis of the original fuel-saving of the electrically controlled valve core
