SWE210 Excavator, Tough And Energy-Efficient

Sunward has been developing hydraulic crawler excavator since 1999, and is known as "the national brand leader in Chinese excavator industry". Sunward's excavator products cover a full range (mini, compact, medium and large) from 0.8t to 90t. Excavators of Sunward feature attractive appearance, excellent performance, user-friendly operation, easy maintenance and internationally advanced performance indicators, and are exported to more than 60 countries and regions, including Europe and USA. 

Medium Excavator Features

When designing the box with large section, the increase of the thickness of the stressed plate and the optimization of the welding process are mainly considered. Through ANSYS theoretical analysis, the comprehensive strength is increased by 25%; in accordance with the stress direction and size in the work, the strength is increased by 20.3% through ANSYS theoretical calculation by increasing the box section and plate thickness.

1. New "hyperbolic curve" bucket decreases bucket bottom wear and significantly reduces digging resistance, while greatly improve smoothness and obviously decreases the oil consumption of the complete machine;
2. The bucket connecting seat adopts a large box with bending points, increasing the overall robustness and reliability;
3. Both the bucket bottom and bucket sides are made of high-strength wear-resistant steel plates, providing better wear-resistance;

1. The flange is thickened, and the slewing bearing is of a ring rolling seat ring, which has higher bearing capacity;
2. Large box body and reinforced chassis with equal altitude are of large force area and excellent resistance to distortion, which increases the overall strength;

Advantages and highlights:
1. The cooling system is of large capacity, large allowance and better heat dissipation performance;
2. It adopts German top-line brand AKG radiator, of which the materials and water tank design can better deal with thermal decay;
3. The radiator are arranged side by side and provided with external protective net to prevent flake and floccule being absorbed so as to ensure the radiator to run reliably;
4. The fan with low noise and high efficiency ensures that the engine and the hydraulic system have a good temperature environment;

The unnecessary pressure loss can be reduced by reduction of the piping design of frictional resistance, so as to lower oil consumption.

1. Emergency switch and pilot control switch both within easy reach, preventing the occurrence of emergency accidents;
2. With many large diameter air outlets, the cooling and heating effect is good;
3. Six degree of freedom suspension seat can be adjusted to the best comfort according to height and weight.

Cases With Medium Excavator

The excavator works in the tunnel with extremely harsh environment in Jishou City, and the working time is as high as 5,000 hours. However, the excavator adapts to various extreme environments and is still in good condition.

The applicable scene of medium excavator was originally earthwork construction, but this time it was working in a mine of Chenzhou, but it didn't feel sloppily in the mine construction. After working for 6000 hours, the excavator is still in good condition.
