With the redefinition of China's urban construction process by the "new urbanization" strategy, the demand of China's construction machinery market is also quietly changing. Wheel-type excavators have attracted more and more attention in the industry and become one of the strategic development products of many leading construction machinery enterprises.

The wheel excavator is a kind of construction type wheel and tire walking excavator with fast walking speed, long-distance self-transition and quick replacement of various operating devices. The advantages of mobility, flexibility and efficiency have won customers' favor. At present, the driving speed of foreign wheel excavators is mostly 25-40 km/h, and most of the domestic wheel excavators are 20-35 km/h, some of which can even reach 54 km/h. It can be said that although wheel excavator does not occupy the mainstream position in China, its technical level is not backward.

Advantages and disadvantages of wheel type excavator

Advantages: high speed and long distance autorotation, general speed up to 40-50KM/H, mobile and flexible characteristics, fast replacement of a variety of operating devices, no damage to road characteristics, suitable for hard ground construction.

Compared with the crawler hydraulic excavator, the disadvantages are: high price, low efficiency, poor stability, poor safety, poor heat resistance, inability to enter the mine or muddy areas, and poor climbing ability.

The mainstream of the wheel excavator market is 15-17 tons of products, and the small excavator market is 6-8 tons.

The main technical difference between domestic brand products and foreign brand products is the bridge box technology. The service life of domestic products is shorter than that of foreign brand products.

Wheel excavator is applicable to urban water supply, municipal, pipeline maintenance engineering, civil engineering, industrial material handling, tunnel excavation, water conservancy engineering, urban demolition, etc.

Difference between wheeled excavator and crawler excavator

It mainly depends on the occasions you use, and each has its own advantages. But now more and more people like crawler excavators. Although the mobility of the crawler excavator is poor, it is not necessary to use the wheel type of the wheel excavator for long-distance transportation. There are special transport vehicles; If the price of small wheeled excavator is walking on the construction site, the crawler excavator may be better.

Wheel - action is not as fast as track, rotation is not as large as track, wheel - is 180 degrees,<@ track rotates 360 degrees freely.

The wheel type can be used for road driving, but the track type cannot be used. The wheel type is more convenient.

But the track can work on the mountain, let alone the wheel style.

In addition, the power and trafficability of the wheel type is not as good as that of the track. The track can go up a right angle slope and is not easily restricted by the soil.
