Since the beginning of the 21st century, wheeled excavators have been coming into people's eyes. For this convenient model that walks on tires, some people want to comprehensively compare which model can bring a higher return on investment, but what this page wants to say is: each has its own advantages and disadvantages. Meeting the market demand and bringing a higher return on investment is the last word.
First of all, wheeled excavators are easy to transfer. They mainly do some small and medium-sized projects in cities or rural areas, most of which are municipal projects. In places that are too soft, most brand wheeled excavators can not fully cope with them. Wheeled excavators can do simple jobs easily, and will not damage the ground in cement land, lawn and other places, However, the crawler excavator will make a mess of the ground, but the application field is not as extensive as the crawler model. Of course, the crawler excavator can't drive on the road, but it can work in a muddy place without sinking.
In terms of appearance, crawler excavators are obviously different from wheeled excavators. Generally, the individual and self weight are large, and the efficiency is relatively high. In addition, because crawlers are metal products, they can be competent in mines or places with poor working conditions, and have stronger off-road ability. Their disadvantage is that compared with wheeled excavators, they have large investment and poor mobility, The higher design speed is only 5 ~ 7km / h, and the long-distance movement still depends on the trailer.
Why are wheeled excavators more and more popular in the market? On the one hand, the reason is that the investment is small and the action speed is fast, and the general speed can reach 40 ~ 50km / h. on the other hand, it is strongly promoted by the national policies on new rural construction and the construction of township and urban ancillary facilities. The demand for wheeled excavators is becoming more and more extensive. In addition, the multifunctional use of wheeled excavators is no less than that of Crawler excavators, A variety of accessories can also be used freely. The installation of crushing hammer, rotary drilling rig and vibratory rammer on wheel excavator also has some special uses, and the economic benefits are considerable.
