Wheeled excavator, different from crawler excavator, is an excavating machine with tires as the walking parts, which has the characteristics of moving flexibly and not destroying the road surface. It specializes in medium and long-distance transit operations, can be equipped with multifunctional attachments, and is compatible with crawler excavators. Because of these characteristics, it is widely used in the fields of municipal engineering, landscaping, farmland water conservancy, construction engineering, forestry and animal husbandry.

As early as after World War II, before the birth of hydraulic excavators, wheeled excavators first appeared in Europe, which were mainly used to operate on city streets. Until now, Europe is still the largest production and sales market of wheeled excavators. At that time, wheeled excavators used a lot of technology and off-the-shelf components from trucks, such as drive axles, steering drive axles, transmissions, braking systems, etc., and usually used a 4X4 drive format.

Early mechanical wheeled excavators
In the early days of hydraulic excavators, manufacturers also used wheeled chassis, with the 3-wheeled form being more common. Soon, drive axle swing technology appeared, allowing one drive axle to swing at a certain angle in the lateral direction, allowing all 4 wheels to land on uneven ground, and the 3-wheeled form was soon eliminated. Since then wheeled excavators and tracked excavators have gone hand in hand while continuing to evolve.
Developing to 2016, China's wheeled excavator market has ushered in a new change. In the past, the wheeled excavator market focused on the municipal field in the city and the infrastructure in the suburbs, and the market demand was not high compared to crawler excavators. However, with the accelerating urbanization and new rural construction in China, the development trend of replacing manpower with equipment is becoming more and more prominent. The above projects are mainly small-scale short-term projects with a wide range and a single project volume, and most of the projects are localized and multi-location in nature. Flexible, convenient transfer wheeled excavator with its unique advantages to win the favor of the market. Compared with crawler excavators, wheeled excavators have more significant advantages in terms of multi-purpose. Many in the crawler excavator on the use of infrequent generics, can be in the wheeled excavator to play the most extreme utility, which makes the already flexible small wheeled digging is like a tiger to add wings, will be excavating machinery to expand the horizontal field to the history of a new height. Whether it is road crushing, pipeline laying, or house demolition and construction, green belt rest, it can flexibly cope with. Even timber, waste, cotton, sugar cane and other loading and unloading areas can also play its performance advantages, especially in the field of timber loading and unloading, breaking the previous crane, loader and other machinery and equipment, low efficiency, high expenditure dilemma, can be described as the loading and unloading industry mechanization of a change.
On the other hand, along with the rise of various types of wheeled excavators, major leading domestic construction machinery enterprises have entered the wheeled excavator market segments, accelerating the promotion of the wheeled excavator industry standardization, standardization of development, but also led to the continuous innovation of the industry's technology, wheeled excavator industry ushered in the spring.
