Small excavators, also known as small excavators, have different definitions. For example, in countries where excavators and loaders are popular (such as Britain, France and Italy), 1-3 ton small excavators are the mainstream. In countries where backhoe loaders are not widely used (such as Germany), 4-6 ton products are preferred. However, almost all countries tend to buy larger equipment. Therefore, we come to the conclusion that the definition of small excavators is that excavators and loaders of 1 ~ 6 tons are called small excavators, of which products of 2.7 ~ 3.0 tons account for a large proportion. The reason is that they can easily use general transportation vehicles for site transfer. Thanks to its small size, small excavators have mainly become ideal equipment for earthwork applications in urban areas.
