What is 300 in 300 series excavator or 200 in 200 series excavator?

In the context of excavators, the number in the series designation, such as "300" in a 300 series excavator or "200" in a 200 series excavator, typically indicates the size and model range of the machine. Higher numbers generally represent larger machines with increased capabilities, such as greater lifting capacity and digging depth. For example, a 300 series excavator is generally larger and more powerful than a 200 series, making it suitable for heavier and more demanding tasks. These series numbers help operators quickly identify the excavator's intended use and size category.
