What do the numbers stand for on excavators?

The numbers on excavators usually refer to the weight of the machine in metric tons. For example, an excavator labeled as "200" would weigh 200 metric tons. This number is important for determining the capabilities and limitations of the excavator, such as its digging depth and lifting capacity.

Here is a general breakdown of excavator weight classes:

- Mini excavators: Up to 10 metric tons

- Compact excavators: 10 to 25 metric tons

- Mid-size excavators: 25 to 50 metric tons

- Large excavators: 50 to 100 metric tons

- Ultra-large excavators: Over 100 metric tons

The weight of an excavator is not the only factor that determines its capabilities. Other important factors include the engine power, hydraulic pressure, and bucket size. However, the weight class of an excavator is a good starting point for understanding its general capabilities.
