The length of the boom and arm is the main distinction between long-reach excavators and conventional excavators.

The main differences are as follows:

1. Boom and Arm Length
2. Project Types
3. Reach and Depth
4. Stability Considerations

In conclusion, the boom and arm length are the main distinctions between long reach excavators and standard excavators. Standard excavators are adaptable and used for a variety of construction and excavation tasks, whereas long-range excavations are specialized machines made for particular applications that require extended reach.
