Question: Which factor has the MOST significant impact on an excavator's stability when digging over the side of its tracks?
Answer options:
- The condition of the excavator's paintwork.
- The amount of fine material in the excavated soil. ✅ The extension of the boom, dipper stick, and the weight of material in the bucket.
- The ambient air temperature during operation.
Correct answer: The extension of the boom, dipper stick, and the weight of material in the bucket.
