The travelling speed of cranes varies from_________________?
Correct answer: D. 1 to 2.5 m/sCompare Power Rates
- A. 20 to 30 m/s
- B. 10 to 15 m/s
- C. 5 to 10 m/s
- D. 1 to 2.5 m/sCompare Power Rates
Explanation
Crane travelling mechanisms normally move at about 1 to 2.5 m/s, allowing controlled positioning of suspended loads. The other ranges are unusually high for crane travel.
