The crane rated at 20000k falls into which category?

• A. Category 1
• B. Category 2
• C. Category 3
• D. Category 4

Answer: (C)

Categorizing crane capacity into bands helps match lifting practices to the machine’s strength and required safety controls. A rating of 20,000 kilograms sits in the mid-range of those bands, which in this standard is Category 3. That category is designed for tens-of-tons range, smaller than the heavy end but larger than the light end. So a 20-ton crane isn’t light enough for Category 1 or 2, and it isn’t at the heaviest end that would push into Category 4. Always check the exact threshold values for Category 3 in your specific standard, but the idea is that a 20-ton capacity aligns with the mid-range category.
