Hi guys, i am familiar with FEM standard about Crane duty group which is 1Bm, 1Am, 2m, 3m, 4m but not sure about other standards such as ISO, ASTM... Does anyone has a good experience in choosing correct working group of a crane? Normally, we only know following information: - Lifting capacity - Lifting height (or hook path) - Crane span - Number of operation time per day. Question 1: What is equivalent duty group with FEM? Question 2: How to determine correct crane working group? Hope you get your ideas on this issue. Nice day!
Hi there, Take a look at the FEM to ISO Classification below: 1Dm - M1 1Cm - M2 1Bm - M3 1Am - M4 2m - M5 3m - M6 4m - M7 5m - M8 Hopefully this information is helpful. __________ -Jose http://www.munckcranes.com.mx
