Hi guys.
I've been working on a design for overhead cranes, and I have some questions about side thrust forces:
1. Why does a radio-controlled crane produce two times bigger side thrust forces compared to a pendant-controlled crane?
2. For calculating side thrust forces, there are two approaches:
1. Based on AISC, you simply consider it as 20% of (lifted load + Trolley Weight)
2. Based on other references like CISC and AIST, you should consider the greater of:
1. A percentage of lifted load given in tables based on crane type
2. 20% of (lifted load and trolley)
3. 10% of (lifted load and crane weight)
In some cases, the second approach results in much bigger loads, so what should we do? stick to AISC or use the bigger values?
