Hi all:
I've been working on this for few hours, and I've given up. I'm hoping that you can help!
I've included a diagram of what I have to work with. Basically it's an existing engine crane with a modified base that I'm trying to design it to pick up a 600-700# electric motor, (but a 1000# limit is what I'd like to design to). But I can't determine the loads on the 4 castors, in order to purchase a strong enough pnuematic castor.
I think that a 12" castor rated at 450#/caster should be more than sufficient, but I'd like to go to an 8" castor rated at 300#/castor if I can.
Because I'm only a first year engineer, and only have basic statics under my belt, I'm really confused trying to solve this one. Can anyone help and show me how to calculate this?
Thanks a bunch,
Shaun
