Safety Factor
(OP)
Can someone tell me the saftey factor for a lift truck. Like a special fork lift. no one will be under it. It has to lift 8000lb, flip it then bring back down.

RE: Safety Factor
My recommendation for accurate info, if you are looking to buy or rent, is to contact a reputable vendor. It sounds like the lift you either have or require must have special characteristics to allow it to flip a load. I would definitely contact an EXPERT.
Good Luck,

RE: Safety Factor
ex. the fork stresses and strains analysed might yeild a safety factor of say "4" to lift say 1000lbs and I lable it "Max Capacity 1000lbs". Is that safe enough or is it insufficient. What is the standard and or does anyone know where I can find that for a fork lift or something similar.

I've done gibbs and alternate cranes to 2 1/2, but had absolute certainty with MTRs and craftsmanship, merchantability issues.
Your call, but at least you have an ball park estimate.

RE: Safety Factor
The fork lift you are considering is a very specialized lift and you will be hard pressed to find a local representative well versed in fork lifts of this size and type. Moving a load of that magnitude after lifting as mentioned in previous post is all about the important CG as well as few other things that hold the load.
I've been involved in investigations of serious accidents with Fork Trucks that had serious injuries. Two accidents were prior to OSHA and the last one was with OSHA, they were not much fun to work with. They were right so there was no argument, the fork truck had an unauthorized modification.
I would at the fork lifts used in the metals industry.
RE: Safety Factor
Of course the chain pull should be calculated under a jam/stall condition and "E-Stop" and not by weight of load under normal conditions.
How much safety factor you need is mostly determined by how much damage/liabilty might be incurred if there is a failure.
