(OP)
What level of stress do some of you allow in order to certify an A-frame type (usually on casters) hoist frame?

RE: portable hoist frames

I have used the following:

Fu/5 for tension

The lesser of Fu/5 or the stress calculoated for buckling for compression

Fu/5 for connection detail design

(Fu/5)/(squareroot3) for shear.
