portable hoist frames
what level of stress do some of you allow in order to certify an a-frame type (usually on casters) hoist frame?
find a job or post a job opening
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.
