My forklift flat boom was made many years ago from scrap just laying around it has served us well but I always knew there would come a day when the beam on it would fail due to the lack of bracing and it being undersized. A while back I picked up something that was really too heavy for it and I noticed it flexing. I should have done some beefing to it then but I had finished the job then forgot about it.
Today Karma bit me LOL. I picked up a Miller Big 40 welding machine with it Not half as heavy as what I had used it for a few months ago but today I managed to get it in a sideways bind and it cratered fortunately nothing else was damaged
Time to beef it up with a much stronger beam
the old beam was W8x10 with a section modulus of only 7.81 with a 30.8 moment of inertia
the new beam is w8x24 section modulus 24.3 moment of inertia 98.0
making the new beam ( also from my scrap pile) more than 3 times as strong as the old one
