I understand the liability issue with welding on new brackets on the back of forklift fork but I'm just curious if anyone has done it?I know forks aren't that hard so I'm not seeing an issue with welding on them. I figure just use some 8018, maybe throw a little preheat on them, stress relieve with a needle scaler just to be safe. This is my own forklift and I will be the ONLY person using it.Thanks for any input!-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe
Reply:Be careful doing this! Most likely the forks are T-1. Years ago, we use to cut holes in the tips of the forks, for shackles to go in. OSHA put a stop to that! Any fork with a hole in it had to be replaced.Dont pay any attention to meIm just a hobbyist!

Reply:Yeah I've drilled holes in them many times! It's just so handy having holes in the tips of them!That's what I figured, they'd be a T-1 type material, in which case an 8018 or 80s wire would be a little low for tensile strength. I'd probably be best off getting some 11018 then.-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe

Also be careful with disrupting the weight distribution of the forklift. If you increase the lifting distance from the mast you may either cause premature failure of the hydraulic components due to a couple that is beyond design tolerance. As long as you know the risks then go ahead. Just make sure it's hidden in the back when the clipboard warrior comes along. Sent from my SM-N920V using Tapatalk
Reply:I was on a bridge job one time. We had a CAT 988 loader with forks. Some how the operator broke one of the forks right at the heal
. I got elected to weld it up. The fork was 8-inches wide, and 4-inches thick at the heal. I double beveled the long side of the fork. Preheated the fork, and used 5/32 7018 to weld it up. Wrapped the fork in insulation, for a slow cool down over night. I was on the job for another year, the fork never broke again in that year.Dont pay any attention to meIm just a hobbyist!

Reply:Whenever I think of welding big mass stuff like that I think of all the stresses it will suffer as it cools. I'd think preheat. As much as recommended if you can learn the composition of steel. If I knew nothing else, I'd shoot for 600 F with a big weed burner torch. Then I'd keep it very hot by re applying the big torch as needed. I'd want the area all around the weld hot for six inches or more. Then I'd want a low hydrogen process with all the ductility I can get. 110,000 tensile strength is useless if it cracks where it joins the steel.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
Reply:abpout 25 years ago the neighbor who was in the logging busness brought 2 forks broke off about halfway up the back, he asked me to weld em back together and weld new eyes to slide over the bar on the loader I was also asked to weld onto the loader... big loader a 988 Cat.These forks were biguns, the bottom was about 10 feet long and they were about 10 inches wide maybe more, and about 4 inches thick where they were broke, he bought these things at a sale. I couldnt find anything but 1/8 and 5/32 7018, so that's what I used. I veed em out tacked em together a nd preheated em til the spit sizzled and boiled off, and commenced welding. made a nice jig with dogs to hold it all in place. 4 1/2 maybe 5 hours later I was done welding the forks, threw a blanket over it to keep it warm. then welded the eyes on the loader, these were made out of 4 inch heavy wall pipe and welded one on top of each fork to match. About a month or so later I built a thumb he wraps around the logs to clamp to the forks, damn thing probly weighs 400 lbs if not more. He did the hydraulics for it. This guy is still using the same setup today and ive seen him carry some stacks of big logs with it, scares me sometimes what he does with this stuff but he has never been hurt and he is 73 years old and still going strong.
Reply:Of course, I have drilled holes in them many times! Except that the last time I disturbed the weight distribution of the forklift. Increasing the lift distance from the mast could lead to premature failure of the hydraulic components due to the pair exceeding the calculated tolerances. I was warned to make sure it was hidden in the back. But I'm a jack of all trades; I didn't listen to anyone and did as I pleased. I had to take it to a shop nearby https://anguslifttrucks.co.uk/forklift-sales-uk/ . They told me to update it because my truck is pretty old, but I do not have money for a new one. When I get it together, I will update the loader!
