Need to adjust parking brake on Cat truck pictured, weighs 13,000 lbs. Manual has good step-by-step with photos for brake adjustment, but one small detail isn’t mentioned, namely fact that all doodads to be removed, tweaked, replaced are only accessible from underneath truck. I’m sure the Cat folks just drove over a pit to get the pix but our landlord would be hesitant regarding me constructing such a pit in his floor, I suspect. So I plan to lift front of truck somehow and set front wheels on solid blocks after rear wheels securely chocked, all on level surface of course. Lifting whole truck level would give better access but much harder for us to do, so plan is to lift front only.
My question: Since it would be much easier to lift front by raising end of forks with smaller forklift (6000 lb cap.) I’d like to do that if it won’t damage forks or mast on Cat. This lift point shown as “B” in pic. See, what I don’t know is whether fork connection to mast and mast connection to truck are both designed so that forces applied in direction opposite to those for which they were designed, are acceptable.
Method “A” (much harder to do) uses pair of cable reel jacks astride load, lifting 2.5” solid steel shaft chained on both sides to the square lifting eyes, max 10” lift before blocking, re-rigging needed.
Method “C” would involve setting very strong machine bases on lower side of loading dock and driving Cat off dock a few feet so each wheel supported by separate machinery foundation. This would probably be the easiest and give by far the best access but is obviously a bit scary if only due to the large amount of potential energy involved, and thus I’ve been scared away from it.
So, ok to lift ends of these 6’ forks, or not? Also if you’ve had occasion to elevate a heavy vehicle to work under it, how did you do it?
