Going to look at an old Loed telehandler, think its a 545. Center telescopic boom was "repaired" due to pin walking out of the telescoping cylinder base and catching on main boom section and bending the pin bosses. Apparently the whole area was cut out and rebuilt with mild steel and migged together. Buddy who owns the machine went over to check on the progress of the repair and saw the welds connecting the new steel to the original boom and there was tons of porosity. I'm going to take a look tomorrow- I'd assume the original material was a572 or better, any way to confirm?

Reply:it could just as easily be mild steel though; i built two sticks for another telehandler (skytrack sp) and when i put a mag drill with a cutter to it it went through like butter. i figured it was anyway since they were half inch plate. it's amazing how thin the material is on those jlg's even the 135 and 85. this is some serious guerilla fab; welded out with 211mp Attached Images |
