  • Heavy Haul Trailer

    One of my customers called this mourning,their heavy haul truck took out part of a rail road crossing! Truck loaded with a cat345 trackhoe,boom laid down in between the main center beams of the trailer,well when he caught the track doing 30 mph it stopped the truck almost in its tracks.Well the backhoe slid forward on the trailer ended up on top of 5th wheel,never slid off,but the boom took out 5 crossmembers between the main beams.Need to replace the bent crossmembers,This is probably t-100 steel the main beams
    I'm thinking cut out old ones ,preheat main beams and weld back new rectangle tubing 6x12x 1/4 wall back in with 7018. Anybody out there have any experience with these heavy haul trailers?

    I can't tell you how to fix it but I'd like to see a pic or two of the situation.

        Actually i missed all the fun,they had the trailer at their shop this mourning. One of the mechanics said everybody (law&railroad people)was on the scene .Good part no other vehicles were involved, the driver was shook up a bit from the sudden stop ,couple cuts on the head from the steering wheel and fortunately it was around 7:00 a.m. in the mourning hardly no traffic on sunday mourning.

          I checked my charts, unless I over looked it, I cannot find “T-100”! Is this some type of T-1 that I’m not familiar with?

              There are a couple of guys over on the shopfloortalk.com board who repair this kind of stuff regularly, and seem to do a real good job of it, you might post over there too.

                Most likely T-1.

                I worked on some heavy haul lowboys that were made with T-1. These trailers were grossly over loaded, and abused! Cracked welds from one end to the other. We arced the bad welds out, and re-welded with 110-18. Everything went according to plan, until the post weld cool down!

                  Hey sonora are you refering to the steel cracking along the outside of the new welds?

                      T-1, T-100, QT (Quenched and Tempered) 100 ... Same - Same just different terminology depending on what your local steel shop calls it.

                      Main rails should be QT-100.

                      Cross members will be "Mild" Steel, and should be "Wide Flange" available at just about any steel supplier.

                      I pre-heat rails, then weld out with Hobart Fabco110 (Dual Shield Flux Core) or with 110-18 to match the characteristics of the stronger of the 2 metals, which is the QT-100.

                      Other than the way the damage was caused, it is a pretty common, and straight forward repair.

                      Have a Good Night.

                        Hello shade. Do you have any picture? I think your trailers were grossly over loaded, and abused. Trailers are known to have the capacity to easily carry a heavy or any other vehicle.

                              Heavy Haul Trailer

                              This discussion makes me recall my high school days forty years ago growing up on a cotton farm.

                              We ran John Deere row crop tricycle tractors, mainly 70, 720 & 730's. The front wheel forks were subjected to a lot of abuse and tended to crack between the four 1/2" bolt holes where the fork was attached to the bottom of the steering sector shaft.

                              I think these forks were made with the T1 steel being discussed.

                              The repair that worked or took the longest to break again was to drill the crack ends, grind out the cracks and heat the bolt hole area as best we could with a multi tip rosette oxy-acetylene torch and weld with a "low hydrogen" rod. E-?????.

                              My question is what is / was this LH rod, what is its classification code and would it be useful for this type of repair of T1?
