        I used to like putting on hitches as i did hundreds of them. My grand dad was an early pioneer of the truck hitch back when you couldn't run and buy one off the shelf....Bob

          Bob, thanks for sharing your history... that's pretty cool stuff. I like the drawings.

            Very nice work. I like it.

            The ones that I have built up here are much the same, with a couple of extra steps - Everything built for the oilpatch, construction, or forestry.

            On the winch tractor tow aprons, we run 3/4" plate for the apron, then wrap the lower edge and sides with flat bar. Anything from 3/4" x 4" to 1" x 3" depending on customer.

            Gravel truck and log truck tow aprons same thing. Depending on who you work for, and their particular "spec".... I have seen the apron wraps as deep as 4" around the bottom edge, and 6" to 12" deep at the top where it attaches to main frame.

            Winch tractor aprons are welded to the ramp/roll assembley then bolted on. Some weld them to the frame, but I don't - They are a nightmare to repair.

            Gravel truck and log truck aprons are usually part of a removable frame insert.

            I see that your pintle hitch is quite high, so the reinforcement that I do here is unneccessary in your application.

            You ever use the pintle hitch with the air-activated slack compensator??? A little extra work but the end product is nice to tow with - No hammering.

            Don't mind me, I'm rambling tonight.

            Nice work. Keep it up.

            Gotta love Mag Drills.

              I haven't used a mag drill in years and Black Wolf is right you gotta love em!!!
              Great job on the hitch!

                I have not used a air slack hitch but have installed 40ton ring with a heavyduty spring built on the back side to absorb shock.These usally go in 10whlr or tri-axle applications and those run with 1"or 3/4" plate.Also thanks for the compliments guys.Just another day here at shop.

                      Great work! I have to fab and install one on my dad's Ford L8000 dump. I'm not quite sure how thick is apropriate though. Anyone have any suggestions? I'm not quite sure just what factors I need to consider in the design process But I have a general Idea of what to do.

                        nice looking thanks for the pics.
                        We have all 15 and 25 ton pintle hooks with spring cushion where I work. Pretty tough, but they do work on them as some trucks pull a trailer almost everyday.
                        Good job

Any thinner than 3/4-inch plate and I would be thinking on the lines of a * pattern. A truck that size I would go with 3/4-inch plate, and still weld strong backs on the backside. Could also look at welding or bolting a diagonal brace from the backside of the pintle hitch back to a cross member in the truck frame. Or go with a < shape and bolt into the truck frame in two places.
                          If you donít have a proven design it is easier to over do it at first, than repair it later!
                          Thanks for the advice! My dad has a general idea of how to do it but there's some key strength requirements that he dosn't know how to design. I'll ask him what his load requirements are to get a better idea.

                            He said he would like to set it up for a 30 Ton trailer. I'm thinking 7/8" plate would work well but I'm not quite sure.

                              7/8" would be fine for 30 ton.Just add gussets add weld it up good.Good luck
