Why do 5er's use 5th wheel hookups and cargo trailer use gooseneck hookups ? I have seen gooseneck balls that are concealed in the floor so you can use the bed of the truck without removing a big heavy 5th wheel hitch, so I can understand that part.

For the same reason that OTR trailers use Fifth-Wheel hitches: more secure and easier to hitch up. Heavy equipment is towed using either Pintle or Gooseneck hitches due to the frequent need to traverse uneven ground and/or ditches. >"JerryD\(upstateNY\)" <jerry@righthere.com> wrote in >news:hWCkg.45850$8G3.21431@twister.nyroc.rr.com: [quoted text clipped - 6 lines] >For the same reason that OTR trailers use Fifth-Wheel hitches: more secure >and easier to hitch up. It also has a much larger surface are to transfer weight load to tractor so that the "pin" only sees the pulling loads and nothing more. >Heavy equipment is towed using either Pintle or Gooseneck hitches due to the >frequent need to traverse uneven ground and/or ditches. Likely true but also because heavy equipment is most often towed behind dump trucks it a tractor trailer in not used and a pintle is well suited to this while also yeilding the strongest trailer with lessor amont of materials. (it can weigh less carring the same load) yeilding a higherpotenail payload at same GCVW. I towed heavy equip behing dump truck in late 70's on "floats" as we called them and I can tell you first hand that they tow well behind a dump truck, even behind a good sturdy single axle dump. You need to get about 15% or weight on pintle though so if trailer is 30K you need at least 4500 lbs on it to tow well stabilty wise as 4500 lbs is nothing for a good dump truck. ----------------- The SnoMan www.thesnoman.com > > [quoted text clipped - 39 lines] >www.thesnoman.com > Snow man, and I have not expressed this on this ng before, YOU ARE FULL OF sh.t, comming from a retired superintendent of transportation.

What >did you pull your back hoe to the septic tank job. The only one here full is you. I have been there and done it and haled backhoe many miles on floats behind dumps in years past. My guess that though you are or claim to have been a supervisor you lack real field experiance from ground up. I am not discounting tractor trailr for some applications but you do not need one to effectivly get a 8 or 10 ton backhoe or dozer to a site when a dump truck with a flaot will work nicely. You way to work the job requires a driver for semi, and one for dump truck to get a backhoe on the job while my way does not and I guess the power companies around here are full of "S" to because they haul big backhoe all over creation here on job behind dump trucks or their 2 ton untily bed truck and city does to. No sir the only one here full of it is you because just because you "were" a super does not really nean you knew anything because I have seen a lot of supers in a lot of trades that were clueless and got their job by politics not skill and you comments tned to suggest yours was not by skill. ----------------- The SnoMan www.thesnoman.com I see where SnoMan <admin@snoman.com> contributed concerning bad advice from William Boyd: > No sir the only one >here full of it is you because just because you "were" a super does >not really nean you knew anything because I have seen a lot of supers >in a lot of trades that were clueless and got their job by politics >not skill and you comments tned to suggest yours was not by skill. Boyd brainless has established a well-deserved reputation for making stupid and/or dead wrong statements & recommendations, so it is no surprise that he knows little or nothing about the relative merits of gooseneck, pintle, and flat plate towing setups. Thanks for taking the trouble to challenge his ignorant advice. Will Sill Don't worry about what people think, they don't do it very often. >I see where SnoMan <admin@snoman.com> contributed concerning bad >advice from William Boyd: [quoted text clipped - 18 lines] >very often. > I believe the question to confirm what I stated, that you haul a backhoe , and yes a small dozer behind a dump truck. I agree, but that is not a heavy load and a pintle on a dump truck at the largest is not rated for a true heavy load. I am talking about a real heavy load, it is not done with a dump truck. As for the pintle hitch, yes they have some very heavy duty. http://www.steelsoldiers.com/mk16.htm http://www.argeetrans.com/ http://www.vandykebros.com/ SignatureBILL P.

The flat plate thing is the standard on rv trailers but IMO there is no good reason for it. Some people might be much happier with a ball hitch (AKA gooseneck hitch) like those used by cattlemen. In view of recent reports suggesting that some RVfifth-wheel frames are so fragile they won't tolerate the rougher ride of MD trucks, I can no longer recommend conversion of rv trailers to gooseneck unless you are confident of frame strength, but if you are. . . . Though I made my own adapter, they are available. I suggest you use was a folding ball mount that in a few seconds can be tilted down into the truck bed, leaving it fully clear for cargo. Advantages include: Automatic compensation for off-level hookup, and no twisting strain on uneven ground. Easier no-crash hookup -just back the ball under the hitch and lower the trailer onto it. A completely clear truck bed when not using the hitch. Much less costly (hitch is a hundred bucks or less) and lighter Eliminates sensation of looseness when stopping/starting with some hitches. Stronger hitch (25,000# rating). Lower hitch point means less overturning moment on the truck in turns. Disadvantages: Requires a large hole in the truck bed Takes a few seconds more to hitch unless you have fast power landing gear. I'm not aware of manufacturers offering this option on new trailers. It worked great for me. Will Sill "A great many people think they are thinking when they are merely rearranging their prejudices."

But with the goose neck you have a relatively long leverage between the pin and the ball that stresses the frame when pulled. The trailer manufacturer would have to approve one before I used it. http://www.go-rv.com/coast/do/catalog/page?index=A&pageNext=TRUE&dealerId=7&page Num=515 SignatureBILL P. Just Me & DOG |
