    I am about to start building a new dump trailer and I have been looking at others designs for detail info. I have seen both the straight ram and the scissor lift styles, but no manufacturer can give me a consistent answer as to which is better. I am guessing that the Scissor (single or dual ram) is stronger as i see it more often on larger trailers (over 7K gvw), but I have seen some 21k's with straight rams as well as the 10 wheel kenworth dump i used to operate had a straight ram.

    Any opinions, is it just cost related or maybe manufacurer preference or is it based in duability?

    BTW i am making a 10K-16K range dump (not finalized on the size yet). more than likely a 9,999 to keep under class A and to avoid the $850.00 :eek1: perm plate.

    W/o knowing a lot about the sissor style I'll guess that those can use a ram that is either a shorter stroke or a smaller bore. Either would cost less. The down side is that the linkage weight eats into your net capacity and has more to maintain.

    from what i have seen the bore is a lot bigger in a scissor, but it definetly is a shorter stroke. From the best i can tell so far the scissor doesnot have to displace any of the cargo area as it folds flat under it. a large single ram (think dumptruck) has a large area in the front of the bed boxed to hold the top of the ram, reducing cargo volunme. maybe it makes for too muck toung weight too?

    I like to build things (like many others on here) and have a few successful trailers under my belt. I want to learn more about hydraulics and this is a better way than plan "b" (plan "b" is to fab my own hydro steer). If I make a few mistakes along the way i shouldn't die, so long as I keep my head out from under the box during lifting:wink1: . if all goes well I am on to steering parts. here is a picture of the last trailer I welded up (non dump). it about 2 years old in this pic and this is after i sold it to a friend. kinda crappy pic but the only one i got.

    i have had 2 yards in this of pee gravil, she dumped it no problem. pulled great. has 225/75/15 tires and brakes on both axles. back door is setup so you can wiggle it up off the hinges. and the pass side lock is just a old spring eye bolt and bushing tube cut in half and spaced out for bolt to piviot.

    How much would that 12v motor to power that ram cost? My car trailer has a dumping deck, but the ram is just plummed back into its self and acts like a big shock absorber so the thing doesn't slam up or down. Sorry for the minor hijack.
