    Default Towing with a CX

    Hi,

    Looking at doing some towing with the CX when back together (pic shows current towbar)

    The trailer frame will be 10 x 5. Wheels outside frame. The body on the body of the trailer will be solid about 4ft high - camper trailer style. Should weigh about 500kg all up.

    Now, not having done much towing other than a box trailer, I was wondering what type of suspension i should get on the trailer so it is best suited for the CX. Would it be different behind the C5 X7.

    Does the extra foot of width make much difference when towing? I am thinking the CX is about 5ft wide, rear vision should still be good without the need to add bigger/wider side mirrors. Any wider might be different though.

    advice from you e pertinence towers would be welcome?

    best to put the axel 200mm back from the centre of the trailer makes it tow very well

    As long as you have adequate nose weight (about 10% apparently is best) the CX will effortlessly haul anything you care to string to the back of it

    Hi
    This might be OK but really it is just necessary to get the balance right(loaded), and end up with "adequate nose weight (about 10% apparently is best) the CX will effortlessly haul anything you care to string to the back of it " as Shane says. Heavy things in the middle.

    500 Kg is just a lightly filled box trailer My suggstion for a suspension is any normal type. Being a bit fancy is really wasting your time. One that does not bump steer too much is always good for tracking well.

    With the nose weight you are saying that if your trailer weight is 750Kg then you should have 75Kg on the ball. Is that correct?

    I have had a salesman tell me that the torsion axles are better than the sprung setups. I have no experience with the torsion axles - I can see they look neater but as far as towing goes not sure. The trailer I am looking at is a single axle 9x5.

    If it's a standard box trailer .... IMO simple is best. Light truck tyres are a necessity IMO ... 9 x 5's tend to get overloaded. If it's not going to be twin axle.... Put the highest rated springs ( eg: 7 leaf 1.5 ton springs/axle under it). Trust me ... It WILL get overloaded to buggery at some point. I prefer brakes on anything over 6 x 4 too.

    This would be my list:
    --1.5ton axle ... leaf spring would be fine
    --over-ride brakes ... drum, disk... couldn't care, so long as they work.
    --high sides
    --long box section drawbar.... Drawbar continue under the floor of the trailer as far back as possible (the nicest made trailers have drawbars that go back to the spring hangers).
    --small lift off cage (very useful)
    --box section frame under the floor (look under the trailer, not what it looks like from above).
    --most box trailers will have the axle slightly back from center ... this is perfect as you will be the one loading it and responsible for weight distribution. If your fitting water tanks etc.... carefully place them.... you don't want a heavy tank of water at the back of the trailer.
    --quality LED lighting ... if you can't see it when the sun is out, it's no bloody good

    I used to think galavanised was a good idea. However any solid metal I figure is fine for the box of the trailer. Your going to be painting it nearly every year if you use it either way (as you scrape the paint off with shovels etc...).

    You can pick the good trailers within about 30seconds just by looking under/over them.

    I'd add the use of dampers. BF wagon units are as compact as you will get for a leaf spring set up. If someone says slipper springs are OK then turn around and start walking, slipper springs basically grind away at the trailer chassis (not the smartest system and still legal!)

    All my trailers are slipper springs ..... Never had a problem. I just fitted new 7leaf 1.5ton slippers.

    I agree if it's going to be a twin. You'd rather a load sharing setup for twin axles. Having said that, my car trailer is twin slipper axles.... It's one of the nicest trailers I've towed......

    The problem I see with slipper springs in this instance is..... take a speed hump for example. I pull the loaded car trailer up onto the speed hump. The front axle will be carrying nearly the full trailers mass as the front axle rolls up onto the speed hump. Then as I pull it off the speed hump, the rear axle is carrying nearly the full weight (so over 2tons on one little axle). Seems to work well though So it's got me buggered.

    I doubt most of us would wear out a slipper spring in 3lifetimes
