    What's the best way of finding axle weights? Can any weigh bridge do this or does it need to be a special one to determine individual axle weights?

    I thought it would be as easy as driving part way on, then fully , then part way off and checking that the sum of the first and last reading equals the overall weight but a local (non public) weigh bridge said this wouldn't work.

    any weigh bridge will give overall weight and individual axle weights. just ask for the printout

    Um, I know of at least one that won't!

    How do these other weighbridges work? Do they have separate weighing sections for each axle or us there a special procedure?

    If the weighbridge is set level with the ground there should be no problem with weighing individual axles and checking with total weight. Errors can arise when the bridge is raised up and access is via a ramp.

    p

    That was the case with the one I was at today. I could see how that might throw things off.

    Is the procedure as I described in my first message then?

    Most weighbridges operated by VOSA are dynamic axle bridges where you drive very slowly over a narrow plate. These are the recognised accurate way to check axle weights but VOSA and the police will use plate weighbridges when necessary.

    The method you suggest is correct but some weighbridge operators might charge you for three separate weighings, best to check first.

    Mine does 2 weights on one ticket, I did the two axles individually but wanted an overall weight so it meant a second printout. Charged me £10 altogether but that was 2 years ago when I wanted it for tyre pressures and peace of mind. :Smile:

    Vosa and trading standards work together and have Axel weigh plates known as dynamic bridges we have one at gildersome Leeds owned and operated by trading standards it is 24 hours I usually nip up after 6 pm when they all gone and do it my self simple to use
    Drive up to lights wait for green light drive as slow as possible over plate a display gives you axel weight then when last axel passes gives total make sure you have pen and paper no print out

    I believe most counties have some thing similar
    Check vosa site and trading standards for info

    I did mine last week at the local MOT station. The weights are determined on the rolling road used for brake testing. Just drive on, stop and take first weight, drive on again to locate rear axle and take the second weight. The tester didn't even charge me!

    Needed the weights to work out tyre pressures, discovered my van was 110kg. overweight so I've been clearing junk out this past few days.

    Just weigh the front or rear axle then put the whole motorhome on and you will have the 3 weights you require for 2 weighing s, Simples!

    Handy if you have an in ground weighbridge, our nearest is 50 miles away so MOT stations are handy.

    Most council tips have a weighbridge. They normally only charge if you want a printout, but ours does not if you are willing to accept a written one instead. - and yes that is for axle and gross weight.

    I went to our local scrapyard - sorry motor salvage company - who did front axle, rear axle and then total separately. Three nice tickets all showing good numbers. He actually apologised from behind his barred and bolted office window for all the low life hanging around as well. Cost me a tenner and money very well spent.:thumb:
