    So I thought, time to weigh it again. Got the weight, 3020 and it's 3500 max. Deep joy.

    Which did not last very long, I looked at the Burstner plate on the side

    1.1650
    2.1750

    Then I looked at my weights 1220, 1740.

    Well under gross weight but on these figure I can't carry anything more :(

    Looks like we've been illegal for 8 years.

    Those figures don't seem to add up if your gross weight is 3500 then the axle weights on the plate can't be correct, there is always a margin, when the two axle weights are added together the sum is always greater than the max weight on the plate.

    Your actual weighing's don't add up either, the sum of the two axles is 2960 and your quoted gross is 3020, a difference of 60k which is too much, they should be very close.

    Yes, it's gone down hill from post one. In the Burstner handbook there is an example calculation showing max weight at 3500. This idiot never twigged the Burstner plate actually said 3200. So we have 1650+1750=3400 on the plate.

    Actual weights, 60k is a fair old error, pass ! At the local waste place the girl said "printed or written" and I asked what is the difference, "£10 or free". I went for free.

    The weighing was "iffy" too. She asked me to stop with the front wheels on the bridge but because it's 4 foot up a ramp the back wheels would be a foot lower. For the back weighing the front wheels were a foot down, certainly not exactly the same as the first weigh.

    I have just asked SV Tech if fitting some form of rear spring assist would boost the back capacity.

    The plate makes sense now and the difference in heights would account for the difference in actual weights.
    Good luck with getting an uprate.

    Brian I used to own several weighbridges and all were registered as public weighbridges. You cannot get an accurate weight if the vehicle is not level if you're gonna weigh axles like that the concrete each end has to be level.

    3200 doesn't seem correct to me (but what do I know?) - even our little 5.99m low profile Chausson has a plate of 3500 max overall.

    I once had an argument with a sergeant traffic policeman about the availability of axle weighing facilities in the area that I operate a truck in. He pointed me in the direction of the corporation public weighbridge which was up a slight ramp, when I pointed out that this method was not accurate he told me that was how they did it and it was my responsibility anyway. Really helpful chappy he was.
    I had just been fined over £600 for being 11% overloaded on the front axle of a 7.5 tonner, about 40k, I moved 4 cartons from the front and it was OK. Summons said that I was grossly overloaded and dangerous this was many years ago before fixed penalty's came in and justice was meted out by magistrates who knew SFA about transport........it still rankles.

    Losing the plot Old Age Doesn't Come Alone they say.
    Used to be good at mental arithmetic :oops:
    Just rechecked the weights as 20kg on the rear didn't seem right.
    100kgs left on front
    200kgs left on rear.
    Doh :doh:

    Is there not a "margin of error" on weighbridges?
    They surely can't be 100% accurate!

    Ok I've seen your later post now and edited my response. I'm now close to max on the rear and light on the front. Something I mentioned on an uprating thread here but the gist of it was:

    The only thing I would add is the increased weight on the rear axle does lighten the traction on the front and I suspect I may have grip problems similar to my old van which had a marked difference between the two. Difficult pulling away at times, particularly hill starts in the wet. With the front axle so far forward it's not easy to shift loads to compensate.

    I only discovered this when checking the new weight with bikes and new towbar on the back but pulling away onto the main road from the weighbridge saw the front wheels searching for grip for a second or two, or was it just me being heavy on the throttle?

    rear axle limit often reached before all up weight reached, unless you have maxi chassis......... a light front axle ain't to cleaver either:(

    If a registered public weighbridge 20 kgs max error allowed over the total so must be within 2okgs over 50 tons in our case. All bridges have a zero button which allows you to reset if heavy with rain muck or snow but after so many resets (can't remember how many) bridge has to be recalibrated by engineers (expensive job) steam cleaning can often get back to a minus weight then you can reset again.
