Hello all, we have a 14 ton flat bed rigid and we need to tow a trailor. What weight are you allow to tow and does the trailor need air brakes, is there any regulation for axles etc
Probably on the wrong forum.
Your truck will have a max train weight on the plating certificate. This will tell you what you are allowed to tow. The trailer you use will have its own plate with axle limits. There are certain requirements as to brakes with trailers but I don’t know what they are off top of my head.
What type of trailer are you thinking of towing? Are you talking about they type of trailer you could tow with a car or is it a large drawbar type trailer?

The driver would need a C+E if the trailer is over 750 kgs plated MAM
If the trailer is between 750 kgs and 3500 kgs plated MAM then it needs over-run brakes
If the trailer is over 3500 kgs plated MAM then it will need air brakes
Find the VOSA weight plate on the lorry - it will have 4 figures on it
Top figure is the GVW which should be 14000 in this case
The next 3 figures I will make up …
Second figure is the GTW = 24000 - that is the max both lorry and trailer can weigh together (actual weight not plated weight totals)
Third is front axle = 6250
Fourth is rear axle = 8250
Axles always add up to more than GVW to allow for some flexibility when loading
Lets say you now get an air braked trailer with a plated MAM of 15000 and 2 axles plated at 80000 each
Again - the axles add up to more than the MAM to allow for load placing flexibility
Empty lorry weighs 6000 so has a max payload of 8000
Empty trailer weighs 5000 so has a max payload of 10000
You now have a total empty weight of 11000
GTW 2400 minus empty weight 11000 = max payload of 13000
You now need to load 13000 so you could do this … examples
Load lorry with 8000 and trailer with 5000 (lorry now 14000 + trailer 10000)
Load lorry with 6000 and trailer with 7000 (lorry now 12000 + trailer 12000)
Load lorry with 3000 and trailer with 1000 (lorry now 9000 + trailer 15000 = DEFFO NOT RECOMMENDED)

what about the tipper boys who pull road planers around with empty trucks

Not saying it cannot be done legally just that its likely to get the - tail wagging the dog
thanks Mick, no decision yet on trailer but looking something to take 8 bags of fertiliser weighing 600 kg’s each.
