Just a quick weight question really.
We run a couple of 6 wheeler transporters with tag axles grossing at 26t.
We also run 8 wheeler hookloaders grossing 32t.
I’ve seen 6 wheeler tippers and curtainsiders with fixed twin wheel axles which just got me wondering what they can normally carry, i’m sure they wont go 32t but must take more than 26t surely ?
26 t thats it
in the past some lift axle 6 wheeler’s were just short of the 26 t

Correct. My FM9 mid-lift is, for some perverse reason, 25.7T GVW.
Payload on mine, with crane on the back is about 13t.
Max gvw for 3 axle rigid is 26t. I had a stretch tag axle 6 wheeler also plated for 25.7t
The max gross weight for the three axles class is 26t, but whether a three axle truck can gross 26t depends on the design weight of the axles and their spacings. Single tyres on an axle are generally rated at 7.5 tonne, super single steer 9 tonne (with an axle is rated to carry that), twin wheeled axles 10.5 tonnes, so
7.5 + 10.5 + 7.5 = 25.5
9.0 + 10.5 + 7.5 = 27
7.5 + 10.5 + 10.5 = 28.5
9.0 + 10.5 + 10.5 = 30.0
The first truck has two disadvantages, it will never be able to make full use of the 26t class weight, and care will need to be taken to avoid axle overload when loading to the limit. Trucks 2, 3 & 4 have a design weight greater than 26t with the luxury of more leeway over axle loadings.
In the UK the maximum rigid gross weights are as follows.
2 axles = 18000kg
3 axles = 26000kg
4 axles = 32000kg
However all these weights must be checked against the plating certificate to check what the particular vehicle can weigh, including driver, fuel and load.
