Spot on I just wasn't going to write that muchAll comes down to what is allowed were it works. Different size trains allowed in different parts. Rough guild is steer axel allowed 6t, a bogie group 16t and tri group 20.5t, this is all gross and lots of other rules and permits come into it. A basic two trailer with a steer, 2 bogie groups and two tri groups would be 6t+16+16+20.5+20.5=79t gross. Take off say 10 for primover, 14 for two trailers and 2 for dolly so tare of 26t gives a mass of 53t. Than there permits and mass, lighter tare weights and more axle groupings and bigger axle groupings come into play.
Our roads also take a sh!t kicking to though.You guys don't gain very much over our superbs. .. we do 45 tonnes on a new trailer. .. and have 4 less axles!
A two trailer road train with out mass is not much batter off than a bdouble on mass. 6+16.5+23+23=68.5t on mass for a bdouble, a set up on the light side tares at 23t to give 45.5t mass. Mass management is worth 2.5t on tri group and 0.5t on bogie group.You guys don't gain very much over our superbs. .. we do 45 tonnes on a new trailer. .. and have 4 less axles!
what set up has he got? How close to 53t can he run? 53t on a bdouble leaves a tare of 15.5t.Our truck driver has doubles as that is all he is allowed in this area. He tries to get as close to 53t as possible on so he is still legal.
