I’m hoping to move from a 5000kg GVW draw bar trailer to a urban mini artic combination to haul a 4000Kg boat.
I’m now familiar with the ‘D’ factor in order to get the trailer weight distribution theoretically correct, but before I start contacting in earnest perhaps someone familiar with the Regs governing design could help with my confusion.
I think I understand that in the ideal world the pin should bear 1/5 (wheel) of the trailers GVW, and laden or unladen. e.g. 1/5 of 5T leaving 4T on rear trailer axles. I don’t know but perhaps HGV combinations have means by which load weight distribution is measured, before departure!
However, because I plan initially on using the smallest tractor I am mindful of the limitations of the design/plated weight of the rear tractor axle.
I have never seen anything in black and white to reassure me that with max. limits in mind poor pin weight distribution is an offence. Does anyone know for sure please?
