braking system on trailer,

[spuddog0507]

Hi all looking at a possible build of a fast tow timber trailer with a gross wieght of about 5.5 tonne and be able to carry approx 4-4.5 tonne of timber does any one know of what braking system would be required for that weight, air is definatly available oil i am unsure on that at the moment, trailer will be towed at up to 56mph so a purpose built timber trialer wont do the job due to design and tyre speed rating, any help will be good to know,

Hmmm, since a professionally built 3500kg flatbed/tipper trailer will weigh 900-1000kg empty, I kinda imagine for a 5500kg gross trailer the chassis, running gear and superstructure could be nearer 2000kg

for the presumably longish chassis required,

and superstructure stiff/strong enough to restrain logs(pure gut feeling, nowt more)

I am also unaware if you are intending to run under an Agric exemption,

or if that even applies for 56mph speeds.

but

I would however have imagined air was mandatory for 56mph.

So cant really help,

at 56mph, I assume you are using a mog or a fastrac,  you have no option but use air, and unless using it on the agri exemption, the trailer must be plated (using it on a tractor, you are limited to 25mph  irrespective of what brakes are firtted, the tractor limits the speed)............., and again unless on agri, it must be IVA'd to comply

Defo want to be on air for that set up.

read the IVA testers manual.

Are you going to get it built by Trailer manufacturer or your self.

built by myself and  ag engineer who has built a few trailers and several forwarding trailers in his time, looked at a trailer he built 25yr ago the other day and it will still be working in another 25yrs.

is there an "old" trailer you could "refurbish" ......this would save the grief of an IVA test.........(read carefully)

been trawling the net all last night and to night and i have just come up with 2 options one is a ex MOD container trailer that would need very little work to get it to where i want and the other is a old stepped arctic trailer the ones with the small wheels on em both would be a cheaper option than starting from scratch with a new one, so i will have to make an execative dession and work out which would be the better option, then i will let you know how it works out.
