sounds like a load of old crap.
you’d be [zb]ed on the ice.
i wouldn’t take it out.

It doesn’t matter what gizmos you fit, there is no arguing with gravity. It might take more to tip it but once you roll too far you will end up on your side.
Watching the demo vids, I doubt it would get any were near to going over.

And I shouldn’t have thought a driver would push as hard as those guys are on public roads!!
Had it on a tipper trailer a couple of years back but the fitters disconnected it as they said the unit pulling and the trailer braking was putting too much stress on the trailers ally chassis and making the welds crack
Anyone remember the trailer brake fitted on the Scania 110 that was mounted on the steering column ?
Worked a treat IMO.

Yes, great for straightening out a jack knife if you caught it quick, they also had a trailer protection valve that would cut the air supply to the trailer if you had an airline blow, good ideas lost in time.

I’ve had this on a few trailers, 1st encountered it on a Maritime skelly, so it’s been around a few years.Our trailers (at least some have it) as it’s kicked in on the sliproad from A57 onto the M6(s) where the Mercedes garage is, knew what it was, but certainly wasn’t going too quick - and was empty too

the way that EBS works is, it measures the air pressure in the suspension on both sides of the vehicle, when the pressure in one side is greater than the pressure in the other side by a fixed percentage (can’t remember the actual figure), it applies the brakes, this in turn helps prevent roll overs by slowing the vehicle down until the pressures are equalled out againEBS is Electronic Braking System
ABS is Antilock Braking System, will stop a skid, but not a roll over
I think the EBS system also works by keeping pressure in the brakes and using electrical signals to activate the brakes, so is much quicker and can alter where the brake pressure is - ie which wheel.
Sod roll overs, I want an anti-jacknifing system. Anyone who’s used a rental trailer will most likely have noticed how [zb] the brakes are on the trailer.
A few years ago (quite a few) I was pulling a fully loaded trailer, quite heavy, down a hill and it was icy / snowing, started the hill pretty slow, but trying to keep the speed down was very hard, touch the brakes, trailer brakes came on 1st, but a split second later the unit brakes came on more powerfull and the trailer started to shove the unit round, so off and on the brakes all the way down and still hit the bend at the bottom at nearly 30mph - luckily it gripped around it because there was sod all else I could do.
Yes, EBS sends an electronic signal which is quicker it still has the normal air circuit as back-up though. It does fancy calculations that control how much pressure is applied to an individual brake chamber based on the load on that wheel. I never really feel an EBS trailer makes you think wow this feels safe braking compared to one without though.
Electronic stability control is the more interventionist system that’s designed to prevent rollovers and jacknifing etc.

Not quite. Ebs uses an electronic signal from the t/unit to the modulator valve mounted over the trailer axles. This then distributed the air to the brake chambers, as requires. A 2 modulator system has a modulator for each side, ie one works all the off side brakes, the other all the near side brakes. If an ESP system is fitted it comprises a g sensor that detects the sideways forces. If the g sensor detects sideways forces above a limit it apples the brakes on one side of the trailer to bring that side “down” again. Modern systems can be configured for different forces so if on a certain job the ESP keeps kicking in you can make it less sensitive.
The air pressure in the air trailer air suspension system is the same in both sides, they just tend to be piped up separately.
The ebbs signal travels along the big abs/ebbs suzie. If the trailer is fitted with ebs you could disconnect the yellow airline if you wanted, the brakes would still work fine. The yellow line is retained as a backup in case the electronics fail.

I bet a couple of drivers mentioned on these forums wished there trailers were fitted with the system!! Woulda saved a few red faces, IMO!
