Surely the most important factors are that the ground you tip on is firm and level.You are correct and I often pull a bulker. I recently had a tip where it turned out that there was about 5 ton stuck at the top of the trailer. It’s not uncommon for bits to get stuck but on this occasion I (got out and looked)
(GOAL). No shunting back and forth for me - get the shovel
It’s an ok strategy with the tub lowered much easier in a rigid though.

OAD a lot of modern pto won’t engage with out the handbrake on which is why it’s better to by pass pipe it your self .
Hadn’t thought of that another safety feature that sounds like a good idea to someone sat at a desk not doing the job.
For anyone that doesn’t follow what I mean they might have experienced a similar thing when dumping the air out of the trailer suspension and when you release the park brake in the unit there’s suddenly this big release of force that’s wound up in the wheels.
Handbrake interlock is the correct name . Petrol tankers always used to have it .
It really needed to be in line, no reason that it couldn’t have been looking at the video, at least then it wouldn’t have crushed the cab when it went over. Very sorry for the unfortunate driver though. Had plenty of arse clenching moments tipping across slopes when I was on eight wheelers for 20 years, with dry stone an old lad told me when I started to just shoot the body up as fast as you can and don’t ■■■■ about, the body will sway over until the material shifts but usually the load moves quickly and it all straightens itself up again. Scary but it usually works. With tipping tarmac across a slope (MIRA test track, hillsides etc) I have had the rear wheels on one side come off the ground more than once but it never actually tipped over, the rams occasionally get wedged on the collars when the body comes back down though which can be fun until you get on level ground again! As Dan said, the tipper bar can slide out if the collar comes off without realising it, we had a couple do that but luckily didn’t go over, or the pivot brackets can break, plenty of possible reasons but the tipper job is supposed to be easy isn’t it?

If you watch carefully, you’ll notice that the guy “helping” was on the cat walk of the tractor, trying to free what I assume to be the Hydraulic hose, as the body lifts, I’m wondering if the tension caused to the front n/s of the tipping body, with the hose snagged on it, was enough to start the roll to the nearside, which once started would be almost impossible to stop 
I remember some 25 years ago when I was a green as grass newbie, being at Krona Span with an artic tipper full of wood chips, Once the body was fully extended, about 4-5ton of the stuff remained stuck at the head board. I thought I’d be able to let it down, but as I did this, there seemed to be to much presure on the hydraulics, and Oil was leaking or being forced out of the resevior over flow or breather or whatever that bit was. At that point one of the 360 log grabs came over, having watched Me having trouble, He gestured Me too stand aside, and then grabbing at the stuck woodchips with the log grab. The body was swaying all over the place, and I was thinking about how I was going to word the phone call, as I had been warned to be carefull with the body raised. To My relief though, and through the dexterity of the 360 driver, within a few minutes he had it empty. panic averted
Only tipper experience I’ve had was for a mate, holiday relief in the 80s
I still remember today what he stressed to me time and time again before I went off with it,…Tip on as solid a ground as poss, and keep unit in line with trailer, surely that is basic stuff is it not, you tipper men?
Ok, the poor lad paid for his mistake with his life, but surely he should have known better you would think.
■■■■ that for a game of soldiers, ive tipped in all kind of conditions but that was really bad on his part
Have no much experience with Tippers. But Dad had always a 10 Liter Spray Bottle with him. Such one you pump up with the Handle.
Many Loads he had to spray the Tipper inside to avoid Load sticking to the Side.
own account driver I recon you are on the ball with the brakes on point,many times when I had to take first timers out and they started to unload with the parking brake on and the drives starting to lift and me reaching across and pushing it off and the outfit jumps forward.
I had a few scary moments tipping deep litter from chicken farms at Eye airfield, to exposed to any wind, the company I worked for then had a couple go over, but to the best of my knowledge no one was seriously hurt. In the end I asked to be transferred to pulling tilts out of Felixstowe dock as a bit safer and peace of mind. And who in their right mind would want to do that !!

I went onto Tilts after tippers too, but from Great Yarmouth to begin with
No problem with the load in that video. Evenly loaded and not one sided. Driver parked at a stupid angle, and the other guy was bloody stupid/thick/retarded to even think of climbing on the trailer as it tipped. Get caught doing that in this country and you’d be looking at a ban from the quarry operator.
The only time I felt happy tipping the trailer was at the bio power station at Thetford, it was on the level and inside !
Looking at how the guy parked it was never going to end well. As has been said before there looked to be a bit of a twist/ tension in the trailer chassis before he tipped causing the body to lean as it was going up. I used to take frag up to Hull and there was nowhere level to tip the usual practice was to tip as fast as you could, it would be nearly half way up before anything moved and when it did it REALLY did and the body would sway about a bit! Not my favorite place to tip. Going back to the video if the driver had the park brake off as the load was discharged and built up behind the trailer it would then push the trailer in s straight line causing more problems as the tunit would be pushed sideways which is why you always have them in a straight line.
And never take someone else’s word on how firm the ground is, only got this a couple of feet off the chassis when it didn’t look right.
Around the same time I was on my mate’s tipper, another lad I knew had this bloody awful contraption of a tipper.
It had a donkey engine, and as far as I remember it was not on a ram, he had to disconnect the trailer brake, and the trailer wheels moved forward, but the unit brakes stayed on, so the load tipped as the trailer went up in the air, a ■■■■ hideous piece of kit it was, that just looked dangerous. th
They are more than likely illegal today but it was 30 odd years ago…or did I dream it?

I think the Yanks still use them
Chuck it out the side!

They certainly do. Can’t say as I’ve ever seen them in Canada though. The tippers here are much like in the UK, although I believe you’re supposed to dump all the air before tipping and none of them have proper on board weighers like in the UK but rather very haphazard air pressure gauges, one on the trailer axles and one in the cab for the drive axles.

you are describing the old hoyner trailers . put the unit brakes on and the trailer is drawn towards the unit . take the red airline off when tipping in a hopper and the unit is drawn backwards . i pulled one for a while and it was a pain in the bum to operate . dave
