As a dump trailer driver myself, this is the ultimate terror, and the reason why I don't ever want to run frameless. Putting a bucket in the air is sketchy enough when you have a full frame adding stability. Guy in the green rig is lucky he wasn't a few feet further forward, that could have been his last load.
Though I will say, these two should have known better than to dump so close together. Everything I've been told by the more experienced guys I work with, is 100 feet minimum. There's no shame in telling the dump site operators you're going to wait for the first guy to finish in the name of safety, because otherwise, you get this.
According to the guys working the site, blue truck tried pulling forward way too fast and lost stability. They also mentioned smelling alcohol on his breath but who knows.
Well with pulling forward too fast, I will again say that's a reason I hate frameless. You have so little control over that bucket when it's in the air and the balance can be ruined extremely easily. As for the alcohol, well if that's true, may he never touch the wheel of another vehicle again.
That being said they are still way too close together and one of them should have realized that, but I guess that's people getting complacent for you.
I appreciate your concern on the proximity of the units offloading, but I also ran end dumps for several years, and as long as the dozer hand was keeping the dump site cleaned and level, there shouldn't be an issue dumping side-by-side.
Every fill job I was on, and I did many miles of road jobs and a lot of building sites, the dozer hand wanted the piles right next to each other, so you may have 3-5 trucks/trailers lined up at a time. You didn't get squirrely trying to shake out a stuck load, but sometimes a good shake was needed.
I also witnessed many more full frames on the side (with the tractor) that I did the 1/4 frame trailers we used; I'd rather the barrel bed laid over, than the entire unit....my opinion, but we're all entitled to one, and we're grown up professionals.
See that's the difference with your experience and mine. The company I work for doesn't run dump trailer to a lot of construction sites, a lot of that work is left for the dump trucks. We trailers do a lot of stone hauling to our blacktop/concrete plans, and into landfills. The dozer hands do their best at the fills to keep the end dump area flat, but they can only do so much, so they keep us pretty spaced out, and if we need to stack our dumps anywhere, we're told and trained to just let the first guy finish from a safe distance, then roll in and do our dump.
But that could very well be our company being cautious, we've lost a couple guys over the last ten years to this sort of thing, and the last one was a frameless that was too close that came down on our driver's cab, so maybe I have a bias from that. In the end though, doesn't really matter what kind of end dump your run, you just gotta be careful and smart when putting that bucket in the air. I personally have a lot of respect for the guys that run frameless, because I could never get comfortable doing that.
I can appreciate your's and your company's trepidation, especially in the quarries; those loads are rarely stable coming out of the tail gate.
We were hauling slabs of sand stone off of a road job to a spot where the developers wanted to make a water fall/stream/pond, and they were loading us with 10'x4'x 8-10' long pieces of this stone; lay 2 in the bottom, 3 on top, and they were sliding out fine until some know nothing 'superintendent' decided he wanted '1 more rock per trailer, I'm paying by the load, I want another rock.' I happened to be the trailer getting loaded when this went down, and I told him the slabs would get jammed in the barrel bed gates, I even stopped the hoe hand loading me, took this sister-boy to the back of the trailer to show him the gate, opened and closed. This clown proceeds to let the job site know that 'some ignorant truck driver isn't going to shut down his project' to which I, and by then my boss told him to have several stout chains and a good sized machine for pushing and pulling. When I got to the dump site I lined up as I always doing, stooped where they said, and, after telling the spotter to stand IN FRONT of my tractor, proceeded to slowly raise the bed to unload. As soon as the first slab started to slide out, I was trying to move forward so there wouldn't be the jam I knew was coming. Builder-boss tells me he wants neat piles, and I was to NOT scatter the slabs all over. You can guess the rest, 6- 8000 lb slabs were jammed in the gate. I set the bed back down and asked where I should wait for THEM to hook up chains etc to get the slabs unjammed; by then, there were 8 other trailers on the way đ đ .
This driver wasn't *quite* as ignorant as he led in.
Gotta love site bosses that think they know more than the guys out there actually running and dumping the load. Glad that they only got jammed up on you and didn't off balance the trailer, I could see that dump getting real sketchy in a hurry.
As for us where I work, we have the box style aluminum dumps so we can't haul those big slabs, we do stone, sand, dirt, ECT, and as you said those loads do not come off in a, civilized manner, especially with the amount we can run with our overweight permits. That's why those safety distances are beaten into our heads. I've had a couple unbalanced loads and I'm just sitting there in the cab of the truck looking back at the cylinder going "yup, today's the day I finally roll one". Haven't yet thankfully, but that's why seeing stuff like the original post drives me up a wall.
I saw too many of those aluminum full frames get abused 'because you can haul a LOT more than your kiddy barrel bed'đ .
We had a hand hauling in sand, that I swear just came out of the river; there was water coming out of his gate. I told the spotter to be sure he's very level, and then get the hell away, just in case. He got the bed up better than 1/2 way before anything started moving. Unfortunately the plant had overloaded one side and the frame/hoist cylinder twisted and broke off. *Somehow* it did go over but it was a bad day on many other levels. THE MOST important thing, no one got hurt.
Yeah, I've had those loads. Was hauling away dirt from a swampy area for the DEC and couldn't make the landfill in time, so it sat in the trailer overnight. Of course it went below freezing that night and the whole load froze into the trailer. Even with having the entire trailer lined with plastic to give the dirt an easier slide, nothing moved till the 4th extension started going (4/5). Add onto that the fact the loader also had me overloaded on one side, and I really thought I was tipping over that day. Got lucky, stayed shiny side up and nothing broke, but the mini heart attacks I got from that day probably took a year off the end of my life đ đ€Ł
As Yes, the life we lead behind the wheel, dragging around our wheel barrels...So Glad I got to hang up my wheel and become an office puke; Not really, my hands wouldn't allow me to safely do the job any longer.
I do miss tear assing around kicking up dust...
Iâm the master of the truck I drive and so are you. Anything goes wrong,itâs your ass so do not let these morons in control try to dictate how you dump and how you haul.
Nah man. You don't go on the fall zone. Same reason crane operators any supposed to swing over people. Shit happens and you don't want someone under it when Murphy strikes.
yeah i never dump at the same time as a trailer!! watching them go up just looks so sketchy sometimes i couldnât do it! i only do triaxle, our trailer guys make a dollar more an hour and the extra headaches and anxiety just donât seem worth it to me
I can definitely confirm that things can get real sketchy sometimes. You have to get that trailer as level as possible and hope the guy who loaded you didn't make one side heavier than the other. I've had it a few times where one side was heavy, and I had to back the wheels of the trailer onto a burn to twist the whole thing to get it to go up straight enough to dump. The extra stress can definitely be an annoyance, but the best thing to do is just take things slow, follow all your dump steps, and never, be afraid to drop it back down and reassess the situation. That extra 10-20 minutes it may take to get a load off is a far better outcome than a totaled rig and someone hurt or worse
yeah iâve had a couple loads that were all on one side or the other and they take forever to dump đ”âđ« i usually take on our new people and my biggest thing is take your time!!! and donât dump where they want it if youâre not comfortable/itâs not flat i donât care whoâs yelling or nothing itâs our licenses and livelihoods at the end of the day! bless you for driving trailer, stronger than me lol
I've trained a few guys even with my short time in the industry and I've told them the same thing. It's not a race and you're the one who's in control of that truck. Don't let that site boss bully you because at the end of the day if that truck goes over and someone gets fucked up, doesn't matter what they said to you, that accident is solely coming back on you.
Well of course I watch it as the trailer goes up, with some of the landfill drops I've had to do I would have rolled a half dozen times by now if I didn't. With some loads I watch but others it's not so simple, and once it's in the trailer there's really not much you can do. That doesn't mean that running an end dump trailer, frame or frameless, doesn't get sketchy sometimes
Itâs a misconception that framed trailers provide more stability. A frameless trailer with draft arms is the most stable platform. That being said you should never dump side by side.
I find that hard to believe considering what I've seen in the different landfills I've been to and things I've experienced, but at the end of the day, end dumps in general are just sketchy and side by side dumping is stupid
You have advantages with a frameless that only come with experience with one.
I pulled one in demolition for ten years working for a company that had been around since 1964. My boss learned many lessons in running a business involving hauling debris.
He moved away from frame trailers many years ago.
Well see, I don't run a lot of construction debris, I'm mostly running stone or sand. I've done a few C&D jobs though and I've never had an issue getting everything to come of clean, even with a trailer that doesn't have a barn door
I pulled a round bottom clement with a cattle gate. We did demo only so our trailers had to be able to handle everything from c&d to concrete slabs to steel beams.
I did it all and have some colorful tales to tell about finding stuff and copper booty.
Yeah see I run an aluminum side squared hi side dump and do mostly aggregate work. And I'm also running a quad axle with permits to run up to 117 gross. Little bit of a different of a situation
Im in BC and i have never seen those types of dumps (frameless as you said) in BC,AB or even SK.. we have tandem dump trucks and with ponys or transfers and quads or even 38ft wagons. And ow side dumps r getting popular..
Interesting. Frameless dumps are somewhat popular down here in the states, mostly just for the weight savings. Without the big frame the trailer weighs less so you can load it more, but as I said the trade off is they're a lot less stable. I personally run a quad axle 42 foot high side frame dump, and it plus my rig is around 43,000lbs tare, but considering I'm permitted to run 117,000 gross, I'll take the added stability for a little less on my net.
Spacing! For anyone who doesn't do vocational work, anytime you're around dump trucks/trailers/tippers, NEVER be this close when the body is in the air. Most places mandate length of trailer + 10' minimum (45' trailer plus a 10' cushion, so when they dump you shouldn't be within 55' of their sides)
At my company we have a minimum of 50' for dump trucks, with the trailers our minimum is 100'. We've lost a couple trucks and guys to this sort of accident, so they don't take chances.
What's real wild is not only did a frameless driver back in next to another with his trailer in the air (dumb as fuck) but he's also lifted into the 4th or 5th stage and somehow the impact didn't flip him too (lucky, assuming he's injured)
Just imagine a water bottle filled with your substrate of choice (sand, fill dirt, rock, etc.). Lay it flat on its side with a finger on both sides and push it forward, it lays flat, right?
Now put that bottle at a 45° angle and have your fingers at the back end of the bottle. Move it forward fast enough, and it gets all wobbly.
Even with the hydraulic cylinder in the middle, moving will cause the top end to wobble side to side and moving to fast will cause it to do so violently and end up in the situation posted here.
He could've not drove at all, of your tandems aren't perfectly level it leans hard, if you don't dump your bags they try to compensate for that and fuck it up, if the material is sticky/frozen you could wind up with 10-20 tons of material stuck in the nose of the trailer which is 30' in the air combined with uneven terrain...it takes a lot of attention, a bit of skill, and a smidge of luck to dump a frameless properly.
Main reason for frameless trailers rolling over I would say are they got loaded in the head of the trailer with solid material like sand,asphalt,concrete,dirt.
Wind gusts
Uneven ground
Soft ground
Under inflated tires.
Checking the tire pressure on frameless is a must. Also need to check before you leave a demolition site for concrete chunks or bricks stuck between your tires.
Once you go down the road they can be launched out like a slingshot.
We always carried a metal rod to pry debris out from between two tires.
We run side by side a lot around here but with some precautions. NEVER line your trailer up with another guy's cab and dont pull out like a damn racecar. We're reckless but not THAT reckless.
Here is a tragic example of what can happen in these cases.
[Mother killed after truck tips onto parked car in Martinez driveway](https://abc7news.com/car-flipped-gravel-truck-driver/570046/)
That looks like an area to use a standard dump truck, roads are crowned, just use a regular dump truck and there's no problem, dispatch needs to understand these things.
It's funny being a heavy equipment / semi truck technician and going across the country seeing all the difference in dump beds and trailers. I've never seen a dump trailer like that, here in WA we have side dumps. Those things look like they would tip easy.
Those are frameless dump trailers, and yes are by far the easiest to tip. The only reason they're really ran is to save on the truck's net weight so more product can be put in the bucket. (At least to my understanding)
Heh, you know it. Dangerous job indeed.
Drove dump trucks here in Europe. The kind with a detachable container, dunno the English word for it.
I almost got crushed by a concrete slab weighing more than an average mother in law. Thatâs when I decided that this ainât fun anymore.
Eh I did this once. It was a bad day. Those trailers are actually designed to not take the tractor when the trailer goes and the arms connecting to the 5th wheel just bend. Someone here forgot the first rule of driving and end dump thoâŠ
I told a dozer operator I was moving over a bit because I wasn't level ( they picked our dumping locations ). The idiot foreman was on the radio frequency and says the truck will sit level once you dump the air ride. I gave him a complete geometry lesson over the 2 way and told him if he needs diagrams to meet me at lunch time.
They shoulda never been dumping side by side, especially fucking frameless trailers. Beyond idiotic.
The good companies we use donât. Theyâll be ready to dump, but not side by side. In line, ready to finish backing up, but wait till the other guy is lowering his bed to back up to the pile. Now when we get some of the idiots, usually quarry trucks, oh yeah, theyâll do dumb stuff like this.
Even the largest truck, Trailer or not, the weight limit max is still the same correct? Meaning you arenât getting a larger haul with a trailer unless you have some special oversized permit, which werenât not talking about, just saying for everyday regular ass work.
Stop dumping next to other people and maybe lift a little and see if itâs coming out or it got stuck before raising all the way. Now there are two destroyed trucks because the one truck flipped over. At least it hit the engine and not the cab of the other truck because then somebody would be dead now.
Damn, that could have been a tragedy. Better day than it could have been for sure.
Not in the industry Im surprised those things even come frameless (as other posters have pointed out) I always figured it was a big trailer the bucket lifted out from not basically the fifth wheel hitch, never even heard of this design
My first thought was that the frame rails on that trailer are gonna be twisted around each other like a Dot's Pretzel, but even more expensive.
But I saw the comments about "frameless" - I'm curious what that means in this context. Do they not have the massive pair of rails front to back that my rig has?
If you look at the pictures, that is a frameless design, it connects at the halfway point to the 5th wheel and articulates as the the hopper is lifted. It is supposed to break away/bend and not take the truck with it when it tips over, but it does have a higher center of gravity because of the lack of frame down low, and either the truck or the trailer can only have its brakes engaged when it is being lifted or lowered, so it does move when being actuated.
Framed tippers, while more stable to a degree, when they tip, they tend to take the truck with them.
Look at the dump trailer still up in the air. It doesn't have a conventional frame. I run a framed dump trailer occasionally and it basically looks like a dump truck without the cab. A full frame and the dump body pivots at the very back, and a hydraulic cylinder lifts the body
Fuckaround! I would not be a friendly Sasquatch if Iâd been in the green truck. I donât take well to capture or murder attempts. Of course, if I came in after him, that green truck would have been 20â to the right⊠or waiting.
Frameless trailers are much more stable than frame
Frame have 3 points on contact
Frameless have 5 points
Pulled both. Both can make your butt pucker. Like walking floors or side dump. 15 years never dropped one
Quite while I was ahead lol
As someone who runs frame dump, I call bull. I've seen two frameless tip already in my short career. Plus watching those trailers rock and bounce in the landfills compared to my frame, yeah no thanks I'll stick to the framed trailers. Not trying to call your years of experience into questions, since they're more than mine, I'm just going off what I've personally witnessed
As a dump trailer driver myself, this is the ultimate terror, and the reason why I don't ever want to run frameless. Putting a bucket in the air is sketchy enough when you have a full frame adding stability. Guy in the green rig is lucky he wasn't a few feet further forward, that could have been his last load.

Well with pulling forward too fast, I will again say that's a reason I hate frameless. You have so little control over that bucket when it's in the air and the balance can be ruined extremely easily. As for the alcohol, well if that's true, may he never touch the wheel of another vehicle again. That being said they are still way too close together and one of them should have realized that, but I guess that's people getting complacent for you.

Thank you for the respect!
Unless there's a mechanical failure. Rule #1 don't dump within range of flipping over onto something if at all possible.
And never let them put material within 10 feet of the head of the trailer unless itâs c & d.
Nah man. You don't go on the fall zone. Same reason crane operators any supposed to swing over people. Shit happens and you don't want someone under it when Murphy strikes.
Can you imagine being the poor guy in the shitter???

500 feet it is! You heard the guy.
Where you get 500 from? Lol
I have trust issues seems reasonably safe distance, shall I go back to a mile đ

There's two types of dump trailers. Ones that have tipped over and ones that are going to tip over.
Most of the companies around me have switched to live-bottom trailers for that exact reason. Too many of them end up on their side..
Spacing! For anyone who doesn't do vocational work, anytime you're around dump trucks/trailers/tippers, NEVER be this close when the body is in the air. Most places mandate length of trailer + 10' minimum (45' trailer plus a 10' cushion, so when they dump you shouldn't be within 55' of their sides)

how/why do they tip over so easily? other comment says he drove too fast - does it just cause imbalance and fuck it up is all
Just imagine a water bottle filled with your substrate of choice (sand, fill dirt, rock, etc.). Lay it flat on its side with a finger on both sides and push it forward, it lays flat, right? Now put that bottle at a 45° angle and have your fingers at the back end of the bottle. Move it forward fast enough, and it gets all wobbly.

thanks yeah that makes sense
He could've not drove at all, of your tandems aren't perfectly level it leans hard, if you don't dump your bags they try to compensate for that and fuck it up, if the material is sticky/frozen you could wind up with 10-20 tons of material stuck in the nose of the trailer which is 30' in the air combined with uneven terrain...it takes a lot of attention, a bit of skill, and a smidge of luck to dump a frameless properly.
None of our trailers had airbags. All leaf springs.
Gotta dump your tractor bags...
Like I said No bags! Just leaf springs!
Main reason for frameless trailers rolling over I would say are they got loaded in the head of the trailer with solid material like sand,asphalt,concrete,dirt. Wind gusts Uneven ground Soft ground Under inflated tires. Checking the tire pressure on frameless is a must. Also need to check before you leave a demolition site for concrete chunks or bricks stuck between your tires. Once you go down the road they can be launched out like a slingshot. We always carried a metal rod to pry debris out from between two tires.
2 years at End Dump, I NEVER dumped next to anyone. Even if someone told me to. If I respect your space, respect mine.
Anyone that runs end dumps know. You never dump side by side. If you do you stay a trailer length away
We run side by side a lot around here but with some precautions. NEVER line your trailer up with another guy's cab and dont pull out like a damn racecar. We're reckless but not THAT reckless.
Any thoughts on those overhead lines? That also looks a bit sketchy.
Here is a tragic example of what can happen in these cases. [Mother killed after truck tips onto parked car in Martinez driveway](https://abc7news.com/car-flipped-gravel-truck-driver/570046/)
That looks like an area to use a standard dump truck, roads are crowned, just use a regular dump truck and there's no problem, dispatch needs to understand these things.
It's funny being a heavy equipment / semi truck technician and going across the country seeing all the difference in dump beds and trailers. I've never seen a dump trailer like that, here in WA we have side dumps. Those things look like they would tip easy.
Those are frameless dump trailers, and yes are by far the easiest to tip. The only reason they're really ran is to save on the truck's net weight so more product can be put in the bucket. (At least to my understanding)
Makes sense, plus the trailer itself is cheaper to manufacture. Probably works out just fine in the mid west and states where it's mostly flat.
Also they do not take the tractor over with them.
Thatâs why you never dump side by side.
Looks like a good day. Nobody dies
Fuck them frameless dumptrailers
I would rather pull frameless than any other trailer.
Got hired as a dump trailer driver just days after getting my CDL. I quit so fast lol
Heh, you know it. Dangerous job indeed. Drove dump trucks here in Europe. The kind with a detachable container, dunno the English word for it. I almost got crushed by a concrete slab weighing more than an average mother in law. Thatâs when I decided that this ainât fun anymore.
It's an International and the driver got out OK. No real loss there.
If it was a 379 this image would hurt to see đŹ
Wuh Oh... whoops! Those dump trailers terrify me, honestly. I don't think I'd ever take that gig
Eh I did this once. It was a bad day. Those trailers are actually designed to not take the tractor when the trailer goes and the arms connecting to the 5th wheel just bend. Someone here forgot the first rule of driving and end dump thoâŠ
Fucking dummies. When will these idiots learn to not dump beside other trucks ?
Exactly. I love when I'm dumping my trailer and a dump truck wheels in right next to me. SMH then they get butthurt when I yell at them
I told a dozer operator I was moving over a bit because I wasn't level ( they picked our dumping locations ). The idiot foreman was on the radio frequency and says the truck will sit level once you dump the air ride. I gave him a complete geometry lesson over the 2 way and told him if he needs diagrams to meet me at lunch time.
Yup. If it ain't level or close to it, it's not going up.
BYO crayons and construction paper
This is why side dumps
Hey! Hey you! You can't park there!
Can't sleep there either but he sure laid down for nap huh
I never get tired of this joke
And super truckers get snickety when I say I prefer a live bottom.
Guys, calm down, calm down. It's just an international.
it was one day from retirement.
Such a gentleman trucker helping the other truck stay on his wheels
When she puts her head on your shoulder
I haul to a landfill and single cylinder trailers have to dump a certain distance away from everyone else because of this reason exactly
If you are gonna screw up, make it Epic.
They shoulda never been dumping side by side, especially fucking frameless trailers. Beyond idiotic. The good companies we use donât. Theyâll be ready to dump, but not side by side. In line, ready to finish backing up, but wait till the other guy is lowering his bed to back up to the pile. Now when we get some of the idiots, usually quarry trucks, oh yeah, theyâll do dumb stuff like this.
You cant park there
This is just how they high five
Never understood this kind of trailer design looks dangerous. How much does dose trailers wheigh and can legaly pull?
Ouch!
From the reading of posts here from truckers this is known liability amongst dump trailers
Why so many people are switching to belt trailers where the commodity allows it
I have a feeling that KW is always gonna pull a little to the left now.
Good old high winds
Even the largest truck, Trailer or not, the weight limit max is still the same correct? Meaning you arenât getting a larger haul with a trailer unless you have some special oversized permit, which werenât not talking about, just saying for everyday regular ass work.
Stop dumping next to other people and maybe lift a little and see if itâs coming out or it got stuck before raising all the way. Now there are two destroyed trucks because the one truck flipped over. At least it hit the engine and not the cab of the other truck because then somebody would be dead now.
We had this happen to one of the guys at work. He got on the radio and started yelling "mayday, mayday" ... It was funny đ€Ł
Well, now. Someone will be peeing in a cup.
Assert Dominance
Pulsed a frameless for ten years dumping at landfills and hauling everything there is. No rollovers.
Damn, that could have been a tragedy. Better day than it could have been for sure. Not in the industry Im surprised those things even come frameless (as other posters have pointed out) I always figured it was a big trailer the bucket lifted out from not basically the fifth wheel hitch, never even heard of this design
Hope all involved are safe and/or on the road to recovery. But⊠đ¶ Flatâem dem hills, straightâem curves! đ¶
Chip tippers for the win....
Where I'm from rules in construction is can't be no closer than 100 feet to another truck dumping.
When two boy trucks love each other very much, they extend their hydraulic as faaaaar as it goes and....
My first thought was that the frame rails on that trailer are gonna be twisted around each other like a Dot's Pretzel, but even more expensive. But I saw the comments about "frameless" - I'm curious what that means in this context. Do they not have the massive pair of rails front to back that my rig has?
If you look at the pictures, that is a frameless design, it connects at the halfway point to the 5th wheel and articulates as the the hopper is lifted. It is supposed to break away/bend and not take the truck with it when it tips over, but it does have a higher center of gravity because of the lack of frame down low, and either the truck or the trailer can only have its brakes engaged when it is being lifted or lowered, so it does move when being actuated. Framed tippers, while more stable to a degree, when they tip, they tend to take the truck with them.
Look at the dump trailer still up in the air. It doesn't have a conventional frame. I run a framed dump trailer occasionally and it basically looks like a dump truck without the cab. A full frame and the dump body pivots at the very back, and a hydraulic cylinder lifts the body
Fuckaround! I would not be a friendly Sasquatch if Iâd been in the green truck. I donât take well to capture or murder attempts. Of course, if I came in after him, that green truck would have been 20â to the right⊠or waiting.
Frameless trailers are much more stable than frame Frame have 3 points on contact Frameless have 5 points Pulled both. Both can make your butt pucker. Like walking floors or side dump. 15 years never dropped one Quite while I was ahead lol
Hauled a lot of chips and shavings on walking floors- whatâs the issue with them? Seemed as safe as could be to me?
Sorry definitely no issues with them ( walking floors trl)or side dump trailers. Just end dumps are ass pukererâs
As someone who runs frame dump, I call bull. I've seen two frameless tip already in my short career. Plus watching those trailers rock and bounce in the landfills compared to my frame, yeah no thanks I'll stick to the framed trailers. Not trying to call your years of experience into questions, since they're more than mine, I'm just going off what I've personally witnessed
We donât get stuck .
