I'm not an HE Operator but I've been around construction long enough to know that rain on steel makes things very slippery and when you have mud acting like a sheet of ball bearings between steel track and a steel deck you're going to have problems.
@PARA Trooper This is a clear indication that they need to wait until it isn’t raining and they need to get those huge clumps of mud out of the tracks!!! I saw that as well and I’d bet money on the fact that the mud has a high clay content which would be like spray grease on the trailer before loading the dozer!!!
Hey, old gravel hauler here. As soon, as i started the video, seen the rain/wetness, i knew you'd have trouble. THAT TRAILER is NOT DESIGNED, for loading a cat, in the rain. THERE IS, OF NECESSITY, TO HAVE extra heavy angle iron, welded to the trailer ramps, and even onto the trailer deck, sometimes a wooden deck, just doesn't ' cut it'.....for traction/adhesion in the moisture. Steel, with alotta weight, in the wetness of continual rain, doesn't WORK. (( The bosses son, was '' squished like a bug.''' attempting to do this same thing, when the cat tipped over..... (To quote, his other living brother.......) i wasn't there at the time.....
Honestly, every equipment trailer should have angle iron on both the dovetail and the ramps. Mine had it on just the dovetail, because the ramps were so short that it wouldn’t have made a difference.
The trailer is ok,it's just that he misses,as you point out,angle iron on the ramps,and bolts on top of the trailer to secure it from sliding sideways. What these guys do is idiotic. Even i have done the same numerous times my self,in winter time too. I'm an idiot...haha
As someone who, comes from a Heavy Haul Transportation, that’s what a Low-Bed, Step-Deck, a Beam Trailer’s are DESIGNED FOR!!! FOR F-Sakes BRING THE RIGHT TOOL FOR THE JOB!!!
@Chris Maginnis We use to have the same problem a lot of the time. We got some old conveyor belts from a mine and put them on the ramps when we load. It makes a load of difference
guy I used to work for used old conveyor belts and some keep a few tires but most have nothing. Ive only slipped back myself once in 17 years and it was the same situation as the video where it was raining and the truck was pointing uphill which made the ramps steeper. Scared the shit out of me.
Damn why would you move something like that in the rain anyway without proper equipment to do so or do it at all? Just seems so dangerous and I’m surprised the tires in the back of trailer don’t pop
I run into this problem every-time its wet because of flush ramps but there is an easy solution. Just hook a log chain to the trailer and lay it down the middle of each ramp. The track cleats can then grab the links of the chain and you can cruise right up with no slipping. Easy and quick.
Back in about 78' my friend was putting a Case crawler on a Miller tilt top one snowy icy morning, just at the point when he reached the apex & the top was about to close back down the tracor spun off the side! He's a highly skilled operator but also lucky in every way his whole life no matter what he does, and this was one of those days. When the tractor hit the pavement on it's side, my friend was somehow unscathed & standing right inside the rollcage! When the Sherriffs deputy showed up, he walked around the tractor & with a smug look on his face said " I thought you're supposed to have these things chained down when you move em'! My buddy said " I was loading it! He told me the cop felt kind of stupid and just said "oh". Lol
this tractor weights in probably at about 8 tons and is allowed to be loaded up to 26 tons (7.5 on front wheels, 11.5 on drive and 7.5 on the rear lift axle, but total no more than 26 tons) so there are about 18 tonnes needed on the tractor to fully load it. the trailer adds on the truck 3 or 4 tonnes, maybe, so lets say 14 tonnes of that load need to rest on the tractor so I think this is about right.
alot of guys will just keep the engine running if its a short run For those that dont know why Its not blow back that causes the turbo to spin (most of the time) It is the ventury effect The exaust pipe becomes a vacume Kinda like a carbrator And it will suck every thing from the valves open to oilseals out
I live in Alabama and recently ran into this when I bought a TD20B from up in Tennessee and had it shipped in. Alabama required a front escort and rear facing position if wider than the bed. Apparently from my understanding a governor had a family member killed by a "bladed" piece of equipment.
owned 13 cats from time to time, none quite this big. Loading backwards will give you no more traction, don't know how someone figured that one out. What he needs is welded on heavy metal bars for grousers to grip, or, as Ive used at times, recap off of a thrown truck tread, bolted many places to the ramps so that he can get purchase there.Id have gone for a dry day also if possible. As suggested, lower deck with removeable neck is the best way to go on this one. Also, not nearly enough tie down chains. Pretty dangerous if one breaks.
I've got a D8H of about that vintage - doesn't get much use. I could let you run it a bit if you are feeling nostalgic. I've also got a D6H LGP a lot like the one in the video - gets much more use. Two thoughts on the video - cleats on those wood ramps would help with traction for tracked vehicle loading, and where are the blade guards? I can't haul my D6 (or the D8) on highways in PA without blade guards. I guess they don't use them wherever this video came from.
I am a heavy equipment operator (both Military and Civil ) and it would appear from my trained eyes that the objective of moving a Blade from A to B on the back of a trailer was ultimately achieved 🤷🏻♂️ Whilst not ideal conditions to carry out such a procedure on that type of trailer it is apparent that they have used this setup previously and simply got round the problem by improvising on the day. All the experts out there in RUclips land no doubt have their own theories. But the entire load left as planned.
That actually was the operator of the dozer. Its the UK/Ireland so operators generally load their own stuff. I worked in Canada for a year and noticed that the truck drivers load the equipment. Don't know if its the same in the USA?
Makes sense if you understand the basic fluid mechanics... a high-speed fluid (air) moving perpendicular to an opening (the exhaust pipe) will result in pressure drop at the top of the pipe, which of course creates a pressure differential across the turbine and makes it spin. Although it will not spin very fast of course...
In the last, and successful attempt, you can see wood sheeting on the ramps. The dozer's track can bite into them and the wood can bite into whatever traction aids are embed in the ramp.
if you put grips on them they get torn to pieces. Grip is usually no problem. In the video it was raining and the lowbed was pointing uphill which makes the ramps steeper.
The point is not what stuff you load but that you don't load it on to steep steel ramps while its raining. They have more sensible trailers to load equipment on to in the North of Canada or Alaska where im presuming youre from. I have worked there myself.
Most of you probably never loaded a VW Rabbit on a low bed. Never mind a machine like this, in the rain. You would need an oxygen mask just to sit in the cab.
This is local to me. The reg on the car is from my county and going by the dealership sticker on the rear window, it was bought from a dealership 2 miles from me. Such a small world seeing this on YT
Never had too many problems loading these bigger machines on the patch but small dozers on frozen decks -40 a real heart stopper. Never had one come off but have had to try a few times before successfully getting the small ones on safely.
As an amateur, that's a scary scenario! It wasn't even raining when my rig slipped off the top of the ramps. Pucker factor was high AF! It's neat to see it done better than I could
we don't have enough big equipment to justify side loaders or the other break-neck type. It used to be a lot worse years ago when all we used was tractors and homemade narrow trailors that were too high with too steep ramps.
Looks like an LGP D6. The real operator is generally never around to load/off load the machine.It would have helped them a bit if they kept the blade a low as possible to shift the CG as close to the front of the machine as possible.Most truck driver then to back up when loading but I am thinking pushing the CG so far to the back would have caused more problems,you'd have to use the blade to stabilize to load,it would just turn into a cluster.They did a good job-for a couple of truck drivers. :)
Covering exhaust during transit is cheap insurance something I have done for many years. Some stacks face forwards which can allow dirt-water&possibly allow the turbo vane to turn. Most turbo's like my Cat 650 Crawler are either water or oil cooled I have yet to see or hear of one having sealed bearings because of how hot the turbo gets hours on end. My Cats D-9 came from the factory with a cover in the manual it states stack is to be covered when ever it's not being operated or in transit.
Big fancy trucks look good but cost a lot of money because there are very few in this small country that doesn't have a lot of big equipment. We would make no money if we where not efficient with transportation costs.
Your right about the "double the weight per surface area" scenario BUT this only works IF you also make the GROUND CONDITIONS favorable for a TRACKED vehicle. Coefficient of traction dictates a tracked vehicle has about .90 efficiency in normal dry dirt. Put the same vehicle on ICE and it drops to .12 efficiency. The wet, muddy, metal trailer coupled with the incline of the ramp makes for a very low tractive effort display. So in dry dirt, your example would SHINE :) on a wet trailer not so much
Was sitting in my car having my lunch. That's why I was able to keep the camera dry and the camera was kept steady zoomed by leaning my elbow on car door.
Thanks for that info, I roughly know where that area is, its about the first built up area you come to if you were heading to Dundonald from Newtownards on the A20.
That is the danger zone of flipping the whole machine on its side. Good skills and rubber will do the work. speed isnt always the answer as it would create a spin and tilt the machine
I have done this for 30 years...1st thing wrong ..Put sand and salt on deck.2nd.thing back on it keeps the tracks tight.& push down with blade as backing on.
The flipping breakover point on the trailer gets you every time. The dang machine is on a point pivot and it pirouettes on that hard point. That is if you get there before slipping back. I did this once the stupid way in the rain and I'll never do it again. Especially hard with a hystat since the steerage gets twitchy at low speed.
I take it you were expecting a bulldozer to fall off a moving truck, run over two cars destroying them completely before exploding and catching on fire?
@ JD HOGG... 600 TONS,, really ?? drop a decimal & divide by 2 maybe. good lord.. 600 tons btw is 1,200,000.. thats one MILLION and 200 K lbs.. The only thing capable of that kind of weight is like a Belaz 75710 Dump Truck. the largest in the WORLD.. used in Mining etc..
OK Im pretty sure this wasn't in the USA because of the type of truck so a couple of questions: Whats the GVWR of the trailer and how much does the dozer weigh? Usually something of this size gets put on a 4 axle lowboy where I drive trucks.
That axel count and spread is even over kill for that D6R it weighs 41,900 the only issue is it's a steel ramp and deck with no 3/4 square bar cleating.
It used to be the exhaust had flappers on the stacks to solve any issues in question at this time but the majority of equipments stacks face to the side which helps prevent air or most water & dirt from getting in the stack. I contacted Cat and was told some of the turbo's with thousands of hours on them & with nothing wrong with them have had to be replace because of not being covered during transit this is why they insist they be covered when not in use. I do not play games with my equipment.
Steel decks and steel tracks just add water to make the slipperiest slide in the world and wow what a rush when you ride 50 tons out of control down the trailer
Dude, did you do some scientific study that proves that wet weather wasn't a contributing factor to the dozer slipping? I can tell you now for a fact it is because its happened to me. Its never happened to me in dry weather. 3 things caused the dozer in the video to slip. 1. steel on steel. 2. The truck being parked uphill which makes ramps steeper. 3. Rain which makes the ramps greasy.
Probably one of the main reasons for the loss of traction was due to the width of the tracks rather than the trailer itself and the rain. Rubber mats etc will help
The exhaust is sideways so there is not going to be anything blowing down it even if wind could turn the turbo. With that logic you should then cover the exhaust pipe every time you park it. Id put my money on it being an urban myth amongst the heavy equipment fraternity. Ive had people tell me the craziest things over the years which ive known and proved are bullshit.
Definitely needs some cleats welded onto the ramps and beaver tail section. If all else fails, use 3 or 4 old tires on each side to try and prevent slipping as they did
I don't think anyone is debating the light rain causing the ramp and trailer to be wet was the problem. Truck drivers load/unload equipment all the time in the US, can't be that difficult if a truck driver can do it.
diecastearthmoving is right. when you load dozers backwards they only spin more because of their center of gravity. only small dozers are loaded backwards
In california, real haulers have a BULL PINE bed and the same on the ramps. This wood is useful for really nothing else - stringly, pitchy, and almost impossible to cut on a portble mill without special blade lube, but outlasts oak, and gives fantastic bite to tracks. Saves a lot of disasters. And YES - where the hell are the tie downs on this slip sliding beast? Probably fell off the trailer on the first turn.
What size of dozer is that? I can see where the D designation is but I can't really tell. Looks pretty big compared to the car. A D8 would be my guess.
I will give the operator credit for trying it twice but that's not a trailer for loading anything with tracks I the rain, I've got a dozer trailer with rails running front to back and on the ramps down the center to prevent sliding off, but a man uses what he has.
I know nothing of loading or moving these huge dozers but wouldn't a ramp that has something for the tracks to lock onto be helpful? I can picture a series of ridges running up the ramps that would allow the tracks to literally grab onto and keep it from sliding.
this just brings up the thought of ice cleats. i know thy would destroy the trailer but i have seen so many dozers and excavatrs stuck in stickey situations with all the guys sitting there scraching their heads wondering why the tracks are slipping. they may only be little knobs but sometimes they are the difference beteen geting your equipment out and loosing it for good.
The MAIN issue here is TRACTIVE EFFORT. And one way to increase it is to add weight to the dozer. So if it's 46k you have to add to that number. Your solution only takes the 46k and concentrates it in a smaller area. Coefficient of traction doesn't take into account the WIDTH of the tracks but the WEIGHT that's on the tracks and the traction available from the ground conditions.

Sounds like the guy we had wasnt happy loading the Tractor at 40kph, dont have time to wait these days time is money
I always use old conveyor belting and tyres. Safer, metal on metal in heavy rain is not good.
The cleanest best pleasure.

That would work well, until that clay filled mud dropped onto the wet conveyor belt pieces and then it would be the same result!!!
@@AzzKicker-bz1cb No, the cleats cut right through and grip into the rubber.

operator did good! keep in mind the weather and slipryness on the ramp
Once again...turbo-diesel equipment exhaust stacks need to be covered, while in transit, otherwise the turbo's bearings will dry spin.
How many times do you think he's used the luggage rack?
Been there, High Pucker Factor. Good job to the operator for getting it loaded. I like planking on the deck.
Ahh the old tire trick. That's what I carry too
this tractor weights in probably at about 8 tons and is allowed to be loaded up to 26 tons (7.5 on front wheels, 11.5 on drive and 7.5 on the rear lift axle, but total no more than 26 tons) so there are about 18 tonnes needed on the tractor to fully load it. the trailer adds on the truck 3 or 4 tonnes, maybe, so lets say 14 tonnes of that load need to rest on the tractor so I think this is about right.

They don’t have enough on the truck if they use them all.

That ain't no dozer operator and the other guy ain't no truck driver !! Put some wood down is all you have to do. It's common sense.
if you put grips on them they get torn to pieces. Grip is usually no problem. In the video it was raining and the lowbed was pointing uphill which makes the ramps steeper.
Metal on metal, trains use sand to get traction
Used car tires.
Wood is just as slick once mud and water get on it.
Worse when only one track slips and they spin sideways on the ramps :-)
Two tires for sale, cheap!!! Nice job on getting it loaded. I wonder if it slips when dry or only when the weather is wet?
Welcome to Briton, where the rain is constantly pissing on your soul!
Good informative comment, thanks.
The best thing about the D8H is that you didn't need a heater because the hydraulic tank was your right arm rest.
The point is not what stuff you load but that you don't load it on to steep steel ramps while its raining. They have more sensible trailers to load equipment on to in the North of Canada or Alaska where im presuming youre from. I have worked there myself.
Detachable gooseneck trailers are often preferable for tracked equipment. Failing that, a lowboy needs a winch.
Jester Mclarpet. that's east coast mentality.
No one use them in ireland. Too long and awkward and stupid. And I'd say 80 percent of excavators and so on are move by farm tractors and low loaders
LOL I HATE when that happens BUT then again that is why we put wood on ramps - you have to be smarter than what you are working with
I think he's one of those people who aren't satisfied unless it rolls 10 times and everyone dies in a massive explosion .
Most of you probably never loaded a VW Rabbit on a low bed. Never mind a machine like this, in the rain. You would need an oxygen mask just to sit in the cab.

Like! Driver had a hell of a solution. Kool, The rain is the ice & the tires are the gravel.
loading even small equipment can be tough on wet days
Ive never seen one backed on to a truck ever. Don't know if theres any particular reason why its done that way though.
They did all right. I've put that same dozer on a trailer smaller than that. I wasn't going but across the other side of the interstate.
"Steel on steel, no deal. Steel on wood, good."
Covering exhaust during transit is cheap insurance something I have done for many years. Some stacks face forwards which can allow dirt-water&possibly allow the turbo vane to turn.

wow this is some crazy good video quality from 10 yrs ago
good point
Mr. Right Tire was like, "Bitch you can't hurt ME!!!!!!"
Where is that site, I think its Preston/Leyland/Chorley. It looks very familiar? Who's dozer was it?

Chris Maginnis Where abouts was this filmed in Northern Ireland?
It was a development called "Cooper's Mill" between Newtownards and Dundonald.
Thanks for that info, I roughly know where that area is, its about the first built up area you come to if you were heading to Dundonald from Newtownards on the A20.
You called Cat,Komatsu and Volvo! Dude, that's like so OCD.
Belfast, Northern Ireland to be precise.
Helium balloons, that's the answer.... you're going to need a lot of them, though.
That is the danger zone of flipping the whole machine on its side. Good skills and rubber will do the work. speed isnt always the answer as it would create a spin and tilt the machine
I have done this for 30 years...1st thing wrong ..Put sand and salt on deck.2nd.thing back on it keeps the tracks tight.& push down with blade as backing on.
I didn't realise there where drivers in those wind turbines. Must be a lonely job on the ones out at sea.
They did that and got it up third time.Its in the video if you watched longer
The flipping breakover point on the trailer gets you every time. The dang machine is on a point pivot and it pirouettes on that hard point. That is if you get there before slipping back. I did this once the stupid way in the rain and I'll never do it again. Especially hard with a hystat since the steerage gets twitchy at low speed.
A couple 2X12s on the ramps rather than TWO tires(10 would have been better) will stop the metal on metal sliding. (works every time I load a Dozer).
Or maybe they didnt have random bits of 2X12s with them
Please describe how covering the exhaust keeps the turbo from dry spinning.
Good job for loading it :)
You've joined the forum and posted 100 serious no spam posts then?
Its Belfast, Northern Ireland.
I take it you were expecting a bulldozer to fall off a moving truck, run over two cars destroying them completely before exploding and catching on fire?
@ JD HOGG... 600 TONS,, really ?? drop a decimal & divide by 2 maybe.
good lord.. 600 tons btw is 1,200,000.. thats one MILLION and 200 K lbs..
The only thing capable of that kind of weight is like a Belaz 75710 Dump Truck. the largest in the WORLD.. used in Mining etc..
I guess you just don't get out that much. The reason that exhausts are covered precisely that, to keep from dry spinning the turbo.
Its not like an excavator, you cant push yourself up with the blade.
Why do that when the action was only 30 seconds in?
OK Im pretty sure this wasn't in the USA because of the type of truck so a couple of questions: Whats the GVWR of the trailer and how much does the dozer weigh? Usually something of this size gets put on a 4 axle lowboy where I drive trucks.
That axel count and spread is even over kill for that D6R it weighs 41,900 the only issue is it's a steel ramp and deck with no 3/4 square bar cleating.
Good job , guy kept calm and took time to square the machine up before trying again.
It used to be the exhaust had flappers on the stacks to solve any issues in question at this time but the majority of equipments stacks face to the side which helps prevent air or most water & dirt from getting in the stack. I contacted Cat and was told some of the turbo's with thousands of hours on them & with nothing wrong with them have had to be replace because of not being covered during transit this is why they insist they be covered when not in use. I do not play games with my equipment.
ive used them before, a good trucker will have them for situations like this.
Steel decks and steel tracks just add water to make the slipperiest slide in the world and wow what a rush when you ride 50 tons out of control down the trailer
about 20 tons
There's never any velcro around when you need it.
oh, and the 5th wheel on eurotrucks is a lot further forward than on the american ones so some of the cargo weight goes to the front wheels
Been there, done that. Steel tracks and a wet steel deck don't go together at all!
Dude, did you do some scientific study that proves that wet weather wasn't a contributing factor to the dozer slipping? I can tell you now for a fact it is because its happened to me. Its never happened to me in dry weather. 3 things caused the dozer in the video to slip. 1. steel on steel. 2. The truck being parked uphill which makes ramps steeper. 3. Rain which makes the ramps greasy.
If you look closer you will see the chains behind the lower idler, and around the tracks at the front.
Probably one of the main reasons for the loss of traction was due to the width of the tracks rather than the trailer itself and the rain. Rubber mats etc will help
The exhaust is sideways so there is not going to be anything blowing down it even if wind could turn the turbo. With that logic you should then cover the exhaust pipe every time you park it. Id put my money on it being an urban myth amongst the heavy equipment fraternity. Ive had people tell me the craziest things over the years which ive known and proved are bullshit.
Glad it turned out OK. I was afraid that it would be one of those videos where the Cat ends up on its top.
Definitely needs some cleats welded onto the ramps and beaver tail section. If all else fails, use 3 or 4 old tires on each side to try and prevent slipping as they did
I don't think anyone is debating the light rain causing the ramp and trailer to be wet was the problem.
Truck drivers load/unload equipment all the time in the US, can't be that difficult if a truck driver can do it.
it is a CAT! why do people always misinterpret this term?bulldozer is smaller than a cat.
So you can confirm this dry turbo spinning in the wind thing is bullshit?
Odd, I always thought the wind drove wind turbines. Do you create the wind?
diecastearthmoving is right. when you load dozers backwards they only spin more because of their center of gravity. only small dozers are loaded backwards
In california, real haulers have a BULL PINE bed and the same on the ramps. This wood is useful for really nothing else - stringly, pitchy, and almost impossible to cut on a portble mill without special blade lube, but outlasts oak, and gives fantastic bite to tracks. Saves a lot of disasters.
And YES - where the hell are the tie downs on this slip sliding beast? Probably fell off the trailer on the first turn.
What size of dozer is that? I can see where the D designation is but I can't really tell. Looks pretty big compared to the car. A D8 would be my guess.
Steel on steel is like rubbing two ice cubes together its not the weather.
I will give the operator credit for trying it twice but that's not a trailer for loading anything with tracks I the rain, I've got a dozer trailer with rails running front to back and on the ramps down the center to prevent sliding off, but a man uses what he has.
I know nothing of loading or moving these huge dozers but wouldn't a ramp that has something for the tracks to lock onto be helpful? I can picture a series of ridges running up the ramps that would allow the tracks to literally grab onto and keep it from sliding.
this just brings up the thought of ice cleats. i know thy would destroy the trailer but i have seen so many dozers and excavatrs stuck in stickey situations with all the guys sitting there scraching their heads wondering why the tracks are slipping. they may only be little knobs but sometimes they are the difference beteen geting your equipment out and loosing it for good.
Usually on a small road like that, yes. They generally drive ahead on small roads and behind on the highway.
The MAIN issue here is TRACTIVE EFFORT. And one way to increase it is to add weight to the dozer. So if it's 46k you have to add to that number. Your solution only takes the 46k and concentrates it in a smaller area. Coefficient of traction doesn't take into account the WIDTH of the tracks but the WEIGHT that's on the tracks and the traction available from the ground conditions.
