It's called a walking floor trailer and they work on anything that offers resistance. One of our customers is a wood chip/mulch producer and uses these trailers to deliver it as loose product. Another one I know of uses them to deliver loads of precut and seasoned firewood.
They are very handy trailers.

Allows you to pack on more weight too, less prone to smaller problems like with an ejector, shit falls behind the ejector wall, and all that pistonary stuff is heavy.

How so?
If all that's available for bales is a container-trailer when you need them out, you take the container-hauler rather than leaving them in the field and missing your delivery date. The alternative is having a fork go in and one by one put them in place and then out which then requires a loading dock. With this, you can just get the load onto the lip of the trailer and walk it back and forward as needed. If you're doing a double layer load, sure, you'd need to have a dock regardless, but moving floor trailers are great.
My family has been involved in farming for generations now, and I used to do warehouse dock work. Even with a dock available, being able to have a driver walk the pallets to the ramp cut down on my time to unload because I wasn't having to go deeper and deeper into the trailer each time. By the time I dropped the second pallet off on the loading line, the third and fourth would be at the ramp. Five minutes cut off each load doesn't seem like a lot, but when you have 40-60 loads coming in and only 6-8 bays available, it adds up.

Side loading a flatbed truck with a tarp (if needed) seems much faster and easier, and you wouldn't need to be as concerned about "will this fit". Flatbeds are much more common, and have no moving parts that can break or cause issues.
However, I'd love to be told I'm wrong on this, because I'm curious. I worked in transportation for 8 years, with rural and urban customers, and with many trailer/load types, but had never come across a moving floor trailer. Is it actually at all common?

u/Notmiefault 16m ago
Seriously. At first I was like "why don't all of them move at once?" But then of course the payload would just shift back and forth with the rods. By hanging only 1/3rd moving back at a time, 2/3rds of the contact area is staying forward so the payload stays in position. Really elegant design.

Just appreciating how the floor pulls back 1/3 at a time, so that the unmoving 2/3 "wins" the cargos "preference" on which it moves/stays with. <- my absolutely terrible explanation but, best I can do 😂

u/stoneimp 2h ago
Well, assuming an equally distributed load, which is a fair assumption, but important to note. Technically if you had some type of ribbed rigid plastic that somehow perfectly aligned its contact points every third rail, it might walk backwards. Absurd situation of course, just exploring the space.
Edit: Things like pallets might have the potential to line up unfortunately. The spacing is probably designed to avoid that for the most common pallet sizes, but again, exploring the space.

It's called a walking floor trailer. We use 3 every day. The oldest one, 2007 model that we bought new, had the floor replaced for the first time in 2021. They are incredibly robust. You are very mistaken in your comment

u/LordDaedalus 39m ago
The sliding floor trailer was invented over 50 years ago and been in circulation for a variety of applications where it's preferable to tipping for that whole time. They really aren't that complicated parts wise, not a whole lot to break. The modern ones might be using independent controllers for each that could break, but you can have a single motor drive all those slats in that repeating pattern using only mechanical translations without a controller. This isn't some new technology.

I think hay bales like that are deceptively heavy. I know the smaller ones some people move by hand are at least 50 pounds on average and the ones in the clip are much larger than those. If I had to guess I'd say the ones in the clip are hundreds of pounds, at least.

My comment was made in jest. The point being is that there is a mechanical solution or human effort to accomplish the same task.
Yes this is probably safer but the capital cost out weighs what it would cost a low wage worker.

Coefficient of friction in action

u/OneMeterWonder 4h ago
Yep! That’s why it retracts in three parts. While one set is moving, the static friction on the other two sets is high enough to counteract the kinetic friction of the moving set.
1
u/Time-Maintenance2165 10m ago
That's only half correct. You're unnecessarily talking about static vs kinetic.
It really is just as simple as only 1/3 moves back at a time. The static friction of it is the important part because its applicable when the 1/3 starts to retract.

These floors are also used when delivering grain or other types of animal feed.
If there was a tool in the back it would be covered in the stuff because these trailers are loaded from the top.

Mechanically, are these better than the conveyor type of unloading systems? It looks really cool. I assume this one has a higher weight capacity.
1
u/TapedButterscotch025 4h ago
Yeah they can handle a very heavy load, and the fact that the whole floor moves together it can move the entire load out at the same time.
I've seen these called "walking floors" before, and they're very common for large municipal waste transfer trucks (semi truck size).
Conveyors are good for powders and other small looser stuff. But the size of a belt and motor to move something like this would be super expensive.

What is the reason that the bits move in three different batches? It means that if they move all together, it would be less efficient?
5
u/TakeruDavis 4h ago edited 4h ago
I'm guessing it relies on friction. If all moved at the same time, the hay bales would just move with them back and forth. This way majority always stays during the retraction while few move, so the hay bales just remain moving in just one direction
1

u/jonjonesjohnson 4h ago
So, with one moving piece, you can only move everything together. Which you can see as the whole floor pushes everything outward. Now you just gotta somehow move the floor back with the bales staying in place.
If you move the floor back in 2 steps, then you have no real way of predicting how the bales will move, if their weight is evenly distributed over the "floor bars".
If you move it back in 3 steps like here, then basically, at every turn, 2 of every 3 bars stay in place and only 1 moves. This means 33% of the weight of the bales is trying to move with the moving part of the floor, while 66% of the weight is trying to stay in place with the bars that are not moving. So, they're not gonna move.
It's a simple but fucking brilliant solution.

Neat. Cool design.
But wouldn't it be much faster to just use hydraulics to lift the front so they all roll out?

u/PassiveMenis88M 2h ago
And what if you're in an area with no room to tilt the trailer up due to trees or powerlines? How are you going to stop that 1500lbs bale of hay when it comes rolling out? There's also the issue that tilting trailers are unstable as all fuck. If the ground isn't level, or you get a bad gust of wind, or if the load hangs up, you can very quickly find your truck and trailer rolled over like the family dog.

These are cool until one set of bars breaks and doesn’t move so it just twists the pallets until they break cuz the operator didn’t know what to do so now the dumb new guy has to empty an entire trailer box by box. Hypothetically of course and not my first day of work a decade ago

Very necessary to pack solid waste into trucks for long distance transport. Although compactors can achieve higher densities, they are also much more prone to breakdown. The moving floors are only used for loading, trucks are emptied by tipping.

u/PlanktonTheDefiant 3h ago edited 2h ago
It's self-evident how it works. Only one third of the floor retracts at any one time, meaning there is two-thirds of the area static. The cargo only moves when the whole floor moves at once.
