- Welcome to another episode of Scrap Mechanic! Today I am recreating an AVLB or an Armoured Vehicle-Launched Bridge. It is essentially a tank that carries its own deployable bridge that can be used to cross trenches or other gaps in the battlefield.

The more complicated bridge layer is designed so that it is more stealthy. With the normal one, you are having a large bridge lifting into the air, sometimes giving away their position. this one slide the bridge so that it is more inconspicuous.
It works under powerlines too
@@ThadMiller1 but you don't get any fried human T-T
Stealthy? By the time you're moving this kind of machinery into place everyone in a 20 mile radius would be able to hear you coming.
0:53 Something to note is that trenches aren’t really an obstacle for tanks. Most tanks are fast enough that they’ll skip over any kind of ditch, hole or trench they come across. And if for some reason they’re going slow enough to get caught up in one or in the unlikely event they come across a hole big enough that they can’t hop over, most tanks will have the power to brute force their way out
I think the tank isn't the main thing this was made to cross. It supposed to be laid down then allow the rest of the convoy which might not be tanks to cross.
Might I add that the first tanks were literally designed for trench crossing,
@@xdragon2k Also you have to remember tanks weren’t as fast back in those days
War Thunder Players: Are you sure?
The tank may cross the ditch with ease, but your men will probably have more trouble.
just FYI: the german slide method (which the dutch video shows) makes the bridge elements much simpler/cheaper and modular, if needed to be left behind for following units/days/retreat while the vehicle grabs another bridge for the next obstacle. Pioneer units of those armies have the same bridges which can be split ones more sideways for easy transport on trucks to be layed out by crane or to be carried for supplying the bridgelaying tanks with more bridge. No hinches and hydrolics in the bridge itself, which would need to be maintained (kept clean/lubcricated) and would be costly if left to secure a route etc..
That's actually a really good point I didn't know about. I'm wondering of the tank can angle the bridge though, or if you have a 10ft elevation on the other side of the gap if it just can't bridge that?
@Zedstein yes, it can angle it further upwards. The arm on which it slides is able to add a few degrees to what is seen in the clip and the whole tank can add a few more deegree upwards by standing higher on the frontal dozer blade. In that clip they dont max out the arm and blade.
Worst case it has to use the dozer blade to create a little ramp for itself before laying the bridge.
BUT in service all those bridges should never be laid in a noteworthy upwards or downwards angle, as friction is all what keeps them in place and a heavy vehicle moving on it could fairly easily move the bridge itself. Even when level its not advised to brake or accelerate on such a bridge because of that possibility.
I have seen a lot of different versions of these. People have made them out of many things and now finally it exists in scrap mechanic. Thank you for that.
I've seen this on call of duty modern warfare 2 and I really want to have this video
@Potato Turtle Army it’s on steam
They’ve been in scrap mechanic for a LONG time
I used to be a M60 AVLB driver, for a number of years, but when I got stationed in Fort Hood, TX, we had the M104 Wolverine HAB (Heavy Assault Bridge). The Wolverine uses the German designed bridging system, a leguan deployment system, all built on the M1A2 Abrams chassis. It isn't actually anymore complicated on the bridge side, in fact it's simpler, while the leguan deployment sytem is a beefy unit and does add complication to the vehicle side of things, but you wouldn't think it watching a skilled opporator deploy the bridge. All told it takes about 8 mins to deploy and 10 mins to recover the bridge. While some say the reason the military switched to the leguan bridging system was to make it less conspicous, it's actually because the M60 AVLB bridges were designed for lighter M48s and M60 tanks, not for M1s, thus when an Abrams had to cross a AVLB bridge it could only creap across, with the leguan bridge that same battle tank can get across at 10 Mph. Though that doesn't sound like much, when you are breaching a lane, any less time spent in a chokepoint is less time to get shot.
All told, the leguan system is a much cleaner, faster, and better built system over the old AVLB system.
If you're looking for a couple of other interesting Engineer vehicles, take a look at the M9 ACE (Not a lot of complicated engineering, and it leaks like a siv in real life), Unimog SEE truck (only us military vehicle build by Mercedes Benz. Not so much complicated, but interesting to see, no pun intended), and the PLS HEMTT (Probably pretty easy to replicate).
I would love to see episode 2 where you build an actual bridge "launcher" for extreme crossings!
Ooooh that'll be fun
They did that already a few years ago
or a working military tumbler that can launch over jumps XD
It’s actually hard to comprehend how tall these things are, a centurion Australian army bridge later (only 2 of which they made, only 1 still works) is about 9m high fully extended upwards.
I know this because I have seen it, and was told throughout about it.
as a dutch person, i can confirm we always use the unconventional method to show how inovative we are.
To be fair it did give us another province so
Scrapman do you know about the spam bots and why they're there?
Isn’t it the German Brückenpanzer Biber in the video?
True
As always, perfectly on time for my lunch break. Thanks!
Haha it’s 5 am for me

“Samir! You’re driving the tank wrong!”
“No I’m not! The tank is supposed to do this!”
3:31 making tank treads in scrap mechanic is gonna be a challenge interesting at least
A less laggy challenge would be making reduction gears with a single pair of gears with a very high reduction ratio out of survival parts only. I think a 10x10x2 (excluding the supports they're attached to) might allow for a reduction ratio of 20 or more, but the largest reduction ratio I was able to achieve was 2:1, by using the "Gear Examples" blueprint Eru has uploaded to the workshop. I was able to get higher ratios in a 10x10x3, using something similar to how old trains synchronize wheels and how pistons work, but modified for achieving a reduction ratio between a big circle and a small circle.
scrapman has made videos with the tank mod before, but to do it without mod would be too laggy
@@koktszfung No on physics 1 i have tried and they work great
Bridges also carry APV's, Artillery, Supply trucks, etc. So the bridge is for other less capable vehicles. Impressive as always..
This reminded me of the german amphibie m3, which is a heavy amphibious vehicle.
Other than deploying a bridge the vehicle itself is a bridge and it can connect to others to make the bridge longer, effectively creating a quickly deployed bridge which can cross multiple hundreds of meters but it's only meant to cross water.
Basically every form of the AVLB calls for combat engineers to level the terrain on both sides of the gap, but it's a much faster process to have that done and then have a tank lay a bridge out than it is to build a whole bridge if you've only a narrow but deep gap to cross. But this is certainly a very impressive example!
Nice build Scrapman! How about you try a Hetzer, a german tank destroyer that is basically a wedge, so it may be a good wedgegang tank XD

It would actually be interesting to see you have a multiplayer race in which everyone needs to make such a vehicle with a detachable folding bridge.
It would also be interesting to see yu make a clock powered entirely by a weight, with someone manually needing to move the weight back up. Whether you use the Geneva Drive or an Encampment (though you might want to try both, to see the differences), is irrelevant. The biggest problem I see you having is the reduction gears which would make this possible. In fact, I hope you will issue a challenge to everyone to make the most compact reduction gears with the highest reduction ratio using only blocks available in survival.
For reference, a 3x3 gear made by two layers rotated by 45 degrees, one with small pipes and one with large pipes (all of the pipes only use up 1 cube of space), can connect to a 5x5 gear made in the same way but with only small pipes, for a reduction ratio of 2:4 or 1:2 (since we 3x3 has a diameter of 3 and we remove half a block from each side because of the contact surface, we get the 2 for the diameter of rotation, and for a 5x5 we remove half from each side and get a diameter of rotation of 4, and we have the same number of gear teeth, which means the ratio of rotatio is 2:4, and if we half each number we get the ratio being 1:2). On the workshop, Eru has a blueprint called "Gear Examples", which also shows the setup in use, but that can only be used to double the speed, and it would be nice to have a single pair of reduction gears to get a much larger reduction ratio (which would also help out with the lag). I think that a reduction ratio of 20 in a 10x10x2 might be achievable with a single gear.
They've made this exact challenge in the past, but the bridge didn't fold, it wasn't a race (timed instead) and picking up the bridge was much easier (used pipe pieces to pick it up so it locked in place).
Unfortunately they have done this challenge, because I'd love to see it again
@@joshthompson8478 I liked that challenge, too! They did it with carrying a bridge which doesn't fold. Adding a folding mechanism and all kinds of difficult terrain would make this more interesting. Like one side being 45 degrees twisted when looking rom the other side, as well as different lengths of gaps, different angles for the sides (instead of parallel sides, like with the rocks which were tried in this video), and maybe even with some moving obstacles (like have one side slide, then another side move up-and-down, and another side move in a circle, and another side have coveyor-belt-like pipes pushing the bridge away, and maybe even a bridge which requires them to stop on an island and put the bridge on a different side of the island to continue).
@@riccardopetrina4212 But that is a different challenge, it's just similar, with straight bridges and only increased the distance of the gap, nothing more. Adding a folding mechanism and all kinds of difficult terrain would make this more interesting. Like one side being 45 degrees twisted when looking rom the other side, as well as different lengths of gaps, different angles for the sides (instead of parallel sides, like with the rocks which were tried in this video), and maybe even with some moving obstacles (like have one side slide, then another side move up-and-down, and another side move in a circle, and another side have coveyor-belt-like pipes pushing the bridge away, and maybe even a bridge which requires them to stop on an island and put the bridge on a different side of the island to continue).
@@SapioiT that would be pretty cool I'm just worried about time I think they only take 15 minutes to build their creations and it took him like 3 hours to make this folding one.
4:19 there you can see that you have no idea about german engineering.
The bridge layer from the US-Army (what you build in the video) because of its height its is it impractical e.g. in the forest. While the Leopard is flat on the ground with its bridge, the M60 (what you built) is already visible with its 10 meters high. So it's not impractical it's smart because of the cover.
Frankly both of them are fairly impractical. If the goal is a well fortified transport for quick bridges, both of them would be incredibly expensive only to allow the laying down of a single bridge, with a high risk of failure if they are brought through combat.
They are over complicating it, make a tank that can carry bridge pieces that are based on being light and durable (easier to do if its not designed around being able to build itself, with fewer points of failure since simplicity allows more redundancy), and protect said pieces. Then make a second smaller tank that functions like a forklift to move pieces into place. That means you can create a path through combat zones with fewer points of failure, and capable of creating more bridges with fewer vehicles.
I love this kind of scrap mechanic video: start with an idea, brainstorm, prototype, test, refine, repeat. So satisfying seeing it come together
Scrapman: why they tested on flat ground I dont know. Also Scrapman: tests it on flat ground.
Wow… What’s next? A tank that does backflips?
Edit: Apparently it’s possible to backflip with tanks sooooo…
@misyah s shut up bot
That sensor & piston trick is nice, I use it to activate different modules I weld to my tractor, not needing to rewire them.
Make one that floats some tanks had floating bridges but keep in mind it was multiple tanks for one bridge.
What time zone you in?
@@gnat8974 Philippines idk the time zone
Maybe the german Mobile bridge that folds out floaters of the top and then just drives into Position and can links to others?
@@tylanpiret95 manila timezone/EST
That a good idea for multiplayer monday where they build this together
You should try the M1150 Assault Breacher Vehicle it's the modern day version of the flail tank you did
It was in the end card of the demonstration video
@@wacky_duck1095 yeah I posted the comment before I saw it cause the bridge tank reminded me of it. Guess it was a coincidence
If you wanna keep going with the military, I recommend building a M3 Amphibious Rig. A long truck boat amphibious heavy vehicle carrier thingy
Fun fact, the maus (ww 2 german super heavy tank) crossed rivers by sealing itself and getting another maus to give it power with a cable while it drove under the river, and then repeated the process with the second one. Also, please build a calliope (Sherman with a bunch of rockets)
SC: "I like how they don't deploy it, they toss it"
They: "ok ok... 3...2...1... go! YEEET"
I'd love to see these improvements, but it would be a LOT of work for you. First improvement is to double bearing everything. Allow the stabilizer foot to extend past 90* as well as the deployment arm. Use Kan's variable piston system to allow hyper extension. For the bridge controls, have one of the pistons extend to cause the bridge to unfold, and the other to fold it in. You will run out of buttons, so I would recommend using mode switching logic so that with the flip of a switch you can go from controlling the tank to controlling the bridge with the same buttons.
i remember seeing that thing as a kid, i was absolutely in love
Hi persun
9:17 If you want right triangles in scrap mechanic, stick with 3, 4, 5 triangles. When the two sides are 3 and 4 blocks, the hypotenuse is exactly 5 blocks. You could do 6, 8, 10 too.
5:59 Armored trucks and Humvees would have a problem getting across it though.
15:00 this is the perfect ramp
Scrapman: trying to make it look legit
Also Scrapman: using a toilet seat to control the tank 🤣
Just a little fact: the bridge is for tanks but also for supplies (A tank and it’s crew can’t run for that long without it), and the trucks can’t pass most things that the tanks can
I am really satisfy when Scrapman build all of these prehistorical vehicles and they are working my mind is blown 🤯🤯🤯🤯
0:55 the first tanks were designed specifically to cross trenches and they are great at crossing deep rivers but some are too extreme
When Scrapman is crossing his bridge The other guys “we’ll just shoot your bridge while your on it”
Crossing that ditch AND retrieving the bridge was REALLY impressive! Job well done, Scrapman!
another episode of history with scrapman
Hey man :). I am a fan ever since you were just a lil channel, I'm surprised to see thay you're half a mil on subs now, Keep it going man, I'm very happy for you
11:27 the fact he remembered that part from memory impresses me
9:22 - "If I go ONE more tick..."
*proceeds to go TWO more ticks*
I imagine it works better IRL because the weight of a heavy metal bridge with a tank on top of it probably moves dirt and rock out of the way.
Impressive. Maybe a slow rotation Device for the "Fork" could be added to adjust it for more control over the Angle, when you want to pick up the Bridge.
17:48
Insults them doing it on flat grass
*proceeds to do it on flat grass*
You need to do a relay race with this tank on Multiplayer Mondays.
I used to work with the ABLV, they're absolute nightmares. Extremely slow and unreliable. we not only bridged gaps with them but also used them to breach obstacles.
To help get the pins in you could use sloped blocks around the hole to help guide it in, and preferably lowest friction possible
i was at an old army museum once and they did like a show for each vehicle there and one of them was like a similar bridge tank thing
it was really scary to look at as it lowered and deployed the bridge the sounds it made were amazing and concerning at the same time
My great uncle was one of the engineers that developed one of these for the US Army in the 50s or 60s. He also worked on the Saturn V rocket

Two lovers, forbidden from one another
A war divides their people
And a mountain divides them apart
Built a path to be together
...Yeah, and I forget the next couple of lines, but then it goes...
Secret tunnel!
Secret tunnel!
Through the mountain!
Secret, secret, secret, secret tunnel!"
Then later in the episode, Chong says "Oh I remember the last part! 'And die...'
Combine those and the lyrics are as followed:
Two lovers, forbidden from one another
A war divides their people
And a mountain divides them apart
Built a path to be together
And die...
Secret tunnel!
Secret tunnel!
Through the mountain!
Secret, secret, secret, secret tunnel!"
They got another pins on the side, that probably sits in holder in bridge to secure it during lifting/laying down(seems also offers leverage points). How they adjust height is unclear, but they got two hydraulics that give them some options. One can control angle foot is to the ground while second is controling angle of pins. Not much tho, but they are engineers, they got shovels..
I give you vehicle launched bridge 100% success.
Gonna quibble on "armored" though. The thing is made of literally cardboard.
Hey Scrapman! Awesome to see you went for my idea!
I’m gonna build the bridge out of cardboard. That’s an engineer right there
Got my Hank The Haybot sticker in the mail yesterday, thank you! All hail Hank the Haybot, always too busy getting milk for the bros. Dedicated fella
You should try to make a sailboat that stabilizes using a hiking system in Trail Makers. #48
A what system
@@brrrrrr a hiking system, it is how small boats stabilize. the crew just leans out the side of the boat to pull the center of mass to one side to stabilize the boat.
@@qwertymcenglish4825 that would be easy to implement in trailmakers
Ramirez! Get up to that destroyed bride! Follow the Wolverine!
I tried to build the Swedish version, Brobv 941, it has a completly diffrent way of deploying the bridge
@misyah s bruh
Kinda neat to see scrap man make something I help build.
A race where you have to place and pick up your bridges over chasms would seem cool.
‘This seems like the type of trench a tank could cross pretty easily’
War Thunder players: Are you sure?
Making the ends of the prongs pointed(using that one conduit connector or something) would probably help you pick the bridge back up, also removing the high friction parts in the bridge socket now that you identified the problem may help driving back away and leaving the bridge
17:00 Yup I knew that would happen. Block on block = connected. It was all welded together at the back.
Scrap man: It gets the point across. It gets the point across.
Me: No! it gets the bridge across. It gets the tank across.
Look up the M3 Amphibious Rig. The vehicle becomes a boat and connects to other ones to make a bridge than tanks and other vehicles can drive over. It’s a cool idea, and an offshoot of this idea.
18:13, balanced, as all things should be.
Always fun to see parts of my childhood come back into fashion. Thanks for the cool video Scrapman!
There was a link here showing the GI Joe toy of this tank, but I think that link might be why my comment keeps getting kicked, so I removed it.
I knew of these tanks, but I wasn't aware thet the bridge could be just picked up afterward, that's awesome xD
24:25 you could have pulled the bridge to some flat ground from the leverage bar.
You are an Engineer. Don't fool me! Your builds are always so perfect
You got to love his edits. Tell me his edits are amazing.
Love your videos Scrap Mechanist!
Maybe see about making an AI APC?
I doubt its possible, but still, throwing my idea into the hat :)
@misyah s remove yourself from my comment
As awkward as this machine is, it's still faster than building a bridge for each gap you come across.
You could do the historical tank build challenge where you pick a tank that has already been built that look like they shouldn't work (and do no research into as they did work. Makes it interesting) then put each other through challenges like a fire fight, race, obsticals, or even bridge building
Sorry for being a tank nerd but the last design you showed is a German bridge layer wich the Dutch army purchased
But yeah nice build keep up the work!!!
a clamp system might have worked easier where the expanding blocks not only clamped it but also trigger the sensors for the deployment and collapsing of the bridge. I watched the british army do a training exercise with one of these where they used it to be the base of creating a permanent bridge over a river in 1 weekend.
I think those things you recreate are literally called something like "engineering tanks" because they specialize in very specific utility tasks.
5:20
I don't think that's true, the preconnected only has pins, I believe this design has interconnecting rail that the back part slid in, giving more surface to connect
I really think the retrieval would be more doable in scrap mechanic if we had cones to alleviate the issue of the uneven terrain. Maybe try it again with The Modpack Polygons by Durf.
This should be a multi-player Monday
Being a military brat that I am I remember
seeing one of those @ 5:19 at Andrews AirForce Base in MD.
That was back in summer of 90 something during the open house air show.
I think scrap needs connectors, so you could connect parts that aren't soldered together. that would help a lot
wiring to the bridge shouldnt be an issue, it would be like connecting the hydraulic line. But if you add a few cacti to the bottom of the bridge, it should help stop it from sliding around, which could help with backing out of it.
This was pretty cool to watch
The AVLB would make a great multiplayer Monday race video
Bridge go BRRRRRRR
Bridge layers usually are used to get wheeled vehicles over obstacles. Not necessarily other tracked vehicles.
Try to make a few of the amphibious military bridges that unfold, drive into water, then connect to others to span a river
Amazing! Really elegant build, very satisfying to watch you go through the whole process, great job!!
I like the first version of the bridge dropping thanks thing
great way to get up this morning!
Multi-player Monday with Bridge tanks? Try to cross various gaps. Possibly to destroy a cardboard building then cross back? Interested to see how kan and kosmo handle it.
Scrapman: Tanks aren't good for trenches and rivers.
Me: 1st of all trenches is literally the reason why tanks were invented. And secondly a lot of tanks are specifically designed with the ability to attach snorkels so that they can cross rivers. with depth. XD
I had a gi joe toy just like this. I loved playing with it.
yes, we are very 'efficient' and handy in that area, kind regards, the Netherlands
Have not watched the whole thing so not sure what you came up with for remote controls issue but I like to use a static sensor on the "unattached" part of the creation.
On the controlled part of the creation you can use a block and piston (or bearing to move into the sensors range.
That's exactly what he did, he used a piston and an attached sensor on the bridge that, when deactivated, would unfold the bridge
Attempt #3 😂 (Original comment from Dragonfly Ornithoper video)
An air battle video like what you did with those battle drones or Cargo vs Fighter videos would be SWEET with these!
All of you guys have a dragonfly with a Canon and try to take out the one person with a parrot ornithopter/more agile ornithopter - longest flight time wins!
Cool video. this has got to be one of the weirdest tanks: Antonov A-40 the flying tank. another one is the preying mantis tank
Great video! I look forward to your videos every morning!
i would love a multiplier monday based off this concept
