Building 10 MOVABLE Lego Bridges

Different movable bridges and how to build them. No counterweights, just simple structures (because Lego is strong). Enjoy!

00:10 Simple bascule bridge
00:51 Rolling bascule bridge
01:33 Drawbridge
02:24 Retractable bridge
03:13 Folding bridge
04:26 Swing bridge
05:13 Tilt bridge
05:50 Table bridge (pneumatic)
06:39 Vertical-lift bridge
07:29 Transporter bridge
08:49 ALL BRIDGES SIDE BY SIDE

Inspired by munimuni Bekkan's video and the Wikipedia article on moveable bridges:

this is a great demonstration. what I like is that you can fairly intuitively understand that these different mechanisms were invented to solve specific problems that the others don't address.

And the video just ends right there. What a work of art. No asking for subs, likes, linking videos on screen to get additional views. It just ends with all the bridges on screen labeled. This is perfection.

I just love the fact you can build an entire successful youtube channel/career off making nerdy engineering stuff out of lego. Amazing.

I have no idea why, but the sound of the car going over the bridge each time is just... lovely?

Nice to see at #10 the transporter bridge receiving a bit of love. Just a handful of them still remains, much less in operating conditions, and I live just 5 km from Bizkaia Bridge, the first one ever made and still perfectly working at 130 years old, an UNESCO heritage monument. The Eiffel tower of bridges (seriously, Alberto Palacio, the engineer, was a student on Eiffel studio).

The sound of the legos clicking together is always so soothing. 😊

This feels like a chaotic version of Poly Bridges, and I’m all here for it

I love seeing these in action. My city has a big swing bridge that lets all sorts of big and small ships pass through; seeing it on such a small scale as well is really interesting.

This is an amazing demonstration despite it being so small, he tried to make the design as compact as possible using lego as the base. This is just marvelous and an always iconic illustration of how you can put kids toys to real engineering.

The folding bridge looks the most unstable. I hope in real life, reinforcements are added so that it doesn't bend as much as this one did. Well done on this!

If there's ever a part 2, consider including the "Strauss Bascule." The most common design uses a parallelogram linkage and they are found all over Chicagoland (mostly for railroads), as well as lift bridges (7:15), Scherzers (1:21), and some old designs that are now locked in place including a Rall bridge, Page bridge, and bobtail swing bridges. There's a PDF called "Historic Chicago Railroad Bridges" that explains more about them.

Bridges are definitely one of, if not, the most interesting pice of engineering. Combining bridges with lego, and doing in a simple way like this video, is just so cool

[RCmies]

It would be cool if you did a part 2 where you recreate some of the interesting draw bridges in the Netherlands!

It's impressive how much you communicate without uttering a single word. The use of motors etc to show the mechanisms and minifigs moving on their own after building with your hands really brings the LEGO to life! Perfect video, as always.

The synchronized but at the end was a plus. Great video demonstration.

As a pro castle builder, i see them all as an absolute win.

You know its a good day when Brick Experiment drops a video

4:10 This mechanism is similar to a cars convertible roof folding back. It would be very interesting if someone implemented it into a build! Very cool video!

The only limitation to what’s possible with Lego is one’s imagination.

3:45 I am enjoying the sounds of the womb.
