"Long Haul"

So you look at the first picture and you think "cool, a dump truck". It reminds me of my big Tonka when I was a kid, and seems like it would be right at home with other LEGO City sets. Then you get to the second picture and get your mind blown, this baby transforms! Builder Cpt. Brick not only nailed the City look, he nailed the Transformers look. As awesome as it is though, I think my favorite thing about these shots is the minifigs casually enjoying coffee in the shadow of the robot.

Euclid R-170

I've always wanted to see one of these man-made wonders in person, there's just not that much heavy mining on the central coast of California (but you know, I'm fine with that too). It's just staggering to me that we can make such colossal machines, and that they work. It's also staggering to me that we can build such colossal recreations of these machines in brick, as builder Beat Felber has done here. Not only is it big, beautiful and beefy, it's remote controlled with S-Brick and Power Functions. And check out those custom wheels!

Franken

I love a MOC that instantly conjures visions of scenes and scenarios. The moment I saw this construction mech by Moko, I saw teams of identical mechs busy at work constructing a futuristic building. Each one dutifully going about it's workday lifting, welding, fastening and moving. What a wonderful sight that would be.

John Deere 75G

At first glance this looked like one of those behemoth large machinery MOCs, but take a closer look, it's a surprisingly small large machinery MOC. This John Deere 75G by LegoMathijs is so packed with detail and accurate that you just can't tell how big it is when you first look at it, and I think that in itself is a testament to it's quality. Factor in all the cool little touches like opening panels, detailed engine and decked out interior, and you've got a winning MOC.

Colossal Northwest Crane

I don't know much about large construction vehicles, but I can certainly appreciate when I pass one on the road. Colossal machines that in turn build colossal things just sort of blow my mind. And LEGO versions of these vehicles, especially built on the scale of this crane by builder LiftingBricks, are just as mind blowing. This thing is technically a work in progress, but so cool I just had to share. Click through for more details and tons more pics.

Volvo EW205D

Builder davekuhh is back with another gigantic and insanely detailed piece of heavy machinery. This time it's a Volvo excavator, and it's a beauty. At first glance it's really hard to judge the scale of this thing, but after you peruse the pics (and there's plenty more if you click through) you can start to get an idea of it. It's too bad the ones in real life don't stay this clean, it's actually a really slick design.

Moving Earth

I nearly scrolled right past this mind-boggling MOC by davekuhh. It's not that I have anything against construction equipment or Catepillar, there's just so many of them. But then I noticed an unusual amount of detail, and I was curious what the "sand" was that it was moving. Turns out this thing is absolutely colossal, and that "sand" is a mix of 1x1 and 2x2 tiles! You'll have to click through to truly appreciate this beast, it's over three feet long and really needs to be seen at high resolution.

AP 35-T Cargo Lifter

Say you had to maneuver a 40,000 pound cargo container of cat litter, and while you were at it, 17 cases of vienna sausages, 9 cylinders of helium and a couple 50 gallon drums of lubricant (what can I say, it's gonna be a wild party). Normally you'd have a hard time with this, but not of you have access to a AP 35-T! Lego Junkie brings us this heavy lifting wonder (speaking of wonder, didn't that guy just do Iron Builder, sheesh) More pics and a full back story on MocPages.

That's A Big Crane

It's positively colossal! This minifig scale Liebherr crane took builder [maks] over six months to build, and I can believe it. At over 27" long and weighing in at over 4 pounds, it's the biggest mini fig scale vehicle I've ever seen. I would love to see this monster in person.
