The Overburden Conveyor Bridge F60, used in open mines. It looks pretty huge here, sure, but how big is it?

A fair bit longer than the Eiffel Tower laid flat, is how big. [DarkRoasted Blend]

The Komatsu 9xx Series mining trucks look a bit like Tonka toys. No, they look exactly like Tonka toys. [MiningTopNews]


24-foot-tall Tonka toys, mind you. []

Howard Hughes' ill-conceived, ill-fated Spruce Goose has always been fascinating to me. HAY GUYS, LET'S MAKE A PLANE OUT OF WOOD! WHAT COULD GO WRONG? [Colorado U]


Along with being a hugely strange idea, it was hugely huge. That's the 1019-ft Queen Mary cruise ship, for reference. [DriveArchive]

The Bagger 288 strip-mining machine has gained plenty of notoriety on the internet, mainly on account of looking like it was designed to kill. It isn't, at all, but you can't fault us for jumping to conclusions. Look at it! [DRB]

The general public's unease about this horror machine won't be helped by the fact that it's large enough to saw large ships in half, and gobble up a bulldozer without so much as flinching. [Wikimedia]

Old Soviet military hardware is incredibly interesting—a vestige of a time when both of the world's superpowers applied their distinctively different philosophies to a race to design some of the most ridiculous machines ever created. But surely this photo of a Typhoon Class submarine is just the victim of some zoom lens distortion, right? [DGIBNET]

Ha ha, not at all. Those there are humans, see? []

The Space Shuttle Conveyor is a literally-named, track-driven machine that you've probably seen before, saddled with one of NASA's various, now-dormant spacecraft. But it's hard to even judge how big the shuttle is, much less its ride. [NASA]

As you probably guessed, it's inconceivably gigantic.

The B-2 Bomber is another familiar piece of hardware, but one that is usually pictured without comparison, flying through the air, looking secretive. It's a stealth plane, and it's shaped like a Styrofoam glider, so I always imagined it as fairly lithe. []

It's actually startlingly large, with a wingspan of over 172ft. [OklahomaCity on Flickr]

Anyone with knowledge of power generation can tell you that it's no wimpy windmill that can pump out six megawatts of power, and that this windmill must be fairly substantial.

Whether they'll be able to find the words to fully describe how substantial it is is another matter entirely. Those orange specks peeking out of the fan's face like insects? Those are maintenance workers. [Giz]

At first glance the Knock Nevis supertanker, with its weird name and goofy-large "No Smoking" sign below the officer's deck, looks like your average cargo ship: Pretty big, pretty flat and and pretty boring. [Wikimedia]

Far from it: The largest ship in the world, measuring in at over 1,500 feet long, ole' Nevis is a floating city. [DamnCoolPics]

The Mil Mi-26 is one of the classic sense-of-scale killers, since its proportions are almost exactly like a regular helicopter, just bigger. How much bigger? [Wikimedia]

That little black thing hanging from the Mi-26's hook there is a Chinook, which is nearly a hundred feet long. [Aerospaceweb]
