Swiss Army Knife

Lego Airport Truck

With the Elves still moping at the cancelation of the Top Gear TV show we’re turning to you for Lego models to feature. This one was suggested by a reader, and it’s a bit of an odd creation. At first glance it looks like a neat, but straightforward, airport tug. It’s got Power Functions remote control of course, but then so do half of the Technic creations we feature these days. But it’s far more than meets the eye.

There are three XL motors for drive, plus another two servos for the front and rear steering. And then things start to get nuts:

There are eight pneumatic cylinders – powered by compressor – that extend stabilising jacks under the chassis. Why? Because this is also a crane. And a snow plough. And a bull-dozer.

Additional motors are used for power-take-offs (PTOs) at the front and rear, allowing a variety of different attachments to be connected using Thunderbirds-esque genius. Then there are another two pneumatic cylinders (taking the total to ten) that lift the two independent cabs up on arms so the driver/s can see over whatever it is they’ve attached to the front PTO. Oh, and twelve pairs of LED lights and another two motors for the winches.

We’re not sure that such an incredibly able vehicle exists in real life, but if it did it would probably be the only vehicle that would ever be needed. For anything. Ever. It’s all been brilliantly engineered by previous bloggee Desert752, and you can see more details of how it all works on MOCpages.

Dozer

Lego Bulldozer

Flickr’s Lego Tobi bulldozes his way onto The Lego Car Blog with this, er, bulldozer. It’s a Liebherr PR764 and it’s loaded with Power Functions goodies. You can see more via the link above.

Big Cat

Lego Caterpillar Bulldozer

This impressive remote control Caterpillar bulldozer is the work of friend of TLCB Dennis Bosman aka LegoTrucks. It features a whole host of technical wizardry and you can see all the photos on Flickr via the link, plus catch up on Dennis’ Master MOCer interview here.

Stig of the Dump

Lego Landfill Compactor

The Lego Car Blog is not a fan of landfills. They’re smelly, wasteful, and produce copious quantities of the global-warming contributor methane. However they are here to stay, at least for a while yet, so until they’re consigned to the history books man needs a way of moving all this waste about.

The answer is the awesome Landfill Compactor. Based on front-loader or bulldozer chassis these enormous machines look apocalyptically cool with massive metal spiked wheels and a huge front mounted blades. Perfect for hooning around a mountain of rubbish.

Jorge Gargia has built a brilliant tiny Technic version of a Caterpillar Landfill Compactor; it steers via centre articulation and features a raising and lowering blade by turning the exhaust stack. We think it’d make a great Technic introduction set. Certainly better than LEGO’s current one anyway. You can see all the photos of Jorge’s model on MOCpages here.

Wartime Wednesday

Lego M3A2 Half-TrackWe came down to the cage room here at The Lego Car Blog Towers to much noise this morning, where two Elves were embroiled in what may well have become a fight to the death. Meal tokens (and the occasional Smartie) are highly prized amongst our delinquent workforce, as without them they have to survive by eating the wallpaper paste left-over from the redecoration of our sumptuous boardroom. Luckily for the Elves today we’re feeling generous, so two meal tokens were distributed and we’re bringing you both of their finds.

First up (above) is a beautifully recreated M3AT Half-Track, built by Flickr’s Captain Eugene. There may be a couple of ‘Brick Arms’ pieces in there but it looks too good to ignore on a minor technicality. Today’s second creation comes from Daniel Siskind who has also recreated a World War II vehicle in mini-figure scale. His M1 Light Tractor, and those that drove them, were some of the unsung heroes of the conflict, building the ports, airfields and barracks that were needed to move and house the Allies.

You can check out both creations in further detail on Flickr via the links in the text.

Can You Dig It?

Komatsu-500w

This massive earthmover is described as a “Super Dozer” on its manufacturers website. The real-life version has a giant, 90 cubic yard blade, enough to carry all of the TLCB Elves and a few of their friends. Jorge Garcia’s Lego version is no less impressive. This yellow Technic monster contains 5 motors, a linear actuator and a plethora of pneumatics to make its functions work. All of this is covered with a realistic version of the D575’s bodywork and travels on some brilliant custom-built tracks, based on a design by mahjqa. You can dig it by clicking this link to the D575’s MOCpages listing.

Oddities

Lego Bulldozer TractorKarwik, a builder of some beautifully unusual vehicles, is back with another two for your delectation. The tractor is a Mazur D-50, an odd enough vehicle on its own, but when fitted with a cable-operated-bucket-scoop-on-rails* it becomes easily one of the most bizarre construction vehicles we’ve seen. The Elves, who are themselves a little odd, love it. See more on Flickr. (*We have no idea what it’s called!)

Next up in today’s post of unusual construction equipment is an armoured bulldozer being driven by a cat. No further explanation needed. See more at Lego Junkie‘s photostream.

Polecat

Caterpillar 963 D

D for Detail

Ah, aren’t we clever with our nationality-based titles! Tenuous link aside, this MOC is exactly what a detailed Model Team creation should be; beautifully built, superbly detailed and incredibly accurate. And on top of this it’s fully RC with Lego’s Power Functions motors hidden inside by witchcraft and magic. Makorol (is he a fish?), part of the Polish ‘LUGPol’ group, is the builder, and you can find the full gallery on Brickshelf.

8043 Motorized Excavator Review

The Technic Renaissance Continues…

This is not just a model. It IS an excavator, albeit a small one. Lego Technic appears to have arrived at the point where it’s possible to make a kit do everything the prototype does. All it lacks is its own motive power – but even this is taken care of if you have enough batteries…

First impression: Isn’t the box huge ?

Second impression: Why is it half empty ? Never mind, everything you need is here to build this hugely impressive machine. Unlike a lot of recent kits, it’s not foolproof – an expert builder will be fine with that; a novice might end up with a model that does nothing because of too many carelessly rammed together gears. Make sure each axle turns freely throughout the build and you’ll be fine. This is one to take your time over, and I for one welcome that.

So, what do all those cunningly combined gears and motors do ?

There are 4 medium motors in a module, driving the various systems through a mind-crushingly complex geartrain. These can either drive the vehicle along and rotate its body on the chassis, or manipulate the excavator arm at any of three joints according to the position of the gearbox selector. Like everything else, this is operated by remote control.

For driving it along, one might suspect the M motors would not be up to it; but their torque is surprising and it goes just fine, if rather slowly. Separate motors drive each side independently to allow it to steer. XLs with different gearing would doubtless make it faster, but since when was an excavator any kind of roadburner ?

As for the digging part, it’s very capable. Thank those linear actuators – less pure than the older pneumatics but much simpler and way more effective. There are four of them and they do a great job. Again, the gearing is quite conservative and movements are slow-ish to ensure the motors are up to it. They are, as long as the dirt is fairly loose (yes, I’ve got mine a little bit dirty – there’s just no way to resist..) It’s better still if you replace the supplied over-large bucket for a yellow one you’ve pinched from the back of a passing 8862.

The black bucket it comes with is much more suited to the B model, a handsome and useful bulldozer that’s possibly a homage to this kit’s 8275 predecessor. I do wish Lego would supply paper instructions for both models – it’s such a faff to download and it’s never the same building while staring at a computer screen.

Incidentally, have you noticed how much an 8275 will cost you now ? It’s frightening. That’s what happens to the very best models in any theme in this strange market. I just hope the price of this and other well regarded large sets isn’t driven by speculators; if so, expect it all to come crashing down any time soon… Still, when it does we’ll all still have our Lego to enjoy won’t we ?

Be that as it may, I would urge you to get this very complete model while Lego are still producing it. If you have the slightest interest in Technic, you’ll love it. 10/10.
