Lego Teddy Bear Mech

This is a teddy bear-controlled mech, because… well, do you need a better reason? Priovit70 owns the mind that’s equipping stuffed carnivoran mammals with walking robots, and this one is apparently a Cabearpillar Power Loader B-948X prototype. Whatever, there’s more to see of this bear-in-a-mech-suit at Priovit’s photostream via the link above!

Big Dump

Lego Caterpillar 797F Mining Truck

It’s tough being a TLCB Elf at times. After being squashed on several occasions by colleagues’ remote control finds one of the Elves finally got itself an RC model to exact some revenge and then found it was too slow to do any squashing at all. Worse still, its targets jumped in the back for a free ride.

Fortunately this amazing Caterpillar 797F mining truck (one of the largest in the world in fact) by Sheo features more than just remotely controlled drive and steering. All-wheel suspension and folding ladders are present too, but they’re of no use to a vengeful Elf.

What was useful was the enormous fully mechanised dumping bucket, operable remotely via twin linear actuators. This meant the inventive Elf could drive its free-riding colleagues out into the snow that’s currently surrounding TLCB Towers and tip them neatly into a snow drift. Revenge exacted.

We now have one very happy Elf, and several very cold ones. No matter, there’s more to see of Sheo’s excellent Caterpillar 797F on Flickr and at the Eurobricks forum, which includes a video demonstrating the model’s features. Click the links to take a dump.

Dig Big

Lego Caterpillar 7495 HF Bucket Excavator

This stupendous vehicle is a Caterpillar 7495 HF electric rope shovel and it can carry 120 tons up to 9m high in its ‘dipper’ (or bucket to you and us). Well this one can’t obviously, as it’s made from Danish plastic, but it’s rather impressive all the same.

Built by previous bloggee Arjan Oude Kotte (aka Konajra) it is – almost unbelievably – mini-figure scale, and features a full array of LED lighting, Power Functions remote control, spectacular detailing, plus of course, a truly enormous shovel.

An evolution of Arjan’s original model that appeared here in 2014 there’s more to see of this brick-built masterpiece at his Caterpillar 7495 HF photo album – click the link above if you’re diggin’ this as much as we are.

Cat’s Claw

Lego CAT 434E Remote Control Backhoe

Digging cats. It normally means they’re doing something horrible in your garden. Not today though, because this CAT 434E backhoe is something rather wonderful.

Built by Zbiczasty of Brickshelf it’s near a perfect functioning replica of Caterpillar’s real 4×4 backhoe, complete with no less than fourteen working functions.

The all-wheel-drive is remotely controlled, including remotely operable pneumatic differential locks, pendular front suspension, and three steering modes (front, all, and crab), exactly as per LEGO’s own brilliant 42054 Claas Xerion 5000 tractor set.

Of course there’s a working front loader – also powered by remotely controlled pneumatics – with both bucket and boom movement, and a fiendishly complicated pneumatic backhoe with five different movements from elevation to slewing.

Finally there are pneumatic stabiliser legs mounted at the rear and a suite of LED lights. It’s a remarkable machine and one of the most realistically engineered Lego creations that we’ve ever come across.

There’s a whole lot more to see of Zbiczasty’s Caterpillar 434E backhoe at the Brickshelf gallery via the link above, but the only way to really appreciate how well this model works is to watch it in action – check out the video below to see just how good it is.

Tipping Obligatory

Our Elven workforce couldn’t resist this nicely detailed mining lorry from Flickr’s LEGO 7. As well the detailing, the “Giant Dump Truck” has some nice play features, including an opening cab & tipping function.  Depending on how you choose to read its name, it could also be a bit rude. Perfect for our Elves and sadly perfect for us too.  Click the link in the text for more photos.

Big Bucket

Lego Technic CAT 6120B Hfs Mining Shovel

Just like your Mom, this fully remote controlled Technic Caterpillar 6120B HFS mining shovel is absolutely massive.

Designed and constructed by Technic-building legend Shineyu, this brick-built behemoth weighs nearly 15kgs, replicating perfectly  in Technic-figure scale the largest hydraulic mining shovel ever made.

Lego Technic Caterpillar 6120B Mining Shovel RC

With nine Power Functions motors driving the Caterpillar’s tracks, turntable, shovel action and bucket opening there’s some serious engineering at play, and without a single non-LEGO piece being used anywhere in the build Shinyu‘s creation really shows how far LEGO-building can be taken.

An extensive gallery of images is available to view, and just like your Mom there’s an easily accessible video of the 6120B in action too. Click the link above to jump to the Eurobricks discussion forum for the full story.

Big Cat’s Back

Lego Caterpillar D11t Remote Control Bulldozer

Davy Linden’s incredible (and enormous) Caterpillar D11t bulldozer was featured here at TLCB last year, and if you thought it couldn’t get any more amazing, it just has!

Previously a static display piece, Davy has since added two Power Functions XL motors (one for each track), a pneumatic compressor powered by an L motor, and four Servo motor powered pneumatic switches to control a range of working functions, including the huge front blade’s height and title angle, and the operation of the rear ripper. There are two SBrick’s enabling bluetooth control via a mobile device as well as full LED lighting.

There’s lots more to see at Davy’s photostream – click here to make the jump to Flickr.

Cat’s Claw – Picture Special

Lego Technic Caterpillar 390F

TLCB favourite shineyu is back, and for his latest build he’s built big. This spectacular creation is a fully working replica of the Caterpillar 390F, and it’s absolutely packed with stunning engineering.

Inside the lifelike bodywork are a range of Power Functions motors and infrared receivers that allow the complete remote control of all of the Caterpillar’s functions.

Lego Technic Remote Control Caterpillar 390F

These include independent drive to each track with skid-steering, a motorised turntable enabling the rotation of the superstructure, and a powered on-board compressor.

Able to generate its own air pressure shineyu’s Caterpillar uses LEGO’s pneumatic system to control the boom arm’s elevation and extension, as well as the movement of the grab/claw-type thingumy mounted on the end (if you know what this is actually called let us know in the comments!).

Lego Technic Remote Control Caterpillar 390F

With four small pneumatic cylinders the claw is powerful enough to lift a variety of fruits (lemon pictured above), or – if your a TLCB Elf – grab your head really very tightly indeed and then drop you in the food recycling bin. It was strictly in the name of research…

Anyway, whilst we explore the multitude of ways in which this incredible creation can be put to use terrorising our slovenly workforce you can check out all of the top-quality images via the discussion on the Eurobricks forum – click here to join in.

Big Cat – Picture Special

Lego Caterpillar D11t Bulldozer

This incredible replica of Caterpillar’s D11t bulldozer was uncovered on Flickr. The builder is Davy Linden, and his spectacular creation is one of the finest vehicles we’ve posted in 2015.

Lego Caterpillar Bulldozer

Measuring almost a meter long and with brick-built tracks containing around 3,000 individual pieces Davy’s model is one of the largest and most intricate builds in TLCB history. There’s an extensive gallery of high quality images available to view on Flickr – click the link above to join us there.

Lego Technic Caterpillar Dump Truck

Today a jubilant TLCB Elf set a new office record; the most colleagues squished in one event since records began. It seems that whenever an Elf finds a monster remote controlled creation its first instinct is to flatten as many of its co-workers as possible with it. One poor Elf was so ingrained into the tyre tread it was rotating with the wheel to be newly squashed every few seconds.

The tyres in question are third-party RC items, employed here because The LEGO Group simply doesn’t make any large enough. The rest of this creation is 100% authentic Lego though. It’s based on a Caterpillar 795F heavy dump truck – as found in open-cast mines all around the world – and it’s powered by two XL motors, with a further motor controlling the steering and another the lifting of the bucket.

If you’d like to see all of the images then head over to Eurobricks where builder shineyu has started a discussion topic to showcase his work. If you like this creation you might also be interested in an incredible previously blogged Terex excavator that works alongside the 795F in the real world; it’s now available on MOCpages to view, whilst we spend some time giving some lightly injured Elves a ride in the bucket of the Caterpillar.

Tiny Technic Tracked Tipper

Lego Technic Catterpillar

The smallest official LEGO Technic sets in recent years have a been a bit, er… rubbish. But all that could change with Rabbitdesign’s tiny tracked tipper. Based on one of the Caterpillar Company’s more unusual vehicles, Rabbitdesign’s Technic version features working tracks and a tipping load bed via a worm gear. You can see more on MOCpages, and you can vote to turn this model into an official LEGO set via the newly re-launched LEGO Ideas website (formally LEGO Cuusoo).

Lego Cat Tractor

This tiny Technic Cat tractor was discovered on the creation-sharing image library Brickshelf. Despite its diminutive size this Cat is fully remote controlled, it’s even small enough for us to let the Elves have a go without fear of one of them getting smushed. Jorgeopesi is the builder and you can see the full gallery of his creation by clicking here.

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.

Big Bucket

Lego Technic Cat Excavator

This enormous Caterpillar 7495 HF bucket excavator was uncovered by a group of very excitable Elves on Flickr (a few weeks ago actually, when it wasn’t quite finished, so this is an updated post). It’s the work of LEGO-building genius Konajra, a man who’s featured here on TLCB a few times in the past with his incredible ships and Town scenes, and he’s now added technical-brilliance to his already expansive building skill-set.

Contained inside the Caterpillar’s wonderfully realistic body is an extensive range of Power Functions components which are used to control all the major aspects of the excavator’s movements. The Elves thought this functionality was great fun (at least the ones at the controls did), but with several of their colleagues smushed into the office carpet and others deposited on high shelves from which they had no hope of descending, the controls were swiftly taken away and returned to Konajra.

You can see more details of the Caterpillar, including an insightful ‘naked chassis’ shot by clicking the link to Flickr above.

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.
