Mighty Mercedes

Lego Technic Mercedes-Benz Zetros Truck RC

This stunning looking Mercedes-Benz Zetros 6×6 crane truck is the work of newcomer JRX, and it’s might just be the most technology and feature packed model of the year so far.

Underneath the realistic exterior are fourteen Power Functions motors, fifteen pneumatic cylinders and ten pairs of LED lights. Oh, and a third-party BuWizz brick to provide the power required and control the working functions. Now concentrate, here comes the science part…

Lego Technic Mercedes Zetros 6x6

All six wheels of JRX’s Zetros are independently suspended and powered by four LEGO Buggy Motors, with the three differential locks activated by a Servo motor and four pneumatic cylinders. These pneumatics are powered by an on-board compressor consisting of a Large motor and four pneumatic pumps, which also drive the crane extension and boom lift via a further five pneumatic cylinders.

A Medium motor and a further three Servo motors power the crane winch, rotation and elevation, whilst another Servo, Medium motor and two more pneumatic cylinders drive the outriggers. One final Medium motor powers the front winch and ten pairs of LEDs light the headlights, tail-lights, floodlights, warning lights and flashing turn signals.

JRX’s Mercedes-Benz Zetros has more squeezed inside it than your Mom’s corset, and just like your Mom there’s a video of it action available to view online. You can watch the Zeros is action via the video below, and you can see all of the photos and read further build information at both JRX’s Flickr photostream and via the Eurobricks discussion forum.

Trucavator

Lego Technic Tatra Truck Excavator

We don’t see this type of vehicle in TLCB’s home nation, and we’re not really sure why. A hybrid of truck and excavator it seems like quite a useful design, being fast enough to drive on roads without annoying everyone and diggery enough to do some digging when it reaches its destination.

This pneumatically-powered Technic version is based on a Tatra 815 with a UDS excavator mounted to the rear. It’s been built by newcomer Ivan MOC and it features working steering, a V4 piston engine, suspension on all axles, pneumatic stabilisers and boom elevation, manual boom extension and 360° excavator rotation.

There’s more of Ivan’s build to see at Eurobricks and Flickr – click the links if you dig it.

Candy Crush

Lego Technic Volvo FMX 4x4 Crawler RC

It’s been a slow (read ‘hungry’) week for The Lego Car Blog Elves. However, with their empty stomachs ‘motivating’ them it was only a matter of time before we’d have a creation to share with you.

The hungry Elf responsible for today’s find was duly awarded a meal token and Smartie, upon which something remarkable happened… the Elf ate about half of its Smartie, and it then proceeded to break the rest into pieces. Were we about to witness the first ever moment of Elven compassion and sharing? Were we balls.

The aforementioned Elf scattered the Smartie pieces opposite a curtain in the office and then scurried off. Soon several of its colleagues had sniffed out the unguarded confectionary and landed on the abandoned loot like seagulls on an open bin.

But unguarded the confectionary wasn’t, and the curtains suddenly parted as a huge white truck powered through them. The nearest Elf had just enough time to point and scream before being squashed forcefully into the office carpet, before its scavenging colleagues met the same fate.

A jubilant Elf then re-emerged, scooped up the Smartie remnants, and ran off cackling madly. Sigh. We thought they were getting bored of this.

Still, kudos the Elf in question, which had deployed some remarkable inventiveness to overcome its find’s lack of speed – which normally would have left it unable meet out any smushings.

The vehicular weapon, whilst slow, is a mighty impressive bit of kit though. Based on a Volvo FMX truck, the build features five Power Functions motors that power the four-wheel-drive system, generate air pressure for pneumatically locking differentials, and drive the centrally-pivoted steering, whilst pendular suspension with simply ludicrous articulation and oversize tyres from the 42054 Claas Xerion tractor set take care of truck’s impressive rock-crawling ability.

The build is the work of TLCB debutant dgustafsson1317 and there’s an enormous gallery of high quality images available to view on Flickr. Click the link above to see all of the Volvo FMX Crawler photos, whilst we scrape some very flat Elves out of the office carpet.

Pneumatic Crane Truck – Picture Special

Lego Technic Pneumatic Crane Truck

After a series of small creations we’re back with something big. Really big. Measuring almost a meter long, weighing over 8KGs, and constructed from around 8,000 LEGO pieces, Lucio Switch’s astonishing remote control and pneumatically-powered crane truck is one of the most complex creations that this site has published.

With seventeen Power Functions motors, eighteen pneumatic pumps / cylinders, and six switches, Lucio’s truck takes Technic construction to the limit of what is possible with Danish plastic. Four XL motors drive the rear wheels which are suspended on live axles, whilst the two front axles are steered by twin Servo motors and are suspended independently (which makes for no less than twenty-four shock absorbers in all!).

Lego Technic Remote Control Truck

Underneath the fully suspended and tilting cab (with a working steering wheel, suspended seats and an opening engine cover) is a working V8 piston engine, with twin LiPo batteries that power the motors and six sets of LED lights hidden within the chassis.

Nine M and two L motors then drive everything from the front and rear stabilisers, crane rotation, winch, and the pneumatic pumps which provide air pressure for the three-stage crane elevation and extension mechanism, all of which are controlled via four IR receivers through an SBrick bluetooth device.

Lego Technic Pneumatic RC Crane

Fortunately for us here in TLCB office that lot is much too complicated for our Elves to figure out, so Lucio’s incredible truck was unable to cause carnage and mayhem. It is however absolutely worth checking out, either at Lucio’s Flickr photostream or via the Eurobricks discussion forum, plus you can watch the truck in action via the video below. Prepare to be amazed!…

Two Technic Tractors Tuesday

Lego Technic Case 620 HD Tractor

Today’s blog post is brought to you by the letter ‘T’. Plus the Elves are learning about alliteration, which means that we have not one but two Technic tractors to show you.

They’re both remote control too, which also meant that we had something of an Elven showdown in the corridor this morning. Unable to squash any of their colleagues due to their finds herculean slowness, each Elf decided that the next best route to carnage was to turn their respective machines on one another. Cue the slowest vehicular joust in history, at the end of which the tractors calmly bumped into one another and the Elves at the controls left in disgust.

Well they may not be impressed, but we are, as each build is a masterclass in Technic engineering. Above is newcomer Brick_Sticker’s enormous Case 620 HD, driven by an XL motor and featuring an unusual (but very clever) pneumatic articulated steering mechanism, with an on-board compressor powered by a Medium motor providing the air pressure. Another Medium motor drives a power-take-off, and there are four pneumatic lines where tools could be attached.

It’s a spectacular machine and well worth your click – you can check out all the images and details via both Eurobricks and Brickshelf.

The Case’s gladiatorial opponent in the corridor joust comes from previous bloggee Damian Plesniak, and if anything it’s even slower. Driven by twin Medium motors, Damian’s tracked mini loader features skid-steering, plus a tilting and raising bucket powered by a third Medium motor and an XL.

It works a treat too, and you can see all of the (brilliantly taken) images on Flickr here, plus you can watch a video of the loader in action by visiting the Eurobricks discussion forum.

Big Forker

Lego Valmet TD 28-12 Forklift Truck

This blue behemoth is a Valmet TD 28-12 heavy-duty forklift, and it comes from probably the biggest company you’ve never heard of. Trading for over 200 years, Valmet are a Finnish manufacturer of, well… pretty much anything. Trains, trams, clocks, weaponry, aircraft, paper mills, cars, sauna thermometers, and – as here – tractors, are just some of the various products that the company has produced at one time or another. This huge forklift comes from Flickr’s Havoc, and it’s a fully operational engineering marvel. Forgoing the usual Power Functions motors, Havoc’s creation utilises pneumatics to power the forklift tilt, elevation and even variable fork-span. There are also working LED lights and Hand-of-God steering, and there’s more to see of this impressive machine on Flickr via the link above.

Big Yella

Lego Marathon LeTourneau L-1200 LeTro-Loader

This absolutely enormous contraption is a fully working 1:28 scale Lego replica of a Marathon LeTourneau L-1200 LeTro-Loader. Built by Beat Felber of Flickr this amazing creation all the functions of the real LeTourneau, a machine built to load 170-ton mining trucks with just a few scoops of its 22-cubic-yard bucket.

Beat’s Lego recreation of the L-1200 includes that huge bucket, controlled by two four-cylinder pneumatic pumps each powered by a Power Functions L motor and a Servo-actuated valve. Two more motors drive all four wheels via in-wheel planetary gear reduction, and the articulated steering is taken care of by a fifth electric motor, all of which is controlled remotely via three Power Functions receivers.

All in it’s an incredible feat of engineering and there’s more to see at Beat’s photostream – check it out via the link above if you did this build as much as we do.

Swirly

Lego Liebherr LH60 Timber

Splosh. [Elven screaming]. Splosh… Hmm… that doesn’t sound good. One weary walk down the corridor here at TLCB Towers later and the source of the disturbance was found. It’s been a while since an Elf brought back a remote control find to wreak havoc, but today old habits were resumed and havoc was indeed being wreaked.

This culprit was at the controls of this, gkurkowski of Brickshelf’s enormous fully functioning Leinherr LH60 timber grab. Despite featuring a beautifully engineered remote control all-wheel drive and steering system, the Liebherr was much too slow to run down and squash any Elves. Luckily for the pilot however, gkurkowski’s LH60 model also includes a remotely controlled rotating superstructure, two-peice pneumatic boom extension and a working grab, and it’s these features it choose to deploy.

Held aloft by its ears, an Elf was being repeatedly dunked in a toilet, in a manner similar to that used by public school bullies. Funny as this may have been, the Elves are not allowed in the TLCB Executive Washroom and Sauna so we had to put a stop to it. The very glum-looking victim is now sitting atop a radiator to dry out, whilst the victor has escaped with a yellow Smartie, and we’re left to have a go with the Liebherr ourselves.

Whilst we do that (for research) you can see loads more of the build, including some interesting work-in-progress shots, on Brickshelf – grab a look via the link above.

Pagani Huayra – Picture Special

Lego Technic Pagani Huayra Sariel

It’s time for something special. Really special. Poland’s Paul Kmiec, better known as Sariel, has been wowing the online Lego community for years. He’s a published Lego author and a veteran of this site, with a huge range of diverse Technic machinery published here over the years. His latest creation, in construction for months, reached TLCB yesterday, and we may only be a few weeks in but 2017 will have to be a pretty incredible year to beat it. This is Sariel’s fully remote controlled Technic Pagani Huayra…

Lego Technic Pagani Huayra Sariel

Built in 1:8 scale Sariel’s Huayra is a perfect Technic replica of the ultra-rare Italian hypercar. The bodywork, constructed from LEGO’s Technic panels, flex tubing and lift-arms, is a work of art, but it’s what’s underneath it that is truly remarkable.

Lego Technic Pagani Huayra Sariel

A remote control drive train, controlled by a third-party SBrick bluetooth module, powers the Huayra, with a remotely operable two-speed gearbox and fully independent adjustable suspension included too. There are opening doors, and functioning turn signals, reversing and brake lights – all engaged automatically when the Huayra turns, reverses or decelerates.

Lego Technic Pagani Huayra Sariel

Yes, decelerates – because Sariel’s Pagani features remotely operated working pneumatic brakes and the Huayra’s trick active aerodynamics, including the front and rear spoilers deployed on each side when cornering and the rear-mounted airbrake used during heavy deceleration.

The whole set-up is a delight to watch and you can do so via the beautifully shot video below, plus you can see the full gallery of exquisite imagery via Sariel’s photostream – click here to view one of the finest Technic Supercars ever built.

Whatta MAN…

Lego MAN TGX Truck

…whatta man, whatta man, whatta man, what a mighty good man. Sorry about that. Anyhoo, this is a mighty good MAN, built by Beat Felber of Flickr, and featuring remotely controlled 8×6 drive, steering on the first and second axles, motorised trailer coupling, working headlights and warning beacons, opening doors and hood, and a pneumatically tilting cab.

Lego MAN TGX Truck

It’s a spectacular creation, and it looks absolutely stunning on the outside too (and orange isn’t an easy thing to pull off if you’re a man). There’s lots more of this incredible creation to see at Beat’s photostream – click the link above to make the jump to the full gallery and technical details.

Miniature Minecraft

Lego Technic Mining Loader

We were a bit underwhelmed by LEGO’s 42049 Technic Mine Loader set when we previewed it here towards the end of last year. It has pneumatics and a two cylinder engine, but…meh. However a recent upload by previous bloggee Tamas Juhasz (aka mbmc137) shows how it should have been done, and at about half the scale.

Tamas’ tiny Technic recreation of the official set might be small, but it packs in just as much functionality, and in doing so it might just be the neatest and most well engineered small-scale Technic model we’ve seen this year. It could even be a set, if there wasn’t one already…

Lego Technic Mining Loader

With all the functionality of 42049, Tamas’ build squeezes in all-wheel-drive, articulated steering, pneumatic bucket elevation and tilt, and a two-cylinder piston engine (making it just as unrealistically underpowered as LEGO’s version).

There’s lots more to see of this incredibly tidy build at Tamas’ Brickshelf gallery and at the Eurobricks discussion forum, plus there’s a video of the loader’s features available below.

Pneumatic Backhoe – Picture Special

Lego Technic Pneumatic Backhoe Loader

This magnificent pneumatic Technic backhoe comes from TLCB favourite Máté Lipkovics aka Lipko, and it’s one of the best pieces of Lego engineering you’ll see this year.

Lego Technic Pneumatic Backhoe Loader

A Power Functions motor operates duel pneumatic pumps, allowing Lipko’s model to run two sets of pneumatic functions simultaneously. These include the backhoe; which can rotate, elevate and tip the bucker, the front loader; which both elevates and tips, and the rear-mounted stabilisers.

Lego Technic Backhoe

If that wasn’t enough there are mechanical functions too, including all-wheel-steering, both by Hand-of-God and the steering wheel, pendular suspension, an opening hood and a rotating driver’s seat.

Elf Wash

Lego Technic Excavator Grabber

Well we’ve found our favourite creation of the week so far… This excellent-looking Technic tracked excavator comes from previous bloggee Horcik Designs, and it’s a thoroughly wonderful machine. Wonderful because it has no less than three pneumatic cylinders providing movement to its arm and grab. Wonderful because those cylinders are fed air by a Power Functions driven electric pump. And mostly wonderful because it can pick up a TLCB Elf by the ears and dunk it in a bowl of soapy water, all without us ever having to touch it. Thanks Horcik! You can see more of Horcik’s superb Elf-washing machine on Flickr – click the link above to take a look.

Rock Raiders

Lego Pneumatic Rock Excavator

Ah, Rock Raiders, one of LEGO’s thankfully short-lived late ’90s themes where they’d run out of ideas and decided to re-hash the ‘searching for magical crystals’ story just one last time. And the logo looked like a sexual diagram. We weren’t fans.

Anyhoo, we are fans of whatever this is. Suggested by a reader and built by previous bloggee Desert752Kirill it’s apparently a Heavy Rock Loader, and it looks like something from one of Thunderbirds weirder storylines.

Weighing 5KG and measuring almost a meter long, Desert’s creation is a goliath of the Technic world. It has gargantuan features to match too, with (by our count) twenty six pneumatic cylinders. These control everything from the boom elevation and extension, bucket tilt, the superstructure rotation, the four immense outriggers, and the adjustable-height suspension. The bucket also has a mechanical self-levelling function, and the model can operate with both normal and crab steering.

There’s lots more to see at Dessert’s Flickr photostream, the Eurobricks discussion forum, and of course, via the excellent video below. Click the links and be amazed…

Two Technic Tools

Lego Technic Pneumatics Snow Groomer

It’s a Technic double today, with two entries into the latest TC10 competition on Eurobricks. Both are pneumatically operated creations, as specified by the contest rules, and both show how brilliant LEGO’s little air cylinders can be.

First up (above) is this magnificent Technic snow groomer by Samuel Wharfe, with no less than six air-powered functions. The front blade raises, lowers, oscillates, and its edges can be adjusted to suit wider or narrower tracks, the rear blade can raise, lower and deploy smoothing rollers, and the whole vehicle can be raised above the snow via a pneumatic suspension system. There’s lots more to see at Eurobricks, and via Samuel’s Flickr photostream.

Today’s second pneumatic creation was suggested by a reader and comes from newcomer luukietechnic. Luukie’s heavy-lift telehandler, and it too features a wealth of functions. A Power Functions driven pneumatic pump provides air pressure for the boom elevation and self-levelling attachment, as well as a tilting cabin, whilst mechanics control the telehandler’s boom extension and four-wheel steering. You can see more of the build, including WIP photographs of the mechanics, at Eurobricks via the link above.
