Skid Marks

Lego Technic RC Skid Steer Loader BuWizz

Sometimes you don’t need a million-horsepower hypercar as inspiration for a brilliant Technic build. This is a humble skid-steer compact tracked loader, and it is one of the most fun-looking Technic models TLCB Elves have discovered in ages.

Built by Nico71 of Brickshelf this tiny Technic toy is packed with working remote control functions, which – thanks to a third-party BuWizz bluetooth battery/controller – are super-powered too.

Two Medium Motors power the tracks, providing both drive and skid-steering, whilst a further pair of motors linked to linear actuators operate the bucket arm and tilt-mechanism.

Thanks to its small size and the extra power from the BuWizz battery Nico’s loader is a riot to chase Elves down the corridor with, er… we mean rigorously test, so whilst we do that you can see more by clicking the link above, and you can read our review of the BuWizz bluetooth battery that powers it by clicking here.

D11T Dozer

Lego RC Caterpillar D11T Bulldozer

Caterpillar’s D11T bulldozer has appeared here in Lego form numerous times over the years (you can use the search bar at the foot of each page to look up past D11Ts, or anything else that takes your fancy!), and this may well be the best incarnation of the enormous earthmover yet.

Built by previous bloggee Sheo, this 1:24 scale behemoth is a marvel of Lego engineering. Underneath the incredibly realistic exterior is a fully remote controlled drivetrain and blade/ripper, whilst pendular suspension allows the model to drive smoothly over bumps and a cunning planetary subcontractor design enables realistic skid steering. There’s also a motorised access ladder, LED lights and an automatic track tensioning system too.

There’s more to see of Sheo’s incredible Caterpillar D11T at his Flickr photostream, where you can also find a link to watch a video of the model in action. Click the link above to make the jump and take a look.

Elven Eviction

Lego Caterpillar D11T Bulldozer RC

All was quite in The Lego Car Blog Towers this morning. The Elves were asleep in their cage room and we were quietly watching the Monaco Grand Prix qualifying, er… we mean working studiously in the office.

And then came the sound of several soft thuds, kind of like a series of bean-bags falling off a table, followed by great Elven rage. Sigh.

A wander down to the cage room revealed the cause, where an enterprising Elf had returned early in the morning whilst its colleagues were still asleep, and promptly driven a remote control bulldozer through the Elves’ cages – much to its own amusement – pushing them out and onto the floor below. Cue the Elven rage.

Unable to escape by riding atop the ‘dozer due to its limited speed, the unhappily awoken Elves had caught their attacker and were trying to feed him into the VHS machine. Mr. Airhorn was deployed to restore calm (which definitely awoke any Elves fortunate enough to avoid the original incident) and we’ve now taken control of the offending vehicle.

Lego Caterpillar D11T Bulldozer RC

And what a vehicle! Based on the Caterpillar D11t bulldozer, Piotr K‘s creation is a superb example of how to utilise both Power Functions and pneumatics.

Two Power Functions L Motors drive the tracks, which are suspended by a pendular equaliser bar, whilst three M Motors power the pneumatic systems, with one driving an on-board compressor (with an auto shut-off) and the other two activating the pneumatic valves. This gives Piotr’s model a continual supply of compressed air to power the huge front blade and the rear-mounted ripper which can be operated remotely via LEGO’s IR system.

It’s very neatly engineered set-up and one that works – as the Elves found out – really effectively. You can see more images and read about the build on MOCpages via the link above, plus you watch the model in action via the YouTube video below.

The Other Challenger

Lego Challenger MT-865 Tractor

The Dodge Challenger has appeared here numerous times over the years. This isn’t that Challenger. Nope, this one is made by Caterpillar, and it comes from a series of tractors that were the first to be specifically designed to run on tracks.

This brilliant Model Team recreation of the latest Challenger MT865C comes from the appropriately-named Eric Trax, who has done a simply astonishing job replicating the Caterpillar in Lego form. And Eric’s creation is far from a static model…

Lego Challenger MT-865 Tractor

Inside the beautifully constructed exterior are a wealth of electronic and pneumatic components, allowing Eric’s Challenger to drive, skid-steer, and power both an on-board compressor and power-take-off.

Hooked up to the back of the MT865 is a Kinze 1050 grain trailer, complete with its own Medium motor and pneumatics to control the unloading auger.

Lego Challenger MT-865 RC

All of these functions can be controlled remotely via bluetooth, thanks to the third-party SBrick concealed within the build. This enables the models to be controlled by a phone or, as Eric has done, by a Playstation 4 controller!

There’s much more to see of this amazing Caterpillar Challenger MT865C tractor and Kinze 1050 grain trailer at both Brickshelf and the Eurobricks forum – click the link to see all of the images and to read complete build details.

Diggin’ Double

Lego Technic Remote Control Excavator

LEGO’s excellent Power Functions components have brought a new ease to motorising Technic models. Small, simple to install and reasonably powerful, the wide range of motors, infrared receivers and battery boxes have found their way into countless Lego creations featured here over the years.

It didn’t take long however, for the clever boffins in the Lego Community to think ‘Great… but what if Power Functions was really powerful?…’

The result is the BuWizz brick, an integrated rechargeable battery and bluetooth receiver that delivers up to eight times the power of LEGO’s own Power Functions system. To which Anto of Eurobricks thought ‘Great… but what if I had two…’

This is the fruit of Anto’s endeavour; a neat if unspectacular looking Technic excavator, with two BuWizz third-party bricks. The first controls the independently driven tracks (each powered by a Medium motor), the front-mounted blade (also powered a Medium motor) and the arm-mounted LEDs.

The second BuWizz device controls the superstructure rotation (via a Large motor), the two-stage arm (via an XL motor and Large motor respectively), and finally the bucket (powered by a Medium motor).

That’s a lot of motors and, thanks to those two BuWizz bricks, a lot of power too. So much so that Anto’s Technic excavator really can, well… excavate. Full details can be found at the Eurobricks discussion forum, and you watch Anto’s excavator in action via the video below.

Dumped!

Lego Bucyrus RH400 Mining Shovel

It’s Valentines Day here at The Lego Car Blog, and what better way to celebrate it than with a post about an epic dumping! This TLCB writer is totally fine about it though, and he’s not even thinking about you Laura.

Anyway, this is a Bucyrus RH400 mining shovel, one of the largest mining excavators in the world, and it’s capable of dumping 45m³ of rock, up to 75 tons, in a single bucket.

Built by previous bloggee Sheo this 1:48 Model Team recreation of the Bucyrus RH400 is an near perfect miniaturisation of the 900 ton excavator, right down to the way it operates.

LEGO’s Power Functions motors drive everything including the two-stage boom and tipping bucket, the tracked propulsion, superstructure rotation, folding service ladder, rotating cooling fans, and a gearbox to switch between these remotely operated functions.

There’s a whole lot more to see of Sheo’s Bucyrus excavator at Eurobricks and Flickr – click the links and join this writer in completely forgetting about Laura.

Febrovery Silliness

Lego Febrovery Squirrel NUTS

The annual sci-fi bandwagon that is Febrovery is upon us! Our Elves have found two Febrovery entries to share today, the first of which appears to be staffed by highly intelligent squirrels.

Flickr’s Miro Dudas explains that the Neptunian Utility Transport Services (N.U.T.S.) have got themselves a new crawler to support their appetite for oversized acorns (which grow upon and must be harvested from the Neptunian moon of Triton). A team of four hardworking Squirelites named Sandy, Andy, Mandy and Randy operate the crawler and the supporting harvesting machinery collecting the acorns which are blown far and wide due to the strong Neptunian winds. A risky business, the team of four Squirelites were apparently last seen a year ago… Right, stop that! It’s silly. Now let’s see something decent, and military. 

Andreas Lenander‘s classic space rover may not be military exactly, but it does make fantastic use of LEGO’s otherwise pointless X-Pod piece, and there are no squirrels to be seen anywhere. Unless they’re in that box. A fearless classic spacewomen is ready to load the cargo into the back of the rover which is sure to make it home thanks to those nifty brick-built tracks. See more of the X-Rover and a box that may or may not be filled with four long-dead squirrels at Andreas’ photostream via the link above.

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.

Enormous Erection

Lego Technic Liebherr LR 11000 Remote Control

Even your Mom hasn’t seen one this big.

This is a Liebherr LR 11000 crane, and it’s seven and half meters tall in its full configuration (or 2.5 metres when indoors so it fits!). Built in 1:24 scale, this brick-built behemoth weighs 27kg, including 5kg of lead ballast. Other than that lead weight, some string, and a few 3D-printed pulleys, the entire model is completely constructed from standard LEGO pieces. Which makes it even more astonishing that this enormous replica works.

Lego Technic Liebherr LR 11000 Remote Control

Dawid Szmandra is the engineering genius behind the build, and yes this 27kg Lego creation really does work. With four Mindstorms EV3 processors, nine motors, seven light sensors and a touch sensor, this incredible creation can do everything that the real Liebherr LR 11000 can do. Only at one twenty-fourth the scale. Which is still massive.

Lego Technic Liebherr LR 11000 Remote Control

The drive to the tracks comes from two EV3 Medium Motors, whilst another can rotate the entire superstructure. Five Large Motors plus another Medium power the six separate winches, whilst the sensors can measure the load and winching distance.

The result is a crane, built entirely from little plastic bricks remember, that can lift a chair. There’s only one way fully appreciate what this incredible creation can do and that’s to view it in action. Join us watching in amazement via the video below, and you can see all the images of Dawid’s unbelievable model at his Flickr photostream and via the Eurobricks discussion forum.

Komatsu 3000

Lego Komatsu 3000

This big yellow box is a Komatsu 3000, which sounds like a robot from the Terminator movie franchise. It is in fact a 19ft wide, 1260bhp bucket excavator, with a top speed of 1.5mph. One point five! This fully remote controlled Lego version of the Komatsu 3000 is even slower, and thus can cause no carnage in the office today, much to the disappointment of the Elf that discovered it. It is still worth a look though, as it’s one of the most impressive RC creations we’ve seen in some time. Ayumi is the builder behind it and there’s more to see on Brickshelf here.

Belarusian Bout

Lego DT 75 Tractor

Iiiiin the red corner, weighing in at 12,676 pounds, the Belarusian bruiser…. the DT Seventy Fiiiiive! Aaaaand in the blue corner, also weighing in at 12,676 pounds, the Soviet smasher…. the DT Seventy Five Eeeeemmm!

We hope your internal monologue became suitably boxing announcerish as you read that. Anyhow, now that we’ve affected the voice inside your own head, you can see more of these beautifully built town-scale DT 75 and DT 75M tractors at Jakeof_’s photostream. Click the link to go ringside.

Minecraft

Lego Technic Mining Excavator

It’s been a summery weekend here at TLCB, and this writer has been enjoying the great outdoors. Spare a thought then for those working far away from the sun, bringing us the materials out of the ground that we use in everyday life. However, one upside to such a job is that someone gets to drive machines like this one; the huge mining excavators.

This one isn’t huge at all though, having been thoroughly miniaturised by builder Krall, yet it’s still packed with Technic functionality. A rotating superstructure, rolling tracks, a two-stage motorised arm and a motorised bucket all feature, and there’s more to see of Krall’s creation at his Flickr photostream and at the Eurobricks discussion forum.

Big Yellow Beaver

Lego Komatsu

This Komatsu PC210LL-10 loves munching on wood.* With a 365 harvester head it can strip a tree of its branches in seconds, enabling the trunk to be neatly stacked on the back of a waiting truck. Flickr’s Mathijs Bongers is the builder and he’s replicated the tracked forest harvester brilliantly in mini-figure scale. See more on Flickr via the link.

*Just like your Mom.

Febr-over

Lego Febrovery Sci-Fi Rover

The annual bandwagon that is Febrovery is over for another year, with rovers of all shapes and sizes being submitted by the online community. We’re ending our coverage of this year’s event with two rovers from the very opposite end of the roving spectrum.

First above (above), and suggested to us by a reader, is this neat tracked satellite dish transporting rover, resplendent in a Classic Space livery and with a beautiful classic space monorail pictured behind it. There’s more to see at RVA LUG’s photostream by clicking here.

Today’s second Febrovery entry (below) comes from previous bloggee F@bz, and although it too is mini-figure scale, it’s an enormous machine. There’s some wonderfully inventive building in evidence too, and you can see more at F@bz’ photostream by clicking here.

Despite having zero sci-fi knowledge we’ve rather enjoyed this year’s Febrovery, so much so that we may get involved next year (although probably not in the way you’d expect!), so until then, happy roving, and we’ll return to vehicles of a more earthly nature.
