Mini Minecraft

Lego Mining Excavator

Lego mining excavators usually appear here in huge fully remote controlled form. Not so today, as Michael A’s mining excavator is – being mini-figure scale – rather smaller. Surprisingly though, Michael’s build still features a fully functional arm and bucket, thanks to the inclusion of several mini linear actuators from the Technic range that can be hand-cranked via the wheels hidden throughout the build. It’s a neat trick and one we’d like to see more of in Town scale creations. There’s more to see of Michael’s working Town-scale mining excavator at his photostream – click here to take a look!

Smooth Moves

Lego Caterpillar Excavator

Smooth cats are usually properly weird. Not so this one, which comes from previous bloggee Sheo and is – as you can see here – exceptionally smooth. It’s a Caterpillar 320 hydraulic excavator and there’s more of it to see on Flickr. Smooth things over by clicking here.

Mini-Figure Mini-Digger

Lego Hitachi ZX75US-5B Excavator

Founded over a century ago, Hitachi – perhaps most well known for televisions and hi-fis – make pretty much everything. Consumer electronics, ATMs, power stations, computer servers, trains, elevators, air-conditioners, tanks, construction equipment and much more besides. It’s one of the latter we have today, built by Y Akimeshi of Flickr in Hitachi’s signature orange. It’s a ZX75US-5B 7-ton excavator in mini-figure scale, complete with tracks, a rotating superstructure and a very neat brick-built arm. There’s more to see at Akimeshi’s photostream – click the link above if you dig it.

Volvos in Space

Lego Technic Volvo ConceptYou wait all day for an autonomous Volvo concept loader, and then two come along at once. Or so the saying goes. Following the 42081 Volvo Concept set, LEGO and Volvo have teamed up to run a competition to design the Volvo construction vehicle of the future.

Here are two entries, each packed with Power Functions motors and remote control functionality, and each looking quietly terrifying to boot.

First up (above) is R. Skittle‘s ‘Volvo Proteus’, a fully autonomous self-loading hauler. Many many motors power the loader’s drive, all-wheel-steering, the huge swivelling bucket arm, and the sliding and tipping bucket, and there’s much more to see at Skittle’s photostream. Click the link above to view the full gallery of this superbly engineered creation.

Today’s second concept (below) sends Volvo into space, with this enormous ‘Mars Mission’ loader/dozer/tunneller/excavator, all the things required for some Mars-based construction. Built by Desert Eagle (aka Desert752) of Eurobricks this metre-long monster is powered by sixteen motors, with all-track drive, crab steering, a self-levelling superstructure via linear actuators, 360 degree excavator boom rotation with elevation, extension and a synchronised counterweight, 360 degree tunneller boom rotation and elevation, and a drill head that looks like something from your Mom’s Ann Summers chest.

There’s a whole lot more to see of both of today’s Volvo concepts via the links above, and you can enter the competition yourself via LEGO Ideas by clicking here.

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.

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.

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.

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.

Size Isn’t Everything

Lego Micro-scale Vehicles

At least, that’s what your Mom told this TLCB writer. It’s a philosophy adopted by Flickr’s LEGO 7 too, who has constructed this charming micro-scale scene in which none of the vehicles are more than two studs in width. They’re all instantly identifiable though, with a taxi, police car, excavator, cement truck, ambulance, semi truck, coupe and bus all recreated brilliantly in miniature and placed within a clever modular roadway. There’s lots more to see of all the vehicles plus the neatly designed base at LEGO 7’s photostream – click the link above to check it out.

Lego Technic Volvo EC950EL Excavator Remote Control

This TLCB writer was peacefully working today when one of the more unusual sounds to penetrate the office came floating through the door. A cascading metallic rush followed by screaming, it sounded like a tin of thumbtacks being emptied over a TLCB Elf. Sigh. Still, no Elf is strong enough to upend a full tin of thumbtacks over one of its colleagues, so it couldn’t be that.

Oh yes it could. Thanks to previous bloggee ShineYu‘s remarkable fully remote controlled Volvo EC950EL excavator, a multitude of thumbtacks had indeed rained down on one of our Elves.

Lego Technic Volvo EC950EL Excavator RC

Much too slow to run down any of its colleagues, the Elf at the controls of ShineYu’s Volvo had deployed some trickery to allow it to cause maximum carnage. This involved loading a tin of thumbtacks into the excavator’s bucket, using the four Power Functions L motors that control the arm to raise it high above the floor, and then lying in wait for a curious Elf to walk underneath it.

Carnage achieved it then ran off cackling delightedly, leaving us to pick up tacks, and to pull a few out of a very sorry looking Elf. Whilst we do that you can check out more of ShineYu’s huge Volvo EC950EL at the Eurobricks discussion forum, where you can also watch a video of the four excavator arm motors in action, as well as the two XL motors that power the tracks and a third that rotates the superstructure.

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.

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.

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.

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.
