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.
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.
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.
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.
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.
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.
