String Theory

Leave a reply

Unifying quantum mechanics and general relativity, String Theory proposes that the universe is composed of vibrating one-dimensional strings instead of points, incorporating all particles and forces into a single framework. Alternatively it’s adding some string to a LEGO set to make a new one. We’re doing the latter today…

This is paave’s Technic mobile crane, and it’s built only from the parts of the 42175 LEGO Technic Volvo FMX Truck & EC230 Electric Excavator set. Plus a piece of string.

Featuring working steering, outriggers, boom elevation and extension, superstructure rotation, and an inline-6 engine, paave’s alternate is an excellent reconstitution of the 42175 donor, and one you can build for yourself as instructions are available. As long as you have some string. Find a link to them and further build details on Eurobricks via the link above.

Tow Plow

Summer is waining here in the northern hemisphere, which means for many readers, and perhaps TLCB Team, we’re on the path to winter snow. Fortunately previous bloggee M_longer is ready, having converted his LEGO Technic 42175 Volvo FMX Truck & EC230 Electric Excavator set into this spectacular Volvo VHD snow plow, complete with a gritter and secondary plow trailer in tow. A ‘tow plow’ if you will.

Utilising around 2,100 pieces from the 42175 set’s 2,274, M_longer’s alternate features working steering, a piston engine under the opening bonnet, a disengageable salt spreader / gritter, a pneumatically elevating front blade and – very cleverly – a pneumatically elevating trailer blade too, driven by the truck’s pneumatics.

Building instructions are available and you can find a link to them, full build details, and a reference image of the real ‘tow plow’ truck that inspired this build at the Eurobricks discussion forum, there are over forty high resolution images at M_longer’s ‘Tow-Plow’ Bricksafe gallery, plus you can check out this fantastic alternate in action via the video below.

Half-a-B

What’s half a B? A D? Whatever it is, that’s what we have here today, in the shape of the excellent Technic bulldozer by Flickr’s Dyens Creations, who has constructed it only from the parts found within LEGO Technic 42175 Volvo FMX Truck & EC230 Electric Excavator set, specifically the pieces used to build the EC230 excavator.

An array of working functions feature, and the bulldozer can still fit onto the Volvo FMX’s trailer, for which the pieces – and those of the truck pulling it – remain unused. There’s lots more of Dyen’s half-a-B-Model to see at his ‘LEGO 42175 – Heavy Duty Excavator’ album, and you can swap your digging for dozing via the link in the text above.

LEGO Technic 42175 Volvo FMX Truck & EC230 Electric Excavator | Set Preview

Following our preview earlier this month of the brand new H2 2024 LEGO Technic sets you may have been wondering where the promised fourth real-world vehicle was. Well today can we reveal all, starting – as the more eagle-eyed reader will have spotted – with the new 42175 Volvo FMX Truck & EC230 Electric Excavator not being one real-world vehicle at all, but two.

Following a long tradition of truck-with-trailer-and-vehicular-load Technic sets, 42175 ushers Volvo’s off-road FMX truck and electric EC230 tracked excavator into the Technic line-up, bringing pneumatics back in the process.

Aimed at ages 10+ and constructed from 2,274 pieces, 42175 features working steering, a tilting cab, and a six-cylinder engine on the truck, fold-down ramps on the trailer, and a 360° slewing superstructure and a two-stage pneumatically-operated bucket arm on the excavator.

There’s also a ‘charging station’ that can be lifted off the trailer by the excavator for when it needs some more electricity, which we can only assume in real-life would be a giant battery or – more ironically – a diesel generator. Either way it looks a bit pointless within the set, doing precisely nothing whatsoever.

The three other components (truck, trailer, excavator) look sufficiently playable however, if a little under-endowed aesthetically for the £170 / $200 asking price. This is particularly true for the excavator’s bucket arm, which uses two small buckets to create one of the correct size. If this approach isn’t to support a B-Model, it’s a bit of a corner cut.

Still, 42175 could be a worthwhile addition to the 2024 Technic line up, and you’ll be able to get your hands on it when it reaches stores in August of this year.
