Not a particularly catchy title, but accurate, as this ace mining truck is indeed constructed only from the parts found within the LEGO Technic 42114 Volvo Hauler set.

Redeploying 42114’s ‘Powered-Up’ motors and Control+ bluetooth control, builder Eric Trax has built an excellent companion for the enormous LEGO Technic 42100 Liebherr R 9800 set, with remote control drive, steering, and tipping bucket, plus – ingenuously – a three-speed automatic gearbox.

Whilst the scale is much smaller than that of the donor vehicle – as evidenced by the ‘steps’ leading up the front which give a clue to how massive this would be in real life – Eric’s creation still requires a hefty 1,700 pieces (around 80% of 42114), and can tip an impressive 2kgs of load.

A complete gallery of images, including a few of the truck alongside the official Liebherr R 9800 excavator set, can be found on Flickr by clicking here, where you can also find a link to building instructions should you wish to turn your own 42114 Volvo Hauler set into this mining truck yourself.

Cleverly, Eric’s 42114 B-Model uses the same Control+ profile as the donor set, so if you do make the switch you can drive it straight away using your familiar Volvo controls. Take a look via the video below to see Eric’s alternative in action!
