This is a Sandvik Toro 60, a sixty-ton 6×4 mining truck. Named after a bull (and the number sixty), the Toro 60 is unusual in that it doesn’t articulate like many mining trucks. This is so that it can withstand a higher payload, but of course with no central articulation there would be a loss of manoeuvrability, so the Toro 60 deploys a clever steering rear axle to ensure it can still turn around in less space than it takes your Mom.
This marvellous Technic recreation of the Sandvik comes from builder Thesuperkoala, who has replicated the Toro 60’s cunning steering thanks to a Power Funcions Servo motor that operates both the front and rear axles. The two rear axles are driven by a Large Motor and the huge tipping bucket can be raised by a large linear actuator, all of which are controlled by a third-party SBrick, allowing activation via bluetooth.
There’s lots more to see of Thesuperkoala’s fully remote controlled Technic Sandvik Toro 60 at his Flickr album, on Eurobricks, and via his own website, plus you watch the creation in action courtesy of the video below.
