Cat’s Claw

Lego CAT 434E Remote Control Backhoe

Digging cats. It normally means they’re doing something horrible in your garden. Not today though, because this CAT 434E backhoe is something rather wonderful.

Built by Zbiczasty of Brickshelf it’s near a perfect functioning replica of Caterpillar’s real 4×4 backhoe, complete with no less than fourteen working functions.

The all-wheel-drive is remotely controlled, including remotely operable pneumatic differential locks, pendular front suspension, and three steering modes (front, all, and crab), exactly as per LEGO’s own brilliant 42054 Claas Xerion 5000 tractor set.

Of course there’s a working front loader – also powered by remotely controlled pneumatics – with both bucket and boom movement, and a fiendishly complicated pneumatic backhoe with five different movements from elevation to slewing.

Finally there are pneumatic stabiliser legs mounted at the rear and a suite of LED lights. It’s a remarkable machine and one of the most realistically engineered Lego creations that we’ve ever come across.

There’s a whole lot more to see of Zbiczasty’s Caterpillar 434E backhoe at the Brickshelf gallery via the link above, but the only way to really appreciate how well this model works is to watch it in action – check out the video below to see just how good it is.
