This is a Casagrande C400XP2 hydraulic crawler, a machine built to, um… hydraulically crawl. OK, full disclosure, we don’t really know what it’s for, but it looks the business.

Powered by nine motors, this remarkable Technic replica of the C400XP2 comes from Aleh, and features subtractor tracked drive, a rotating superstructure, a multi-stage winch and boom, and a motorised 6-cylinder engine.

Even cleverer, all nine motors (even those driving the tracks) are fitted within the rotating superstructure, and with internal renders and building instructions available you can find out how it’s done.

There’s much more to see at Aleh’s Bricksafe folder and via the Eurobricks forum, and you can hydraulically crawl you way there via the links above.
