Big Technic Mobile Crane
Very very big Technic mobile crane that is strong enough due to my recent purchase of a modern (for me) 8880 Supercar, whose rigid axle connectors, black friction pins and many many beams made this possible...
About this creation


Have you seen those pictures of the modified 8 wheeled 855 crane in 80s Technic instruction books ? Ever wondered how big such a thing made using 8860 wheels would be ?
Oh well, I'm going to tell you anyway...



This beast used A LOT of pieces and weighs approx. 27,000 tonnes (slight exaggeration).
It has six wheel steering, with geometry that enables it to turn in little more than it's own length. This is controllable from the cab or a 'hand of god' wheel on the back.
It's got a flat 6 engine driven by the third (unsteered) axle, four folding, extending stabiliser arms linked to a single control. These can be deployed from the cab or another 'hand of god' wheel on the back. The other wheel on the back turns the crane arm.



Inside the crane cab, the levers are there to look pretty ... the hook is lowered and the boom lifted and extended by controls wheels behind the cab.



The boom has three pieces (so many beams...) with an extra section to 'bolt on' to the end, carried on the crane's chassis.



Here we go, I'll start to set it up on the kitchen table .... err ... when it's extended it's going to hit the ceiling !



Try again on the floor. If I spent time renovating the kitchen I wouldn't have time to make stuff like this ... Anyway I like blue and green...



Not the most detailed interior ever ...



With the boom fully extended ...



And the extra length added making a four piece lifting arm ...



Hopefully this illustrates how I've constructed the base of the crane arm. It's rigid enough to whack people over the head with (not that I'd try...) this is necessary otherwise it simply would not work under it's own weight, let alone any load..



And this is how big it is ... nearly six feet at full stretch.

WOW! This is the king of the big rigs! Love the look of the cabin. The functionality is very good - the twin steering is a nice feature. It's so well-built and the colour is perfect. There weren't enough blue technic kits were there? This is the industrial version of 8880!

Well Done. Did it once with the Yellow Crane , added 2 axles and an extra boom , but this looks much stronger... Harry
