liftarm or linear actuator? They're probably just trying something new. If they didn't, we'd all complain that the only new angled panels introduced in 2015 were scarce because they existed for one year only. I believe your statement about getting rid of liftarms is wide of the mark anyway - panels tend to fill in gaps that would probably have otherwise been left open. Even in really great MOCs, you never saw huge walls of liftarms (possibly lucio switch excluded) so unless the design philosophy changes, there's not much effect on the result except for look. I've not seen panels used as structural elements yet either in the sense that you can't build orthogonal structure or gear trains around and through them like you can with liftarms. tldr: probably the same kind of angst that was seen when technic bricks were replaced with liftarms. It was not much more than a change in direction.

wow - very impressive steering mode change. Well done! I look forward to seeing the rest of it come together and I hope you will finish it even if you can't make the competition deadline.

this quote may be of interest http://www.eurobricks.com/forum/index.php?showtopic=99748&st=550#entry2363641 A cross type outrigger set may well negate the design rules that force certain configurations with stabilisers running across the frame.

'tis indeed enough to make a grown pirate drool Thanks Ole

Have fun - there's a thread in here somewhere in the last couple of pages from the top that should quite a few examples of it. Mine has a crane on it, but you could probably find someone who's put the 8043 on it ;) I think it's a great build and the automated gooseneck detachment is a work of art. Ahh, here it is http://www.eurobricks.com/forum/index.php?showtopic=102992&hl=

Do you want a trailer or semi trailer? If a semi, an appripriate fit would be Ingmar's yellow lowloader. He has instructions for fitting it to the 8258 and it is characteristic of something that would be used to carry a large excavator. http://rebrickable.com/mocs/2legoornot2lego/trailer-tr4-mkii-8258-with-instructions If a trailer, i'd build M-Longers or pat-ards 4axle bogie jobs.

Wow - full points for teamwork commitment!

1974 often posts pics of 'strange' things

Hi GT Thankyou very much for the description and explanations. I appreciate your effort. Whilst I can see why gerger was keen on an all wheel drive carrier, it's not done that way on the real one. The fixed differential I haven't seen before and as you say, significantly increases the centre clearance of the vehicle which would help greatly on dirt paths with raised hump in the middle.

The pressurised valves working, so in the machine. i kind of have an idea about all sorts of hissing noises, but it might be the steam fanatic in me . But that's a great demonstration of the setup, thanks.

Wow - that's amazing. More than watching it work i'd love to hear it :)

raise the floor a foot, put a structural glass walkway over it and live on your collection.

Wow - looks quite different in yellow. A striped bumble bee :)

sounds imaginary! I build only for fun, and part of my fun doesn't involve being first to publish a video of a build, so I can take my time :)

They were good open ended models with flexibility to rebuild by imagination and most of them had great swooshability. You basically built your own story with them, which is missing from the starwars franchise. Yes - bring back the old stuff.

Looks very interesting. It will be exciting for you to see if the real thing meets your expectations.

Hi Saber not a brochure so much as blurb from the company making the hydraulics for it http://www.linde-hyd...40-002b03edd46c mostly talks about use in turbines being height/capacity limited at 3MW units, although any crane can be used for a much larger array of tasks. It appears as though this is still a prototype even two years after that was published and nothing more is said on the manufacturers site other than a recent test http://en.zoomlion.c...elease_text.htm Part of where I was going with the axle loading was not related to road use, but part of the ''all terrain" title. Some parts of the world have great sealed roads (my place is not one of them) that can support 150psi tyres. The softer unsealed ground that these cranes are asked to work on can't support anything like that and if you need to build a road for it (and you may need lots and lots and lots of mats to do it) then the crawler again wins on footprint. Don't forget as well that a 2000t class crawler wouldn't be needed for the equivalent job. You'd get away with a much smaller unit since the lattice boom cranes have much better lift height and load-moment performance than the mobiles. The crawler would be 2000t at possibly 110m+ boom height, but the mobile would be stuck at close to zero boom extension, as shown in that press release link photo. (compare to a Manitowoc 31000 for example https://www.manitowo...e-boom-crawlers). That QAY2000 is doing 750t at 10 metre radius -> something a smaller crawler would laugh at. An added performance benchmark for that kind of load moment performance is that lampson used to advertise their weights as lift and carry, meaning you could use a quite small crawler compared to a mobile since the mobile would need a much bigger load moment capability as you can't re-position mid-lift. I was just googling around that QAY2000 description when I found their time comparison. I'm a little enthusiastic with the crawler assembly, but it's not crazy when you think of moving on a wind farm site where there may only be 200-2000m between successive lifts. no doubt it's an impressive bit of kit - i just don't see a market outside china, which means all the (practically zero) published info so far is chest beating "look at me" stuff rather than a design intended to be sold in western markets. I did see a significant South African company influence in one link though, so it's possible. Something else - searching for models of it came up with this: http://forum.dhsdiec...=posts&t=134161 It's hard to tell from your pics, but I don't think it's a 12axle crane as much as a 9 axle carrier with rigid link attached 3 axle trailer for carrying the boom. Is that how you'd view it? the Leibherr LTM11200 also has an operating weight of 108t (12t/axle) and it's 'only' 1200t class. I think the real weight is much higher as you've noted and the 96t is only the carrier weight, not that of the carrier plus boom. This thing would have to transport boom separate as well, which requires additional heavy lift gear just like a crawler. http://www.liebherr..../measure-metric In the end, it's all a bit moot with the nil data available for it and the fact that most turbines are installed at heights over 130m, requiring boom extensions for both types.

that chinese 12 axle unit is interesting, but I doubt it would be street legal in many parts of the world. Too long, too high, too much boom overhang. The most conservative estimate of axle loading at 8 tonnes (assuming the 96000KG stamp on the door is the gross weight) is pushing a lot of limits as well. Their brochure touts it as a fast turnaround alternative to crawlers due to quick rigging and setup time, but given permits for moving, limited speed (probably no more than 50km/h if that), daylight hours only and the size of the support crew required just for the ballast, I wonder whether the day or so setup time for a crawler would disappear in the travel time for this AT unit, where the crawler went by 'normal' trucks. They must have done the numbers and believe they can sell enough, but I wonder if they're expected to be domestic sales only given it seems to be specifically aimed at wind turbine installations. Be an interesting thing to model but as krisandkris12 says, handling it would be ridiculous. Not just as a play thing, but trying to build it! I envy LiftingBricks as much for his techniques as well as his designs. Still, if you want to take it on, more power to you and good luck

Thanks for the update. I bought the instructions and full parts for both the trailer and the mercedes, but the parts will take a while to get here. Would you suggest I wait for the new truck instructions? Sounds like a big change - was you reason to change to visual style or make it stronger?

That'll be exciting. From your website it looks like you're upgrading the Actros as well. I'm still getting the parts together for both of these - have you changed much on both?

Well, it depends on what you're building Saber A monster truck or telehandler would happily take equal angles. Same with any rigid chassis capable of crab steering. A sportscar on the other hand would have quite different values. For the trailer, you have to think about the point about which the whole thing rotates, then the steering angles are made to keep the wheel rotating around that point. For trailers it gets tricky and they're pretty much always a stopgap value because even if the prime mover holds a constant steering angle, the turning radius of the whole assembly will keep getting smaller. ie, they generate spirals, not circles for fixed steering input. aminnich aminnich - see if you can find youtube examples of a four wheel steer car (like honda prelude for example) and compare that to a telehandler and a 3 axle bus. I've seen some vids where they do a full steering lock to lock motion so you can see what happens. The prelude also had two modes I think. A high speed one where both axles turned in the same direction and a low speed (or parking) where they turn opposite.

it's a slipery slope as a collector when you widen scope. I speak from experience :D Having said that, both the 8855 and 8854 are great examples and with the exception of the half and half 855 stands out as the only red crane in the whole lineup of technic cranes. It's also fun to play with and a fabulous example of a truck crane rather than the more usual all terrain units with custom carriers.

not quite what I was expecting. It's not support for lego, it's using lego to support electronics breadboarding. Still, an interesting use of it.

"you raise me uuuppppp......" Great looking machine

i've always been ambivalent about this sentiment. To bring stuff back is great for those who don't have one, or never saw the original, but it devalues the rarity of the original.
