    So awesome!

    Welcome! Are you referring to a standard truck like this: or maybe a side loader truck: or something like this: I'm sure something like the first truck has been done, and I think somebody build a side loader sometime last year. The last truck is similar to the 8052 Container Truck that LEGO sold a couple years ago.

    Tim, that may work, but I think you will need plates all the way around. If you need wires going through the center, I'm not sure that is doable. Here are several more ideas: The one in the center is a bit more compact, and I think is more similar to what efferman used. The other two designs allow for an axle to pass through the center. The one on the left uses four 6L links with the ball pins, and the one on the right uses the 5L links with regular pins. I'm not sure the 5L links will work, and I don't have any of those links to test it. I'm wondering if there is sufficient clearance between the link and the teeth on the inside of the turntable. I think there will be, but I'm not sure.

    I wondered if that would work, although I wasn't sure if the half beams would be strong enough. It would be worth a try. Another option is to place the central axle next to the yellow beams, but that would make it one stud offset from center. Maybe there is a way to mount 4 half beams around an axle? I didn't realize anybody has used this method already. Nice to see that it works well! Back before LEGO used the Technic turntables, LEGO used to use a threaded axle with nuts that was run through the center of a 4x4 turntable. The threaded axles came in 10L and 4L lengths. Nuts were used at both ends, with a technic plate above and below the turntable. Several sets used this method, although the Power Crane is the only one I can remember off the top of my head. The parts are available on bricklink, although you will probably have to order from Europe. Instructions showing how the threaded axle was used on the Power Crane: http://www.peeron.com/scans/8854-1/13/ http://www.peeron.com/scans/8854-1/17/

    One of my local LEGO stores has the Service Truck and Crane in stock. No Exclusive Crawler yet. The local TRU also had the Service Truck.

    Tim, here is what I'm thinking: It's basically two turntables sandwiching the vehicle chassis (red beams). The yellow beams are what your superstructure would be attached to. Using this setup, there is no way your superstructure can separate from the chassis. I would suggest using some counterweight too though, otherwise the yellow beams could break from stress. The only downside to this is that there isn't really any room for a drive shaft going up through the center, unless you got all fancy with the design. There is room for wires though. The farther apart you place the turntables, the better it will be. It would also be better to have slew drive gears on both turntables. I haven't built a real version of it, but I'm planing to use this idea on several future builds.

    I may have a solution for you, but give me a coupe hours to post it. I like your project.

    -UCS Millennium Falcon. LEGO had it 50% off on their website, and I'm such an idiot for not buying a couple. They are worth some money now! -First couple of modular buildings. -The black and red Model Team semi tractor from years ago. I wish I had those wheels.

    That Terex is awesome! The AC700 has been on my list of things I want to build for several years. I'll probably never get around to building one. Saberwing, you should do a wip thread about the crane.
  10. dhc6twinotter
    I was under the impression that LEGO is going to sell the crane for $219.99 USD. At least that is what some of the links posted here in the past have stated. $239.99 sounds about right for TRU since they usually have a ~10% hike on their stuff in the U.S.

    I may be wrong, but I thought the outriggers and drop axle were controlled by a switch on the truck.
  12. dhc6twinotter
    Has anybody built a 100% remote control rotator tow truck?
  13. dhc6twinotter
    You have an amazing amount of functions packed in there! The method of uncovering/covering the IR receivers is both simple and genius. Nicely done.
  14. dhc6twinotter
    I think it will take several months, if not longer to sell out. I could be wrong, but I don't think there are even 1000 Technic nuts like us that are chomping at the bits to get this. My guess is that there are several hundred fans that read the various forums and know this set is coming. Otherwise, I think the rest of the 20,000 sets will sell from people browsing the LEGO stores or website. Maybe I'm totally underestimating the number of fans that read the forums, but I really don't think the set will sell out on the first day.....or week.....or month. I will be stopping by the store on the 4th for my set, if they are in stock by then.

    Yup, that is correct. The motor makes it harder for the differential to turn, so when you turn one wheel by hand, the other will turn in the opposite direction. When the motor turns the differential, both wheels will turn in the same direction. It sounds like you've built it correctly. Differentials are sooo cool!
  16. dhc6twinotter
    Does this happen when the motors are running, or just when you turn one wheel by hand?
  17. dhc6twinotter
    They are a neat piece of equipment and are fun to build as well. I started one about 1.5 years ago or so, but haven't worked on it for a very long time (I've been on the road for the past year and haven't built anything). I don't know that I'll ever finish it. This forwarder built by Jonas makes me want to begin work on mine again.
  18. dhc6twinotter
    I would love to see LEGO build a Forwarder. I think a remote control forwarder could totally be doable for LEGO. 6 functions would cover the basics, and a gearbox similar to 8043 could be used. It would have the same number of PF components as the excavator. 8 functions would be more realistic, but I'm not sure LEGO would go that far. Even if LEGO were to build a pneumatic version, it would be fantastic as well. If I were fortunate enough to ever work for LEGO, this would be one of my first suggestions, along with a motor grader.
  19. dhc6twinotter
    Sounds good!

    Very nice crane! I like all the CAD pictures you've created. They give a nice overview of how the various mechanisms work.

    Hey all, While browsing youtube, I ran across this fantastic Komatsu 840 Forwarder built by Jonas/JH-Create: Objectives Authentic proportions Mechanical crane (not pneumatic) 100 % remote controlled Joystick controlled Strong enough to actully load and carry small logs in the forest Video at the end of the post. Functionality Forward / reverse with 8WD Articulated steering Rotating hitch – Independent tractor and trailer Locking mechanism for rotating hitch Working bogie axes Boom Slew Boom up/down Jib up/down Grapple open/close Grapple rotate Fake 4 cylinder engine Datasheet Propulsion: 2x PF XL motor connected to a common drive train Steering: Frame steering by two small linear actuators powered by a PF M motor Hitch lock mechanism: Micro motor Boom Slew: Large turntable turned by PF M moto Up/down: LA powered by PF M moto Jib up/down: LA powered by PF M motor [*]Grapple Open/close: Wormgear driven by PF M motor Rotate: Micro motor More info on his blog: http://www.jh-create...-forwarder.html He has some other nice mocs on his blog as well, but I really liked the forwarder.

    That is awesome. Quite a lot of functions going on. I especially like the spring mechanism on the PF switches and the way you used all those CV joints to power the gun. Nicely done.
  23. dhc6twinotter
    My local LEGO store told me August 1st for the Service Truck, Crane, and the Exclusive Crawler.
  24. dhc6twinotter
    This is a really impressive moc! You have an amazing amount of functions on this, and I love the complexity of the head. It's great to get so much recognition from Ropa as well! What an honor. I do have one question: Is the rear steering controlled independently from the front steering?
  25. dhc6twinotter
    If it's a quality control issue, then I'm glad the motors aren't available yet. I'd be a bit upset if I bought 4 servo motors that I need only to find out they don't work properly. It's nice to see LEGO makes an effort to stand by the quality of their product and are not willing to sell junk.
