  1. Really, really beautifull !!! My compliments.
  2. Reasons for using rechargeable battery in the chassis had to do with the available space. Of course, the AAA-box can be used (which are used in the instructions). Reason for using the normal AA-box on top had to do with cost. It's not needed for counterwheight, a rechargeable bbox can be used there as well.
  3. [quote name='Kumbbl' timestamp='1450011846' post='2408130'] is it already listed in Rebrickable? i think not... Hmm, yes, manitou is red, but i would assume it would be easier to built in yellow and black (red --> yellow, white --> black)... well, yes, construction eqipment in yellow is somehow borring but if i assume right, then 1 42009 and 1 42030 would be a really good starting point for this outstanding MOC built in yellow - Juergen, what would you say? Top model, is now on my must build list [/quote] Yes, the combination of 42009 and 42030 gives you a very good start. You'll be able to compare parts lists soon, as this model has been submitted to Rebrickable.
  4. [quote name='Zblj' timestamp='1449958762' post='2407552'] That trully looks awesome! Did Blackbird help you with the half-transparent picture of motors and functions? [s]I think a video would do the model justice.[/s] [/quote] Yes, Blakbird made the transparent render. I can make instructions, but I cannot make renders like that

The chassis and the upperstructure are essentially 2 different models which can easily be separated and joined. Each has it's own PF receivers (or SBrick) and batterybox.[/background][/font][/color] [b] [/b] [b]Chassis[/b] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]Here's a list of all the functions:[/background][/font][/color][list] [*]* 4-wheel motorized drive (with 1 XL-motor) [*]* 4-wheel steering with return to centre [*]* 3 different steering modes: normal, crab and 4-wheel steering [*]* Outriggers can be extended and lowered [/list] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]The chassis contains a double switch to selects between "drive-mode" and "outrigger-mode". The double switch uses the new driving-rings to switch the functions of 2 motors. In driving mode the motors operate the driving of the model and the switch that selects the steering mode. There are 2 steering modes: normal steering, where only the front wheels turn. Second is 4-wheels steering, where the front and rear-axle turn in oppisite directions. And third is crab-steering, where the axles turn in the same direction. This makes it possible to make sideways-movements with the vehicle in small spaces. It's accomplished by using servo-motors for turning the axles. The front-servo always truns the direction in which you push the controll. The rear-servo is driven by a PF-switch, which in it's turn is moved by an M-motor (with clutch gear). This way, both axles are allways synchronized, you can even change steering mode while the axles are turned.[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]In outrigger-mode, the 2 motors can extend and lower the outriggers (as you'd expect). Unfortunately, the 4 mini-actuators used for lowering the outriggers are not strong enough to lift the enourmous weight of the model.[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]The side panels open up to reveal some of the motors (on the left side) and the batterybox and receivers (on the right side).[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]The batterybox can easily be removed to change batteries.[/background][/font][/color] [b] [/b] [b]Upperstructure[/b] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]The upperstructure has 4 motorized functions:[/background][/font][/color][list] [*]* Rotation of the complete upperstructure (with 1 L-motor) [*]* Raising the Boom (with 2 Linear actuators and 1 L-motor) [*]* Extending the boom with 3 sections (with 1 L-motor) [*]* Changing the angle of the attachment [/list] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]One of the challenges of this model was making the attachment / hook up and down. The drivetrain for this function had to extend together with the extending arm. In the real machines this is done by neatly folding the hydrolics-hoses. In my moc, it's done by using the red sliding 8-tooth gears introduced in the 42009 Mobile Crane Mk II. The red gears slide along 32L axles togehter with the section of the boom they're attached to. This way, the drivwetrain can be extended to more than twice it's length.[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]Extending the boom is the weakest function of the model. Even when using rollers, there's a lot of friction when the 2 inner sections of the boom are sliding out of the base-section, each with it's own rate. It will not be able to lift a lot of weight.[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]Rotating the entire upperstructure is done with 1 L-motor. The new big turntable from the 42043-set was used and reinforced with 4 support wheels / rollers to ensure smooth 360+ rotation. [/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]Since there are no wires running from the chassis to the upperstructure, the rotation is endless.[/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)][size=3]Again the batterybox can easily be removed to change batteries.[/size][/background][/font][/color] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]For cosmetic details, the cabin features an opening door, liftable lever (for better access to the chair) and detailed control panel.[/background][/font][/color] [b] [/b] [b]Remote controll[/b] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]The model can be controlled either with (4) power functions receivers and customized PF-joystick-controllers or with (2) SBricks. The building-instructions show the version with PF-components. But the PF-receivers can easily be replaces with SBricks, 1 SBrick in the Chassis and 1 in the upperstructions. This is my prefferred means of controll, as the ASBrick-system allows scontroll over the speed of the individual motors.[/background][/font][/color] [b] [/b] [url="http://www.jurgenstechniccorner.com/index.php/building-instructions/92-telehandler-building-instructions"][b]Building intructions[/b][/url] [color=#233943][font=Arial, 'Arial Unicode MS', Helvetica, sans-serif][background=rgba(255, 255, 255, 0.6)]Complete building instructions for this model are available [url="http://www.jurgenstechniccorner.com/index.php/building-instructions/92-telehandler-building-instructions"]here[/url].
