Only one model today :D For a long time I wanted to build a classic agricultural trailer. It was supposed to be a standard double axle version. However, when I built the New Holland and Fendt tractors, I changed my mind and decided to build a tandem trailer. I made such a decision for a simple reason. The only output that can be controlled in tractors is the PTO shaft. This version of the trailer does not have to have a pneumatic system or engine to raise the kiper. In addition, the model had to be in a popular color because I wanted to create an instruction for it. The choice fell on Krampe Big Body 550. Trailer frame The frame is a fairly simple liftarm structure. The first version had a pendular suspension, but I had to remove it because the loaded trailer was unstable. Thanks to this, I could additionally strengthen the frame and move the cylinder towards the hitch in order to increase the load capacity. At the moment, it is about 1 kilogram Tipper I wanted to build a realistic model. Because of that I had to give up technic panels. If I used them, the tipper would weigh 1/3 of its current weight. Bricks are heavy, so the payload has dropped. The model looks very good like model–team one. I am glad that I managed to reproduce the curvature of the sides. The tailgate lifts automatically when the tipper is lifting. The trailer has a system of pull rods that lift it up. If the tractor has a pneumatic system, it can be replace by lego pnaumatic cylinders as a separate function Thanks for reading!

motomatt posted a topic in LEGO Scale ModelingYAPT (Yet Another Peterbilt Truck :) After recently catching the AFOL bug I found myself spending alot of time admiring Bricksonwheels' creations and Sariel's road train. Then after building one of Ingmar's trucks, I felt compelled to build my own. So here it is. Since I already build a lowboy trailer very similar to Ingmar's detachable gooseneck design in yellow and black, I went with a yellow and black color scheme for the truck. The truck has 5 PF motors. 2 XL motors for drive. Servo for gear rack steering. M-motor attached to a PF switch allowing remote control on/off of all the lights. This design is very similiar to the one found in Madoca's wing-body truck. The truck has head lights, tail lights, roof lights, as well as a PF connector in the back allowing the trailer's lights to use the same remotely controlled switch. An M-motor is used to lift and lower the third axle. Originally I made the truck with a two speed gearbox very similar to the one Madoca used in his SUV Mk II. Since the gearing allowed the truck to be rather fast and zippy in the faster of the two gears I decided to use dual XL motors for the drive. But after finding a few too many false neutrals with the torque of dual XL motors, I've since removed the gearbox. Now it seems that two drive motors are a bit overkill unless you're pulling a heavy trailer uphill. To make it a bit unique I set out to give it a third axle which can be remotely lifted and lowered. All wheels utilize technic shock absorbers. The cabin can fit a full size battery or the smaller rechargable one. From the top, it's 59 studs long. The two PF connector's just ahead of the fifth wheel are or for continuous power to the trailer and remotely controlled trailer lights. Here it is pulling a heavy 42030 Volvo wheel loader. Yellow overload. So originally I had no plans to make instructions, but once I started playing around with LDraw and Bricksmith, I just couldn't stop :-) The full instructions are available on rebrickable http://rebrickable.c...ellow-and-black The truck is up on MOCpages http://www.mocpages.com/moc.php/411142 More pics are available on bricksafe http://bricksafe.com...o Peterbilt 379 Many thanks to Aurimax https://www.bricklin...e.asp?p=Aurimax for the Chrome pieces.
