  1. Hi guys, I'd like to present you my MOC of a Motorgrader, which is based on a CAT 120M2. I worked on this for about 6 months since I saw this video, hence the color scheme. The goal was to recreate as many functions of the real grader as possible, which I'd like to show in this little video. There are many pneumatic and manual functions. The grader also has has pendular suspension on front axle and twin pendular on the back wheels. Pneumatic: - Moving of front blade - Moving of rear ripper - Moving of middle blade with 3 cylinders (up/down/sideways) - Tilting of middle blade Manual: - Steering - Articulation of rear end steering for tighter turning circle or grab steer - Tilting of front wheels - Vertical turning of the blade - Shifting the blade to left/right side - Spring loaded, lockable center pin for left/right swing motion of the blade attachment mechanism One of the most challenging things has been to angle the blade for grading embankments. Therefor I needed this swing motion of the blade mechanism with the lockable center pin (notice the height difference of both pneumatic cylinders). The whole scale has been chosen according to the pneumatic cylinders (friggin expensive 1x11), where the new 68.7 tires fit perfectly in my opinion. As the cab is stuffed with pneumatic hoses, I have dropped the idea of implementing a seat and interieur. The scale fits nicely with the Arocs, which strangely is missing one pneumatic cylinder ...
  2. I present you my Moc of grader Number of parts: 1891 --> x1 XL for propulsion, x1 servomotor for steering and x1 IR receiver --> all functions are pneumatics -> x1 Lmotor to drive 2 compressor cylinders, x1 airtank, x1 automatic compressor shut-off valve, x4 control valves, x4 pneumatic cylinders. --> 42030 wheels --> 6cyl. in line fake engine The blade cylinders are independent, it allows to tilt the blade
  3. Hi Guy, i will show you my last Project. A Grader in Scale 1:12,5 and Style form Volvo G940C. I build this one this year for Bricking Bavaria 2016. The Grader have the most Functions then the real Model. One Function is missing. Here a list of the Functions: 1x L-Motor Autovalve for Lift Up/down the Front Blade 2x L-Motor Autovalve for Lift Up/down the Middle Blade 1x L-Motor Autovalve for Slide the Middle Blade Left/Right 1x M-Motor Autovalve for Lift Up/down the Rear Ripper 1x M-Motor for Compressor 1x Servo for Steering 1x M-Motor for Rotate the Middle Blade 1x M-Motor for Articulated steering 1x XL-Motor for Drive 1x M-Motor to change the Gears in the 2-Speed Gearbox The Decals are Printed on the Liftarms. Tires are not Lego. But in the Diameter have Lego no tires.

    Grader

    Hello all! I want to present my MOC - remote controlled (RC) Grader. Total construction time – about 4 months. Total length without rigs – about 80 cm. Weight – 5 kg. Total parts quantity – 5200. There are 12 independent RC functions: five mechanical: - All-Wheel Drive (3 x XL); - Two-stage steering (1 x L – forward wheels steering, 2 x M – articulated chassis); - Forward wheels tilt (1 x M); - Mouldboard rotation (1 x L); and seven pneumatic (5 x M – I used scheme with dependent and independent valves, as illustrated on picture below, so I exclude two additional motors): - Forward and rear PPTOs; - Mouldboard attack angle; - Horizontal mouldboard shift; - Diagonal mouldboard shift; - Left and right main mouldboard cylinders. The two-pump compressor is auxiliary function and it has independent RC too (1 x M). All of these functions are provided by 17 Power Function motors connected to seven IR Receivers and two AA-Battery Boxes (electric scheme of the model you can see on the picture below). Model composition: Total pneumatic hoses length – 14.8 m. Scheme of pneumatic connections: The model has opening doors with locking, realistic mirrors and lights, some versions of rigs – forward (additional blade with pneumatic control or additional weight for mouldboard pressure increasing) and rear (pneumatic controlled ripper). Opening bonnet makes possible a visual control of pneumatic valves working. Paralleling of the Power Function channels is realized by covering/uncovering some IR Receivers by using independent RC channel (mode switch). The mode switch consist of three M-motors, one of them is used for dependent pneumatic valves management. The model is very big, so I create special platform for its transportation. And a small video demonstration: Thank you for your attention!
