[MOC] R/C Backhoe

[timslegos]

Hello,

I finally present to the forum my first all studless build, my remote control backhoe!

This project has definitly been the largest so far. the remote functions include:

drive

steering

loader arm up/down

loader bucket tilt

rear boom up/down

dipper in/out

bucket tilt

boom swing

the manual functions include:

3x pf lights

outriggers

extending dipper

The front loader arm is controlled by 2 large actuators and 2 mini actuators for the bucket.

The cabin is where the lights and the outriggers are controlled via the pf switches. This is also my first attempt at a comfortable chair .

The pf receivers are hidden inside the steps into the cab.

When getting prepared for digging, the outriggers and front bucket are extended, lifting the whole machine off the ground.

Even without the dipper extended, the arm has quite the reach.

This is what the dipper looks like extended.

The rear arm is very compactly built, and i was very inspired by Jurgmeister's backhoe on brickshelf.

What it looks like from behind.

Overall, i am very satisfied with this model. Since it was my first all studless build it was quite a challenge. Unfortunately i couldn't afford to make a brickshelf order so not all the parts are the color i wanted them to be, which is why i had to put the huge battery box inside the cab instead of the smaller AAA battery box. i got a little distracted towards the end by my next project...a snowgroomer with a twist .

More/larger photos can be found on my Brickshelf page: Brickshelf

Finally the video:

Comments and critique welcome!

Your Lego Technic R/C Backhoe is excellent! It's got a nice mix of "studded" and "studless" construction. Great MOC!

I am really excited by the snowgroomer. i am building it so it will actually be able to go in real snow!
