Crawler Loader

My favorite One Set MOC from bulldozer 8275 I created. Equiped with drive, tilted and lifted bucket, only with part of 8275. Including MLcad building instructions.

This is my first one set moc with 8275, I wanted to build a affordable moc with interesting and reliable functions for the AFOLs. I think I have succeed. 2 XL motor drive crawler with 8/24 reduction. Two M motor operate bucket movements. The technique I used is a simple worm gear with lever and connecting rod (in a parallelogram construction). The building instructions took  up many time, about 50hours, spite of I have built this moc in 10 hours. But the result is quite good : building instructions look professional.

    Well, I have to say that it was a pleasure and a nice challenge to build your Loader. Thank you very to give us the instructions. It is really appreciated!

    […] The drive is composed of 2 XL motors with 12/20 reduction. The XL are placed under the back and powered each track on the same axle. The trick I used is to placed the XL in face together and pass the power on the same axle. That is why I could put a pendular suspension on the front to be more realistic than my precedent loader.
