[MOC] CAT D7R LGP Bulldozer (with PF)

[Dennis Bosman]

This is not one of my most recent builds but I never published a video of it. Now I took some more indoor shots as well.

I started to build this dozer back in 2006 to be laden onto a Renault Magnum. First the model was driven by a RC unit, from set 8366. It ran OK but I didn't like the receiver and it took to much space in the model. Later I made my own control unit but that one was wired to make it possible to get the dozer blade operated by pneumatics. Later I decided to build in some PF stuff. My mate Barman helped me out with designing a compressor which is combined with the switch. I needed two of those and they just fit in the frame. I built in some PF receivers and gave the 9V RC motors another position in the frame. They're now put vertically. The looks are still the same as I was satisfied with it's appearance.

I remember this model from when you first published it! I am curious as to how you constructed the pnuematics system considering those cylinders have only one input.

This is how they're put in the frame:

The switches are operated by a lever which is connected to the compressor motor.

Love this. I'm a earthmoving contractor by trade and we have a D7H here, these kind of builds i admire greatly. Excellent job and detail.

Beautiful! Thanks for showing us the photo of the underside, too. I'd love to see more, especially to see how you crammed studless PF and semi-studless RC motors (with their strange shape and dimensions) into a studded vehicle.
