Hi all,

I would like to present you my latest MOC. It is a wheeled excavator based on the Liebherr 900C. The goal was to made it remote controlled by using the SBrick and with manual pneumatics system.

I started with a blueprint of the Liebherr 900C and made a rough model in the LDCad. The final model is in scale of approximately 1:16.7. The wheeled undercarriage is 33 studs long and 19 studs wide.

There are 4 remote controlled functions. These are using 4 motors - 3 L motors and 1 M motor.

L motor - rear wheel drive, front wheel steering, air pump

M motor - platform rotation

All motors are in the rotated platform. The drive and steering goes through the turntable by using the clutch gear for two coaxial functions. Thus the platform can be rotated in 360 degrees without limitations. (The only downside is that during rotation of the platform it is slowly moving and steering.)

The boom has three manual functions and it is composed form two parts plus bucket. There are two large pneumatic cylinders, one long cylinder and one small. All pneumatics are controlled by switches behind the cabin.

The last manual function is extension of rear outriggers. It is done by a small knob in the rear part. Outriggers are extended by small linear actuators.

I will also try to make my first video :-)

Thank you. The tubing still can be improved. I was limited by hoses I have from my only pneumatic set - the 42043. And of course I didn't want to cut some of them. So inside it is pretty stuffed. Also I had to use one gray hose for one of the large cylinders, which is not perfect.

Agree that the Volvo tubing can be much better, but otherwise it will be good source of pneumatic for MOCs.
