I have finally found the time to finish this MOC of a Morooka tracked dumper.
It is loosely based on the Morooka MST 2200VD.
The model is controlled using an S-brick and powered by the regular lego technic power functions battery box.
Each track is driven by an PF L motor with a 1:1 ratio, giving the model plenty of speed and enough torque to drive over obstacles etc.
Dumping is also motorized using a PF L motor driving a linear actuator.
The battery box is hidden under the openable hood, and can be easily accessed and removed (although a lot easier if the dumpbed is up :))
Other functions include an openable door and a lock for the gate on the dumpbed, that opens if you dump.
I tried to make a video but you guys will have to wait a bit longer because my baby is making a lot of noise in the background so I have to make a new one sometime when he is asleep :)
Edit: made a new video - the period in the beginning when nothing happens is when the buwizz in the tractor fails to connect
