CAT330D-L full hydraulic

[Erik79]

Hi guys,

Forgotten to answer to Azonic; the hydraulic motor setup like you see in video has a wheel torque of about 24-25 Kgcm at 25 BAR and can hold, without be backdriven at all, a torque of about 22 Kgcm.
But in this version the displacement is 15 cubic centimeters (for a wheel turn), so around twice the one of the first prototype.
Not a huge value, but is already proportional to the scaled torque of the real machine: the Cat 330D has a thrust equal to its weight, 30 Tons, and the model has a thrust of about 12 Kg like its final weight.

See you....
