Definatly yes. As the ram has no movement anymore because it is blocked by the arms locked in to the Hardox, the third arm would be going nowhere.

@Alex: that would only work if the front of the robot you are trying to squeeze is square, on a recantgled shappe (wider than it is high) that would never work. Or with a high robot as an opponent you would lift your robot of the ground first, bfore the sideclaws come into action.

With Splinter we had 2 rams, 1 to close the claws, 1 to fire the axe, which we also used as grappling hook sometimes to drag an opponent into the pits.
