Jon googly eyes are needed here .LOL
The scrap yard where I used to do some work for has several of these beasts One they actually call "T REX" because it is so huge and can bite through just about anything. But as strong as those things appear believe it or not they can be broken a lot easier than one would think. once the cutting edges become dulled side biting it is called where only one side of the jaws are being used to tear and rip the movable jaw can be forced into the opposite side. the Hydraulics are so powerful and since the operator can only see the material being cut and in most cases not see the jaws the movable jaw can be broken completely off before the operator knows what is happening. Think of moving you own jaw from side to side then biting down real hard you will break your teeth.
