Q: How do they erect HUGE cranes without a crane?
They use Hydraulics. I don't know if you have any understanding of Fluid power but a hydraulics system can lift up to 400% of its weight multiplyed by its density. There are other factors to consider such as cylinder size, flow, and pressure but these are usualy constants. For example: If the hydraulic fluid used weighs 5 lbs. per gallon and its density is .9 gram per cubic centimeter then 1 gallon of this fluid could lift 53.1441 lbs. A jack system is hydraulic

Q: is was about making this game where this guy knows crane style
Like Sensei Scandal wrote, crane style is very rooted. No flips or crazy jumps so it is not acrobatic in that respect. Posture and balance is extremely important to the power generating methods crane style utilizes. The clips Scandal provided are very good and do demonstrate the posture well. If you look closely you can see quite a bit of modern karate in them.
Q: how do you win at the crane game?
im the master of the crane game. You gotta scope out the animal first! If it looks heavy then dont even bother. Whenever you grab hold of something its gonna pull it up and shake when it hits the top right? Thats why you go for something close to the hole it drops in. They have one where I work so I lock the wheels, grab the animal and pull the whole machine forward so that it just falls in the hole lol.
