What is a typical hourly wage, and what kind/how much training is required? Is there a special certificate that you have to get, sort of like a driver's or pilot's license? Does it vary much depending on what type of crane (track crane vs. tower crane)?
In Sydney Australia a tower crane operator makes a little over $2000 a week after tax on average. Pay is about $40 to $50ph, alot of allowances + penalty rates. Expect to work big hours for the money though. To become an operator go to your local union office, they might point you in the right direction for your region.
Before you can operate a crane, you have to possess a trade certificate from a licensed agency. And before you got one, you have to undergo training and it depends on the extensiveness of the program of a licensed agency. the trade certificate is like a license, it has range of machines which you can operate with once license. Salary differs and it is based on hazards of work. A typical example is the crane operator in construction of Burj Tower. Being on the top of the building is not an easy job so the operator will likely receive salary more than a crane operator who is working in a typical high rise building.
