Lifting Equipments Inspection Agency

In India the State Factory inspector is the authority who gives competency certificate. Every state has its own factory inspector

Take a look at the web sits of some companies from those countries you list, they will most likely detail their certifiying authorites. In depends on what type of lifts you are doing. If you are heavy lifts try Mammoet, PSC Heavy Lift, Abnormal Load Engineering or ALE Lastra, if it is just cranes there are too many to list. Google is always a good start.
