Sanjurk- being an engineer assuming you are referring to some kind of background in electronics is not sufficient to begin to work on an elevator. While it may be useful, you have to also have a very good set of mechanical skills and an overall knowledge of how elevators work which we learn over a period of years. This is a specialized trade and most of us here are members of the IUEC and have been doing this for years. These things can be extremely dangerous an accidents happen to even experienced mechanics that become careless.
