I am from elevator manufacturing company in Saudi Arabia. I have been installing more than 1000 units elevator in Saudi. This is the first time I face this problem. 3 out of 4 elevators in one building were damaged the same way; where VVVF inverter, braking resistor and braking unit were damaged. All four elevators have been using since one year, recently the first unit was damaged 3 months ago, after one month the 2nd unit was damaged, then two weeks later the 3rd unit was damaged too. I have no idea why it happened in one building and so frequent. Why not other buildings in other location of Saudi Arabia. Please help me.
