hahaha....if the AE's report is correct, then it is a mechanical problem...the E-stop will not hold/stop the lift car in a stationary position...
something is missing here....they have done the rectification which means that they should have found the exact cause...jammed mechanical parts of the brakes, oily brake drum and worn-off brake liners??
but nothing in the statement confirming the actual cause???
Mechanical wear and tear is normal through time.
But there are several safety devices to prevent accident in case of mechanical breakdown.
Problem is, not all of them are aware of how to properly maintained the safety devices.
Most, I would say, would know how to replace the mechanical parts, but not on the electrical part.
And safety mechanical adjustment must be quite fine and accurate, in order to achieve best performance.
If not, the elevator will always shows breakdown every other week.
