Again, if the lift is overloaded it still CAN slip through the brake (no matter how good it is), no amount of limit switches and overspeed devices (and if it does slip through the brake the govenor WONT activate because its not going fast enough and if the overspeed switch trips(NOT the mechanical govener)does trip wont stop the lift from sliding..obviously you dont know lifts and are looking for an excuse to blame the lift service contractor, if you are that worried employ a consultant (gee never though id say that) to survey the lift. We cant give an analysis as we DONT know the condition of the lift and DONT know the circumstances behind it.
