Q

How do we Locate the car?

A

A. Floor indicator on Lobby control panel

B. Use intercom or telephone system of the stuck car…passengers may be able to give aprox. location

C. open hoistway door at FIRST FLOOR with elevator key and look up shaft..key devices are usually required at the lower levels and may be present at all levels….
-if hoist door has glass pane, check shaft BEFORE opening door, using flash light, look for the GOVERNOR ROPES and the COUNTERWEIGHT..movement of either one of these will indicate car is in MOTION, do not OPEN HOISTWAY DOOR…governor rope located on either side near one of the far corners of the shaft

D. location of COUNTERWEIGHT can be used to approximate the position of the car…Example: 6 story building where the elevator serves the basement, if the counterweight is on the 1st floor, the stalled car would be at the 5th…located this counterweight, by viewing through glass or opening hoistway door.

E. Enter car in same bank and open top hatch if no damage will be done to the elevator car

F. use the FLOOR SELECTOR in the MACHINERY ROOM, it indicates the EXACT location of elevator car

Q

Primary Removal Procedures are simple approaches, WITHOUT turning off the elevator power..there are 2 types, the order is not important…try all if necessary, they are?

A
  1. Checking electrical contacts (if passengers activated EMERGENCY STOP BUTTON, this will not work…have them DEACTIVATE)
    A. have passengers press Door Open BUTTON…if car is level with landing, this may work
    B. PRESS LOBBY CALL BUTTON
    C. instruct passengers to insure car door is FULLY CLOSED..have person push door towards closed position
    D. have members physically close ALL HOISTWAY doors in shaft…this will prevent air movement in the shaft
  2. FIREMAN SERVICE —this will OVERRIDE EMERGENCY STOP BUTTON
    A. activate fireman service- PHASE 1- stuck elevator may return to the main lobby or sky lobby and open its doors
    B. Fireman service should be deactivated when the car responds by returning to the lobby or if it’s clear that the car isn’t responding
