These days, everyone is researching ways to reduce their elevator maintenance costs and all sorts of building managers will explain that elevator repairs can be very costly, particularly when overtime service is required. The purpose of this information is to show you quick and easy things to look for when confronted with an elevator shutdown to lessen downtime and costly repairs. Most elevator shutdowns are door related. For self-evident reasons, the elevator was created to not run using the doors open. The doors must be closed completely and locked prior to the elevator will move to another floor. If the doors do not lock, the elevator will not run. Some door related problems may be the following:
Elevator continues to open and close the doors but will not leave the ground to reply to a call.
Elevator will not close doors whatsoever.
Elevator begins to close door but won't close completely.
Elevator doors appear to be closed but the elevator won't move.
Using some basic observations skills, many of these problems could be remedied without the tariff of calling your elevator company. Some safe and simple solutions for these troubles are given below.
Look for trash or debris at the end from the door in the door sill. The doorway sill guides the bottom of the doorway to maintain it from being pushed into the elevator shaft. Guides fit in the groove within the sill. The clearance in these grooves is nominal also it takes hardly any to jam the door so that it won't close properly. I have found from pocket change, bottle caps, paper, as well as very small screws wedged in sill. If the elevator doors do not close completely the elevator won't run.
Check the door reopening device. All elevators have devices that detect if the object is incorporated in the door to keep the doorway from closing on a passenger. A few of these are mechanical, some are electronic with infrared beams, and some have a mixture of both. The mechanical door detectors can get stuck within the retracted position causing the elevator to believe that somebody or something like that is obstructing the door. The infrared detector lenses can get dirty not allowing the receiving unit to see the infrared beam. Make sure the detector lenses are neat and free from dirt. Both of these will cause the doors not to close or sound an alarm and close in a reduced speed, with respect to the code restrictions in your town.
Check for stuck push buttons. Many times the elevator doors are not the problem at all. If your push button about the car or in the hall is stuck, the elevator will stay on that floor using the doors open. For instance, if the door open button is stuck, the elevator will hold the doors open. If the 2nd floor button is stuck, the elevator will go towards the 2nd floor and remain there using the door open. Often it is possible to get the button unstuck by simply pushing it several times. This is only a temporary fix. If the occurs, the button usually needs replacing and a technician should be called.
Most of the situations in the above list are billable calls not covered in elevator maintenance contract. Performing these simple things will help building managers reduce billable repairs, in addition to, elevator down-time. Remember to never make an effort to gain access to the top the elevator or open the elevator doors manually. This requires training. Elevators are electrical and mechanical devices. Great care should be taken when dealing with such devices.
