Winter preparation is extremely important for elevators, and this is something most of us don’t know. As we enter the cold months, make sure your elevator is working perfectly fine. Keep an eye on the elevator door sills, as ice and rock salt coming off your shoes can inhibit the door operation and jam the sills. When the heating system of your home is on during winter days, the shaft may act as a chimney and pull warm air through the hoist way and up the shaft. The main issue with warm air rising up the elevator shaft is that it increases the hoist way pressure and forces the doors of elevators to part a bit, which can shut down the elevator.
Similarly, for traction elevators, winter season can have an impact on the mechanical parts of the machine, including dry rails. Also, when the weather gets colder, the elevator may begin to make a noise due to lack of lubricant on the guide rails. Evaluation for adequate lubrication and preventive maintenance can help avoid this problem
There is several elevator equipment that you need to prepare for the cold season. Otherwise you may get caught off-guard and have to shut down the elevator, while it undergoes repair. Also, it will be more convenient and affordable for you to fix a problem before it gets out of control. Here’s a list of things you should look into while considering winter elevator maintenance and how they can guard your facility:
- Consistent Temperatures
Generally, the temperature inside an elevator and elevator shaft should be the same as everywhere else in the building. So when there’s a drastic difference in the temperature inside the elevator and the temperature outside the elevator, condensation can build up. If this newly-formed moisture makes its way into the electrical components of the elevator, it can cause component failure and equipment shutdown.
- Slip and Fall Prevention
Make sure that the entryway to the elevator is safe on each floor. Passengers expect to walk out of the elevator safely, so don’t have puddles forming in the building. This is much more hazardous during the winter season as people drag in ice and snow from their shoes and while they wait for the elevator to arrive, the snow melts and forms a puddle. This melted snow tends to accumulate in the elevator’s door sills, which can cause door equipment failure if the doors don’t fully open or close.
Dry air in winter can interfere with the function and efficiency of elevators. So you have to make sure that all rails are lubricated adequately to prevent friction between the rails and the lift as it moves up and down. Also, keep the hydraulic at an ideal temperature, which is between 85 to 95 degrees Fahrenheit.
- Climate Controls
If you do not have a climate controlled elevator car, then park it at climate controlled floors when not in use. There are devices you can easily install that will automatically take the elevator car to the desired floor when the elevator is not being used. Moreover, for the buildings that are located in cold areas, the machine rooms of elevators should be equipped with extra layers of insulation, especially for the hoist way and tank. Make sure to check that the insulation is adequate and intact.
- Emergency Battery
It is important to check the battery backup system of elevators regularly in winter. In case there is a power outage during a snowstorm, you should be sure that your elevators will function seamlessly. So the batteries should be fully charged at all times in order to avoid service disruption.
