Why Elevators Require Maintenance During the Winter?

Winter preparation is extremely importantfor elevators, and this is something most of us don’t know. As we enter thecold months, make sure your elevator is working perfectly fine. Keep an eye onthe elevator door sills, as ice and rock salt coming off your shoes can inhibitthe door operation and jam the sills. When the heating system of your home ison during winter days, the shaft may act as a chimney and pull warm air throughthe hoist way and up the shaft. The main issue with warm air rising up theelevator shaft is that it increases the hoist way pressure and forces the doorsof elevators to part a bit, which can shut down the elevator.

Similarly, for traction elevators, winterseason can have an impact on the mechanical parts of the machine, including dryrails. Also, when the weather gets colder, the elevator may begin to make anoise due to lack of lubricant on the guide rails. Evaluation for adequatelubrication and preventive maintenance can help avoid this problem

There is several elevator equipment thatyou need to prepare for the cold season. Otherwise you may get caught off-guardand have to shut down the elevator, while it undergoes repair. Also, it will bemore convenient and affordable for you to fix a problem before it gets out ofcontrol. Here’s a list of things you should look into while considering winterelevator maintenance and how they can guard your facility:

  • ConsistentTemperatures

Generally, the temperature inside anelevator and elevator shaft should be the same as everywhere else in thebuilding. So when there’s a drastic difference in the temperature inside theelevator and the temperature outside the elevator, condensation can build up. Ifthis newly-formed moisture makes its way into the electrical components of theelevator, it can cause component failure and equipment shutdown.

  • Slip andFall Prevention

Make sure that the entryway to theelevator is safe on each floor. Passengers expect to walk out of the elevatorsafely, so don’t have puddles forming in the building. This is much morehazardous during the winter season as people drag in ice and snow from theirshoes and while they wait for the elevator to arrive, the snow melts and formsa 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.

  • Lubrication

Dry air in winter can interfere with thefunction and efficiency of elevators. So you have to make sure that all railsare lubricated adequately to prevent friction between the rails and the lift asit moves up and down. Also, keep the hydraulic at an ideal temperature, whichis between 85 to 95 degrees Fahrenheit.

  • ClimateControls

If you do not have a climate controlledelevator car, then park it at climate controlled floors when not in use. Thereare devices you can easily install that will automatically take the elevatorcar to the desired floor when the elevator is not being used. Moreover, for thebuildings that are located in cold areas, the machine rooms of elevators shouldbe equipped with extra layers of insulation, especially for the hoist way andtank. Make sure to check that the insulation is adequate and intact.

  • EmergencyBattery

Itis important to check the battery backup system of elevators regularly inwinter. In case there is a power outage during a snowstorm, you should be surethat your elevators will function seamlessly. So the batteries should be fullycharged at all times in order to avoid service disruption.
