As the chilly season continues, you may be focused on making sure your building lobby stays warm and dry. But have you considered doing the same for your elevators’ engine room? In this article we share our best tips for making your elevators run smoothly and safely during a cold snap, winter storm, or flash flood.
Even early in the winter, before the worst of the cold sets in, there are several actions you can take to minimize any disruption to your elevator traffic.
Monitor the temperature
Your top priority should be to keep the engine room properly heated — minimally in the 50 to 70 degrees Fahrenheit range — and to eliminate any leakage into the space of outside cold air.
If your elevators run on a hydraulic system, it’s crucial to ensure that the temperature of the hydraulic oil does not drop to a point where it impacts system performance. In a worst-case scenario, cold temp
eratures can cause the hydraulic oil to congeal. This thick oil can trigger anything from erratic levelling of the elevator car to a complete system failure.
For peace of mind, some building managers choose to install a tank heater in the oil reservoir to maintain an oil temperature of 85-95 degrees, which is considered optimal for peak performance.
Another important checkpoint in cold conditions is to proactively ensure that the steel rails are properly lubricated. This will prevent any squeaky noises and possible disruption of operation if a problem develops during peak usage periods.
Clear the halls, floors, and doors
To avoid problems with elevator doors opening and closing, it’s important to maintain a regular regimen for keeping both the car- and hall-side door tracks clear of debris all year.
The winter season, however, calls for increased vigilance since tracks can quickly become clogged with packed snow, ice, salt, mud, and even pine needles from holiday trees. Over and above professional maintenance, you may want to consider doing your own intermediate touch-ups such as thoroughly vacuuming out the door tracks, and using paint brushes or a stiff nylon brush to help loosen and remove common track debris.
Stay safe during winter floods
In milder weather conditions, winter storms can bring severe flooding — which in turn can cause major issues for your elevator traffic. Here’s what to consider when expecting the worst.
Prior to an anticipated storm:
- Check the condition of the pits to make sure that sump pumps are not clogged and permitting ice and snow to accumulate. Further, it is vital to never operate the pumps in the presence of such buildup as this can cause freezing of the trolleys and substantial damage to the travelling cables.
- Check the function and charge of the battery backup to ensure the operation of emergency lowering during any storm-related electrical outages.
- Barricade the motor room to prevent, as completely as possible, entry by a substantial volume of water.
- Close the hoistway vents and openings to keep water out of the shaft.
During flood conditions:
- Move the cars to the top floors, shut down the system and power, and ascertain that there are no remaining building occupants who are dependent on the elevators to evacuate.
