Summer has come to an end and winter is just around the corner. Extreme heat and extreme cold temperatures outside have an effect on the way your elevator runs, so it is important to stay on top of maintenance to ensure your elevator runs smoothly with minimal error.
Seasonal Risks to Elevators
Winter preparation for elevators in cold temperatures is just as important for building owners as it is for the servicemen. As we enter the snowy months, make sure to keep an eye on door sills, as rock salt and ice coming off shoes can jam the sills and inhibit door operation.
When the heating system in the building is on during cold days, the shaft can act as a chimney and force warm air through the hoistway doors and up the shaft. The problem with hot air rising up the shaft is that it causes an increase in hoistway pressure and forces the hall doors to part a little bit, which could shut down the elevator. If you notice this problem, we can adjust door spring pressure to reduce this effect.
The machine room should be kept between 60 and 90 degrees Fahrenheit. Colder temperatures for hydraulic elevators can cause hydraulic oil viscosity changes and cause speed and leveling problems. If this is a concern, tank heaters are a good investment to minimize the effect of low oil temperatures. This problem will normally be seen in the morning after periods of low elevator use.
For traction elevators, cold weather can have an impact on the machine’s mechanical parts, including dry rails. The elevator may start to make a funny noise due to the lack of lubrication on the steel guide rails. When the weather gets colder, the lubricant dries out, causing friction between the moving elevator and the guide rails. Preventive maintenance and evaluation for adequate lubrication can help prevent this problem.
