Article 10- Difference between Semi-Outdoor and Fully-Outdoor Escalators

Semi-outdoor escalator and fully-outdoor escalator differences

In this article, we intend to explain in detail the differences between semi-outdoor and fully-outdoor escalators.

The first deference is related to the installation environment. Semi-outdoor escalators and moving walks are installed outside the building while they have roofs above them to be protected against rain and snow. However, fully-outdoor escalators and moving walks are installed outside the building without any roof or other overhead covers. Obviously, since semi-outdoor escalators and moving walks are outside the building, they are not in a temperature-controlled environment. Therefore, in comparison to the indoor escalators, they have some additional extra options, depending on the geographic location of the installation environment. Examples of these extra options include a cooler, which cools down the device in high-temperature situations, or a heater, which heats the device in low-temperature conditions.

Fully-outdoor escalators and moving walks are also in exposure to some environmental elements, such as rain, snow, etc. These types of products have a large number of options, including lubrication-free rollers, water/oil drainers, etc. Even though this type of device is capable of operating in all weather conditions, standards recommend a roof over them for more safety. For example, in case the escalator or moving walk lacks a roof, passengers have to hold an umbrella above their heads in rainy or snowy conditions and this may cause danger of falling.
