Question: 1 / 475

What maximum speed is normally attained with modern oil type hydraulic elevators?

100 fpm

150 fpm

200 fpm

Modern oil type hydraulic elevators typically attain a maximum speed of around 200 feet per minute (fpm). This speed is suitable for many typical applications where hydraulic elevators are used, such as in low-rise buildings. The design and mechanics of hydraulic systems allow for smooth and efficient operation, which is essential for passenger comfort and safety.

In contrast, speeds below this range, such as 100 fpm or 150 fpm, may limit the elevator's efficiency in servicing buildings with moderate traffic. Speeds over 200 fpm, like 250 fpm, generally exceed the typical operational capacity for oil type hydraulic elevators and are more characteristic of traction elevators, which use a different lifting mechanism that allows for higher speeds and greater distances. Thus, the selection of 200 fpm reflects the standard capabilities of hydraulic elevators in common usage.
