With this program I have attempted to replicate some of the guide rail and bracket spacing seismic zone requirements found in Part XXIV of the A17.1-1996 code. ( Section 8.4 in the 2000 edition ) This calculation is for a counterweight rail system. Keep in mind that I have tried to interpret the code as accurately as possible. If you have any suggestions as to how I might improve this program please let me know.
This calculation is for a hydraulic elevator car guide rail system.

Do you need to know the minimum rated load or the maximum platform area? Well...just plug in the area or the platform dimensions and you can calculate the minimum rated load. And of course...metrics are welcomed!
If you know the rated load and need to find the area and the dimensions of the platform use the second part of the program.
