How do I get areas with a certain elevation out of a raster file?

I have SRTMs for a country and I need to get a layer with the different altitudes that i can use later on for the weighted overaly:
Following are the classes:
0m-1100m
1100-1500m
1500-1800m
1800-2500m
2500-2800m
2800-3000m
3000-8000m
I tried reclassify, did not work. For visuals I can display the wished classes with the contour polygon, however, I cant really use it later with other polygons (when I want to intersect for the weighted overlay).

How can I calculate (i tried raster calculator but did not get anywhere) the needed elevation polygons? I have all extensions.

Thank you.
