Generally speaking it is almost always impossible to accurately decipher the meaning of the symbolism on any personal coat of arms. Many of the arms in use today, or on which today's coats of arms are based, were granted hundreds of years ago and if there was ever a specific meaning to the symbols, then this is probably lost in history. Even in situations where there are records of the granting of arms, rarely, if ever, is the symbolic significance recorded.
The specific meaning of each element of a coat of arms is subjective. Though the original armiger may have placed particular meaning on a charge, these meanings are not necessarily retained from generation to generation. Unless canting arms incorporate an obvious pun on the bearer's name, it may difficult to find meaning in them.
The one you linked to in your question has an obvious violation of the rules of heraldry by placing gold and silver together, so one might question it's validity, but this does sometimes historically occur. That rule is not to have metal touch metal, or tincture touch another tincture as this one has gold and silver touching.
English blazon: Paly (verticle) of six Gules (red) and Argent (silver) on a chief or (gold), a crowned eagle Sable (black).
A palett of six red and silver( six verticle lines of red and silver) on a chief or (a gold section at the top above all), a black crowned eagle (aquila is Latin for eagle).
For further research I would look into the meaning of the name and image name because they are reflected in the shield itself with a black eagle and crown.
