I'm pretty sure that company left out a lot of detail of what happens early in 
the process.  They are probably freeze-drying the bodies for a long time to 
eliminate the liquid in the body.  Then I suppose the bodies might be fragile 
enough to fall apart easily when shaken.
 

In any case, this is not a problem for cryonics patients.  A large fraction of 
the water in the body is replaced with various chemicals; but the mass and 
structure are preserved.  While a rose or a banana frozen to LN2 temperature can
shatter easily, a preserved human or animal body at that temperature is very 
hard to break.  Animal bodies are reinforced with bone and fiber and are much 
more solid.
 

Alcor's patients have been exposed to an earthquake in Southern California, 
transportation by truck to Arizona, and the daily vibrations of vehicles being 
driven past the building.  In the situations where we have had cause to examine 
patients (transfers to new containers, for instance) or the more frequent times 
when we have examined preserved animals for various tests, we have never seen 
any evidence that they are vulnerable to being shaken into dust.
 

Finally, someone else pointed out to me that the "Mythbusters" television 
program actually tested a pig frozen in liquid nitrogen and were unable to 
damage it much more than chipping off a few exterior pieces.  November 4, 2009, 
Episode146   They were reproducing a scene from a "Jason" movie.

How vulnerable are preserved patients to vibration?
 
Obviously,  liquid nitrogen can make certain things very brittle.  I'm sure
you've seen the videos of a rose being flash frozen and shattered with a
hammer, or a similar one with a balloon.  Well, I read that there is a
Swedish firm called promessa that destroys bodies this way, by dropping them
in liquid nitrogen and subjecting them to "light vibration".
 
How vulnerable are patients in a cryonics storage vault to this?  Will the
hum of nearby machinery or a small earthquake cause the patients to turn
into a pile of shattered pieces?
 
Here's the website where they show the process
