63-05: Vibrations of Cooling Tower Fans

The writing is confined to towers having fans, and is 
addressed to persons having some knowledge of towers. 
Underlying matters are Safety, and maintenance Economics. 
The immediate objective is to throw light on the vibration
 problem, caused by the presence of fans and running gear. The vibration problem is reviewed under the heading of balancing; Standards; Measuring; Monitoring; & Nature of
 Vibrations. The treatment is on the level of a simplified
 review and analysis that falls short of a specialist
 discussion in the realm of vibrations. Tentative standards
are offered and conclusions are given. The Velocity
 system is advocated for tower monitoring; although no 
firm recommendations are Given in any area. The writing 
disclaims any wishto influence policy, but does offer the 
sort of tactical knowledge upon which policy might be 
successfully built. There are about 28 total pages in 
the writing, or the equivalent of say 14,000 words.
