A lot of maintenance employees believe that small machine trains can be precision aligned more quickly and easily than larger machine trains. This is not always the case!  Smaller machine trains are usually less rigid. This can cause the alignment to shift as the anchor bolts are tightened.  Almost all small machine trains have some form of soft foot condition that must be corrected because the machine bases are often not flat or of inferior construction. Additionally, thermal growth can have a large impact on smaller machine trains as well.

Don’t be fooled by the size of the equipment you must precision align. It is critical to understand how the size, design, operation, and other factors affect the equipment you must align.
