Catenary Curve

An updated catenary curve for a turbine-generator giving the actual positions of the bearings as they currently exist shows the alignment health of the unit and how much the alignment deviates from design. The updated catenary curve can help identify marginal alignment issues and possible foundation changes. It can also be useful in long term alignment move planning.

Mechtell catenary curves show the complete alignment status of the machine because they provide both the horizontal as well as the vertical bearing positions.

Mechtell generates catenary curves by measuring the relative positions of the shaft centerlines near each bearing. We can generate the curves with the exhaust hoods and bearing covers on or off.

High definition industrial photogrammetry and/or laser trackers are used for these measurements.
