The program looks specifically at three key areas: Step Deflection; Dynamic Step & Handrail Speed; and Stop Performance. The graphical analysis resulting from these tests allow the identification of many problems associated with accidents. For example: Worn or damaged step rollers, axle rollers, bearings and bushing; worn drive chain and handrail drive problems; brake related problems.

All tests are non-destructive and do not require internal access to the machine. Typically the time required to perform these tests will be less than one hour on site, where as the time required to gather similar information with traditional techniques could exceed more than one day.

A cost comparison between this type of testing and a traditional equivalent shows that twice as many inspections can be performed for typically the same price.
