Dynamic speed tests are performed on the Step and Handrail simultaneously. This guages the relationship of speed transients between the step and the handrail. Measurements are made to a resolution of 0.1ft/min, at a rate of 30 per second. The data is used to generate detailed speed profile graphs.

This test provides an accurate indication of the following:

Stretched / worn chains
Worn sprockets
Step drive problems
Handrail drive problems
Compliance with Local / National codes and OEM spec’s

Safety is enhanced by:

Reducing the potential for falls resulting from the unnecessary activation of the broken / slack step chain device, broken drive chain device, or the handrail speed monitoring device.
