For Curved stairlifts Flow II and Curved Inclined Platform Lifts Supra it is very important to measure the staircase accurately so that the rail bending is done as per the staircase profile.

A photographic measurement System of Thyssen Krupp Access ezee Photo Survey is used to measure and recreate the staircase as built drawing. This drawing is generated on Autocad after taking photographs of the staircase with special markers(signalised points ) placed on the staircase depicting the dimensional parameters of the stairs. This drawing then forms the basis for the manufactuing of the rail .
