New technology is frequently introduced, but safety regulations don’t always cover changes.
by Robert Kaspersma
New elevator designs are regularly introduced, yet safety regulations do not always cover them. This means it is important to have all the risks covered. New designs involve new maintenance and inspection methods. It is the manufacturer’s responsibility to ensure that, with development of new designs, proper inspection and maintenance can be performed. The starting point is a risk assessment, or failure mode and effects analysis. The results of this assessment or analysis are converted to procedures normally covered in product manuals. Therefore, it is essential these manuals are always present at the installation, even when the maintenance company changes. This brings up a new challenge: new designs need to be able to be maintained by other companies, to keep them conforming properly. Certification of these new designs by a Notified Body (NB) or Accredited Elevator/Escalator Certification Organization (AECO) should not only cover the original design, but also proper maintenance and inspection.
