Escalator Investigations

The experts at Robson Forensic are regularly retained to investigate construction, maintenance, and injury claims related to escalators. Discussing these investigations with our clients, regardless of their nature, is often met with the same common hurdle – industry terminology. Few people outside of the industry are familiar with the anatomy of an escalator; for that reason we have provided the diagram below. We hope that this diagram will be a helpful tool for discussing the technical aspects of your case.

  • Comb Impact Device - Safety switch used to shut down the escalator when something becomes entrapped between the steps and the comb plate
