In this video, The Elevator Consultants reviews a fully original 1990s Dover car top — untouched, unmodified, and still operating with all its original components. This includes a DMC controller, original slide guides, original hangers, and an HD85 Dover door operator design dating back to estimated 1985.
This walkthrough explains how these components function, which items are typically replaced during modernization, and why many of the original components remain viable decades later. It also highlights the door operator equipment, including the spirator, and explains how modernization affects door performance and reliability.

PROFESSIONAL INSIGHT:
Original Dover systems from the 1980s and 1990s remain some of the most durable components in the industry. When elevator consultants evaluate modernization needs, identifying which original parts are still functional and which need to be replaced is essential to maintaining safety and performance.
Door operators, slide guides, hangers, and tracks are often first to be modernized, but every system is unique, and sometimes equipment on the hoistway side is upgraded while other parts remain original. This video shows the type of component review done during TEC audits and modernization planning.
