The synchronization of handrail movement with step speed in an escalator is achieved through a mechanical drive system that directly links the handrails to the main drive system that powers the steps. This ensures that the handrails move at the same speed as the steps, providing passengers with a consistent and safe grip. The typical mechanism involves a chain or belt drive that connects the main escalator drive shaft to a series of pulleys or rollers that drive the handrails. The handrails are made of a flexible material, such as rubber or polyurethane, and are guided along a track that runs parallel to the steps. The drive system ensures that the handrails move smoothly and continuously along this track, matching the speed of the steps. The synchronization is achieved t....
