Xizi OTIS escalator parts chain 17 link escalator rotary chain

The escalator's slew chain is one of the main components used to drive the movement of the steps. It consists of a series of linked chains that run along guide rails at the bottom and top of the escalator.
The function of the slewing chain is to transmit power to the steps to make them move along the escalator track. It is usually made of high-strength metal materials to withstand the gravity and load of the escalator during operation. Slewing chains are precision designed and manufactured to ensure smooth operation and long-term durability.
