The escalator pulley group is a system composed of multiple pulleys used to support and drive the operation of the escalator. The pulley group usually consists of a driving pulley and multiple guide pulleys. The driving pulley is usually driven by a motor or transmission, while the guide pulley is used to guide the escalator chain along the escalator track. The design and installation of the pulley group are crucial to the normal operation of the escalator. It can reduce friction and resistance and ensure the smooth operation of the escalator.
