Abstract
A passenger conveyor system is provided with a driving unit disposed at an upper horizontal portion of the system and a linear motor disposed at a midway portion of the system for driving the passenger conveyor, thereby not requiring the provision of expensive linear motors over a full rise of the system, and adding a linear motor to only a portion of the conventional system, while the comfort of the passengers is considerably improved.
