The invention provides an auxiliary brake of a passenger conveyor. The auxiliary brake can operate even if abnormity of the passenger conveyor except for breakage of a driving chain is detected. The auxiliary brake (50) of the passenger conveyor is provided with a rod (51) which is arranged opposite to a ratchet wheel (23) and is configured to move between a first position engaged with the ratchet wheel (23) and a second position separated from the ratchet wheel (23), and the ratchet wheel (23) rotates integrally with step chain wheels (16a, 16b) by utilizing driving force transmitted by a driving chain (18); a first solenoid (61) that displaces the lever (51) from the second position to the first position when energized; and a second solenoid (62) that displaces the lever (51) from the first position to the second position when energized.
本发明提供一种乘客输送机的辅助制动器,其即使在检测到驱动链条断裂以外的乘客输送机异常的情况下也能够进行动作。乘客输送机的辅助制动器(50)具备:杆(51),其与棘轮(23)对置配置,并构成为在与棘轮(23)啮合的第1位置和离开棘轮(23)的第2位置之间移位,棘轮(23)利用经由驱动链条(18)传递的驱动力而与梯级链轮(16a、16b)一体地旋转;第1螺线管(61),其在通电时使杆(51)从第2位置向第1位置移位;以及第2螺线管(62),其在通电时使杆(51)从第1位置向第2位置移位。
