Abstract: A passenger conveyor including body frame is formed of a main frame including upper and lower horizontal sections and an inclined section therebetween, and upper and lower auxiliary frames mounted on the upper and lower horizontal sections of the main frame, respectively. A front side of the upper auxiliary frame and the upper horizontal section forms a recessed portion, and a driving device for driving handrail is provided in the recessed portion so that the handrail driving device is positioned over the surface of the upper horizontal section and the width of the passenger conveyor is reduced without changing the height of the handrail driving device. The lower auxiliary frame and the inclined section of the main frame also form a recessed portion and a tension device is disposed in the recessed portion so as to be disposed over the main frame, whereby the passenger conveyor is reduced in width by 100-150 mm.

Abstract: A conveyor, in which continuous flights of steps in an endless form are guided by means of guide tracks, and a pair of handrails in an endless form are provided on each side of the flights of steps thereabove and moved at the same speed and in the same direction as those of the flights of steps. This conveyor includes: a pair of main frame bodies each consisting of a vertical member which is formed integrally with upper and lower horizontal members which extend from the top and bottom edges thereof in the horizontal direction, respectively; and transverse beams interconnecting the upper horizontal members of the aforesaid main frame bodies, and connecting members interconnecting the lower horizontal members of the main frame bodies at suitable points along the length of a conveyor. The pair of main frame bodies are positioned on each side of the aforesaid endless flights of steps, respectively.
