ABSTRACT:
In a man conveyor, a framework includes, as main frame members, beams of a steel material in the form of a letter I or of other shape in cross section, and struts for supporting guide members for endless handrails are rigidly secured to upper edge portions of the beams. The framework of this man conveyor is highly solid and makes possible simplification of the internal structure of the man conveyor.
