ABSTRACT:
A first handrail (2) of the travelator, moving ramp or escalator comprises an endless moving first handrail belt (3) formed as a loop and having a first handhold portion (4) that the passenger can grasp with a hand for support. The first handhold portion (4) has a posterior end (5) posterior in the conveying direction. To support and guide the handrail belt (3), the handrail (2) comprises a first handrail frame (6) having a first side (7). A second handrail (8) is placed after the first handrail in the conveying direction and alongside the conveyor on the same side with the first handrail and extending in a direction parallel to the first handrail (2). The second handrail (8) comprises a second moving endless handrail belt (9) formed as a loop and having an upper second handhold portion (10) that the passenger can grasp with a hand for support. The second handhold portion (10) has an anterior end (11) anterior in the conveying direction. To support and guide the handrail belt (9), the handrail (8) comprises a second handrail frame (12) having a second side (13), which is the side facing the aforesaid first side (7). The first handrail (2) and the second handrail (8) are mounted with a mutual overlap such that the posterior end (5) of the first handhold portion (4) is located substantially side by side with the anterior end (11) of the second handhold portion (10) so that a gap (14) remains between the first and second handhold portions. The first handrail (2) and/or the second handrail (8) comprise/comprises a guide element (15) to prevent the passenger's fingers from getting into the gap (14).
