AS 1735.5.4:2019 Lifts, escalators and moving walks
2 Placement requirements
A) In case of a free-standing guiding barriers or traffic columns, they shall be positioned in a minimum horizontal distance (radius) of 500 mm from any point of the handrail, and outside of the centre line of the handrail (see Figures 1 a)/b) on Page 3, Figure 8 on Page 7).
B) This minimum distance may be reduced to 300 mm, provided that the guiding barriers or traffic columns are positioned outside of the centre lines of the handrails and an additional barrier is installed between the guiding barriers or traffic columns and the vertical centre line of the balustrade newel (see Figures 2 a)/b) on Page 3, Figure 8 on Page 7). The additional barrier shall have a lateral distance between 80 mm to 120 mm of the handrail outer edge and shall close at least the area between the actual lowest point of the handrail entry into the newel (h 3 , see 5.6.4.1 of EN 115-1:2008+A1:2010) and the balustrade decking profile and shall have filled inlets with gaps < 25 mm with no pinching risk (see Figures 6 a)/b)/c)/d) on Page 5).
C) Further reduction to 180 mm is permitted, as long as the guiding barrier or traffic column is positioned outside of the outer edge of the handrail and an additional barrier is installed between the guiding barrier or traffic column and the vertical centre line of the balustrade newel (see Figures 3 a)/b) on Page 4, Figure 8 on Page 7). The additional barrier shall have a lateral distance between 80 mm to 120 mm of the handrail outer edge and shall close at least the area between the actual lowest point of handrail entry into the newel (h 3 ) and the balustrade decking profile and shall have filled inlets with gaps < 25 mm with no pinching risk (see Figures 6 a)/b)/c)/d) on Page 5).
D) A reduction of the horizontal distance to 100 mm (identical to the minimum value of h 3 ) is permitted, only if the guiding barrier or traffic column is of a round shape and is positioned outside of the outer edge of the handrail and an additional barrier is installed between the guiding barrier or traffic column and the vertical centre line of the balustrade newel (see Figures 4 a)/b) on Page 4, Figure 8 on Page 7).
