AS 1735.5:2015 Lifts, escalators and moving walks
5.5.5.2 Where the skirting of moving walks finishes above the pallets or the belt, the clearance shall not exceed 4 mm measured vertically from the tread surface. Motion of the pallets or the belt in lateral direction shall not cause a gap between the sides of the pallets or the belt and the vertical projection of the skirting.
5.6 Handrail system
5.6.1 General On the top of each balustrade there shall be provided a handrail moving in the same direction and at a speed with a tolerance of – 0 % to + 2 % relative to the actual speed of the steps, pallets or belt under normal operating conditions. A handrail speed monitoring device (see Table 6 m)) shall be provided and shall stop the escalator or moving walk in the event of a hand rail speed deviation of more than –15 % to the actual speed for more than 15 s while the escalator or moving walk is in motion.
5.6.2.1 The handrail profiles and their guides on the balustrades shall be formed or enclosed in such a way that the possibility of pinching or trapping of fingers or hands is reduced. The distance between the handrail profile and guide or cover profiles shall under no circumstances be wider than 8 mm (see b 6 ‘ and b 6 ” in Figure 3, detail W).
5.6.4.1 The lowest point of entry of the handrail into the newel shall be at a distance h 3 from the finished floor level which shall be not less than 0,10 m and not exceed 0,25 m (see Figures 2 and 3).
5.6.4.2 The horizontal distance l 4 between the furthest point reached by the handrail and the point of entry into the newel shall be at least 0,30 m (see Figure 2). If l 4 is greater than (l 2 – l 3 + 50 mm) the handrail shall enter into the balustrade at an angle α of at least 20° measured to the horizontal.
5.6.4.3 At the point of entry of the handrail into the newel a guard shall be installed to prevent the pinching of fingers and hands.
