On elevators in public places, there are many children chasing and playing. Although many escalators are hung with eye-catching signs such as "no climbing and playing" and "children must ride under the supervision of adults", the installation of anti climbing devices for elevator handrails will also reduce the risk of accidents.
Therefore, when it is more than 12.5cm adjacent to the wall, blocking devices shall be installed at the upper and lower ends of the escalator or moving sidewalk to prevent personnel from entering the outer cover plate area, resulting in falling and other accidents.
According to the requirements of the Technical Supervision Bureau and the relatively new requirements of the new national standard of escalators: in order to prevent personnel from falling, anti climbing devices shall be installed on the outer cover plates of escalators and moving sidewalks. If there is a risk of personnel falling, appropriate measures shall be taken to prevent personnel from climbing on the outside of the handrail device. Do not set if there is no possibility of climbing, such as leaning against the wall or having been set to prevent entry (counter, barrier, etc.) only if there is the possibility of entering or falling after entering, it is necessary to set handrail device and apron. The anti climbing device is located at (1000 ± 50) mm above the ground plane, and the lower part intersects with the outer cover plate, The extension length parallel to the direction of the outer cover plate shall not be less than 1000mm, and there shall be no foot step within this length range.
