This document is part 2 of GB/T 39078 "Safety requirements for escalators and moving walks", GB/T 39078 "Escalator and automatic walkways". The Moving Sidewalk Safety Requirements have published the following sections. --- Part 1.Basic safety requirements; --- Part 2.Safety parameters to meet the basic safety requirements. This document uses the redrafting method to modify the use of ISO /T S8103-6.2017 "Escalator and moving walks - Part 6.Satisfaction Safety Parameters for Global Essential Safety Requirements (GESRs). Compared with ISO /T S8103-6.2017, this document has made the following structural adjustments. --- The introduction and scope are numbered for ease of application; The technical differences between this document and ISO /T S8103-6.2017 and their reasons are as follows. --- Regarding normative reference documents, this document has made adjustments with technical differences to adapt to the technical conditions of our country. as follows. ● Replace ISO 14798.2009 with GB/T 20900 which is equivalent to adopting international standards (see 5.2.2, 5.2.3.2); ● Replace ISO /T S25740-1.2011 with GB/T 39078.1-2020 modified to adopt international standards (see 4.1.4, Chapter 6); ● Added reference to GB 16899-2011. ---In Chapter 6, Table 2, some technical differences have been adjusted to the safety parameters and descriptions to adapt to our country's technical regulations. The specific adjustments are as follows. ● In the description 2 corresponding to No. 1, use "5.2.5 of GB 16899-2011 specifies the design load of the support structure (truss)" Instead of "The supporting structure (truss) shall be designed to withstand the loads specified in local regulations and standards (eg. EN115-1 Ref. According to EN1993, A17.1 refers to AISC and BSLJ-EO)”; ● In Description 3 corresponding to No. 1, use "the floor slab of the entrance and exit shall be able to bear the larger value of the load determined by the following requirements. a) Floor slab tread area (m2) multiplied by 6000N/m2; b) 2200N per floor slab. Under the above load, The measured deformation of the floor slab tread shall be no more than 4mm, and the permanent deformation shall be no more than 1mm". "The entrance and exit should be designed to withstand the loads specified in local regulations and standards"; ● In [p1] of No. 2, the vertical distance between the handrail device and the front edge of the carrier device shall not be less than 900mm. should not be greater than 1100mm" instead of "the vertical distance between the handrail and the leading edge of the carrier should not be less than 900mm", The description of [p1] was also coordinated; ● In [p2] of No. 2, use "the armrest device should be able to withstand the static 600N/m lateral force and a vertical force of 730 N/m" instead of "The handrail device shall be capable of withstanding static Lateral force of 585N/m and vertical force of 730N/m”; ● In [p6] of No. 2, use "When the speed of the handrail deviates from the actual speed of the carrier by more than 15% and the duration reaches 5s~ 15s, the escalator should be able to automatically stop running" instead of "when the speed of the handrail deviates from the actual speed of the carrying device greater than 15% and the duration is longer than the specified time, the escalator should be able to automatically stop running”, and delete the description of [p6]; ● In [p10] of No. 2, use "If the inclination angle between the inner cover plate and the horizontal plane is less than 45°, the water between the apron plate and the handrail The horizontal distance should be less than 120mm” instead of “If the inclination angle between the inner cover plate and the horizontal plane is less than 45°, the apron plate and handrail device shall be The horizontal distance between them should be less than 150mm”, which is consistent with the requirements in 5.5.2.6.2 of GB 16899-2011. ● In the description of [p1] in No. 24, "see 5.7.2.1 in GB 16899-2011" is used instead of "for two The definition of the maximum allowable height difference between successive carriers shall be in accordance with local codes and standards”; ● In the safety parameters [p5] and [p6] of No. 25, when the step tread or kick plate is equipped with an insert or a fixing Static load test requirements for some structures to improve safety; ● In the description of [p9] of No. 25, "No permanent deformation of more than 4mm shall be produced on the tread or pedal surface. Steps, pedals or their parts (for example. inserts or fixings) should be connected reliably without loosening", so that the requirements more explicit; ● The safety parameter of No. 25 adds the static load test requirement of the tape, which makes the safety parameter corresponding to this safety requirement more accurate. comprehensive. --- In Appendix A Table A.1, No. 1, No. 2, No. 8~ No. 10, No. 14, No. 15, No. 18, No. 20, No. 22~ Serial No. 24, Serial No. 26~ Serial No. 28, Serial No. 30, Serial No. 32, Serial No. 36, Serial No. 42~ Serial No. 44, Serial No. 48, Serial No. 49 Use Country The data corresponding to the standard replaces the data corresponding to ISO /T S8103-6.2017 Appendix A Table A.1 to conform to my country's national conditions.
