Escalator acc. EN 115 definition: continuously moving stairway used for raising and lowering passengers. It is not recommended to use escalators as regular staircases or emergency exits. The same safety requirements for all types of escalators (commercial and public use). 7 Escalators & moving walks EN115-1 EN115-1 2008 clause 3, terms and definitions: Nominal speed: Speed in direction of the moving step, pallets or belt under no load conditions Rated speed: Speed to move the escalator / moving walk under rated load conditions Rated load: Load at which the equipment is designed to move passengers (capacity) Structural load: Load at which the escalator / moving walk supporting structure is designed Brake load: Load at which the brake system is designed to stop the escalator / moving walk Clear definition of electrical safety systems / devices; safety circuits /fail safe circuits 8 New structure of EN 115-1 2008 Clause 5, Safety requirements Electric installation (5.11) Machinery spaces (5.8) Balustrade (5.5) Drive unit (5.4) Step band (5.3) Handrail system (5.6) Supporting structure (5.2) General (5.1) Fire Protection (5.9) Transportation (5.10) Protection against electric faults – controls (5.12) Landing (5.7) 9 Escalators & moving walks EN115-1 EN115-1 2008 Clause 5 main agreements: Supporting structure deflection (1/750) for all Deceleration rate for braking under 1m/s2 Factor of safety 5 (with 5000 N/m2) for whole drive system between brake to step/pallet Definition of the radius of curvature depending on the speed and inclination 10 Escalators & moving walks EN115-1 EN115-1 2008 Clause 5 main agreements: Balustrade arrangement: - measures shall be taken to discourage people from climbing on the outsides - access restriction device and anti-slide device 11 Escalators & moving walks EN115-1 EN115-1 2008 clause 5 main agreements: Entrapment between skirts and steps Parameters defined : – deflector guard – maximum skirt deflection – gap between skirts and steps – friction factors between skirt / shoes (reference material) 12 Escalators & moving walks EN115-1 EN115-1 2008 clause 5 main agreements: Additional torsional test for steps and pallets Horizontal step treads with a tolerance of 1° in the user carrying area Secure foothold at tread surfaces (e.g. acc. to DIN 51130) Pallets width limited to 1,65m (up to 6°) glogau/hwa/Normen/Präsentationen/CEN_TC10Neapel28.11.03bg 13 Escalators & moving walks EN115-1 EN115-1 2008 clause 5, agreements electric: Missing step / pallet device: To detect a missing pallet / step prior to the gap emergency from the comb line Inspection cover/ floor plate switch: Operation in inspection mode after removal Brake lift monitoring device 14 Escalators & moving walks EN115-1 EN115-1 2008 clause 5, agreements electric: Handrail speed monitoring device Stop switch for emergency situation Review of positioning 15 Escalators & moving walks EN115-1 New chapter 6 for verification proof 16 Escalators & moving walks EN115-1 EN115-1 2008 Annex A normative Building Interfaces: Clear description of the surrounding e.g.: Where it is possible for people to come into contact with the outer edge of a handrail at a landing and can be drawn into a hazardous situation, such as toppling over a balustrade, appropriate preventative measures shall be taken. 17 Escalators & moving walks EN115-1 EN115-1 2008 normative annexes Electrical systems: Annex B Electronic components - Failure exclusion Annex C Drafting and assessing fail safe circuits Annex D Testing of fail safe circuits containing electronic components 18 Escalators & moving walks EN115-1 EN115-1 2008 Annex G normative: Caution Signs - Push chairs are not permitted 19 Escalators & moving walks EN115-1 EN115-1 2008 Annex H informative : Guidelines for selection and planning of escalators and moving walks revised: Maximum capacity determined based on people counting Escalators or moving walks for public transport 20 Escalators & moving walks EN115-1 EN115-1 2008 Annex I normative: Prohibited use of trolleys and baggage carts on escalators Safety requirements and safety parameters for shopping trolleys and baggage carts on moving walks defined (Suitably designed according to EN1929-2 and EN1929-4) 21 Escalators & moving walks EN115-1 EN115-1 2008 Annex informative slip/sliding properties Annex J Definition of anti-slip properties for steps, pallets, comb plates and landing plates Annex K Determination of sliding properties of footwear on skirtings 22 2009 Amendment 1 - PESSRAE Escalators & moving walks EN115-1 Replaced EN 954-1:1996, Safety of machinery EN ISO 13849-2:2003, Safety of machinery New reference Programmable electronic systems in safety related applications EN 62061: Functional safety of safetyrelated electrical, electronic and programmable electronic control systems 2009 Amendment 1 - PESSRAE Escalators & moving walks EN115-1 Replaced New table 6 Escalators & moving walks EN115:1 EN115-1 => EN115-2 Thank you for your attention 25
