EN115 “Safety of Escalators and moving walks” Standard Family Part 1 “Construction and Installation” released 2008 Part 1 Amendment released 2009 Part 2 “Rules for the improvement of safety of existing escalators and moving walks” released 2010 Part 3 “Correlation between EN115:1995 and its amendments and EN115-1:2008” published 2009

3 Escalators & moving walks EN115-1
Background EN115-1:2008 revised to comply with and incorporate: Machinery directives (98/37/EC & 2006/42/EC) /42/EC solely valid until Comparison of worldwide escalator codes ISO/TC178/WG Report (agreed upon points from ISO ) Maintenance for escalators and moving walks (EN13015) Interpretations CEN/TC10/WG Risk Assessments (31) of significant hazards (acc. ISO14798)

7 Escalators & moving walks EN115-1
EN philosophy: The purpose of this standard is to define safety requirements for escalators and moving walks in order to safeguard people and objects against risks of accidents during installation, operation, maintenance and inspection work. 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).

8 Escalators & moving walks EN115-1
EN 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

9 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)

10 Escalators & moving walks EN115-1
EN 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

11 Escalators & moving walks EN115-1
EN 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

12 Escalators & moving walks EN115-1
EN 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)

13 Escalators & moving walks EN115-1
EN 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_TC10Neapel bg

14 Escalators & moving walks EN115-1
EN 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
