1 CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Ian Jones Istanbul – 2011

2  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Plan Originally Planned for two separate amendments :  prA3 – Items to meet the needs of the 3 rd Amendment to the machinery directive.  prA4 – Improvements in the state of the art.

3  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Plan Problem Encountered  prA3 originally to be published, then start work on prA4.  This would have brought prA4 into the same time frame as the full revision of EN81-1/2 into EN81-20/50.  Due to CEN rules it is not possible to work on an amendment to the standard whilst a revision is undertaken.  Therefore prA3 and prA4 were merged, to be issued as a single amendment.

4  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes Content : Machinery Directive changes  Captive fixings for guards removed during regular maintenance not specifically described are added to the assumptions.  Lifts with rated speeds of up to 0.15 m/s are removed from the scope. State of the art changes  Levelling and re-levelling dimensions at floor levels are added.  Control of movement with open doors is elaborated.

5  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes - Assumptions  The introduction and list of assumptions has been amended to include :  The fixing system of guards, which have to be removed during maintenance and inspection, remains attached to the guard or to the equipment, when the guard is removed.

6  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes - Scope  The scope has been amended to exclude the following :  – Lifts with rated speed ≤ 0.15 m/s oTherefore any lifting equipment designed to travel at speeds less than 0.15 m/s is now excluded and classed as a machine, not a lift.

7  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes - Definitions  Stopping accuracy vertical distance between car sill and landing sill at the moment when a car is stopped by the control system at its destination floor and the doors reach their fully open position  Levelling accuracy vertical distance between car sill and landing sill during loading or unloading of the car  Unintended car movement a non-commanded movement of the car with doors open within the door zone away from the landing, excluding movements resulting from loading/unloading operation

8  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Stopping and levelling  Normal stopping of the car at landings and levelling accuracy :  The stopping accuracy of the car shall be ± 10 mm;  A levelling accuracy of ± 20 mm shall be maintained. If, during e.g. loading and unloading phases, the value of 20 mm is exceeded, it shall be corrected.

9  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement  UCM Protection  Lifts shall be provided with a means to stop unintended car movement away from the landing owith the landing door not in the locked position and, othe car door not in the closed position,  Excludes failure of the suspension ropes and the traction sheave of the machine or flexible hoses, steel pipes or cylinder of a hydraulic lift.

10  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement  The stopping element of the means shall act:  on the car, or  on the counterweight, or  on the rope system (suspension or compensating), or  on the traction sheave (e.g. on the sheave directly or on the same shaft in the immediate vicinity of the sheave).  on the hydraulic system (including the motor/pump in up direction)

11  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement The means shall stop the car in a distance:  not exceeding 1,20 m from the landing where the unintended car movement has been detected, and  the vertical distance between the landing sill and the lowest part of the car apron shall not exceed 200 mm, and  the free distance from car sill to landing door lintel, or from landing sill to car door lintel shall not be less than 1,00 m

12  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement

13  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement Characteristics:  Must operate at all loads between full and empty.  Must detect uncontrolled movement away from the floor at the end of the unlocking zone at the latest.  Must stop the car with the equivalent deceleration to that of the normal safety gear

14  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes – Uncontrolled Movement

15  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Changes - Testing Annex D – Tests and Verifications:  The following are added to the list of tests :  Stopping of the car at landings and levelling accuracy (both directions and under all load conditions)  Unintended car movement protection means (empty car up, loaded car down)

16  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Publication  New standards are published as ;  EN81-1: A3:2009  EN81-2: A3:2009  These documents are a fully consolidated text containing ;  EN81 main text published 1998  Corrigendum No.1 published 1999  Amendment A1:2005  Amendment A2:2004  Amendment A3:2009

This is of particular importance with regard to stopping / levelling accuracy and protection from uncontrolled movement with open doors.  Reference to A3 was published in the EU Official Journal (EUOJ) with the “date of cessation of presumption of conformity of superseded standard” based on DOW.  Therefore the present EN81-1 & EN81-2 will remain harmonised and continue to meet the presumption of conformity to the Lifts Directive until June The A3 amendment is seen as improvement to the state of the art.  The existing EN81-1 and EN81-2 standards will be formally withdrawn in June 2011.

19  2005 CEN – all rights reserved CEN TC10 (Lifts, escalators and moving walks) Amendment 3 (A3) to EN 81-1 and EN 81-2 Amendment 3 (A3) Implementation  Due to some problems between the manufactures of the A3 devices and the capacity of the Notified Bodies to approve them, the Commission has agreed to a 6 more months to the date of Cessation of Presumption of Conformity to the existing EN81-1 and EN81-2.  This will allow manufacturers to continue to use the existing standards and meet the requirements of the Lifts Directive until January  CEN/TC10 has also published answers to a series of Frequently Asked Questions, issued by CEN/TC10/WG1. These are aimed at helping manufacturers to better understand the requirements for this new technology.
