Description of 21/30403611 DC 2021

1.1 This document specifies the safety requirements for the construction and installation of power operated lifting appliances (referred hereafter as a lift) installed permanently for indoor or outdoor service in wind turbines and intended for access to workplaces on wind turbines by competent persons. A lift serves defined landing levels and may move persons to working positions where they are carrying out work (which could be from the carrier) and has a carrier which is: a) designed for the transportation of persons and goods; b) guided; c) travelling vertically or along a path within 15 degrees maximum from the vertical; d) supported or sustained by rack and pinion or rope traction drive; e) travelling with a speed not more than 0,7 m/s; f) operating ambient temperature range between - 25 °C to + 55 °C. 1.2 This document identifies hazards as listed in Clause 4 which arise during the various phases in the life of such equipment and describes methods for the elimination or reduction of these hazards when used as intended by the manufacturer. 1.3 This document does not specify requirements for: a) operation in severe conditions (e.g. extreme climates, strong magnetic fields); b) noise; c) the use of the lift for erection or dismantling of the wind turbine; d) lightning protection; e) operation subject to special rules (e.g. potentially explosive atmospheres); NOTE Directive 2014/34/EU concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 2014/34/EU. f) electromagnetic compatibility (emission, immunity); g) handling of loads the nature of which could lead to dangerous situations; h) the use of combustion engines; i) hydraulic and pneumatic drive units; j) hazards occurring during manufacturing process; k) the use of lifts in floating wind turbines; l) the use during earthquakes. 1.4 This document is not applicable to: a) builders hoists in accordance with EN 12158-1:2000, EN 12158-2:2000 and EN 12159:2000; b) elevating control stations in accordance with EN 14502-2:2005+A1:2008; c) lifts in accordance with EN 81-20:2019; d) work platforms in accordance with EN 280:2013+A1:2015 and EN 1808:2015 and EN 1495:1997+A2:2009; e) lifts on cranes in accordance with EN 81-43:2009. This document is not applicable to lifts manufactured before the date of its publication.
