This document specifies safety requirements: - for tower cranes; - for climbing systems for tower cranes erected from parts. This document applies to tower cranes for construction works, which are either erected by parts or self-erecting cranes, including mobile self-erecting tower cranes. Tower cranes for construction works are exclusively equipped with a hook as load-handling device. Applications when the crane is equipped with a grab or when there is a sudden release of the load, are not covered by this document. This document is not applicable to mobile cranes, mobile harbour cranes, crawler cranes, slewing jib cranes, bridge and gantry cranes, offshore cranes, floating cranes, loader cranes, hand operated cranes or railway cranes. This document deals with tower cranes to be operated at ambient temperature above -20° C. This document deals with significant hazards, hazardous situations and events relevant to tower cranes, it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards (see Annex A). The significant hazards covered by this document are identified in Annex A. This document covers hazards related to the lifting of persons using a climbing system for tower cranes as defined in clause 3.6, 3.7 and 3.8. The lifting of persons by the tower crane itself is not included. The requirements related to Electromagnetic compatibility (EMC), the specific hazards due to external influence on electrical equipment, potentially explosive atmospheres and ionising radiation are not covered by this document. To improve readability, additional requirements for climbing systems are given in Annex E of this document. Additional and specific requirements for mobile self-erecting tower cranes are given in Annex G of this document. This document is not applicable to tower cranes and climbing systems which are manufactured before the date of publication by CEN of this document.

1.1 This document specifies the safety requirements for the construction and installation of power operated lifts attached to cranes and intended for access to workplaces on cranes, by authorised persons. This includes intended use, erection, dismantling, inspection and maintenance. The lift serves defined landing levels and has a load carrying unit which is: - designed for the transportation of persons and goods; - guided; - travelling vertically or along a path within 15 degrees maximum from the vertical; - supported by rack and pinion or suspended by steel wire ropes; - travelling with a speed not more than 1,0 m/s for permanent lifts and not more than 0,4 m/s for temporary lifts. 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 the additional requirements for: - operation in severe conditions (e.g. extreme climates, strong magnetic fields);- - lightning protection; - operation subject to special rules (e.g. potentially explosive atmospheres); NOTE Directive 94/9/EC 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 94/9/EC. - electromagnetic compatibility (emission, immunity); - handling of loads the nature of which could lead to dangerous situations; - the use of combustion engines; - hydraulic drive units; - hazards occurring during manufacturing process; - hazards occurring as a result of being erected over a public road; - earthquakes; - noise (see also Directive on noise emissions from machines used outdoors (2000/14/EC)).
