This document specifies safety requirements: - for tower cranes; - for climbing systems used with the masts of tower cranes; - for the installation of a powered access systems on tower cranes. This document applies to tower cranes for construction work, which are either erected by parts or self-erecting cranes, including mobile self-erecting tower cranes. Tower cranes for construction work are exclusively equipped with a hook as load-handling device. Applications when the crane is not equipped with a hook, or when there is a sudden release of the load, are not covered by this standard. 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 all significant hazards, hazardous situations and events relevant to tower cranes, when used as intended and under conditions foreseen by the manufacturer. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards (see Clause 4). The significant hazards covered by this document are identified in Clause 4. This European Standard covers hazards related to the lifting of persons using a climbing system. 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. This document is not applicable to tower cranes and climbing systems which are manufactured before the date of publication by CEN of this document.

This document is to be used together with EN 13001-1 and EN 13001-2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of cranes by design and theoretical verification. Specific requirements for particular types of cranes are given in the appropriate European standard for the particular crane type. This document covers shafts (axles) in cranes that are not dealt with by other EN 13001 standards (e.g. pinned connections in EN 13001-3-1). It is not intended for axles being part of standard components, e.g. gearboxes, motors ... however those axles shall be designed using load actions from EN 13001-2 and classification parameters of EN 13001-1. NOTE EN 13001-3-7 is under preparation for gears and gearboxes and deals with load actions for axles in gear boxes. The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 4 to 7 of this document are necessary to reduce or eliminate risks associated with the following hazards: - exceeding the limits of strength (yield, ultimate, fatigue); - exceeding temperature limits of material or components. This document is not applicable to cranes which are manufactured before the date of its publication as EN and serves as reference base for the European standards for particular crane types (see Annex C). NOTE prEN 13001-3-8 deals only with limit state method in accordance with EN 13001-1.
