EN 14439:2025

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. This document is applicable to tower cranes to be operated outdoors at ambient temperature between -20 °C and +40 °C. This document is not applicable to tower cranes, which are permanently installed on a yard or integrated in a manufacturing process, resulting in a significantly different classification of the crane and its mechanisms, or which are equipped with a grab or when a sudden release of the load is intended, resulting in significantly different load actions and number of stress cycles. 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 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 3.6, 3.6.1 and 3.6.2. The lifting of persons by a 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 requirements for mobile self-erecting tower cranes are given in Annex B 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.
