Foreword
This document (prEN 14439:2014) has been prepared by Technical Committee CEN/TC 147 “Cranes -
Safety”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14439:2006+A2:2009.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
CEN/TC 147/WG 12 "Cranes – Tower Cranes" has developed a revision of this document, which differs from
EN 14439:2006+A2:2009 as follows:
Integration of mobile self-erecting tower cranes, including introduction of a new dedicated Annex H
integration and rules for application of EN 13001 series of standards
modification of clause 5.2
integration and rules for application of EN ISO 13849-1
modification of Annex E – Climbing system
addition of a new annex concerning calculation of the maximum load effect at the load case wind coming
from all directions
addition of a new annex concerning calculation of standards values of the limit design stress range
addition of a new annex concerning the requirements on a tower crane for installation of a powered
access system
To select a suitable set of crane standards for a given application see Annex J.
NOTE Some of the standards listed are in preparation.

Introduction
This is a harmonised European Standard to provide one means for tower cranes to conform with the relevant
Essential Health and Safety Requirements of the Machinery Directive 2006/42/EC modified.
This European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for cranes that
have been designed and built according to the provisions of this type C standard.
prEN 14439:2014 (E)
1 Scope
This European Standard specifies safety requirements:
for tower cranes and
for climbing systems used with the masts of tower cranes for which they have been designed. They are
classified as external or internal systems.
This European Standard 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.
This European Standard 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 European Standard 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 European Standard
specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards
(see Clause 4).
The significant hazards covered by this European Standard are identified in Clause 4.
This European Standard does not cover hazards related to:
the lifting of persons by the tower crane itself.
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 European Standard.
This European Standard covers hazards related to the lifting of persons using a climbing system.
This European Standard is not applicable to tower cranes and climbing systems which are manufactured
before the date of publication by CEN of this European Standard.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in in EN ISO 12100, ISO 4306-1 and
ISO 4306-3 and the following apply.
Note 1 to entry: Additional definitions for climbing systems and powered access systems are given in Annex G and
Annex I.
3.1
rated capacity
load, having mass m , which is lifted by the crane and suspended from the fixed load-lifting attachment(s).
NL
Mass m is the sum of the pay load m and the non-fixed load-lifting attachment(s) m :
NL PL NA
m = m + m .
NL PL NA
The maximum net load that the crane is designed to lift for a given crane configuration and load location
during normal operation.
3.2
tower crane
power-driven slewing jib type crane with the jib located at the top of a tower which stays approximately vertical
in the working position
Note 1 to entry: A tower crane is equipped with means for raising and lowering suspended loads and for the
movement of such loads by changing the load-lifting radius, travelling of the load, slewing or travelling of the complete
appliance. Some tower cranes perform several, but not necessarily all of these movements.
3.2.1
tower crane erected from parts
tower crane assembled from component parts where the design of the crane allows the crane to remain in the
erected position in out-of-service conditions and to be dismantled for movement to another site
3.2.2
self-erecting tower crane
tower crane which is transported to site and mostly assembled without use of a separate lifting appliance,
where the design of t
