Tower crane safety on construction sites: A complex sociotechnical system perspective
Tower crane is the lifeline of the construction industry, but tower crane accidents are still too frequent. Despite the significant progress in tower crane safety research, system thinking-based approaches are lacking. The aim of this paper is to analyze tower crane safety from a complex sociotechnical system perspective through implementing both qualitative and quantitative analysis methods. Characteristics of five tower crane safety system components are summarized with a new framework comprised of five system-based levels based on Rasmussen's risk management theory. Fifty-six contributing...
Appareils de levage. Grue de chargement
L'utilisation des appareils de levage fait l'objet de règles, touchant à la fois aux choix, aux vérifications, aux conditions d'utilisation, à la maintenance du matériel et à la formation du personnel. Ce manuel aborde précisément ces règles. Il s'adresse aux chefs d'établissements, chargés de sécurité, formateurs et bien sûr aux conducteurs eux-mêmes.

Grues à tour
Gestion des zones d'interférence et des zones interdites sur les chantiers Compte tenu des contraintes propres à certains chantiers, les grues à tour se trouvent souvent implantées au coeur de zones d'interférence et de zones interdites. L'objet de ce guide est de repréciser les règles de bonne pratique en matière de choix et d'utilisation des dispositifs de sécurité de gestion de ces zones à risque ainsi que les règles en matière de formation du personnel. Il vient compléter la collection...
AHP-based analysis of the risk potential of safety incidents
Case study of cranes in the construction industry The use of data collected from near-miss reports has added value to safety in high-hazard industries such as aviation and the process industry, but this procedure has not yet taken root in construction management practice. Although the management of near-miss reporting systems and the collection of near-miss event reports have been the focus of recent research efforts, the structural analyses of reports have not yet been investigated. This paper reports on a multi-phase research that studied near misses related to crane work and their safety risk...
Analyzing risk factors in crane-related near-miss and accident reports
Learning lessons from near-miss reports is a well-known procedure in various high-hazard industries. The construction industry tends to adopt near-miss management systems, but the procedure is relatively new and has not yet been fully explored or understood. Although the management of near-miss reporting systems in construction has been investigated, no effort appears to have been made to suggest a methodology for technically investigating the content of near-miss reported events. This paper reports a study that implemented both qualitative and quantitative analysis methods for a structured investigation...
Cranes guidance material
This guidance provides information for PCBUs on how to manage the risks at a workplace associated with the inspection, maintenance and operation of cranes and other plant types, including quick hitches for earthmoving machinery. It includes: •guidance on managing risks associated with cranes, including tower cranes and mobile cranes •information sheets on how to manage risks associated with a number of crane variants and attachments, including: •bridge and gantry cranes •powered mobile plant used as a crane •vessel mounted cranes •vehicle loading cranes, and •crane...

Grues à tour
Détermination de la configuration de stabilisation. Prise en compte du vent hors service Les grues à tour, en raison de leur légèreté et de leur hauteur, sont des structures sensibles au vent. Dans certaines conditions et selon l'environnement considéré, des vents violents peuvent mettre en péril leur stabilité et entraîner leur renversement. L'objet de ce guide est de repréciser les régles de détermination du vent hors service, en intégrant la prise en compte des effets de site. Il Un logiciel...
Ergonomic design of crane cabin interior
The path to improved safety Many procedures in the development process of crane cabins today are still based on the specific experience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large proportion of operators. Accordingly, the need for more objective, theoretically justified and consistent models, that will minimize crane operators' biomechanical and visual problems through anthropometric characteristic analysis to improve safety and prevent crane related fatalities and injuries, arises. In that aim we firstly identified the critical...
A ‘normal accident’ with a tower crane? An accident analysis conducted by the Dutch Safety Board
Since cranes and tower cranes are complex installations they constitute critical aspects of safety at construction sites. The risks posed by cranes are specific and should be treated as such. Prior to assessing the impact of management and organizational factors, accident analysis should first start with an analysis of the actual accident process. The Dutch Safety Board conducted such an accident analysis involving a non-mobile, peak less, trolley tower crane. This tower crane collapsed at a Rotterdam building site on July 10th 2008. The results show that the flexibility of the configuration of...
Tower crane incidents worldwide
HSL were requested to identify tower crane incidents that had taken place around the world between 1989 to 2009 and obtain, where possible, the causes of each incident and the tower crane involved. The intention underlying the research was to use the information obtained to assist in advising and guiding the UK tower crane industry to help improve safety.

Cranes in Arboriculture
Towards an Industry Standard This article by David Robinson Tech Cert (Arbor.A), Anderson Tree Care Ltd was originally published in the Arboricultural Association Newsletter issue 145. The author is inviting feedback from members of the industry, who use mobile cranes for tree work. The intention is to encourage people to think about the issues associated with this type of work and to collate information that will be valuable drafting industry guidance on this topic.

Des nouvelles normes ISO élèvent le niveau de sécurité des grues dans le monde
L'exploitation des grues présente toujours un danger potentiel. Les nouvelles normes ISO relatives aux vérifications de ce type d'appareils visent à réduire les risques d'accidents sur les personnes effectuant les manœuvres ou présentes à proximité de ces engins, ainsi que les risques de dommages matériels qu'ils peuvent occasionner. http://www.iso.org/iso/fr/pressrelease.htm?refid=Ref1218
