Résumé :	Crane accidents are sufficiently frequent and severe in terms of human suffering and financial costs to merit better safety efforts directed towards their reduction. The causes of crane accidents, although varied, usually fall under one or more of the following categories: 1/ Poor design feature; 2/ Operational errors and omissions (including errors committed during planning of operations); 3/ Inadequate and irregular inspection and maintenance of the machines and their associated equipment. Statistics of accidents indicate that the underlying category, responsible for a large proportion of accidents is that of operational errors and omissions. These errors generally originate from inadequate planning, inadequate system of work, poor training standards of the operator and lack of standardisation of machine controls among different makes and models of cranes. These factors surely, represent an area where urgent remedial action is needed to promote the safe use of cranes. Deficiencies in inspection and maintenance of cranes also account for a large number of accidents. Proper inspection and maintenance of a crane are complicated tasks requiring good knowledge and experience in a number of engineering disciplines. Therefore, expert advice and services in this field remain essential elements to the reduction of crane accidents. The number of accidents caused by poor design features is relatively small - metal fatigue remains one of the commonest causes of failure partially related to machine design. Design contribution towards the reduction of crane accidents would, probably, be best achieved by designing and developing safety systems which would prevent the machine operating under adverse conditions, such as overloading or out-of level positioning.
