This report presents a procedure for the assesment of Structural Integrity of material lifting and handling machinery, using the methodology of Risk Based Inspection (IBR - Inspeção Baseada em Risco) in order to indentify the parts with high risk of failure. This methodology assesses both probabilities of failure and consequences of failure to identify the critical points; those will be analyzed with priority in future inspection programs. A small hydraulic hoist is used as an example of this procedure applying to big equipments. A detailed strain analysis is carried out for the most important points of the equipment. The strain analysis consider analytic calculations, numeric calculations, experimental measurements and related uncertainly evaluations. In order to calculate the probabilities of failure, the followings damage mechanisms were considered: plastic collapse by excessive loading, fatigue and corrosion. The failure probabilities for each mechanism are calculated and classificated in different levels, as well as failure consequences, that originate different risk levels.
