Abstract Tower cranes with overlapping displacement zones require safety devices capable of alerting the operator and if necessary acting on the controls. After a short description of different types of detection, this note reviews and describes the devices currently on the market or in the design stage. A table summarises the situation on 9 sites where such devices are used, and the results of a survey conducted among crane operators are given. The information gathered, the experience acquired and the technological advances in tower cranes and preventive devices should enable manufacturers, users and risk-prevention organisations to draw up draft specifications determining what targets must be achieved in view of the real difficulties on sites and the hazards specific to each installation.
