scope:

This European Standard specifies the functional requirements of anti-collision devices and systems installed on self-erecting tower cranes or tower cranes assembled from component parts to avoid the risks of collision between several cranes in use, between a crane in use and fixed obstacles, and over prohibited zones. It applies to anti-collision devices manufactured after the publication of this standard. This document defines the safety characteristics and requirements of anti-collision devices and systems intended for installation on self-erecting tower cranes or tower cranes assembled from component parts. In particular: - performance level; - information to be provided by the sensors installed on the crane; - operation, particularly in the event of failure, override and free jib slewing states of a crane; - type of communication between devices; - information for the crane operator and outside indicator. It also specifies the requirements for marking the device or the system and the content of the instruction for use.
