ČSN EN 17076

This document specifies the requirements of anti-collision devices and systems installed on tower cranes for construction work (as defined in EN 14439:2006+A2:2009) to avoid the risks of collision between several cranes in service, to avoid the risks of collision between a crane in use and fixed obstacles, and to avoid travelling over prohibited zones. It also specifies the requirements for working range limiting devices. Anti-collision devices and systems and working range limiting devices according to this document are safety components. This document defines the safety characteristics and requirements of anti-collision devices and systems intended for installation on self-erecting tower cranes and tower cranes erected from 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. This document deals with all significant hazards, hazardous situations and events relevant to anti-collision devices and systems installed on tower cranes, when used as intended and under conditions foreseen by the manufacturer. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards (see Clause 4). This document is not applicable to anti-collision devices and systems which are manufactured before the date of publication by CEN of this document.
