BS EN 17076:2020 pdf free.Tower cranes – Anti-collision systems – Safety requirements.
BS 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 anticollision devices and systems intended for installation on self-erecting tower cranes and tower cranes erected from parts. In particular: 一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 anticollision 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. An anti-collision device and the therein used safety related parts of the control system shall perform at least the following safety function: Limitation of a static or dynamic changing working range. This safety function is intended to reduce the risk of a collision of all possible parts of interfering cranes (e.g. hoist rope against jib or counter-jib of an adjacent crane) or the risk of entering into a prohibited zone. Adapted to the characteristics of the cranes drives, the anti-collision device has to give control commands to slow down and stop the motion prior to reaching the actual stop limit.
