5.1.2 Shape of the components of anti-collision devices For all the components of the anti-collision device installed near the control station EN 13557:2003+A2:2008, 5.2.1.9 shall apply. 5.1.3 Requirement for the mechanical installation of the components of anti-collision devices on the crane When the anti-collision device requires having component(s) mechanically installed on the crane, they shall be designed to be assembled and fixed in such a way to prevent errors of fitting, to prevent them from inadvertent movement and from falling during normal operation. The mechanical installation shall not affect the tower crane functions. 5.1.4 Crushing or shearing hazards between moving parts When a component of the anti-collision device presents moving parts when installed on a crane, means of guarding shall be provided in order to avoid any crushing or shearing hazards of the persons accessing the crane with the moving parts. 5.1.5 Controls When a component of the anti-collision device presents a means of control, it shall conform to EN 13557:2003+A2:2008. 5.1.6 Cableless means of communication When the anti-collision device is using a cableless means of communication for a safety function then this safety function shall fulfil the requirements specified in 5.1.7.5.1.7 Safety functions 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-ib 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. This safety function and the therein used safety related parts of the control system shall fulfil at least the Performance Level PL C, category 2 according to EN ISO 13849-1:2015. NOTE An emergency stop initiated at the crane affects only the crane at which it has been released. This information can be transferred to the ACD but does not initiate a reaction at other cranes, which are part of the ACS. In case of transmission of data related to safety functions between the ACDs over a server and/or processing of the data on this server, this server should be a safety component and considered at the calculation of the Performance Level. 5.1.8 Indicating functions The anticollision shall be designed with indicating devices to inform the crane operator (see 6.8) and the jobsite environment (see 6.9). 5.1.9 Operating computation To manage potential interfering parts and/or entering in prohibited zone, the anti-collision device computing shall take into account all the relevant parameters, e.g. accuracy of sensors, control system response time.5.2 Information requested to operate the anti-collision device and system 5.2.1 General Information provided by sensors which may be part either of the anti-collision device or of the tower crane shall fulfil the requirements of this document. Depending on the design of the ACS respectively the ACD, some or all of the information given in 5.2.2 to 5.2.6 shall be provided. Such information shall comply with the requirements given in 5.2.2 to 5.2.6. NOTE The accuracy includes all errors combined due to the accuracy of the sensor and the inaccuracies of the driveline. 5.2.2 Updating time For the smooth operation of the anti-collision device, the information provided by the sensors shall have a maximum updating time of 200 ms. 5.2.3 Crane response time The anti-collision device shall be designed to operate with a crane designed to have a maximum response time of 500 ms.
