worldwide federation of national standards bodies (ISO member bodies) The work o f preparing International Standards is normally carried out through ISO technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters o f electrotechnical standardization The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part In particular the different approval criteria needed for the di fferent types o f ISO documents should be noted This document was dra fted in accordance with the editorial rules of the ISO/IEC Directives, Part (see www.iso.org/directives) Attention is drawn to the possibility that some o f the elements o f this document may be the subject o f patent rights ISO shall not be held responsible for identi fying any or all such patent rights Details o f any patent rights identified

On sites where there is more than one tower crane, which are not equipped with anti-collision devices, and there is a possibility o f collision between cranes, a person, designated as the crane co-ordinator (see 5.9), and the crane operator shall coordinate the sequence of crane movements to prevent collisions Any corresponding instructions from the crane co-ordinator to the crane operators shall be via the respective signallers In such circumstances the signallers shall obtain the agreement of the crane coordinator be fore carrying out any operation Where tower cranes inter-arc, a vertical distance shall be maintained to prevent collisions This distance shall be either a) a minimum clearance of m, or b) a minimum clearance o f 600 mm when taking into account the manu facturer’s deflections, only when full details are available from the manufacturer The positioning o f the crane and components in the out-o f-service condition, as specified by the manu facturer’s instructions, shall be such that no collisions can take place [see 10.4 b)] Cranes should, where possible, be sited such that collision hazards are eliminated or minimised 4.2 Control of the crane operation ISO 12480-1:1997, 4.2, shall apply 4.3 Contractual considerations It is unlikely that tower cranes will be used in “contract operation” (i.e where an “employing organisation” enters into a contract with a “user organisation” that will undertake the work on their behalf) I f required, ISO 12480-1:1997, 4.3, shall apply Selection, responsibilities and minimum requirements of personnel 5.1 General ISO 12480-1:1997, 5.1, shall apply 5.2 Duties of the person appointed to control the crane operation (the appointed person) ISO 12480-1:1997, 5.2, shall apply In the interests o f sa fety the appointed person shall arrange the li fting programme such that no operator has to be in attendance at the control station or actually operating the crane for an unreasonably long period, taking into account environmental conditions The operator shall have breaks from the working activity in line with other personnel on the site 5.3 Crane operator ISO 12480-1:1997, 5.3.1 and 5.3.2, shall apply © ISO 2016
