The wo
14、rk of 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-governm
15、ental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
16、main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
17、Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12488-4 was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 8, Jib cranes. ISO
18、 12488 consists of the following parts, under the general title Cranes Tolerances for wheels and travel and traversing tracks: Part 1: General Part 4: Jib cranes BSISO124884:2004ISO -88421:4)E(4002 iv ISO 4002 All rithgs reresvde Introduction This part of ISO 12488 establishes requirements and gives
19、 guidance and design rules that reflect the present state of art in the field of crane machine design. The rules given represent good design practice that ensures fulfilment of essential safety requirements and adequate service life of components. Deviation from these rules normally leads to increas
20、ed risks or reduction of service life, but it is acknowledged that new technical innovations, materials, etc., may enable new solutions that result in equal or improved safety and durability.

The tolerances given in Tables 5 and 6 of ISO 12488-1: shall apply and shall include tolerances associated with the bogies, equalizers and portal structure. The following ba
27、sic tolerances shall be taken into account: applies to all wheels “in a row”; applies to the overall wheelbase as well as to the internal wheelbases in a bogie or equalizer; applies to the mean bottom wheel surface; it is the accumulated vertical tolerance of all wheels/bogies/equalizers, in connect
