9、member bodies). The work 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, govern
10、mental 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 of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Dir
11、ectives, Part 2.The 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 bod
12、ies casting a vote.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 27471 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicle

14、 a self-propelled container/pallet loader capable of raising air cargo unit load devices (ULDs) to the upper deck of very large capacity freighter (VLCF) aircraft and also to the main deck of any main-line freighter aircraft.This International Standard does not intend to provide all the design requi
15、rements applicable for aircraft upper-deck loaders. Other requirements can be found in separate standards which are also applicable: ISO 4116 specifies the additional requirements applicable for conveying surfaces of aircraft ground support equipment intended for handling and loading of baggage and
16、cargo ULDs; ISO 6966-1 and ISO 6966-2 specify, respectively, the general and safety-related requirements applicable to all aircraft ground support equipment.The requirements of this International Standard were determined based on generally recognized assumptions as to:a) the normally intended use of
17、 aircraft ground support equipment, when used on the ramp of international civil airports in order to handle, service or maintain civil transport aircraft;b) the environmental (surface, slope, weather, lighting, operating rules, traffic infrastructure, staff qualification, etc.) conditions prevailin
18、g on the ramp area of the majority of international civil airports.It is assumed that the manufacturers of aircraft upper-deck loaders define in the relevant documentation the specifically intended conditions of use and environment for each model, and that the purchasers systematically review their
19、own specific conditions of use and environment in order to determine whether those stated are adequate, or negotiate with the manufacturer appropriate modifications to ensure they are.This International Standard does not specify requirements applicable to: any adapters or ancillary/supplemental equi
20、pment additions to in-service main-deck loaders in order to allow their occasional upper-deck use; any main-deck loaders fitted with optional access to upper-deck height of the front platform only (ISO 6967:2006, 4.8).2 Normative referencesThe following referenced documents are indispensable for the

34、ce platform capable of operating between 2 590 mm (102 in) to at most 2 900 mm (114 in) (see 4.1.4 and 4.1.9) and 8 380 mm (330 in) above the ground, which is positioned at the applicable aircraft door and shall remain at this position during the complete loading/unloading operation;b) optionally, a
35、n intermediate platform shuttling between the aircraft interface and main platforms;c) a main platform for up and down movement between 480 mm (19 in) and either 8 380 mm (330 in) or, if an intermediate shuttling platform is provided, 5 540 mm (218 in) above the ground.4.1.3 The overall dimensions o
36、f the unit shall be kept to a minimum consistent with its intended use and performance. See 4.5.6 for turning-radius requirements.4.1.4 The overall height of the entire unit when being driven should not exceed 4 000 mm (157 in), in order to be compatible with usually encountered airport infrastructu
37、re. See 4.1.9 for foldable guard-rails if needed.It is recommended not to exceed this value. Loaders may however exceed it, subject to verification of available height clearances in the intended movement zone at the airport of use, but should not in any event exceed 5 000 mm (197 in), in order to pr
38、event the risk of interference with the aircraft wing trailing edge while positioning at main-deck doors aft of it.4.1.5 The loader shall simultaneously support, at their maximum gross mass, at least: one 2 438 mm 3 175 mm (96 in 125 in) ULD in either direction on the aircraft interface platform; IS

40、than one ULD position, the aircraft interface platform may be smaller than one position. However, in such a case, an increased hazard may result from personnel working near to the aircraft door area being too close to the platforms edge: a retractable safety barrier (see 5.9) shall then be provided
41、aft of the platform as a guard-rail across the whole width whenever the adjacent platform is not level with the aircraft interface platform.4.1.6 The aircraft interface platform shall be adjustable to changes in aircraft attitude:a) pitch and roll: within a minimum range of 2 (3,5 %);b) height: with
42、 an accuracy of 6 mm (0,25 in).4.1.7 The aircraft interface platform shall be designed not to interfere with the opening and closing of the aircraft doors, either from a safe position on the loader or from inside the aircraft, up to a door width of 4 320 mm (170 in), with no less than 100 mm (4 in)
43、clearance on each side. All component parts that may come into contact with the aircraft should be covered with protective padding, e.g. rubber tube or “D” section. See Reference 12 for information on protective materials.4.1.8 The aircraft interface platform shall include adjustable side guides tha
44、t can be aligned with those of the aircraft and locked into position. The platform should be: either overhanging by at least 305 mm (12 in) forward of the front vertical end of the chassis;or fitted on its forward edge with a telescoping element with rollers, in order to bridge the gap to the aircra
45、ft door sill where this is not achieved by an aircraft cargo door sill folding-out element.The telescopic element extension, if applicable, shall have a minimum 3 300 mm (130 in) width, be powered and extend no less than 305 mm (12 in) forward of the fixed platform edge. It shall not be possible to
46、lift or lower the platform, except for small adjustments to aircraft door sill height, prior to the telescopic element being fully retracted.4.1.9 Fixed safety guard-rails (side panels) shall be fitted to both outer sides of the aircraft interface platform and shall have a minimum height of 1 100 mm
47、 (43 in), in accordance with ISO 14122-3, up to 1 400 mm (55 in). Guard-rails shall be adjustable to fully close any gap between the loader and the aircraft, including when the platforms telescopic element (see 4.1.8), if provided, is fully extended, and on the aircraft door opening.Safety guard-rai
48、ls/side panels shall be lockable in either deployed or stored position and provide a continuous kick plate at least 150 mm (6 in) high. They should preferably be filled with continuous material.When the guard-rails are higher than 1 100 mm (43 in), a continuous hand rail should be provided along the
49、 inner sides at a 1 000 mm (40 in) height. Where necessary, to meet the overall driving height objective (see 4.1.4), the top part of the guard-rails may fold down in the driving mode. In such a case, the top part of the guard-rails shall fold down inward, fail-safe mechanical locking shall be provided for each guard-rail section in the deployed position, and the drivers position shall remain protected.4.1.10 Where an intermediate platform is provided and is authorized for use in lifting personne
