7、T+00:00 2006, Uncontrolled Copy, (c) BSI BS M 81:1995 ii BSI 11-1999 National foreword This British Standard has been prepared by Technical Committee ACE/57. It is identical with ISO 6968:1994 Aircraft Wide body aircraft lower deck container/pallet loader Functional requirements, published by the In
8、ternational Organization for Standardization (ISO). Cross-reference. The Technical Committee has reviewed the provisions of ISO 4116:1986 to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not
9、purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fro

23、81:1995 2 BSI 11-1999 4.4 The forward end of the front platform shall have, at its right-hand side, provisions to accommodate 1 780 mm (70 in) wide container-hold doors. These provisions may either consist of a retractable extension to the front platform, or may be met by a front platform of adjusta
24、ble width. 4.5 Several aircraft have flap track fairings which project from the trailing edge of the wing. If the loader, owing to its overall width, has to pass under the wing for approach to or removal from the rear lower deck compartment, the height of any portion likely to pass under the flap tr
25、ack fairings shall, for safety reasons, not exceed 2 800 mm (110 in). Installations, if any, extending beyond this limit shall be foldable or retractable. 4.6 The surfaces of both platforms shall allow for longitudinal and lateral movement of the containers/pallets. Longitudinal movements shall be e
26、ffected by means of a powered system. 4.7 The loader shall be designed for powered end and side loading of containers/pallets. 4.8 The powered system shall be able to drive containers/pallets at a speed of approximately 0,3 m/s (60 ft/min). Adjustments to a reduced speed shall be possible. 4.9 The f
27、ront platform shall be adjustable to changes in aircraft pitch, roll and height. NOTE 1It is recommended that the front platform be capable of being attached to the aircraft so as to compensate for changes in aircraft attitude. Users of this International Standard are advised that proprietary rights
28、 apply to devices conforming to this recommendation. The patent holder has agreed to negotiate licences on terms and conditions defined in a statement that is available upon request from the ISO Central Secretariat. 4.10 The front platform shall be designed not to interfere with the opening and clos
29、ing of the aircraft doors. 4.11 Removable guide rails, fixed on the main platform and adjustable on the front platform to the following container/pallet widths: a) 1 534 mm (60,4 in); b) 2 235 mm (88 in); c) 2 438 mm (96 in); shall be provided as follows: a) Front platform Along the whole length of
30、both sides of the platform to exactly guide load units into the aircraft. They shall be adjustable laterally to align with the appropriate in-aircraft guides; b) Main platform 2 438 mm (96 in) apart along both sides of the platform. The guide rails shall consist of two sections able to be operated i
31、ndependently. All four sections shall automatically extend when the main platform starts moving upward and remain in this position. When the main platform is being lowered and it reaches the height of 1 520 mm (60 in) from the ground, it shall be possible for the operator to control the retraction o
32、f the guide rails. 4.12 Automatic container/pallet stops shall be provided as follows: a) Front platform At the end adjacent to the main platform. These stops shall rise at the moment the main platform starts moving down and shall be retracted when the upcoming main platform is level with the front
33、platform; b) Main platform At both ends. Ramp side stops shall automatically retract as the platform reaches a full down position and extend, when the platform rises. The stops at the end adjacent to the front platform shall be extended in the down position and retract when the platform lines up wit
34、h the front platform. The location of these stops shall take into account the container overhang. 4.13 All stops shall have a minimum height of 51 mm (2 in). 5 Platform operation and loading 5.1 It shall be possible to adjust the container/pallet in a lateral direction on the front platform. 5.2 Pla
35、tform elevating systems shall be able to hold both platforms at maximum height with full specified continuous lift capacity with no noticeable height decrease for 30 min with and without the engine running. 5.3 Both the front and main platform elevating mechanisms shall incorporate safety features t
36、o prevent sudden collapse in the event of system failure. 5.4 Load movement in and out of the aircraft shall be carried out by one person (operator). The unit shall be capable of being positioned and operated by one person. The operator shall be able to open the aircraft door from the front platform
37、. 5.5 The time taken for the main platform to reach maximum height from the lowered position and vice versa, i.e. one complete cycle, shall be less than 35 s.

38、M 81:1995 BSI 11-19993 5.6 The front platform shall be accessible from the ground at all times. 5.7 It shall not be possible to alter the height of either platform when containers/pallets are bridging the platforms. 6 Mobility and stability 6.1 The unit shall be capable of being driven at speeds up
39、to 16 km/h (10 mile/h) for at least 3 km (2 miles). The unit does not require the capability of being driven when loaded. 6.2 Power steering shall be provided. 6.3 The unloaded unit shall be capable of starting from rest up a 3 incline under its own power. 6.4 The unit shall be capable of turning wi
40、th a swept radius of less than 12,2 m (40 ft). 6.5 For the final safe positioning at the aircraft door a slow positive non-jerking speed is required. 6.6 Power-operated stabilizers shall be installed in order to provide for the stability required for loading/unloading operations and to unload the wh
41、eel axles. In case of power failure, manual retraction of the stabilizers shall be possible. 6.7 The unit in the raised position with stabilizers extended shall be safe in wind velocities up to 130 km/h (80 mile/h). In the lowered position, the loader shall remain stable in wind velocities up to 190
42、 km/h (120 mile/h). 6.8 It shall not be possible to activate the transfer system and to raise the main platform from the full down position if the stabilizers are not extended; to drive the loader when the stabilizers are extended; for stabilizers to collapse in the case of system failure. 7 Control
43、s 7.1 All controls necessary to move and position the loader shall be located in the driver position. 7.2 An electrical control panel shall be provided to allow control of both platforms and complete loading/unloading processes from the front platform. This should be located so that it can be used s
44、imultaneously with the in-aircraft control systems. 7.3 Ample lighting is required for night operations and to illuminate the platforms and close surroundings. 7.4 Normal system warning and indicator lights shall be provided.
