7、foreword This British Standard has been prepared under the direction of the Aerospace Standards Policy Committee. It is identical with ISO 6966:1993 Aircraft Basic requirements for aircraft loading equipment published by the International Organization for Standardization (ISO). The Technical Committ
8、ee has reviewed the provisions of ISO 4116:1986 and ISO2328:1993, 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 purport to include all the necessary provisions of a contract. Users of
9、British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

21、 working surface at the same time. 6.2.6 On open cab vehicles with passenger seat(s), a hip guard shall be provided on the outside edge of the outside seat(s) with a minimum height of8cm(3in) above the seat surface. 6.3 Controls 6.3.1 Controls and warning lights shall be grouped and located so as to
22、 be convenient to the operator from his normal operating station or stations. Where there is more than one station, interlocks should be provided at each station to render inoperative the controls of all other stations. 6.3.2 Controls and warning lights shall be properly and permanently identified,
23、preferably by pictograms (see ISO 7000).BSM74:1994 2 BSI 01-2000 6.3.3 All operational controls shall move in the direction of travel for the function which they control and shall be of the deadman type, unless the control is set to achieve a function to permit the users to accomplish another task.
24、In these cases, such set controls shall be detented or similarly locked into the operating position to prevent inadvertent deactivation or reversing. Such controls shall be readily available to the operator(s). Operating controls only used in emergencies need not meet this requirement. 6.3.4 Hand an

26、ided with a nonslip material. 6.3.6 Controls and controlling circuits shall be designed in such a manner that failure within a control or its circuitry will not introduce an unsafe operating condition. 6.3.7 Conventional automotive driving controls shall be used where possible. 6.4 Stability 6.4.1 S
27、elfpropelled type units equipped with power-actuated stabilizers shall have an operator warning device to indicate when the stabilizers are not in the stowed position. 6.4.2 Lift type units exposed to blast, wind and/or irregular surfaces, shall be equipped with stabilizing devices, which preclude t
28、he unit overturning when exposed to wind or blast up to120 km/h (65 kn) in the elevated position. 6.4.3 The stability outlined in 6.4.2 shall determine at which point during elevation the stabilizing devices will be necessary. A safety device shall be provided to ensure this elevation is not exceede
29、d unless stabilizing devices are extended and/or engaged. 6.4.4 Retraction of the stabilizing device shall not be possible under normal or emergency conditions until the unit has been lowered to within the stability requirements outlined in 6.4.2. 6.4.5 Stabilizer activating devices shall be located
30、 so as not to expose the operator to personal injury. 6.4.6 An interlock shall be provided to prevent driving the vehicle when stabilizers are not fully retracted. 6.4.7 Emergency-raising stabilizer controls shall be provided and shall be so located as not to expose the operator to injury. 6.4.8 Sta

32、 shall be capable of withstanding blast or ambient winds as specified in 6.4.2, and shall be installed so that the doors, when open, do not create a personnel injury hazard. 6.6 Components All components that exceed36 kg (80 lb) or that exceed15 kg (33 lb) where only one person has access to the uni
33、t for handling, shall have provisions for attaching lifting or handling devices. 6.7 Machinery guards Sprockets, gears, chains, belts, fans and pulleys, or other nip or pinch point hazards which are not protected by vehicle structures or covers shall be guarded. 6.8 Fuel and fluid replenishing 6.8.1
34、 Fuel lines shall be secured with a minimum of5 cm (2 in) clearance to exhaust and electrical systems. 6.8.2 Fuel tank(s) shall be located and installed so that any overflow during filling, or any leakage from the tank, lines or fittings, will not impinge on the engine, exhaust, electrical system or
35、 other ignition sources or enter the operators compartment. Consideration should be given to avoiding spilled fuel making work or access surfaces slippery. 6.8.3 Fuel tanks shall be located for maximum protection from collision damage. 6.9 Exhaust 6.9.1 Internal combustion engines shall be fitted wi
36、th a baffle-type muffler. 6.9.2 The exhaust system, beyond the manifold, shall be supported at least7,5cm (3 in) clear of combustible materials, excluding flexible mountings, and at least5cm (2 in) clear of fuel, hydraulic and electrical system parts and shall not be subject to drippage of fuel, oil
37、 or grease. 6.9.3 The surface and the discharge of exhaust systems shall be located so that they will not expose employees and/or materials to injury or damage. 6.10 Visibility 6.10.1 Vehicle operators shall have clear and unimpaired visibility when operating the unit.
