BS EN 12312-19:2005+A1:2009EN 12312-19:2005+A1:2009 (E) 4 Introduction This document specifies health and safety requirements, as well as some functional and performance requirements for aircraft jacks, axle jacks and hydraulic tail stanchions intended to be used for servicing

23、and handling of all aircraft types commonly in service in civil air transport. The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical, and practical aircraft jacks, axle jacks and tail stanchions. Deviations from the recommended criteria

24、should occur only after careful consideration, extensive testing, risk assessment and in service evaluation have shown alternative methods or conditions to be satisfactory. This document is a Type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to which hazards, hazard

25、ous situations and events are covered are indicated in the scope of this document. When provisions of this Type C standard are different from those which are stated in Type A or B standards, the provisions of this Type C standard take precedence over the provisions of the other standards, for machin

26、es that have been designed and built according to the provisions of this Type C standard. BS EN 12312-19:2005+A1:2009EN 12312-19:2005+A1:2009 (E) 5 1 Scope This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operatio

27、n and maintenance of aircraft jacks, axle jacks and hydraulic tail stanchions when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft a

28、nd ground support equipment (GSE) manufacturers as well as airlines and handling agencies. This document applies to: all types of aircraft jacks; axle jacks and hydraulic tail stanchions designed to be used at specific jacking points on the aircraft (examples see Annex A). NOTE A tail stanchion type

29、 is intended to be used with one type of aircraft. This document does not apply to aircraft recovery equipment. This document does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3. This Part of EN 12312 is not applicable t

30、o aircraft jacks, axle jacks and hydraulic tail stanchions which are manufactured before the date of publication of this document by CEN. !This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.“ 2 Normative references The follow

36、ack lifting device used to support and/or raise an aircraft via its axles 3.3 hydraulic tail stanchion device used to support an aircraft at its tail during loading and unloading operations 4 List of hazards The list of risks and hazards (see Annex B) is based on EN 1050 and contains the hazards and

37、 hazardous situa-tions, as far as they are dealt with in this document, identified by risk assessment as significant for aircraft jacks, axle jacks and hydraulic tail stanchions and which require action to eliminate or reduce risks. 5 Safety requirements and/or measures 5.1 General requirements 5.1.

38、1 !Aircraft jacks, axle jacks and hydraulic tail stanchions shall conform to the relevant requirements of EN 1915-1, EN 1915-2, EN 1915-3 and EN 1915-4 unless otherwise specified in this standard.“ They shall also conform to the specific requirements of this document. 5.1.2 Stability and strength ca

39、lculations shall be carried out in accordance with EN 1915-2. 5.1.3 Where a pressure relief valve is used for overload protection, it shall not be positioned between the ram and its control device. The pressure relief valve shall be adjusted to the lowest possible value but not exceeding 125 % of th

40、e rated load. 5.1.4 On jacks it shall be possible for the operator to control the lowering speed or stop the lowering at any load up to the rated load, e.g. on manually operated jacks, by a finely controllable valve. 5.1.5 Maximum admissible forces for manual operation and translation of jacks and s

41、tanchions and the methods to measure it are given in Annex C. 5.2 Specific requirements for aircraft jacks and hydraulic tail stanchions 5.2.1 Aircraft jacks and hydraulic tail stanchions shall be designed to enable safe and easy steering, e.g. one steering wheel out of three. 5.2.2 Permanent access

42、 shall be provided on aircraft jacks and hydraulic tail stanchions to enable positioning and adjustment of the upper load support point. Where this is only a ladder, the maximum distance between the fourth tread counting from the top of the ladder and the maximum extended position of the support poi

43、nt shall not exceed 2,0 m. 5.2.3 On power operated aircraft jacks and tail stanchions, emergency stops shall be installed at each operators panel. !They shall meet the requirements in EN ISO 13850:2008, Category 0 or 1.“ BS EN 12312-19:2005+A1:2009EN 12312-19:2005+A1:2009 (E) 7 5.2.4 Adjustable stab

44、ilisers may be considered as equivalent devices to fulfil the requirements in EN 1915-1:2001, 5.7.2. 5.2.5 The lifting system of aircraft jacks shall be equipped so that failure in the lifting device does not generate any hazardous movement of the lifting point/load. 5.2.6 Where more than one jack i

45、s intended to be used to lift an aircraft: failure of one drive shall induce stopping of all the jacks; monitoring of the movement shall be provided, in accordance with EN 1915-1:2001, 5.1; differences in height up to 100 mm shall be automatically corrected and differences in height of more than 100
