BS EN 1494:2000+A1:2008 EN 1494:2000+A1:2008 (E) 5 Introduction !This European Standard is a type C standard as stated in EN ISO 12100-1:2003.“ This standard has been prepared to be a harmonised standard
27、 to provide one means of conforming with the essential Safety Requirements of the Machinery Directive and associated EFTA Regulations. The object of this European Standard is to define rules for safeguarding persons against the risk of accidents associated with the operation of mobile or movable jac
28、ks. The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery should comply as appropriate with !EN ISO 12100“ for hazards which are not covered by this standard. While producing this standard it was assumed that only trained persons operate the lifti
29、ng equipment; the working area is adequately light; harmful materials such as asbestos are not used; components are kept in good repair and working order; by design of the load bearing elements a safe operation of the machine is assured for loads up to 100 % of the rated load and during the tests un
30、der the conditions given by the manufacturer; a negotiation for special uses took place between the user and the manufacturer; components without specific requirements are a) designed in accordance with the usual engineering practice and calculation methods, including all failure modes; b) of sound
31、mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality. 1 Scope This European Standard specifies technical safety requirements and measures for mobile or movable jacks (see 3.6) and associated lifting equipment. This European Standard deals with a
32、ll significant hazards pertinent to mobile or movable jacks and associated lifting equipment when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the signifi
33、cant hazards. This standard applies to lifting equipment (see 3.1) which are mobile or movable and designed to operate under the load, whether operated singulary or in multiples to partially or totally raise and lower loads or vehicles at one or more lifting points (excluding the lifting of persons)
34、 where working under the raised load is not permitted unless additional means of securing the load in position are in place. BS EN 1494:2000+A1:2008 EN 1494:2000+A1:2008 (E) 6 NOTE Associated lifting equipment means lifting equipment which is similar to those defined in 3.1, but which does not fully
35、 comply with these definitions. This standard does not establish additional requirements for power drive by an internal combustion machine; stability of the mobile or movable jacks and associated lifting equipment; operation in severe conditions (e.g. extreme climates, freezer application, strong ma
36、gnetic fields); operation subject to special rules (e.g. potentially explosive atmospheres, mines); supply by electrical networks where the tolerances in voltage, frequency etc. differ from those in the public supplies; static electric problems; handling of loads, the nature of which could lead to d
37、angerous situations (e.g. molten metal, acids, radiating materials, especially brittle loads); hazards occurring during producing and decommissioning; hazards occurring when using the lifting equipment on public roads; wind pressure in and out of use; direct contact with foodstuffs; operation on sea
38、 ships. This standard applies e.g. to the following lifting equipment mechanical jacks with or without claw; hydraulic jacks with or without claw and with or without integrated pump, e. g. hydraulic trolley jacks, hydraulic transmission jacks, hydraulic pit jacks; pneumatic jacks. This standard does
39、 not apply to a) jacks or stabilizers which are permanently fixed to a trailer or a container to support a trailer or container without the tractor-unit; b) hydraulic cylinders which are permanently fixed to the vehicle for tipping and/or tilting parts of it; c) support stands with the possibility f
40、or changing the lift height only without the load; d) hydraulic lifting equipment working with a maximum pressure exceeding 500 bar and where pump and cylinder are not integrated parts of the same equipment; e) jacks that are delivered with road vehicles for helping when a break-down occurs (includi
41、ng delivery of original spare parts).
