This European Standard shall be given the status of a national standard, either by publication of
23、 an identical text or by endorsement, at the latest by September 2010, and conflicting national standards shall be withdrawn at the latest by September 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall
24、 not be held responsible for identifying any or all such patent rights. This document supersedes EN 1777:2004+A1:2009. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(
25、s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Significant changes The significant changes with respect to the previous edition EN 1777:2004+A1:2009 are listed below: a) Scope revised to state more precisely, limitation of scope to HP
26、s with classification group B type 1 according to EN 280:2001, 1.4 only and deletion of requirements and tests relating to all other groups and types not covered by the scope, flat belts for extending structure drive systems excluded from scope; b) terms and definitions of “hydraulic platform (HP)“
27、and “levelling“ added; c) some terms and definitions revised; d) list of significant hazards editorially revised and hazards relating to self propelled HPs and Group A HPs (where the vertical projection of the centre of gravity of the load is always inside the tipping lines) deleted, which are outsi
28、de the scope; e) specific tests directly linked to the appropriate requirement; f) requirements relating to temperature range, forces, calculation, fatigue stress analyses, chassis and stabilizers revised; g) requirements and tests added relating to “Moment sensing system with increased safety requi
29、rements and enhanced overload criteria“ as a new, fourth solution to reduce tilting hazards and hazards caused by exceeding of permissible loads; h) requirements and tests added relating to a minimum residual load of 6 % of the vehicles unladen mass (obtained on the not loaded side, in the most unfa
30、vourable position); i) new subclause 5.13 “Safety devices“ added analogous to EN 280/A1:2004; j) requirement added that the extending structure shall be supported in the transport position in such a way as to avoid harmful vibrations during transport; k) requirement added that failures in wire rope
31、or chain drive systems for extending structure shall be self-revealing; l) maximum tensile grade of the wires in wire rope drive systems for extending structure increased to 2 160 N/mm2; m) leadscrew and rack and pinion drive systems deleted; BS EN 1777:2010EN 1777:2010 (E) 5 n) warning signals shal
32、l consist of a continuous visual warning and an acoustic signal; o) height difference after the static overload test is now depending from the rescue height (for HPs with a rescue height up to 30 m, the height difference shall be less than 100 mm following application of 150 % of the rated load 10 m
33、in after unloading, for HPs with a rescue height greater than 30 m the manufacturer shall state the maximum height difference); p) emergency evacuation means for the platform added (rescue ladder fixed in parallel to the extending structure or alternatives after carrying out a risk assessment); q) r
34、equirements on platform doors and guardrails/handrails revised; r) anchoring points for the allowed number of persons in the cage for personal protective equipment against falling added; s) device added to stop all aggravating movements on sustaining impact; t) requirements and tests relating to ope
35、rator seat, controls and electrical systems revised; u) pneumatic and hydraulic control systems revised that besides the specific requirements the basic standards EN 983 and EN 982 applies; v) requirements and tests revised relating to static tilt angle ; w) at acceptance tests and at periodical exa
36、minations and tests the static overload test has been added; x) instruction handbook added with test report, where appropriate, detailing the static and dynamic tests; y) operating instructions for emergency added; z) marking revised; aa) Annex A and Annex B revised according to the changes in EN 28
37、0; bb) former Annex F (Calculation example Dynamic factor, kerb test) deleted, because the kerb test relates to self propelled HPs, which are outside the scope; cc) content of standard editorially revised. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
38、 following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in t
40、he 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 machines that have been designed and built according to the pr
41、ovisions of this type C standard. As no satisfactory explanation could be found for the dynamic factors used for stability calculations in EN 280 and previous national standards, the results of the tests carried out by CEN/TC 98 “Lifting platforms“ to determine a suitable factor and stability calcul
42、ation method for mobile elevating work platforms (MEWPs) have been adopted. The test method is described in Annex B as a guide for manufacturers wishing to use higher or lower operating speeds and to take advantage of developments in control systems. Similarly, to avoid the unexplained inconsistenci
43、es in wire rope coefficients of utilization and drum and pulley diameters found in other standards for lifting devices, EN 280:2001, Annex C based on DIN 15020-1, together with EN 280:2001, Annex D, have been adopted. BS EN 1777:2010EN 1777:2010 (E) 7 1 Scope This European Standard applies to vehicl
44、e mounted Hydraulic Platforms (HPs) as defined in 3.1, intended for use by fire and rescue services. HPs may participate in fire fighting, rescue or protection of persons, protection of the environment and in a variety of other technical operations. This document identifies the significant hazards (
45、see Clause 4) for all sizes of HPs used by fire and rescue services, on the basis that they are supplied in a complete form, tested and ready for use. It also gives methods for the elimination or reduction of these hazards. This document applies only to HPs classified in group B type 1 according to
46、EN 280:2001, 1.4. NOTE 1 HPs of group B type 1 are those where the vertical projection of the centre of gravity of the load may be outside the tipping lines and for which travelling is only allowed with the HP in its travel condition. Consequently this document does not apply to HPs with the followi
47、ng classification according to EN 280:2001, 1.4: group A type 1; group A type 2; group A type 3; group B type 2; group B type 3. This document is intended to be used in conjunction with EN 1846-2 and EN 1846-3. This document deals with the technical safety requirements to minimise the hazards listed
48、 in Clause 4 which can arise during the commissioning, the operational use, the routine checking and maintenance of hydraulic platforms when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This document deals with all significant hazards,
49、 hazardous situations and events relevant to HPs, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer and taking account of their whole lifecycle (see Clause 4). NOTE 2 The lifecycle includes construction, transport, assembly and installation, commissioning, use (including setting, teaching/pr
