22、condition in both the running mode and working mode when moving along the track at its maximum speed. These tests shall be deemed to be successful if on representative track: a) the suspension is not detrimentally excited by a representative range of track conditions; b) the machine is able to safel
23、y run through switches and crossings; c) the machine is able to run over raised check rails (as detailed in 5.3); d) the machine does not derail whilst going through switches, crossings and curves. NOTE These tests should be carried out by an authorised body or by the manufacturer of the machine if
24、the manufacturer is recognised as a testing body by the accreditation body. 5.6.5 Lifeguards Machines shall be equipped with lifeguards as described in EN 15746-2:2010, 5.10.2. 5.7 Stability and prevention of overturning Requirements for prevention of overturning and stability are shown in EN 15746-
25、2:2010, 5.11. 5.8 Machine frame and structure 5.8.1 Design of the machine frame 5.8.1.1 Requirements for Category 9 machines Except as shown below there are no special requirements for the frame strength of the machine with respect to its use on the railway. Where a machine is converted from a road
26、vehicle for use on the railway the engineering of that conversion shall not compromise the structural strength of the host vehicle. Any application of Category 9 machines different from the original design of the host vehicle shall require a proof that the machine frame structure complies with the i
27、ntended use. 5.8.1.2 Requirements for Category 8 machines Category 8 machines, machine frame shall be able to withstand the following forces without any permanent deformation when running in a train: a) machines not permitted to be loose shunted or hump shunted shall be constructed to meet the requi
28、rements of the load cases 4.1 to 4.5 of Category FII of EN 12663:2000 with the following deviations: Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/08/2010 08:54, Uncontrolled Copy, (c) BSIBS EN 15746-1:2010EN 15746-1:2010 (E) 27 1) Item 4.5, c) vertical load during lifting of the machine
29、 frame with the bogie to 2 g; 2) Table 12 of EN 12663:2000 to read acceleration in the x direction 3 g; 3) machines which are restricted to be positioned only at the front or rear of a train are permitted to be constructed to withstand towing and impact forces of 0,8 MN. All other Category 8 machine
30、s shall be constructed to meet the requirements of the load cases 4.1 to 4.5 of Category FI of EN 12663:2000 with the following deviations: b) Item 4.5, c) Vertical load during lifting of the machine frame with the bogie to 2 g; and c) Table 12 of EN 12663:2000 to read acceleration in the x directio
31、n 3 g. 5.8.2 Lifting and jacking points Lifting and jacking points shall be fitted capable of safely supporting the whole machine whilst being lifted or jacked. It shall also be possible to lift or jack one end of the machine (including its running gear) with the other end resting on the remaining r
32、unning gear. The locations (and any restrictions of use) of lifting and jacking points, where fitted, shall be detailed in the technical information, see 7, b), 3), viii). For the machines of Category 8 the following requirements apply. The load cases specified EN 12663:2000, 4.3.2 shall apply for l
33、ifting and jacking under workshop and servicing operations. For lifting cases associated only with rescue following derailment or other abnormal incident, where some permanent deformation of the structure is acceptable, it is permissible to reduce the safety factor in Tables 9 and 10 from 1,1 to 1,0
34、. If a factor of 1,0 is used for a validation test, the measured strains shall be extrapolated to demonstrate the conformance to the higher factor. The location of the lifting and jacking points shall be defined by the customers operational requirements. 5.9 Inter machine couplings 5.9.1 General The
35、 detailed design of coupling systems on machines and their associated trailers shall be capable of withstanding, without permanent deformation, loads that will be encountered in service. Any limitations on machine movement, arising from the use of the coupling system, shall be identified and listed
36、on the type approval documentation. Machines that are intended to be coupled together in normal operation shall have coupling systems which are mechanically compatible and compliant with the following: the coupling system shall be designed to transmit, safely and without suffering damage, all the fo
37、rces that arise between machines during their normal operation, including those due to traction, buffing, curving, braking, working, coupling and uncoupling; the coupling system, with the exception of buffers (if fitted), shall engage positively with the coupling system of any rail machine/vehicle (
38、including trailers) to which it is intended to couple in a train or special train as detailed in prEN 15954-1:2009, Annex A; coupling and uncoupling shall be possible on the range of track features defined for the particular machines; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 26/08/2010

40、s the operation of the coupling/uncoupling shall be protected from reasonably foreseeable interference that could result in the systems inadvertent operation; it shall be possible to determine that the coupling systems are positively engaged. It shall be permissible to achieve this directly or by an
41、other suitable system of indication. If the coupling system carries the connections that provide the continuous element of the automatic braking system, these shall be in accordance with EN 14601. 5.9.2 Category 8 machines buffing and drawgear 5.9.2.1 Couplings Requirements shall be according to EN
42、14033-1:2008, 10.1. 5.9.2.2 Buffers Requirements shall be according to EN 14033-1:2008, 10.2. 5.9.2.3 Space to be kept free at the end of the machine Requirements shall be according to EN 14033-1:2008, 10.4. 5.10 Running gear 5.10.1 General 5.10.1.1 Category 8 machines Category 8 machines shall meet
43、 the requirements of EN 14033-1:2008, 7.5. 5.10.1.2 Category 9 machines The running gear structures shall be designed to ensure that no significant permanent deformation or fatigue fracture occurs under all intended load cases. The supplier shall either: a) verify that the stress levels in each comp
44、onent of the running gear and their connection to the host vehicle are acceptable and that due account has been taken of the dynamic stresses produced by running and working on the rails; or b) provide evidence of the stress levels in the running gear and their connection to the host vehicle demonst
45、rating that, via the safety record of machines having a comparable design and loading, that the stress levels in the running gear are acceptable. 5.10.2 Distribution of the wheelset forces in running configuration The weight of the machine in running configuration, including attachments intended to be used, should be as evenly distributed among the wheelsets of the rail wheels as possible.
