DIN EN 13232-7:2012-01 EN 13232-7:2006+A1:2011 (E) 6 Introduction The requirements of crossings with moveable parts are that they are capable of performing their intended purpose, which is to allow a vehicle to pass the area where the two rails cross wit
29、h a continuous running edge. That means the wheels of the vehicle are fully supported and guided in the whole crossing area, either in the facing or trailing direction. The main criteria for the selection of crossings with moveable parts are: improvement of ride comfort; reduction of noise and vibra
30、tion; reduction of maintenance; mixed traffic conditions (e.g. train/tram); security against derailment. This last point is particularly important (critical) in diamond crossings. Effectively, as the wheel diameter and the obtuse crossing angle decrease, the distance without guidance (EN 13232-3:200
31、3, 4.2.5) increases. Therefore, to assure the safety of running of the wheel set over the diamond crossing, it is sometimes necessary to design the obtuse crossing as moveable. Rules and recommendations for security against derailment in diamond crossings are set down in part 9 of this standard. The
32、 crossings with moveable parts shall be designed to withstand all external forces from rolling stock, thermal influences etc. The customer shall specify the maximum strains or stresses due to external thermal forces that the crossing with moveable parts has to withstand. Operating, signalling system
33、s, heater systems, load bearing supports, maintainability and safety are all major factors which should be taken into account during the design. The performance criteria shall be based on information given by the customer. The design and selection of types of crossings with moveable parts will be in
34、fluenced by axle loads, frequency of traffic and speed. DIN EN 13232-7:2012-01 EN 13232-7:2006+A1:2011 (E) 7 1 Scope The scope of this part is: to establish a working terminology for crossings with moveable parts, which means crossings with moveable parts to close the gap of the running edge, and th
35、eir constituent parts, and identify the main types; to list the minimum informative requirements for the manufacture of crossings with moveable parts and/or their constituent parts; to formulate codes of practice for inspection and tolerances for crossings with moveable parts and/or their constituen
36、t parts; to establish the limits and extent of supply; to list the method by which crossings with moveable parts and their constructional parts should be identified and traced; to list the different and varying ways by which crossings with moveable parts can be described, using the following paramet
37、ers: geometry of crossings; types of construction; performance requirements; design criteria; tolerances and inspection. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

43、ith moveable parts. These are crossing with moveable point (see Figure 1) and crossing with moveable wing rails (see Figure 2). In both cases: The wings and vee support can be: saddle (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, sy
44、mmetric thick web section etc.). The vee can be: monobloc (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). Rail profiles shall be according to EN 13674-1 and EN 13674-2. In the case of a crossing with
45、 moveable point: point may or may not contain a longitudinal sliding area; vee of point and splice rail may be coupled by bolting, welding or fabricated out of a monobloc and welded to their respective adjacent legs. For example see Figures 3, 4 and 5. In the case of a crossing with moveable wing ra
46、ils a longitudinal sliding area is not required. Other types of construction and their requirements shall be agreed between customer and supplier. 3.2 Obtuse crossings with moveable parts The main type of obtuse crossing with moveable parts is the switch diamond crossing (see Figure 6). The wing and
47、 switches rails support can be: DIN EN 13232-7:2012-01 EN 13232-7:2006+A1:2011 (E) 9 saddle (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). The wing rail can be: monobloc (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). Switch diamond crossings can be used in obtuse crossings with or without single or double slips. Rail profile
