Caution should be exercised before using this rescue coupler in the UK, since it is incompatible with many of the potential rescue vehicles. Many UK-based locom

Additionally, locomotives fitted with the Swing-Head Automatic Coupler (which is compatible with buff loads) have very limited space around the drawhook.

This European Standard shall be given the status of a national standard, either by publicati
22、on of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essenti
23、al requirements of Directive 96/48/EC1), as amended by Directive 2004/50/EC2). For relationship with the EU Directive, see informative Annex ZA, which is an integral part of this document. The requirements on coupling interfaces of end couplers will be dealt with in a new work item. According to the

35、le with: the Scharfenberg system type 10 automatic coupler4) having the dimensions specified in Annex A and the draw hook having the dimensions shown in Figure C.1. The main dimensions and characteristics of the rescue coupler shall be as given in Annex B. The mass of the complete rescue coupler in
36、its operational condition shall not exceed 50 kg. The rescue coupler shall be able to withstand the following loads without permanent deformation: maximum tensile load = 300 kN; maximum compressive load = 250 kN. NOTE There are no fatigue requirements for the rescue coupler. The rescue coupler shall
37、 be equipped with handles or components which serve as such for transport and lifting. Material certificates and weld-classes used shall meet current requirements. Welded parts shall be in accordance with prEN 15085 and EN ISO 5817. 4.2 Rescue vehicle characteristics The rescue vehicle characteristi
38、cs to be taken into account are defined as follows: connections for electric cables and air pipes on head stocks of locomotives (see Figure C.3); draw hook (see Figure C.1). Due to different markings located on both sides of the hook it is compulsory to consider a 2 0 59+ mm hook width; pneumatic co
39、upling for brake pipe and main air reservoir pipe (see Annex D).

41、T+00:00 2007, Uncontrolled Copy, (c) BSI EN 15020:2006 (E) 6 4.3 Fitting procedure The rescue coupler shall be placed close to the front of the rescue vehicle. The rescue coupler shall be mounted on the draw hook. It shall be possible for the coupler to be lifted and mounted onto the draw hook of th
42、e rescue vehicle by no more than two persons. The available space around the draw hook of the rescue vehicle shall be taken into account. Mounting of the rescue coupler on the draw hook shall not require any special tools. The coupler shall be secured to the draw hook with a fixing device in such a
43、way that it cannot freely move or come off the draw hook during the rescue operation. Once the rescue coupler is mounted on the draw hook of the rescue vehicle: the installed rescue coupler shall have at least 6 vertical movement from the horizontal during operation; it shall be possible for the cou
44、pler to be adjusted vertically on the draw hook without the need for special tools; coupling and uncoupling operation shall not require any human presence between the rescue vehicle and the failed train unit or train set whilst either is being moved; the rescue coupler and the pneumatic hoses shall
45、not limit the maximum lateral movement of the draw hook. 4.4 Coupling conditions 4.4.1 Mechanical coupling The mechanical coupling between the automatic coupler on the failed train set and the rescue coupler on the rescue vehicle shall be automatic. It shall be possible to couple a train set to a re
46、scue vehicle in a 150 m radius curve. For vehicles fitted with automatic couplers, the car builder shall demonstrate: automatic coupling with a rescue coupler uncoupling performance in 150 m radius curve conditions. The rescue coupler shall be designed to ensure that coupling is possible when the he
47、ight mismatch between the centre lines of the automatic coupler and the draw hook is up to 75 mm. Use of guide horn is not compulsory if this requirement is fulfilled by the vertical adjustability of the rescue coupler. Coupling operation should be done as follows: at a speed not exceeding 2 km/h; t
48、he rescue coupler shall be aligned in order to be coupled with the mating automatic coupler of the failed train unit or train set to be rescued.

Therefore, the rescue coupler air pipe ends shall be equipped with air pipe coupling heads which allow manual connection of the rescue vehicle air pipes (see Figure 1). Following testing on location at the manufacturers establishment the air pipes conne
