Amendments In comparison with the December 1974 edition, the following amendments have been made. a) Rail type A 150 is included for the first time. b) Additional dimensional and gwmetrical tolerances have been specified. c) More information has been given with regard to section parameters. d)
13、 The standard has been editorially revised. 1) Issued by the Verein Deutscher Eisenhttenleute (Society of German Ferrous Metallurgists), obtainable from Verlag Stahl- eisen mbH, Postfach 10 51 64, D-40042 Dsseldorf. DIN 536 Part 1 Page 5 Explanatory notes It was originally intended to prepare a new
14、series of standards on crane rails, but after many justified objections were raised at the draft stage, the project was terminated, and the decision was made to update the specifications of the present standard. To ensure interchangeability with crane rails complying with the previous edition, no ch
15、anges were made to the principal dirnen- sions. Over time, crane systems have been modified, and new designs developed, which involve an increase in the load the wheel exerts on the rail and an improvement in the properties of the wheel material. In practice, this has meant that type A 120 rails suf
16、fered frequent fractures, particularly in the welded joints. Laboratory tests and analyses have shown that at the load levels currently involved, the strength of the welded joint zone falls below the fatigue strength at a stated number of cycles, i. e. the possibility of fracture cannot be ruled out
17、. To ensure the future performance of crane rails at these higher load levels, type A 150 rails have been specified here. The con- necting dimensions for their baseplates correspond to those for type A 120 rails, so that no changes need to be made to the rail fixings when this type is incorporated i
18、nto existing rail-wheel systems. However, changes will have to be made to the crane design, since the head of type A 150 rails is 45 mm higher than type A 120, which will have a negative impact on other features (e.g. required power supply). The shape of the head was previously required to be flat,
19、but is now to be slightly curved. Laboratory tests and practical experi- ence have shown that this causes the load to be applied more centrally and prevents an accumulation of stresses at the rail edges. The dimensional and geometrical tolerances and section parameters have been specified in greater
20、 detail and brought into line with the design principles given in DIN 1080 Parts 1 and 2, which reflect the state of the art. Other standards relating to crane rails are currently in preparation, these covering elastic bedding of crane rails, crane rail fixings, and sole plaies.
