oa Civil Engineer in South Africa - Chrome manganese rails

 

Abstract

The decision to upgrade the Broodsnyersplaas - Richards Bay coal line resulted in the important development of a new rail for the SA Transport Services. To accommodate the high axle loads on this line the Cr Mn rail with its high strength and good wearing qualities was considered the most suitable choice. The general requirements and specific problems associated with the manufacture of Cr Mn rails are dealt with, as well as the extent to which problems were overcome by the manufacturer.


The events leading up to the decision to develop the Cr Mn rail are discussed, and design considerations and required in-track applications are also covered. Some early indication of the performance of the rails under existing service conditions is given and future use of Cr Mn rails is discussed.

Die besluit om die spoorbaanstandaard van die Broodsnyersplaas - Richardsbaai Steenkoollyn te verhoog het die ontwikkeling van 'n nuwe spoorstaaf vir die Suid-Afrikaanse Vervoerdienste tot gevolg gehad. Ten eide die hoë asbelastings op hierdie lyn te kon akkommodeer is die Kroom Mangaan spoortaaf met sy hoë sterkte en voordelige slytaslewerende eienskappe as die mees geskikte keuse beskou.


Die algemene vereisters en spesifieke probleme wat die vervaardiging van hierdie tipe spoorstawe ondervind word, word behandel.
Die gebeurtenisse wat die besluit om die ontwikkeling van die Kroom Mangaan spoorstaaf voorafgegaan het, word genoem terwyl daar ook na die ontwerpvereistes gekyk word.
Daar word ook kortliks verwys na die werkverrigting van hierdie tipe spoorstawe onder bestaande verkeerstoestande en na die moontlike groter gebruik van Kroom Mangaan spoorstawe op die Suid-Afrikaanse Vervoerdienste.
