Underground mine railways - But strap Fl 30 for rail 30E1
Grubenbahnen - Flachlasche Fl 30 für Schiene 30E1
Overview
In particular in underground hard coal mining with its difficult and often changing operating conditions, track conveyance offers various advantages. In addition to the usability in the case of a low load-bearing capacity of the subsoil, the easy expansion and adaptability of the systems is of importance. The flexible design of the rolling stock results in comparatively few restrictions regarding the transportable material to be conveyed. This standard specifies the dimensions and materials of but straps which are used in mining as track connectors in underground mine railway systems. The standard has been prepared by NA 008-05-01 "Grubenbahnen" ("Mine railways") of the Mining Standards Committee (FABERG) at DIN.
