Triple flat mining chains

Master Profile triple flat mining chains are innovative products in which the height  of vertical links has been lowered even further  in comparison to the height of double flat chains. The chains are of special design which allows them  to be a part of the most efficient haulage systems, having significantly greater strength and durability in comparison to round link chains made acc.  to DIN 22252 or flat link chains acc. to DIN 22255  of the same height. Vertical links in triple flat mining chains are as high as round links produced acc. to DIN 22252, which are three sizes smaller in diameter, e.g. triple flat link chain 34×126-75 is of height b₄= max 75 that corresponds to the height of round link chain 24×86, b₂= max 79.
