DIN 22255 Flat Link Mining Chain

TOPONE® produces Flat link chains for use in continuous conveyors in mining Complies with DIN22255 dimensions and mechanical properties. Flat link mining chains may replace currently used round link chains of the same diameter, without the need of changing other assembly components.Especially suitable for Armored Face Conveyors, Beam Stage Loaders, road headers.

DIN 22255 Flat Link Mining Chain
Introduction

DIN 22255 flat link mining chains can replace the currently used DIN 22252 round link chains of the same diameter without changing other assembly parts. Compared with round link chains, flat link mining has a larger contact area, which reduces the risk of friction martensite and thus increases service life.In addition, since the outer height of the flat link mining chain (DIN22255) is smaller than the outer height of the round link mining chain (DIN22252), the flat link mining chain can be used as a diameter reduced by one order of magnitude. For example: Flat link chain 42x137 is of the height c2 = max 115 which corresponds to round link chain 38x137 b2 = max 121.
