<strong>Tyre</strong>-<strong>protection</strong> <strong>chains</strong><br />
The anticipated service life of the tyre <strong>protection</strong> <strong>chains</strong> is affected by the rock conditions (hardness, particle size, sharp<br />
edges). The actual service life is greatly influenced by the overall operating conditions, type of operation and also by the<br />
chain maintenance. The chart below gives the approximate service lifespan on different types of rock.<br />
Kind of Rock<br />
Eruptive Rocks<br />
granite, quartz, andesite<br />
basalt, diabase<br />
Metamorphosic Rocks<br />
marble<br />
quartz-rock<br />
