Crane- & Depot track Crane runways MX-bottom casting Page: 141-09 ThyssenKrupp MX Precision casting materials Our decades of experience have shown that the bottom casting of steel rail support on concrete and its processing quality is crucial to the longevity of the crane runway. It plays a role especially at a discontinuous storage, because by the continuous stress, by edge pressure, the material is stressed. Why to use a bottom casting at all? Due to constant stress to operational and environmental influences, the steel rail support must be grouted to the entire surface. Is not the case that voids are present and movement is possible? This leads to a progressive destruction of the lower casting. The result is a cost associated with downtime and restoration. To avoid this, ThyssenKrupp MX precession casting materials are avaiable for complete surface grouting. Concrete is not recommended as a cast - the structure is not suitable and cause additional voids by shrinking. For no more cross sectional steel profiles, we recommend the elastic MX PUR 880-6.
