Mining Division

Prisma Tyres Mining Division is there not only to supply tyres but specially to grant a complete technical consulting in order to minimize as much as possible the annual costs and maximize tyres' life with consequent increase of the productivity.

Thanks to the professional experience of our technicians, gained in more than 35 years in the mining field on behalf of the top manufacturers, we are able to provide innovative services and solutions to cut down as much as possible the costs. This factor became lately of very high importance since nowadays the annual cost for tyres in a mine can affect up to 30% of the total costs.

    • The importance of TKPH (to learn more please click here)

      Definition: Ton kilometer per hour (TKPH) is the measurement of the work load of a tyre and is based on the weight and speed that the tyre can handle without overheating and causing it to deteriorate prematurely. A TKPH rating for a tyre is the theoretical maximum workload it can take (average weight on the tyre * average speed of the truck OR more specifically, tons * km/h).

      Example: On one axle, the truck has two tyres. The total load on the axle is 100 tons when the truck is loaded and 50 tons when the truck is empty. The average load on the axle is 75 tons that is 37.5 tons per tyre. If the average speed of the truck is 20km/h, the tyre rating would need to be 37.5*20 or 750 TKPH to avoid being a limiting factor.

      How TKPH affects haulage in Spry: TKPH is calculated per schedule step. If the calculated TKPH is higher than the tyre’s rating, TKPH becomes a limiting factor. This will result in the Adjusted Cycle Time being increased until TKPH is equal to the Tyre Rating.
