SITE SEVERITY SURVEY

HAUL ROAD PROFILING AND TRANSPORT CYCLES

To improve a site’s productivity while preserving tyre performance, it is sometimes useful to re-examine the haul road profiles:

• slopes,
• elevation,
• corner radius
• etc.

The improvement in productivity leads to an increase in the extraction rate. In preserving the general safety of the site, this evolution must also take into account the limits imposed by the machines and their tyres.
This is why Michelin’s technicians propose full site audits, in the course of which various vehicle parameters are analysed; for example, accelerations, speeds adopted in bends, braking (frequency, duration, harshness), etc.

This analysis, made with specific software connected to a GPS, serves as a basis for recommending haul road profile improvements, maximum speeds at various points (depending on the machines and/or loads), etc.
