Building an OTR Tyre Selection File for Surface Mining explains the operating evidence, measurements and asset details needed to evaluate this tyre topic consistently across a fleet or worksite.

Describe the Real Duty

Begin Building an OTR Tyre Selection File for Surface Mining by defining the exact asset, wheel position and operating period represented by the observations.

Building an OTR Tyre Selection File for Surface Mining becomes useful when the route or work cycle is broken into measurable segments. Distance, surface, stops, gradients, loading state, manoeuvres and unusual events should represent a normal operating period rather than a single convenient trip.

Building an OTR Tyre Selection File for Surface Mining — Field Data Sheet

Use one time base and one asset identity throughout the survey. Separate recurring duty from temporary construction, weather or production changes.

Load

Loaded, empty and partial cycles with the source of the value.

Events

Impacts, cuts, wheelspin, delays or route changes tied to location.

Surface

Road or ground segments, condition, gradients and turning areas.

Build the Duty Profile

  1. Summarise the dominant and most severe recurring segments.
  2. Choose a representative shift, route or production cycle.
  3. Split the work at meaningful surface and load changes.

Using the Duty Profile

Read the completed Building an OTR Tyre Selection File for Surface Mining sheet from the asset outward: confirm identity first, then position, duty and the observed change.
