OTR Tyre Selection Inputs for Earthmoving Work explains the operating evidence, measurements and asset details needed to evaluate this tyre topic consistently across a fleet or worksite.

Describe the Real Duty

For OTR Tyre Selection Inputs for Earthmoving Work, use one time window so measurements and operating events describe the same duty.

OTR Tyre Selection Inputs for Earthmoving Work 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.

OTR Tyre Selection Inputs for Earthmoving Work — Field Data Sheet

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

Movement

Distance, travel time, stops, waiting and manoeuvring.

Duty boundary

Start, finish, repeat frequency and the operating period represented.

Load

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

Build the Duty Profile

  1. Split the work at meaningful surface and load changes.
  2. Use machine time, distance and event records from the same period.
  3. Mark temporary conditions instead of averaging them silently.

Using the Duty Profile

The practical value of OTR Tyre Selection Inputs for Earthmoving Work is the ability to compare like periods without losing the reason behind an unusual value.
