Calculation of Operating TKPH: (Ton-Km-Per-Hour)

This document provides instructions for calculating the operating ton-kilometers per hour (TKPH) of hauling vehicles such as dump trucks and scrapers. It explains that operating TKPH is calculated based on average speed and average tire load, which require collecting information on distance, cycle time, tire loads when empty and loaded. The appropriate tire for the vehicle should have a TKPH rating that is greater than the calculated operating TKPH.
