Abstract

A communication system between a base station and a plurality of pieces of construction equipment, the communication system including a transmitter and receiver for transmitting measured operational information from the plurality of pieces of construction equipment to the base station. Each equipment piece includes an operational component that is susceptible to damage. A computer based controller is utilized for measuring a plurality of operational parameters of a respective equipment piece and communicating derived measured operational information. A calculator is used for calculating an amount of damage incurred by the component based on the communicated measured operational information concerning the respective equipment piece.
