Abstract
The method for facilitating the maintenance of a conveyor structure having a long and heavy duty moving conveyor belt mounted on rollers which are mounted on a base, wherein the belt is driven by a drive motor, said method having the steps of establishing one or more stationary zero set points on the structure, providing one or more cycle points on the belt, each cycle point marking the terminus of a designated travel distance of the belt, providing a counter on the structure for measuring the distance traveled by any of the cycle points on the belt beyond one or more designated set points, providing one or more work stations along and in proximity to the belt, and providing a reset device for resetting the counter to a desired starting value when a designated cycle point arrives at a designated set point, spotting one or more event sites on the belt, transmitting a signal to a computer that an event site has been spotted, the computer being provided with data sufficient to determine the distance which the spotted event site must travel to a forward work station, and operating the computer either to signal an operator to control, or to itself control an aspect of the operation of the conveyor structure for enhancing the maintenance of the belt.
