Abstract
A duty cycle data acquisition system for a truck having an elevatable dump body, a hydraulic hoisting mechanism, throttle and transmission controls, and a retarder further including a microprocessor having an analog imput corresponding to ground speed of the truck and which records the amount of time the ground speed remains in any of a plurality of increments corresponding to the speed range of the truck in one of eight histogram output memories selectively determined by the inputs of a plurality of on-off switches corresponding to throttle position, transmission forward or reverse position, retarder position, and a one-shot timer switch activated by a loaded dump body actuating circuit, the latter circuit including a switch sensing body position relative to the frame disposed in series with a pressure switch located in the hoist mechanism, the pressure switch being calibrated to close only when a loaded body is lifted.
