Modern Quarrying Q1 2022

ELIMINATING GUESSWORK IN LOADOUT PROCESSES Given that the precise determination of the weight of products being carried at quarries is a crucial parameter in the daily functions of operations, it is essential to adopt efficient and accurate on-board weighing solutions. With the Trimble Loadrite L3180 SmartScale, the next generation of onboard weighing that uses artificial intelligence for more accurate, precise and faster loading, quarry operators can better optimise loadout, track productivity and prevent overloading.
