What Is That Screen Measuring on a Mining Truck? 😳

What Is That Screen Measuring on a Mining Truck? 😳 This is a PLM system — short for Payload Meter. Instead of using giant scales every time the truck loads up, the system measures pressure changes inside the truck’s suspension system. Here’s how it works: When the truck is empty, nitrogen gas inside the suspension sits at a baseline pressure. As material fills the hopper, the extra weight compresses the suspension and increases that pressure. Sensors detect those changes, and the system calculates how much load the truck is carrying. Why does it matter? Because overloading can damage equipment, reduce efficiency, and create serious safety risks. For giant haul trucks moving hundreds of tons, knowing the weight in real time saves money — and prevents expensive mistakes. Would you trust pressure sensors to measure something this heavy? 👇 #mining #engineering #trucks #technology
