1. The Primary Function of Mass Material Haulage Transport a Large Amount of Material: The primary function of mass material haulage is to transport a large amount of material since the majority of the material that is being moved is generated by equipment (loader, excavator, drill). A large truck is capable of hauling several hundred tons of material, making it equivalent to several dozen highway trucks. Connect Two Important Sites: The primary function of mass material haulage is to connect the loading equipment located in the mine layout (e.g. electric rope shovel and hydraulic excavator) and the unloading area (e.g. crusher, stockpile, waste dump, leach pad).
2. Enhance Productivity & Throughput Cycle Time and Cycle Time Efficiency: The design focuses on minimizing the load-haul-dump cycle time. For example, the use of high horsepower engines, heavy-duty suspension systems, and large capacity bodies provide fast speeds for loaded and empty trips on mine haul roads. Cadence for Filling Load: The entire design was engineered around the concept of the load-haul dump cycle. Every component of the truck has been designed to support the maximum legal or engineered weight to maximize the amount of materialloaded on each trip. Uptime and Availability: Mining is a 24 hour a day, 7 days a week operation that requires both continuous operations as well as continuous availability. As such, these trucks are designed to be very durable and dependable and provide a design that allows for maximum operational hours.
3. Operate in Very Harsh Conditions Tough Terrain: Mass material haulage moves over unpaved, uphill, down and uneven, changing haul roads within the mine pit. Harsh Environments: Mass material haulage must be able to withstand dust, mud, extreme temperatures (both arctic and desert) and highaltitudes. Excessive Load Cycle: The constant loading of a truck by large weight/impact (dropping rock), hauling, and dumping is cyclical, therefore the truck experiences excessive load stress and fatigue continuously throughout the life of the truck.
