THE EFFECT OF REINFORCEMENT PLATES FOR MINING TRUCK MAIN FRAME RAIL CRACKS

Abstract

One of the most widely used haul trucks in Indonesia’s mining industry is the 100 metric ton class mining truck. It is popular for its excellent lifecycle costing and well-known for its sturdy design, reliability, and compatibility with the country’s operating environment. However, recent years have seen reports of issues with recurring main frame rail cracks that have the potential to affect the structural integrity, durability, and overall lifetime of the truck. For this comparative study, the aim is to understand and quantify the effectiveness and durability gains through adding internal stiffener plates into a truck’s main frame. The study focuses on the background data provided by the mining industry to conduct statistical analysis, failure analysis, and simulations through finite element analysis (FEA). Through these testing methodologies the efficiency and performance of the reinforcement plates can be quantified, offering valuable insight into material properties and areas for future improvements.
