The climate and mining conditions of Yakutia (temperature fluctuations, vibrations, shock loads) cause accelerated wear of quarry equipment. A study on bulldozers identified the most vulnerable components: ripper tips/shanks and the crawler system. Laboratory analysis of tips from various manufacturers revealed a direct correlation between wear resistance and both hardness and low-temperature impact toughness. Forged tips demonstrated the best results. Practical solutions include developing special material requirements for the Arctic and implementing hardfacing technology. This has allowed Almazy Anabara to significantly reduce annual tip consumption and improve operational efficiency.
