Centering on abrasion and impact dimensions, the chart clearly classifies different operation material scenarios. Ranging from top soil and coal with low abrasion and impact to broken slag and high quartzite granite with high abrasion and impact, it recommends materials like GD, HD, SD, XD and configurations of sidecutters and sidebar protectors. It provides precise references for material selection and component adaptation of engineering equipment buckets, expected to enhance bucket durability and operation efficiency.
