Modern mining equipment requires extremely high durability for undercarriage parts. The Excavator track shoes designed with triple groove track shoes have three reinforcing ribs to make the distribution of grounding pressure more uniform. According to test data from a professional excavator top roller factory, this design extends the lifespan of traditional double ribbed track shoes by 25%. When the supporting Excavator bottom roller experiences wear, the Heavy duty Excavator bottom roller replacement standard procedure must be followed, including: 1) measuring the radial runout of the roller (should be ≤ 2mm), 2) checking the integrity of the seal, and 3) adjusting the preload using a hydraulic tensioning device. It is worth noting that the special quenching process of the triple groove structure can achieve a surface hardness of HRC58 or higher. Part of the article's resources are sourced from the internet.
