Innovative practices of composite materials in the field of excavator track shoes

In response to carbon neutrality requirements, XX company has developed a carbon fiber reinforced nylon based triple groove track shoe that reduces weight by 55% compared to traditional steel products. Its unique 3D printed honeycomb structure achieves a compressive strength of 450MPa and has been successfully applied to 20 ton electric excavators. This technology needs to be optimized in conjunction with the rubber coating process of the excavator top roller factory to reduce operating noise by 15%. Laboratory data shows that this composite material excavator track shoes exhibit excellent corrosion resistance in salt spray testing, with only a 0.2mm thickness loss after 3000 hours of testing, but the cost is still 3.2 times that of ordinary steel.
