SUMITOMO LS458HD Track Shoe

The production process for the SUMITOMO LS458HD track shoe involves several precise steps to ensure durability and performance:

Casting with Aluminum Molds: High-cost aluminum molds are used in the casting process to achieve accurate dimensions and consistent quality.

Post-Casting Treatment: After demolding, the track shoes undergo cleaning to remove sand and undergo riser milling and other rough machining processes to refine the shape and surface.

Overall Quenching and Tempering: The rough-machined track shoes undergo overall quenching and tempering. This process involves heating the material to a high temperature and then rapidly cooling it (quenching) to increase hardness. Subsequently, tempering is performed to improve toughness and reduce brittleness.

Surface Heat Treatment: Following overall quenching and tempering, the frequently worn surfaces of the track shoe undergo specific heat treatment again. This surface heat treatment is aimed at enhancing the surface hardness, crucial for withstanding wear and tear in operational conditions.

Finishing and Painting: Once heat treatments are complete, the track shoes undergo finishing processes to achieve the desired final dimensions and surface smoothness. Painting is applied to protect against corrosion and enhance aesthetics.

By meticulously following these production steps, SUMITOMO ensures that the LS458HD track shoes meet high standards of strength, durability, and reliability required in crane operations. Each stage contributes to the track shoes' ability to withstand the rigors of heavy-duty lifting and construction tasks effectively
