Steel Track Chain for Sumitomo SH75 Excavator
The Steel Track Chain for Sumitomo SH75 is a heavy duty undercarriage component used on excavator travel systems. It is designed to fit compatible Sumitomo SH75 machines. The track chain supports the machine weight and provides traction on soil, gravel, mud and construction sites. It works with the drive sprocket, idler, rollers and track frame to move the excavator.
Function of a Track Chain
A track chain is an endless loop of links, pins, bushings and shoes. The sprocket drives the chain, and the shoes grip the ground. The chain distributes machine weight over a large area, which reduces ground pressure. This helps the excavator work on soft or uneven surfaces. The track chain also absorbs shock and protects the undercarriage from some impact loads.
Construction and Materials
Track chains are made from high strength steel. Links and pins are heat treated for wear resistance and strength. Bushings reduce friction between pins and links. Shoes are available in different widths and designs for different ground conditions. The chain must be matched to the machine size and sprocket type. Correct hardness and fit help extend service life.
Compatibility and Identification
The Sumitomo SH75 reference identifies the machine model. Users should confirm link pitch, number of links, shoe width and mounting details before installation. A chain for a different model may not fit or may wear quickly. The sprocket condition should also be checked because a worn sprocket can damage a new chain.
Applications
Track chains are used in excavators, mini excavators and other tracked construction machines. They are suitable for digging, trenching, loading, grading and travel on construction sites. Different shoe types may be selected for standard soil, mud, rock or low ground pressure applications.
Installation Notes
Installation should be performed with proper lifting equipment and safety procedures. The machine should be supported securely. The old chain should be removed carefully. The new chain should be routed over the sprocket, idler and rollers. Track tension should be adjusted according to the machine manual. After installation, check for smooth movement and correct alignment.
Maintenance
Track chains require regular inspection. Users should check for wear, loose bolts, damaged shoes and leaking seals. Track tension should be maintained. Uneven wear may indicate misalignment or worn rollers. Lubrication of pins and bushings depends on the chain design. Replacing worn components early helps prevent damage to the sprocket and idler.
Conclusion
The Steel Track Chain for Sumitomo SH75 is a critical undercarriage component for excavator travel. It provides traction, load support and reliable movement on demanding job sites. Correct fit, installation and maintenance help ensure long service life and machine productivity.
