Part No. 578-9616 Cat Weld-On Half-Arrow Cutting Edge 

The Cat 578-9616 weldable half-arrow cutting blade is an original official ground engaging component made by Caterpillar. It is strictly produced following the brand's worldwide precise casting techniques and unified quality management rules.

This blade is specially adjusted to fit the structure and tough working conditions of underground LHD loaders. As a versatile combined guard edge, it gets rid of the drawbacks of old wear parts that only serve one purpose. It allows people to redesign and change loader buckets in various ways, and works to shield bucket edges, strengthen overall structures as well as improve machine working performance all at once.

This half-arrow edge stands out with multi-functional customizable adaptability to meet diverse underground construction demands. It can be installed as a side cutter to strengthen side protection and improve penetration against hard rock and compacted ore layers, efficiently handling high-resistance stripping and excavation tasks. Alternatively, it can be applied as an inter-tooth protective segment to fill the fan-shaped gaps between tooth groups, eliminating common field issues such as exposed tooth areas, material scouring, hollowing and uneven wear. Providing full coverage for bucket edges, side areas and blind zones between teeth, it builds a complete dead-angle-free protective system, reduces premature local damage, and significantly extends the overall service life of the bucket.

In terms of structural performance, the product adopts an original factoryintegrated weld-on design that seamlessly fuses with the bucket body for superior overall rigidity, structural strength and impact resistance compared with conventional bolt-on components. Without assembly gaps or loosening risks, it reliably withstands continuous underground heavy impact, high-frequency vibration and repeated material abrasion, maintaining stable performance without deformation or shedding during long-term intensive operation. Equipped with an optimized streamlined half-arrow profile, it effectively reduces digging resistance, improves cutting smoothness and full-bucket loading efficiency, and delivers consistent high productivity even in narrow and restricted underground working environments.
