The size and type of the bucket should be properly selected depending on the density of the material and the expected bucket fill factor. Depending on the Bucket fill factor
conditions, Komatsu buckets may perform more than rated capacity thanks to powerful boom linkage, efficient bucket shape and high rim-pull.

This bucket is used for excavating and loading blasted rock on rock crushing job sites, or for
Excavating bucket excavating natural ground. It has a flat-blade, straight cutting edge, and provides superior rigidity
