Cat underground loader buckets deliver unmatched productivity and structural reliability to help lower your cost-per-ton. Our bucket design is also improved with the use of two types of cast corners to help strengthen the side plate to bucket lip joint as well as allowing for various cutting edges. Buckets are available in a range of sizes to suit material types and densities, with multiple options including dump buckets, light material buckets, ejector buckets and the new bolt-together buckets.
