Bucket Specifications
Caterpillar offers a very comprehensive list of high
strength steel buckets. High strength steel allows thinner
components which helps keep the weight down, main-
tains durability and improves loadability. The wrong bucket
can reduce production 30-40% or more. Caterpillar’s
in-depth knowledge of machine design, bucket design
and application experience allows offering
machine
matched
packages that optimize performance.
Additional bucketsmay be available and the listed buckets
may not be available in all sales areas. Contact your Cat
dealer for your specific bucket needs.
