New Nomenclature for Hydraulic Excavator Buckets

Hydraulic Excavators

NEW NOMENCLATURE FOR HYDRAULIC EXCAVATOR BUCKETS

Improved bucket selection Caterpillar continues to recognize the need for a range of buckets for various applications and with varying durability requirements—from site development to granite quarries. The new, global nomenclature is simplified, consistent, and based on the durability of the bucket. These considerations allow a clear and consistent bucket posi- tioning to help facilitate appropriate bucket selection and recommendation — and put Caterpillar in a better position to support machines on a global scale. Dealers and customers in North America will see changes in bucket nomenclature and improvement in bucket designs. What dealers will see with the change Today, North American HEX buckets are grouped into three main categories: General Purpose (GP), Heavy Duty (HD), and Heavy Duty Rock (HDR). New nomen- clature brings in four primary categories, each represent durability. They are: General Duty (GD), Heavy Duty (HD), Severe Duty (SD), and Extreme Duty (XD). Within the Extreme Duty class a new bucket specific for use in granite will be available for the large excavators.

Caterpillar will soon be moving to a new global nomen- clature for buckets on small, medium and large HEX machines and associated linkages. The end result will be a manageable, consistent bucket offering in all regions regardless of where the machine or bucket may be built and shipped. The new bucket designs and nomenclature will be introduced over the next several years, as D and E Series HEX machines are introduced. Why the change? Consistent product line Buckets currently sold into different regions of the world have been designed and manufactured independent of each other resulting in different bucket styles and nomen- clature. As Caterpillar becomes more global, we recognize this can lead to confusion in the marketplace as machines and buckets are sourced from different areas.
