About new  bucket design for CATERPILLAR 

The new bucket line for Caterpillar 374D and 390D hydraulic excavators take full advantage of increased digging performance.

In the near future, the new bucket line will also become available for the E-series excavators & other models of excavators like Doosan, Komatsu, Hyundai, Hitachi, liebherr & Volvo.

Current excavator buckets in EAME (Europe, Africa, Middle East) are based on four main categories: Excavation (X), Extreme Excavation (EX), Rock (R),

and Heavy Duty Rock (HDR) buckets. The new nomenclature replaces these categories with General Duty (GD), Heavy Duty (HD), Severe Duty (SD), and Extreme Duty (XD).

"The D-Series excavators are robust, powerful machines. Performance increases over the C-Series bring the machines up a size class. Digging forces are increased due to larger bucket and stick cylinder diameters and a longer idler link. The total of these changes equals significant increases of the bucket forces over the earlier models." The General Duty (GD) buckets are for digging in low impact, lower abrasion materials such as dirt, loam, and mixed compositions of dirt and fine gravel, while the Heavy Duty (HD) is for a wide range of impact and abrasion conditions including mixed dirt, clay and sand and gravel.

Severe Duty (SD) is used in higher abrasion conditions such as shot rock and sandstone, and Extreme Duty (XD) is for very high abrasion conditions including high quartzite granite.
