Milton CAT 312E - Manual (Page 9)

Durability Categories Suitable for Any Situation
Caterpillar offers standard bucket categories for excavators.
Each category is based on intended bucket durability
when used in recommended applications and materials.
Each bucket durability is available as pin-on or can be
used with a quick coupler.
General Duty (GD)
GD buckets are for digging in low-impact, low-abrasion
material such as dirt, loam, and mixed compositions
of dirt and fi ne gravel.
Severe Duty (SD)
SD buckets are for higher abrasion conditions such as
well shot granite and caliche. Red area on bucket image
illustrates additional protection against wear as compared
to a GD bucket.
Specialty Buckets
In addition to standard bucket categories, specialty bucket
styles are available for the 312E, each with a different purpose:
• Ditch Cleaning and Tilt buckets are for cleaning ditches,
slope grading, and other fi nish work.
• Wide Tip buckets are for low impact material
where leaving a smoother floor and minimal
spillage are necessary.
Hydraulic Kits
Caterpillar offers field-installed hydraulic kits that are uniquely
designed to integrate Cat Work Tool attachments with Cat
excavators. Hoses and tubes are pre-made, pre-shaped, and
pre-painted to make installation quick and easy.
Comprehensive Product Support
All Cat Work Tools are backed up by a world-wide network
of well-stocked parts depots and highly experienced service
and support personnel.
