HYDRAULIC EXCAVATORSCat Hydraulic Excavators are the most versatile machines on the jobsite,
working in applications ranging from small landscaping projects to large
surface extraction mines—and everywhere in between. Together, Cat
buckets and G.E.T. make up the only bucket system designed and developed
to optimize hydraulic excavator performance and your productivity. Rely on
your Cat dealer for expert support and service for your speciﬁc application.

HYDRAULIC EXCAVATORS 1

SYSTEM OVERVIEW
Hydraulic excavators are extremely versatile machines used for a variety of purposes, from
grading to mass excavation to demolition work. A hydraulic excavator’s main work tool is abucket, but these machines can also be equipped with hydraulic couplers to pick up a variety
of tools.
Balancing your desired productivity/penetration with the wear life of your system is critical.
Excessive wear material can reduce productivity and increase fuel burn. Cat hydraulicexcavator buckets and G.E.T. are designed as a balanced system to increase life while
minimizing drag.

2 HYDRAULIC EXCAVATORSTIP SELECTION GUIDE
Even though bucket tips come in many shapes and sizes, you don’t have to be an
expert to choose the right ones. Use the chart below to determine if the material you’redigging in is high, medium or low impact and abrasion—then ﬁnd the balance you needamong these three factors:

1 STRENGTH
2 PENETRATION
3 WEAR LIFE

The ability to withstand digging andpenetrating shocks and high breakout forces

The ability to penetrate tough material
when it’s tightly compacted, rocky or frozen

The ability to withstand wearing, scouring andabrasive action of the material being handled

CAT ADVANSYS™ TIP & ADAPTER SYSTEMBUILT TO DELIVER MAXIMUM PRODUCTIVITY AND THE LOWEST BUCKETLIFECYCLE COST IN THE TOUGHEST APPLICATIONS.
Cat Advansys is built for machine productivity, balancing tip wear material and penetration
requirements. Integrated hammerless retention ensures you are back to work in minutes
without a separate retainer.

BASE EDGE SYSTEMSFASTEST INSTALLATION TIMES IN THE INDUSTRY.
Cat base edge systems go through a series of carefully controlled manufacturing processes todeliver maximum strength, durability and long life. They come completely welded and assembled,
dramatically shortening your installation and replacement time.

INCREASE
DURABILITY

A consistent heat-treat process maximizes strengthand resists abrasion. Shot blasting removes impurities
that can cause inclusions on a weld, and controlled
cooling reduces the chance of stress points.

SAVE INSTALLATION& REPLACEMENT TIME

Butterbead is applied to the back side of thebase edge and the top strap of the corner
adapter, so you can weld the edge onto thebucket without preheating.

OPTIMIZE MACHINEPERFORMANCE

Base edges are designed by Caterpillar engineers
for optimal performance on speciﬁc machines.

HYDRAULIC EXCAVATORS 21

BASE EDGE SYSTEMS
Base edge replacement involves replacing a base edge assembly, which includes adapters weldedin from the factory, or replacing a bolt-on cutting edge (BOCE) base edge, which comes withfactory-drilled holes for bolt-on G.E.T. Choose from three shapes (base edge for BOCE, straight andspade base edge assemblies) to get the right protection for your application.

The protection you need, with no preheating required—that’s what you get with butterbead weld prep. This
technique, which involves applying a layer of weld to a heat-treated, higher hardness part, makes it possible
to weld a base edge to a bucket without preheating the hardened part. Choose from two shapes (straightand spade) on cutting edges thicker than 50mm and three levels of build to get the right protection foryour application.

We offer four standard bucket durability categories suitable for any application. Each category isbased on the bucket’s intended durability when used in the recommended application and material.

GENERAL DUTY
» For digging in low-impact, lower-abrasion materials such as dirt,
loam and mixed compositions of dirt and ﬁne gravel. Example:
Digging conditions in which General Duty tip life exceeds 800 hours.

HEAVY DUTY
» For a wide range of impact and abrasion conditions including mixed
dirt, clay and rock. Example: Digging conditions where Penetration
Plus tip life ranges from 400 to 800 hours.

» HD buckets are a good “center line” choice, or starting point,
when application conditions are not well known.

HYDRAULIC EXCAVATORS 29

SEVERE DUTY
» For higher abrasion conditions such as well-shot granite andcaliche. Example: Digging conditions where tip life ranges from
200 to 400 hours with Penetration Plus tips.

EXTREME DUTY
» For very high-abrasion conditions including high quartzite granite.
Example: Digging conditions where tip life is less than or equal
to 200 hours with Extra Duty tips.

30 HYDRAULIC EXCAVATORSCHOOSING THE RIGHT DURABILITY.
Choosing the wrong bucket can easily reduce production and increase operating costs by
10-20% or more. It can also cause unnecessary wear and fatigue for both machine and bucket.
Contact your local Cat dealer for more detailed information on choosing the right excavator,
bucket and work tool attachment combinations to meet your application needs.

HYDRAULIC EXCAVATORS 31

ADDITIONAL BUCKET STYLES
Several different bucket styles are available—each with a special purpose:

DITCH CLEANING
These buckets are designed for cleaning ditches, sloping, grading and otherﬁnish work. Their shallow depth and compact size make working in conﬁned
areas easier. Drainage holes allow liquid to empty so material dumps moreeasily. Ditch Cleaning Buckets are available for 311-336 excavators.
Tilt Buckets feature a full 45° of tilt in each direction, powered by two doubleacting cylinders. Tilt Buckets are available for 311-329 excavators.

CENTER-LOCKTM PIN GRABBER PERFORMANCEThis bucket is designed with a patented recessed pin to provide maximum
digging performance while keeping the versatility and convenience of a coupler.
Tip radius is reduced and allows up to 10% improvement in breakout force whencompared to a conventional pin-on bucket and coupler combination.
Center-Lock Pin Grabber Performance Buckets are available for 315-349
excavators in General Purpose and Severe Duty durability.

POWER
Power Buckets are for use in abrasive applications where breakout force andcycle times are critical—and for use in materials such as tightly compacted
mixed dirt and rock. (Not recommended for clay.) Breakout force is maximized
due to decreased tip radius and increased pin spread. Machine cycle times inmost material are improved over a standard bucket in a similar application.
Heavy Duty Power Buckets are available for 320-336 excavators.

WIDE TIP
Wide Tip Buckets are intended to perform best in low-impact materials such as
dirt and loam where leaving a smoother ﬂoor and minimal spillage is necessary.
The bucket is engineered to be used exclusively with Cat Wide Tips. Corner
adapters face straight forward to create a smooth edge.
General Duty Wide Tip Buckets are available in widths from 24” to 78”
for 311-349 excavators.

HIGH CAPACITY
High Capacity Buckets are designed and built for use in high-production truckloading applications. With proper application and set up, these buckets will
move more material in a minimal amount of passes—maximizing production.
High Capacity Buckets are available for 336-390 excavators in General
Duty durability.
