Booms, Sticks and Linkage

Designed for flexibility, high productivity, and efficiency in a variety of applications.

Front Linkage Attachments. Select the right
combination of front linkage with your Cat
dealer to ensure high productivity from the
very start of your job. Two types of booms
and three sticks are available, offering a range
of configurations suitable for a wide variety
of applications and offer a large combination
of reach and digging forces for optimum
versatility. All booms and sticks undergo a
stress relieving process for greater durability.
Boom Construction. The booms have large
cross-sections and internal baffle plates to
provide long life durability.
Reach Boom. The reach boom (6150 mm)
is designed to balance reach, digging force
bucket capacity, offering a wide range of
applications as digging, loading, trenching and
working with hydraulic tools.
Mass Excavation Boom. The mass boom
(5550 mm) is designed to provide maximum
digging forces, bucket capacity and truck
loading productivity.
Stick Construction. Sticks are made of
high-tensile strength steel using a large
box section design with interior baffle
plates and an additional bottom guard
to protect against damage.
Reach Sticks. Two lengths of reach
sticks are available to suite a variety
of applications. Reach sticks use the
CB2 linkage.
R3.2CB2. The 3200 mm stick gives
the largest working envelope with
medium-sized buckets.
R2.6CB2. The 2650 mm stick uses
larger capacity CB2 family buckets
and is best suited for trenching,
excavation and general construction
applications.
Mass Stick. The mass excavation stick
is available for higher digging forces
and increased bucket capacity.
M2.5DB. The 2500 mm stick provides
excellent digging envelope with large
bucket capacity and high force levels.
Bucket Linkage. Two bucket
linkages (CB2 and DB) are
available, with lifting eye on
the power link.
Power Link. The new power link
improves durability, increases
machine-lifting capability in key
lifting positions, and is easier to
use compared to the previous lift
bar design.
Linkage Pins. All pins used in
front linkages have thick chrome
plating, giving them high wear
and corrosion resistance. The large
diameter pins smoothly distribute
the shear and bending loads to
help ensure long pin, boom and
stick life.
