Milton CAT 385C L - Manual (Page 11)

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. Three types of booms and six sticks
are available, offering a range of
configurations suitable for a wide variety
of applications. The 385C L offers a
large combination of reach and digging
forces for optimum versatility.
Boom Construction. All 385C L booms
have large cross-sections and internal
baffle plates to provide higher rigidity
and less stress. All booms are stress
relieved for extended life.
Reach Boom. The 10.0 m (32 ft 10 in)
Reach Boom is for use in deep trenching
applications where long reach and depth
are necessary. Two long sticks are
available for this boom.
General Purpose Boom. The 8.4 m
(27 ft 7 in) GP Boom has been designed
to balance the reach, digging force and
bucket capacity required for a wide
range of applications. Four sticks are
available for use with the GP boom.
Mass Excavation Boom. The 7.25 m
(23 ft 9 in) Mass Excavation Boom
is most suitable for high production
loading where reach and depth are less
important. It allows use of the largest
buckets. Two sticks are available for
this boom.
Stick Construction. The 385C L 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.
All sticks undergo a stress relieving
process for greater durability.
Sticks. There are six sticks for maximum
versatility in reach, digging forces, and
bucket capacity requirements of various
applications. Each stick is designed for
use in combination with a specific
boom and bucket family.
Bucket Linkage. Two bucket linkages are
available for the 385C L. Both linkages
are available with or without a lifting
eye on the power link.
• The HB linkage is used with the
longer sticks and HB family buckets.
• The JB linkage is used with shorter
sticks and JB family buckets.
Power Link. The new 385C L 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 385C L
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.
