Suspended Undercarriage Design.
Suspended undercarriage design absorbs
impact loads to reduce the shock loads
transferred to the undercarriage by up
to 50 percent in uneven terrain.
Bogie Suspension. Bogie suspension
conforms closely to the ground providing
up to 15 percent more ground contact,
especially in hard, uneven terrain.
Higher traction means less slippage,
better balance, and a smoother ride.
Integrated Carrier Roller Mount.
The carrier roller mount is cast into
the track roller frame making it easier
to add the optional carrier roller in the
field, if conditions require it.
Rollers and Idlers. Feature symmetric
Duo-Cone seals for long sealing life to
prevent oil loss and dirt entry. Toric rings
maintain performance over a wide range
of temperatures. Rollers and idlers are
serviceable and rebuildable to provide
value. Abutment-style caps securely
attach rollers and idlers to the bogies.
Roller Frames. Roller frames are tubular
to resist bending and twisting, with
added reinforcement where operating
loads are highest.
• Roller frames attach to tractor by a
pivot shaft and pinned equalizer bar.
• Large pivot shaft bushings operate
in an oil reservoir.
• A low friction, no maintenance
bushing is used in the saddle
connection.
• Aligned to use more of the available
wear material, running the track to
the outside of the rollers in forward
and to the inside in reverse.
Sprocket Segments. Made exclusively
of Caterpillar Tough Steel™ for longer
wear life and precision machined after
heat treat for proper fit. Segments can
be removed or replaced without
breaking the track.
Positive Pin Retention (PPR) Sealed
and Lubricated Track. Designed for
high-impact and high load applications.
The PPR exclusive Caterpillar design
locks the link to the pin.
Track Shoes. Track shoes come in a
variety of sizes and styles to best match
the working conditions.
