Undercarriage
Choice of undercarriage to meet your specifi c needs.
Multi Terrain Loader Undercarriage
The Cat 247B Series 3 and 257B Series 3 Multi Terrain
Loaders feature a fully suspended, rugged, durable rubber
track that is lightweight and pliable, yet reinforced with high
tensile strength cords. The undercarriage provides extremely
low ground pressure, allowing these machines to operate
over sensitive surfaces and in soft underfoot conditions.
The independently suspended undercarriage distributes the
load and greatly reduces shock and vibration throughout
the machine for a comfortable ride and excellent bucket
load retention. The undercarriage also features:
• Heavy duty torsion axles that independently suspend
each side of the machine frame for a smoother ride over
rough terrain, even at high speeds.
• Components that are replaceable as individual wear
items, reducing owning and operating costs.
• Low ground pressure: 27.3 kPa (4.0 psi) for the
247B Series 3 and 31 kPa (4.5 psi) for the 257B Series 3.
Compact Track Loader Undercarriage
The Cat 259B Series 3 Compact Track Loader features a
fully suspended, steel embedded rubber track undercarriage
for versatility, durability and comfort. Heavy-duty torsion
axles suspend the undercarriage and can move independently
relative to the machine and each other. These axles absorb
most of the shock to the machine and operator, especially
over rough terrain. This means smooth travel, even at
high speeds, as well as better load retention and greater
productivity. The undercarriage also features:
• Steel embedded rubber track that provides excellent
durability in a wide variety of applications.
• Steel rollers with metal face seals for long-term
durability and reliability in even the toughest conditions.
• Simple recoil grease tensioning system for quick track
tension adjustment.
• Two track options – standard track width of 320 mm
(12.6 in) or optional 400 mm (15.7 in) track.
• Low ground pressure: 41.2 kPa (6.0 psi) with the
standard track and 34.4 kPa (5.0 psi) with optional
400 mm (15.7 in) track.
