Milton CAT 525C - Manual (Page 7)

Box-Section Construction. Caterpillar
designed and manufactured box section
structures set the industry standard for
reliable, durable main frames. Extensive
computer analysis and field-testing
resulted in the design of the 525C.
Absorbs Twisting and Shock Loads.
Frames can absorb twisting and impact
forces to provide a sound foundation
and well-balanced system for the entire
structure.
Superior Balance. Low center of mass
and weight forward design create
excellent skidder balance.
Maneuverability. The 525C skidder
provides the tightest turning radius for
superior maneuverability while still
maintaining the excellent balance
required for high capacity skidding.
Caterpillar Manufacturing. The front
and rear frames are robotically welded
and manufactured by Caterpillar to
ensure the highest level of quality
and durability.
Hitch. A heavy-duty center section
features oversized plates and bosses to
disperse forces. A large double-tapered
roller bearing is used on the lower
hitch for reduced flexing stress and
maintaining tight joints.
Hitch Pins. The wide hitch pin spread
significantly reduces horizontal loading
on hitch pins and bearings for greater
durability and extended pin and bearing
life. The extra room also increases
hydraulic hose clearance and makes
hose routing easier.
Fenders. Rear frame fender options are
available for both grapple and cable
arrangements.
Arches and Booms. All Caterpillar
arches use box-section construction,
and are thoroughly tested to exceed
durability requirements.
Single Function Arch. This high strength
design is simple to operate and is ideally
suited for logging conditions where
maneuverability is not limited by ground
conditions. This arch is best suited for
use with the bunching head grapple.
Dual-Function Arch. The 525C is
available with a dual function arch and
compatible with a sorting or bunching
head. The dual-function arch offers
variable reach, which minimizes machine
maneuvering to pinpoint a load with the
grapple, and large grapple capacities.
Cable Arch. Allows outstanding line
skidding performance with a two-position
adjustable height fairlead to match site
conditions.
