Milton CAT 525C - Manual (Page 10)

Reliable, Productive Grapples.
Caterpillar designed and manufactured
grapples use box section construction
for ultimate durability. The tong
curvature reduces the time it takes
to bundle the load, and higher clamp
forces deliver excellent load retention
for secure hauls to the landing.
Bunching Grapples. Bunching grapples
are designed for harvesting mid-to-large
diameter trees, usually felled by a
mechanical feller buncher. Its large tong
opening is designed to gather a large
number of these stems per cycle for
maximum loading. It is heavier than the
sorting grapple, but its large capacity
holds more stems for improved production
in smaller trees and large loads.
Thinning Grapples. Thinning grapples
are designed for harvesting small
diameter trees, usually felled by a
mechanical feller buncher. Its large tong
opening is designed to gather a large
number of these small stems per cycle
for maximum loading. Cat grapples
offer large capacity for maximum
performance and productivity.
Sorting Grapples. Sorting head grapples
are designed primarily for use in skidding
larger, inconsistent diameter timber.
The “scissor” action of the tongs is well
suited for gathering individual logs.
Grapple Snubber. Reduces grapple
swing, hydraulic hose stress and
improves component life.
Flow Divider. The high capacity flow-
divider delivers reliable operation and
maintains consistent tong sequencing.
Hydraulic Winch. The 525C features
an electronically controlled hydraulic
winch for grapple applications, replacing
the mechanical winch. The hydraulic
winch improves application flexibility
by allowing the tractive effort to be
used while winching, and eliminating
the continuously rotating driveshaft.
The high capacity winch has four
function controls: reel-in, reel-out,
brake-on, and free-spool. This winch
is driven and controlled by the main
implement hydraulic system.
Cable Winch. An electro-hydraulic
lever controls the winch hydraulic
control valve, located on the winch case.
The integrated software electronically
protects free-spool clutches.
The C-500 mechanical winch is
available on cable skidders where
higher line speeds and max drum pull
are important. Winch sump oil is used
for hydraulic control and lubrication.
Decking Blade. The decking blade
efficiently clears landings and roads,
and maintains log decks. It features box
section steel arms for superior strength
and durability. Decking blade pusharms
are mounted directly to the mainframe
for excellent strength, and set lower
and forward for efficient clearing of
slash and debris as well as log deck
maintenance. The electro-hydraulic
control improves operator comfort
and control of the decking blade.
• Heat-treated bolt-on edge and
maintenance-free pivot joints for
outstanding durability.
• The 525 C is available with
four blade options to allow it to be
customized to many different types
of operating conditions:
– No Blade – for industrial
applications
– Narrow Decking – 85" width for
general purpose applications.
– Wide Decking – 105.4" width
with bolt-on cutting edges –
for improved coverage of tires
and high decking blade usage.
– Extended Decking – 123.5" width
with bolt-on cutting edges –
for the fullest coverage of tires
and high decking blade usage.
