Electric Hydraulic Oil fill Pump
The hydraulic oil site gauge provides easy visibility to know
when hydraulic oil needs to be added. An easy accessible
service wand allows hydraulic oil to be pumped through the
hydraulic filtering system and into the tank. This reduces
maintenance time and helps to maintain oil cleanliness
requirements.
Variable Displacement Pump
Cat
® 511 ZTS Track Feller Bunchers and Harvesters contain
a dedicated variable displacement pump for travel circuit and
implement functions, and a dedicated variable displacement
pump for felling attachments. Cat 521/522/532 ZTS Track
Feller Bunchers and Harvesters contain a dedicated 200 cc
variable displacement pump for travel circuit, a 190 cc variable
displacement pump for boom and implement functions, and
a dedicated 55 cc variable displacement pump for felling and
processing attachments. Optional hydraulic configurations
for dangle harvesting heads and intermittent saw heads are
available for all ZTS models.
Caterpillar ® Hydraulic Oil
Provides maximum protection against mechanical and corrosive
wear in all hydraulic systems. It’s high zinc content reduces
wear, and extends pump life. Provided certain requirements are
met (e.g. S-O-S SM analysis every 500 hours), the hydraulic oil
change interval is extended from 2,000 hours to 4,000 hours.
Biodegradable Hydraulic Oil
The optional biodegradable hydraulic oil (HEES) is formulated
to provide excellent high-pressure and high-temperature
characteristics and is fully compatible with the all hydraulic
components. HEES is fully decomposed by soil or water
microorganisms, providing a more environmentally-sound
alternative to mineral-based oils.
ToughGuard Hoses ™
Abrasion resistant hoses along the boom and stick provide
strength and flexibility, increasing hydraulic hose service life.
The ToughGuard cover consists of a thin layer of UHMW
polyethylene bonded to the rubber cover, providing exceptional
abrasion resistance. In many applications, it eliminates the need
for external guarding.
Hydraulic Packages
Powerful hydraulic system combined with a powerful boom and
stick maximize productivity in any felling or harvesting job.
