Hydraulics
Cat hydraulics deliver power and precise control to keep material moving.
Pilot System. The hydraulic pilot
system controls the front linkage,
swing and travel operations.
Component Layout. The 345C L
hydraulic system and component
locations have has been designed
to provide a high level of overall
system efficiency.
Hydraulic Cross-Sensing System.
The two main hydraulic pumps
use 100 percent of available
horsepower resulting in faster
implement speeds and increased
productivity.
Boom and Stick Regeneration Circuit.
Saves energy during boom-down and
stick-in operation, providing shorter cycle
times and lower operating costs.
Boom and Swing Priority. The hydraulic
system on the 345C L provides automatic
priority function for boom-up and swing
operations eliminating the need for work
mode buttons. When the boom or swing
lever is activated, the system automatically
assigns priority based on operator demand.
Heavy Lift Feature. The operator can select
the heavy lift mode at the push of a button
to boost lifting capability and provide
improved controllability of heavy loads.
Biodegradable Hydraulic Oil.
Biodegradable hydraulic oil is available
as an option.
Auxiliary Hydraulic Valve.
The auxiliary valve is standard. It is used
with optional control arrangements to
operate tools such as hammers and shears.
shears, grapples, hammers, pulverizers,
multi-processors and vibratory plate
compactors.
Hydraulic Cylinder Snubbers.
Snubbers are located at the rod-end of the
boom cylinders and both ends of the stick
cylinders to cushion shocks while reducing
sound levels and extending component life.
Applications and Systems Match
The 345C L is designed for matched performance with Cat Articulated Trucks.
Wide range of front end attachments.
Providing choices for systems
matching to a range of Cat
articulated trucks from the 730
to the 740. This adds flexibility
for a wide range of job conditions
in a variety of applications such as
construction, mining or quarry.
Additionally, systems match
offers versatility in job set-up
whether top loading or same level
truck loading.
Optimum pass match design.
Five to six passes under two minutes,
matched to the Cat 735, gives you
maximum systems production at
the lowest cost per ton of material
moved.
Maximum availability.
New standards for durability and
reliability help ensure that your
loading system has more uptime,
operates efficiently and provides
lasting value and high resale. Tool Control System. The various settings
allows you to optimize the excavator to the job
layout. Five hydraulic pump flow and pressure
setting can be preset, on the monitor, eliminat-
ing the need to adjust the hydraulics each time
a tool is changed. The unique Cat proportional
sliding switches provides modulation to the
tool and the precision work easy.
Quarry Package. The new Quarry
Package attachment consists of a bucket
cylinder guard and reinforcement bars
on the stick, for extra protection in the
most severe conditions.
