Engine
Built for power, reliability, economy and low emissions.
Performance. The Cat C13 engine with ACERT Technology offers 21% greater displacement than the 3176C, and runs at 10% lower speeds for better fuel economy and reduced wear.
Fuel Consumption. ADEM A4 controller uses sensors throughout the engine to manage engine load and performance. The ADEM A4 controller is the muscle behind engine responsiveness, selfdiagnostics, controlling emissions,
and fuel economy.
Low Sound and Vibration Levels.
The engine mounts are rubber-isolating mounts matched with the engine package to provide optimum sound and vibration reduction. Another benefit of ACERT Technology, the C13 engine can shape the rate of fuel injection,
a process that reduces engine noise levels and vibration.
Fuel System. The Cat C13 ACERT engine features electronic controls that govern the mechanically actuated unit fuel injection (MEUI) system. MEUI provides the high-pressure required to help reduce particulate emissions and deliver better fuel economy through finer fuel atomization and more complete combustion.
Cooling System. The 345C L layout separates the cooling system from the engine compartment. The cooling fan is hydraulically driven with a variable speed control that manages fan speed to provide optimized cooling.
Air Cleaner. The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab.
A warning is displayed on the monitor when dust accumulates above a preset level.
Turbocharger. The Cat C13 ACERT engine uses a Wastegate Turbocharger for improved performance.
Cold Weather Starting Kit. The kit consists of four batteries, heavy-duty harness, large capacity starting motor and the ether starting aid. With this kit, the 345C L has the capability to start at -32°C.
Environmentally Responsible Design
Caterpillar machines not only help you build a better world, they help maintain and preserve the fragile environment.
Outstanding performance.
Many features designed to provide outstanding performance which can mean more work done in a day, less fuel consumption and minimal impact on our environment.
Emissions. ACERT Technology is a differentiated technology that reduces emissions at the point of combustion. The technology capitalizes on Caterpillar’s proven leadership in three core engine systems: fuel, air and electronics.
Quiet operation. The hydraulically driven cooling fan is thermostatically controlled, so the fan only runs at the speed necessary to maintain correct system operating temperatures. The result is cool quiet operation with less disturbance to the surrounding environment.
Ozone protection. To help preserve the earth’s ozone layer, the air conditioning unit uses only R-134a refrigerant which does not contain harmful chlorofluorocarbons (CFC’s).
Fewer leaks and spills. Engine oil and encapsulated hydraulic oil filters are positioned vertically and are easy to reach to minimize spillage. Service intervals are extended to reduce the times fluids are changed and handled. The new hydraulic oil fine filtration system attachment extends the service interval from 2000 to 5000 hours. Compatible with Cat HEES hydraulic bio-oil for ecologically sensitive applications. Finally, the new Cat Extended Life Coolant extends service (up to 6000 h) so there is less need for fluid disposal.

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, eliminating 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.
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.

Operator Station
Designed for simple, easy operation and comfort,
the 345C L allows the operator to focus on production.
Cab Design. The workstation is spacious, quiet and comfortable, assuring high productivity during a long work day.
The air conditioner and attachment switches are conveniently located on the right-hand wall, and the key switch and throttle dial are on the right-hand console. The monitor is easy to see and maximizes visibility.
Seat. A new optional air suspension seat is available in the 345C L. The standard and optional seats provide a variety of adjustments to suit the operator’s size and weight including fore/aft, height and weight. Wide adjustable armrests and
a retractable seat belt are also included.
Skylight. An enlarged skylight with sunshade provides excellent visibility and good ventilation.
Hydraulic Activation Control Lever.
For added safety, this lever must be in
the operate position to activate the machine control functions.
Climate Control. Positive filtered ventilation with a pressurized cab comes standard. Fresh air or re-circulated air can be selected with a switch on the left console.
Windows. To maximize visibility, all glass is affixed directly to the cab
eliminating the use of window frames. Choice of fixed or easy-to-open split front windshield meet operator preference and application conditions.
50/50 split front windshield allows both upper and lower portions to be stored in an overhead position.
70/30 split front windshield stores the upper portion above the operator. The lower front windshield features a rounded design to maximize downward visibility and improves wiper coverage.
Both openable versions feature
a one-touch action release system.
The fixed front windshield is available in standard duty laminated glass or high impact resistant laminated glass.
Wipers. Parallelogram wiper, including a washer nozzle is mounted below the cab windshield, optimizes the operator’s viewing area and offers continuous and intermittent modes.
Monitor. The compact, full-color, graphical display monitor, new with the 345C L, displays machine, maintenance, diagnostic and prognostic information, in twenty different languages.
Monitor angle can be adjusted to minimize sun glare.
Cab Exterior. The exterior design uses thick steel tubing along the bottom perimeter of the cab, improving the resistance of fatigue and vibration. This design allows the FOGS to be bolted directly to the cab, at the factory or as an attachment later, enabling
the machine to meet specifications and job site requirements.
Cab Mounts. The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort.
