Power to move more dirt, rock, and debris with speed and precision


Hydraulic Horsepower
Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more than just the engine power under the hood - it’s a core strength that differentiates Cat machines from other brands.

Main Control Valve and Auxiliary Valves
The 349E uses a high-pressure system to tackle the toughest of work in short order. The 349E uses a redesigned side-by-side main control valve, which allows for auxiliary hydraulic lines and valve configurations to be simplified for greater reliability.

Return Filter
The return filter is a capsule-type design with a cartridge inside. Unlike many competitors’ offerings, the Cat cartridge features a handle to help remove and change oil without spillage or contamination. A sensor attached to the filter warns the operator if it is full or exceeds a certain pressure level.

Swing Priority Circuit
The swing priority circuit on the 349E uses a new electric valve that’s operated by the machine’s improved Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more finely tuned control, which is critical during material loading.

Electric Boom Regeneration Valve
A new electric boom regeneration valve minimizes pump flow when the boom lowers down, which improves fuel economy. It is optimized for any dial speed setting being used by the operator, which in turn aids controllability and enhances component durability.

Stick Regeneration Circuit
The 349E regenerates the flow of oil from the rod end of the stick cylinder to the head end of the stick cylinder during low-load, stick-in operation - an approach that saves energy and expense.

Operator Station
Comfort and convenience to keep people productive

Operator Station

A new seat range includes mechanical, air suspension, heated, and air cooled options. Each option includes a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.

The right and left joystick consoles (1) can be adjusted to meet individual preferences, improving operator comfort and productivity during the course of a day. With the touch of the button, one-touch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level. The optional heavy lift mode increases machine system pressure to improve lift - a nice benefit in certain situations. Heavy lift mode also reduces engine speed and pump flow in order to improve controllability.

The 349E is equipped with a new LCD (Liquid Crystal Display) monitor (2) that’s 40% bigger than the previous model’s with higher resolution for better visibility. In addition to an improved keypad and added functionality, it’s programmable to provide information in a choice of 42 languages to support today’s diverse workforce. A new “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save significant amounts of fuel. In addition, the monitor serves as a display for the optional rearview camera. Up to two different camera images can be displayed on the screen.

MP3-Ready Radio and Power Supply
The standard radio is equipped with a new auxiliary audio port for MP3 players. Two 12-volt power supply sockets are located near key storage areas for charging.

Storage spaces are located in the front, rear, and side consoles. New space near the auxiliary power supply holds MP3 players and cell phones. The drink holder accommodates large mugs with handles, and a new shelf behind the seat stores large lunch or toolboxes.

Automatic Climate Control
The climate control system features five air outlets with positive filtered ventilation, which makes working in the heat and cold much more pleasant.

Reduced emissions, economical and reliable performance


Cat C13 ACERT Engine
The Cat C13 ACERT Tier 4 Interim engine is built to meet your demanding needs all day long. There is no interruption to your job process because the Cat regeneration system works automatically with no operator intervention required. If your operators are working in heat-restricted areas, they can use a manual override button (1) to move the machine before the regeneration process begins.

Power Modes
The 349E features three power modes to help manage fuel consumption: High power, standard power, and economy. Two additional fuel-saving features are automatic engine speed control and engine idle shutdown. Automatic engine speed control adjusts to the load, keeping speed low during light loading and idling and adjusting up for heavier loads. Engine idle shutdown automatically turns the engine off when idling for more than a specified amount of time that you set, which can save significant amounts of fuel and reduce emissions.

Biodiesel-Ready Fuel System
The 349E runs on ultra-low-sulfur diesel fuel, but you have added flexibility with the C13 ACERT engine because it’s equipped to run on biodiesel fuel up to B20. Just fill it up and go.

Structures and Undercarriage
Built to work in rugged environments

Structures and Undercarriage

The upper frame includes new reinforced mountings to support a new Roll-Over Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.

Fixed and variable gauge long undercarriage systems are available to support various work applications. Heavy-duty track rollers, precision-forged carrier rollers, press-fit pin master joints, and enhanced track shoe bolts improve durability and reduce the risk of machine downtime and the need and cost to replace components. A new segmented three-piece guiding guard is now offered to maintain track alignment and improve performance in multiple applications. A redesigned motor housing prevents mud packing and debris buildup around seals.

The standard 9.0 mt (9.9 t) counterweight maintains large lifting capacity and excellent stability. A counterweight with removal device is available as an attachment to reduce the time required in preparation for transport. Both counterweights bolt directly to the main frame for added rigidity and feature an integrated housing for the new rearview camera option.

Front Linkage
Made for high stress and long service life

Front Linkage

Booms and Sticks
The 349E is offered with a range of booms and sticks. Each is built with internal baffle plates and stress-relieved for added durability, and each undergoes ultrasound inspection to ensure quality and reliability. Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability. Also, the boom nose pin retention method is a captured flag design for enhanced durability.

Two boom types are offered: HD = Heavy Duty Reach. HD is designed for general excavator applications such as multipurpose digging and loading, and it includes additional steel to make it more durable and better suited for more demanding applications like moving rock or using a hammer. ME = Mass Excavation. ME is best used for quarry, high-volume loading, and other demanding applications. The ME front provides higher digging forces due to the geometry of the boom and stick relationship. Bucket linkage and cylinders are also built for greater durability.

Work Tools
You can dig, hammer, rip, and cut with confidence.

Work Tools

Couplers: Quick Tool Changes
Imagine the productivity you’ll achieve with a quick coupler. Combine a robust coupler with a common work tool inventory that can be shared between same size machines and you’ll get performance and flexibility on every job. The Cat Center-Lock™ pin grabber coupler features a patented locking system and highly visible lock. You can clearly see when the coupler is engaged or disengaged from the attachment.

Work Tools: Cut, Crush, Pulverize and Load
No matter your specialty, Caterpillar provides tools that are perfectly matched to get the most out of your Cat machine - quickly and efficiently. Auxiliary hydraulic circuits are available to integrate any Cat work tool with your 349E.

Buckets: Dig, Move, Load
Cat buckets are designed to fill efficiently so you notice a fast, smooth cycle, which means high productivity each time you dig. Wear characteristics of general-duty, heavy-duty, and severe-duty buckets give you solid performance in a wide variety of material abrasions. Ditch cleaning and other specialty buckets are available when needed.

Integrated Technologies
Solutions that make work easier and more efficient

Integrated Technologies

Cat Grade Control Depth and Slope
This optional system (1) combines traditional machine control and guidance with standard factory-installed and calibrated components, making the system ready to go to work the moment it leaves the factory. The system utilizes internal front linkage sensors - well protected from the harsh working environment - to give operators real-time bucket tip position information, which minimizes the need and cost for traditional grade checking and improves job site safety. It also helps the operator complete jobs in fewer cycles, which means less fuel use. Cat dealers can upgrade the system to full three-dimensional control by adding proven Cat AccuGrade™ positioning technologies, including GPS and Universal Total Station (UTS).

Cat Product Link*
This deeply integrated machine monitoring system is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web application called VisionLink™, which uses powerful tools to communicate to users and dealers. *Product Link licensing not available in all areas. Please consult your Cat dealer for availability.

Fast, easy and safe access built in


Service Doors
Wider service doors (1) feature sturdier hinges and latches and a new screen design to help prevent debris entry; a new two-piece hood provides easier access to the engine and cooling compartments.

The radiator, pump, and air cleaner compartments provide easy access to major components. The fresh air filter (2) is located on the side of the cab to make it easier to reach and replace as needed.

Other Service Improvements
The water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level; the electric priming pump is mounted on the primary filter base and is easier to service than traditional hand-priming pumps. The fuel tank features a remote drain cock located in the pump compartment to make it easy to remove water and sediment during maintenance. The engine oil check gauge is situated in front of the engine compartment and is easy to remove. The engine oil filter is situated in the pump compartment for easy access. Changing engine oil is simple due to a unique drain cock designed to prevent spills. The optional Fast Fill Hydraulic Oil System and Fast Fill Engine Oil System make what typically takes hours achievable in minutes.

Features to help protect people


Reinforced Frame
The upper frame is reinforced to accommodate the installation of a new ROPS cab with redesigned overhead guarding to protect operators.

Sound Proofing
Improved sealing and cab roof lining lower noise levels significantly during machine operation.

Anti-Skid Plates
The surface of the upper structure and the top of the storage box area are covered with removable anti-skid plates to help prevent service personnel and operators from slipping during maintenance.

Steps, Hand and Guard Rails
Steps (1) on the track frame and storage box along with extended hand and guard rails to the upper deck enable operators to more securely work on the machine.

High Intensity Discharge (HID) Lights
Cab lights can be upgraded to HID for greater night time visibility.

Visibility - Windows
Increased glass coverage improves visibility while meeting the latest ROPS regulations. The 70/30 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling. The lower window is removable and can be stored on the left wall of the cab shell. An available one-piece front windshield comes with a glass-breaking safety hammer. The newly designed skylight is larger than the previous series’ and provides greater overhead visibility, excellent natural lighting, and good ventilation. The skylight can be opened completely to become an emergency exit.

Monitor Warning System
The monitor is equipped with a buzzer that can warn an operator of critical events like “Engine Oil Pressure Decrease,” “Coolant Temperature High,” or “Hydraulic Oil Temperature High,” allowing for immediate action to take place.

Rearview Camera
A rearview camera (2) housed in the counterweight area is available as an attachment. The image projects through the cab monitor to give the operator a clear picture of what’s behind the machine.
