Benefits & Features

If your work space is restricted, the 314E CR makes an ideal choice because it can get up close to new residential construction, buildings, fences, hillsides, or any other “crowded” environment with ease. When rotated 90 degrees and working over the side, the 314E CR’s counterweight extends only a bit beyond the track width and doesn’t exceed the length of the track at all. This significantly reduces the risk of your operator damaging the machine and surrounding structures in full swing, which makes for a safer work environment and lower owning and operating costs for your business.

The Cat C4.4 ACERT engine is built to meet your demanding needs all day every day. There is no interruption to your job process as our new regeneration system works automatically with no operator intervention required.

Power Modes

The 314E features two power modes: High power mode is when you need maximum production; economy mode is when you need to balance performance with fuel economy. Two additional fuel-saving features are on demand engine power and engine idle shutdown. On demand engine power keeps speed low during light loading and idling and automatically adjusts speed up when it senses a heavier load; engine idle shutdown automatically shuts the engine off when it’s been idling for more than a specified amount of time that you set, which can save you significant amounts of fuel, reduce your emissions, and even reduce your accumulated service hours, which will extend service intervals and improve re-sale value.

Biodiesel-Ready Fuel System

The C4.4 ACERT engine runs on ultra-low-sulfur diesel fuel, and you have added flexibility of running on B20 biodiesel fuel that meets ASTM 6751 standards. Just fill it up and go.
You can count on reduced emissions, economical and reliable performance.

Hydraulic System

One of the biggest contributors to your productivity and fuel savings is a well-designed hydraulic system, and this is where Cat excavators stand apart. The 314E CR is loaded with several unique features that will put more power to the ground with less money out of your pocket.

Pumps and Valves

The main control valve is built to work with any tool, allowing you to take on multiple tasks with one machine. The main pumps are located side by side and are driven directly by the engine for the highest level of efficiency to reduce your fuel costs.

Boom Regeneration

Electric boom regeneration results in less pressure loss, higher controllability, more productivity, and lower operating costs for you; it works by reusing the flow of oil that travels from the head of the boom cylinder to the rod end of the boom cylinder during your operator’s everyday “boom down” operation. During boom regeneration, engine speed is controlled to be low in order to save extra oil flow from going to the boom cylinders, which saves energy.
You can move dirt, rock, and debris with speed, precision, and efficiency.

Mechanical and air suspension seat options with heated and air-cooled availability give operators all the comfort they need for a long day of work. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments.


Your operators can adjust the right and left joysticks for individual preferences, helping the operator become more comfortable, more productive, and more alert.

Power Supply and Auxiliary Audio Port

To keep your operators happy, comfortable and connected, one 12-volt power supply is located on the radio near key storage areas for charging electronic devices such as an MP3 player and cell phone. An auxiliary port allows your operators to plug and play MP3 audio through the cab’s speakers.


Your operators have storage spaces located in the rear. A dedicated space near the auxiliary power supply will hold an MP3 player and cell phone. The drink holder accommodates large mugs with handles, and a shelf behind the seat stores large lunch or toolboxes.

Automatic Climate Control

An automatic climate control system features seven air outlets with filtered ventilation to make your operators comfortable in either hot or cold climates.


Your operators can keep safely focused on the job at hand with a high-resolution LCD monitor that is programmable in 44 languages to support today’s diverse workforce. It also projects the image from an available rearview camera, further increasing the safety and productivity of your job site.

Your uptime and service intervals are increased with durable and reliable booms, sticks, and linkage pins. Each boom and stick is built with internal baffle plates for additional strength, and each undergoes ultrasound inspection to ensure you get the durability and reliability you expect for any tough application.


Two types of booms are available to meet the variety of tasks you take on in a given day. A reach boom offers you excellent all-around versatility and a large working envelope; a power offset boom allows your operator to stay in the same position to load and dump, which increases productivity when your team is working in narrow, restricted space. A unique bucket-to-cab avoidance feature is also included to ensure safe operation.


Sticks are matched to the booms. The R3.0 m (9'10") stick is best for when you need deep trenching, longer reach, and top truck loading capabilities. The R2.5 m (8'2") stick provides greater breakout force and increases productivity when you primarily plan on using hydro-mechanical work tools. The R2.1 m (6'11") stick combines with the power offset boom to deliver excellent breakout force and cycle speed in those tough-to-reach places. Your Cat dealer can help you pick the best configuration for your business.
