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 ModesThe 318E 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 engine speed low during light loading 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 resale value.
Biodiesel-Ready Fuel SystemYou have added flexibility with the C4.4 ACERT engine because it’s equipped to run on B20 biodiesel fuel that meets ASTM 6751 standards. Just fill it up and go.
Engine You can count on reduced emissions, economical and reliable performance. » Learn More
Hydraulic SystemOne 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 318E is loaded with several unique features that will put more power to the ground with less money out of your pocket.
Pumps and ValvesThe 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 RegenerationElectric 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.
Hydraulics You can move dirt, rock, and debris with speed, precision, and efficiency. » Learn More
ControlsYour operators can adjust the right and left joysticks for individual preferences, helping the operator become more comfortable, more productive, and more alert.
MonitorYour operators can keep safely focused on the job at hand with a high-resolution LCD monitor (1) that is programmable in 44 languages to support today’s diverse workforce. It also projects the image from the rearview camera, further enhancing your job site safety and productivity.
Power Supply and Auxiliary Audio PortTo keep your operators happy, comfortable and connected, two 12-volt power supply sockets are located on the radio near key storage areas for charging electronic devices such as an MP3 player and cell phone. An auxiliary port on the radio allows your operators to plug and play MP3 audio through the cab’s speakers.
StorageYour operators can store their gear in storage spaces located in the front, rear, and side consoles. 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 ControlAn automatic climate control system features five air outlets with filtered ventilation to make your operators comfortable in either hot or cold climates.
SeatsThree seat options help give your operators all the comfort they need for a long day of work. Air suspension, heated, and air-cooled seats are available. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments.
Operator Station Your operators will enjoy the incredibly quiet and comfortable cab. » Learn More
FrameYou can expect excellent quality, reliability, and durability with the 318E’s reinforced lower and upper frames (1). Both are built to handle a hard day’s work over and over again.
UndercarriageLong undercarriage (2) supports any type of work you can do with an 18 metric ton machine. The track rollers are a double solid-pin-type design to improve reliability; an optional two-piece guiding guard helps maintain track alignment and improves the machine’s overall performance.
CounterweightWhether you’re on flat ground hogging dirt or on a slope surgically placing rip rap over drainage pipe, the 3.4 mt (3.8 t) counterweight (3) provides plenty of weight out back to keep you balanced and productive. With integrated links, you can also easily – and safely – remove the counterweight for maintenance or shipping.

Cat Grade Control Depth and SlopeCat Grade Control Depth and Slope is a standalone factory offering that allows your operator to reference a site elevation and input simple elevation and slope targets into the display to give them real-time bucket tip position through the cab monitor. This allows them to cut or fill to the target elevation the first time, which minimizes the need and cost for traditional grade checking. It also enhances job site safety and helps your team complete jobs quicker with fewer cycles, which means you’ll save money on fuel.
For enhanced site features and more complex designs, Cat Grade Control Depth and Slope can be upgraded with Cat AccuGrade™ components like GPS and Universal Total Station (UTS). These positioning technologies interface with site infrastructure to allow your operators to know exactly where the bucket tip is in regards to an engineer’s digital design, which saves your operators benching time and improves their productivity and accuracy.
