Overview

Powerful Efficiency Delivers Peak Performance

Advanced hydraulic system ensures peak performance with the Cat® 318 D2 L. A new quiet, comfortable cab ensures operators are on their best game through long days on the job site. Easy serviceability and legendary durability complete the package to make this model an all-round industry leader.

Benefits

Powerful Hydraulics

The hydraulic design of the 318D2 L leads to less friction loss, reduced pressure drops, and more power to the ground.

Economy Mode

Balance the demands of performance and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.

Unmatched Durability

Using advanced engineering and software, we carefully analyze each structure to create durable, reliable machines for tough applications.

Features At A Glance

A powerful C4.4 electrically controlled engine meets U.S. EPA Tier 3, EU Stage IIIA equivalent and China Nonroad Stage III emission standards.
Two-pump hydraulic system pressure delivers terrific digging performance and productivity.
Hydraulic cross-sensing system uses two hydraulic pumps under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.

Economy mode maintains breakout forces and lift capacity at standard power, balancing demands of performance and fuel economy.
Boom and stick regeneration circuits save energy during boom-down and stick-in operation.
New compact design utilizes shorter tubes and lines to reduce friction and pressure drops, resulting in more efficient use of power.

The service door on the right side of the upper structure allows ground-level access to the pump, pilot filter, drain filter, and the engine oil filter.
Easily accessible, ground-level service locations allow quick and efficient maintenance.
The left service door allows easy access to the engine radiator, oil cooler, air-to-air-aftercooler, primary filter with water separator (if the two are integrated) and secondary fuel filter.
The radiator air filter features a double-element construction for superior cleaning efficiency; a warning is displayed on the monitor screen inside the cab when the filter plugs.

An adjustable seat and joystick console are designed to meet individual preferences.
Low-effort pilot-operated joystick controls are designed to match natural wrist and arm position for maximum comfort and minimum fatigue.
The full-color LCD monitor is programmable in 42 languages.
The cab shell is attached to frame with viscous rubber mounts to dampen vibrations and sound levels, enhancing operator comfort.

Site prep and finishing work are quick and easy with a Cat® grapple, thumb, and hammer.
Utility work is fast and flawless with a Cat bucket and compactor.
A coupler lets you swap between attachments in seconds without leaving the cab.

The modified X‐frame structure provides a long service life.
Robot-welded and stress-relieved heavy duty boom and stick are standard.
Track shoes, links, rollers, idlers, and final drives are built with high‑tensile-strength steel.
Greased track link between pins and bushings increases undercarriage life and reduces noise.

Anti-skid plating covering the entire upper structure and storage box prevents slipping during maintenance.
Countersunk bolts reduce trip hazards during service and maintenance.
The engine radiator fan is enclosed by fine wire mesh, reducing risk of an accident.
