Operator Station

Roomy and quiet with ergonomic control placement has excellent sightlines to the work area to help keep operator fatigue low and production up throughout the entire shift. Optional climate control maintains constant temperature in the cab in both hot and cold weather.

Multipro Electronic Control System

An user friendly new monitor that shows a wide variety of useful information for machine operation and provides high efficient service data and diagnostic capabilities while maximizing fuel efficiency and performance.


The open-center, two-pump hydraulic system features pump flow control which improves fuel efficiency, ensures smooth controllability, reduces sound levels and extends component life, through an increased maximum flow. The unique tool control option offers the ability to optimize the machine performances according to 5 tool specifications, and to set priorities between tools and implements for maximized efficiency.


The 318C is powered by the Cat 3066 T engine which complies with worldwide emissions requirements. This engine includes several design features which enhance performance, efficiency and reliability. Engine service intervals are increased to 500 hours.

Service and Maintenance

Longer service intervals and easier maintenance results in better machine availability and lower owning and operating costs. Electronic diagnostics means increased productivity.

Undercarriage and Structure

Rugged Caterpillar undercarriage design and proven structural manufacturing techniques assure outstanding durability in the toughest applications, resulting in stability, durability and low maintenance. Standard grease-lubricated tracks extend the undercarriage life.
