Caterpillar 318 Excavator

Since its introduction in the 1990s, the 300 Series family of excavators has become the industry standard for production and performance. The Cat 318 and the E series continue that trend-setting standard. Built to meet the U.S. EPA Tier 4 Interim emission standards, the 318E makes an excellent choice for people who need a well-balanced utility machine that delivers power and fuel economy in an easy-to-transport package. The Cat 318E comes equipped with several new features and benefits, including two power modes and a Biodiesel-Ready fuel system. The long undercarriage 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.  Always use quality replacement parts when maintaining your Cat 318 series hydraulic excavator.
