Technical Description
The Caterpillar 318C LN is a versatile hydraulic excavator optimized for heavy-duty applications, featuring a Cat 3066T 4.0L turbocharged engine delivering 130 hp (97 kW) gross and 125 hp (93 kW) net power. It has an operating weight of approximately 42,660 lbs and offers three boom/stick configurations to adapt to diverse worksite demands. Option 1 provides a maximum cutting height of 29.3 ft, digging depth of 19.5 ft, and loading height of 20.3 ft; Option 2 increases these to 30.4 ft, 20.9 ft, and 21.2 ft respectively; Option 3 offers the greatest reach with a max cutting height of 31.7 ft, digging depth of 22.6 ft, and 22.6 ft loading height.
The excavator’s bucket capacity ranges from 0.6 to 1.4 cubic yards, with a reference capacity of 1 cubic yard, supporting a variety of digging and material handling tasks. The undercarriage features 19.7-inch wide shoes, 8.2 ft track width, and provides a ground clearance of 1.6 ft and drawbar pull of 45,500 lbs, enabling solid traction and maneuverability with a maximum travel speed of 3.3 mph. The hydraulic system delivers a flow capacity of 50.2 gpm at 4,980 psi relief pressure, supporting smooth operation of boom, stick, and attachments, enhanced by a boom and stick regeneration circuit that improves cycle times and reduces fuel consumption.
The excavator’s structural components utilize high-tensile steel for durability, with a box-section boom design and wear-resistant bucket edges. The swing mechanism operates at 10.8 rpm with fluid capacity of 2.2 gallons and a tail swing radius of 8.4 ft, allowing efficient rotation in confined spaces. Key fluid capacities include 84.6 gallons fuel, 67.4 gallons hydraulic fluid, and 8 gallons engine oil, enabling extended operation without frequent servicing. Overall, the Cat 318C LN balances power, reach, and durability for diverse construction and excavation projects.
