CATERPILLAR 318B LN CRAWLER EXCAVATOR

The Caterpillar 318B LN is a mid-size hydraulic excavator engineered for versatile earthmoving and material handling applications. Powered by a Cat 3046T diesel engine delivering 115 hp (86 kW) flywheel power and 119 hp (89 kW) net power, this machine combines robust performance with efficient fuel consumption from its 74-gallon tank. The excavator features an operating weight of approximately 39,683 to 40,540 lbs, depending on undercarriage configuration, making it suitable for transportation and site mobility. The long narrow (LN) undercarriage provides a 6.6-foot track gauge, enabling permit-free shipping at 8.5-foot widths. The hydraulic system delivers 79.3 gpm at maximum pressure settings of 4,980 psi for implement and travel functions, with 3,700 psi swing pressure for precise directional control. Boom regeneration circuits and cross-sensing technology optimize hydraulic efficiency and cycle times. Four interchangeable boom-and-stick configurations deliver maximum cutting heights ranging from 28.2 feet to 32 feet, digging depths from 18.5 to 23 feet, and reach distances up to 32.1 feet along the ground. The 5-inch bore boom cylinder (47-inch stroke) and 5.1-inch bore stick cylinder (54-inch stroke) provide substantial digging force, while the 4.3-inch bucket cylinder ensures responsive bucket control. Maximum drawbar pull reaches 39,000 lbs, supporting challenging terrain navigation. With a 2.9 mph travel speed and comprehensive sealed track components, the 318B LN delivers durability and productivity across construction, demolition, and quarrying operations.
