CATERPILLAR 320F L CRAWLER EXCAVATOR

Technical Description

The Caterpillar 320F L is a medium-class hydraulic excavator engineered for versatile earthmoving and construction applications. Powered by a C4.4 ACERT engine producing 161 net horsepower, this machine delivers up to 8.5% better fuel efficiency compared to its predecessor model. The excavator operates at a maximum travel speed of 3.5 mph with a drawbar pull rating of 46,086 lbs, providing adequate mobility and traction across varied job sites. With a maximum digging depth of 22.1 feet and extended reach of 32.3 feet along the ground, the 320F L accommodates diverse excavation depths and reach requirements. The hydraulic system features a negative flow control design that optimizes pump efficiency by decreasing flow when oil pressure increases, reducing energy waste. Main system hydraulics deliver 113 gallons per minute at maximum flow, with swing pressure capabilities reaching 3,626 psi and travel pressure at 5,076 psi, enabling powerful bucket breakout force and smooth boom control. The machine's operating weight of 49,200 lbs provides stability without excessive ground pressure, suitable for confined spaces and sensitive surfaces. The swing mechanism operates at 11.2 rpm with 45,581 foot-pounds of torque, enabling efficient positioning and material handling. Fuel capacity reaches 108 gallons, supporting extended operation cycles, while the hydraulic system holds 68.7 gallons total, ensuring reliable performance in demanding applications. Equipped with a comfortable ROPS cab and proven structural design, the 320F L combines operational efficiency with operator comfort.
