Technical Description

The Liebherr R317 is a compact crawler excavator engineered for versatile construction and material handling applications. Powered by a turbocharged BF4M1013EC Deutz engine producing 117 horsepower at 1800 rpm, this machine delivers 87 kilowatts of net power with a displacement of 293 cubic inches. The excavator operates on a 24-volt electrical system with a 55-amp alternator and maintains a fuel capacity of 76.7 gallons for extended operational periods. Weighing approximately 39,022 pounds in operating configuration, the R317 features a robust undercarriage with seven track rollers per side, two carrier rollers per side, and 23.7-inch shoes delivering optimal ground contact and stability. The track gauge measures 6.6 feet wide, while ground clearance stands at 1.6 feet. Maximum travel speed reaches 3.2 miles per hour with a swing mechanism capable of 9 rotations per minute, enabling efficient jobsite repositioning. The hydraulic system incorporates a pump with 78.5 gallons-per-minute flow capacity and operates under 5,076.4 psi relief pressure, supported by a 45-gallon fluid reservoir. The machine accommodates bucket capacities ranging from 0.2 to 1.2 cubic yards, with a standard reference bucket of 0.7 cubic yards. Boom and stick configurations offer multiple reach options, with maximum digging depths between 17.9 and 20.4 feet and maximum reach along ground spanning 28.6 to 31.2 feet depending on configuration selection. The tail swing radius measures 8.1 feet, facilitating operation in confined spaces typical of urban construction environments.
