Technical Description

The Liebherr R914 Compact Litronic is a versatile crawler excavator designed for efficient operation in confined spaces with a compact swing radius of 1.55 meters. Powered by a Deutz TCD3.6L4 turbocharged and after-cooled diesel engine rated at 122 hp (90 kW) compliant with Tier 4 Final emissions standards, it ensures reduced emissions and enhanced fuel efficiency. The engine features a dry-type air cleaner, sensor-controlled idling, and an exhaust gas recirculation system with a diesel oxidation catalyst and SCR system, supported by a 46.3-gallon fuel tank and a 5.3-gallon urea tank for selective catalytic reduction. The excavator offers four boom and stick configurations varying in breakout forces up to 20,008 lbs (ISO) and maximum digging depths up to 19.1 ft, with maximum reach along the ground reaching 29.4 ft. Bucket capacities range between 0.5 to 1.4 cubic yards, allowing adaptability across different digging and loading tasks. The hydraulic system operates at a relief valve pressure of 5,076 psi, facilitating smooth and powerful hydraulic functions through proportional joystick controls for additional hydraulic attachments. Structurally, the R914 Compact Litronic has an operating weight of approximately 36,376 lbs and ground pressure of 6.5 psi, offering excellent stability. The undercarriage features maintenance-free rollers and a drawbar pull of 34,620 lbs, supporting a max travel speed of 4.2 mph. The machine’s cabin is designed for operator comfort with automatic climate control, high-resolution touchscreen controls, and safety features including ROPS. Electrical systems feature 24V voltage, dual 135 Ah batteries, and a 28V/80A alternator. The excavator also incorporates advanced Liebherr technologies such as the axial piston motor swing drive with integrated brake valve and torque control, achieving a swing speed of up to 10 rpm. Overall, the Liebherr R914 Compact Litronic balances compact dimensions, powerful performance, and sophisticated control systems optimized for demanding urban and construction environments.
