VOLVO EC220D LR CRAWLER EXCAVATOR

Technical Description

The Volvo EC220D LR excavator is a robust, high-performance crawler excavator engineered for extensive digging tasks, boasting a maximum digging depth of 39.7 ft and a maximum digging reach of 51.5 ft. It is powered by a 172 hp (128 kW) Volvo D6H six-cylinder, turbocharged diesel engine, featuring advanced electronic controls, high-pressure fuel injectors, and an air-to-air intercooler to optimize power output while maintaining low fuel consumption and emissions compliant with Tier 4 Interim standards. The engine incorporates a unique ECO mode that enhances fuel efficiency by up to 5% without compromising performance. The machine’s operating weight is approximately 52,610 lbs, supporting heavy-duty operation and excellent stability. Its hydraulic system is electro-hydraulically controlled with intelligent pump flow management and incorporates a main control valve for on-demand hydraulic flow, reducing losses and enhancing responsiveness and cycle times. The swing system is powered by an axial piston motor paired with a planetary gearbox, providing a maximum slew speed of 12.1 rpm and high torque for precise movement. The undercarriage features two-speed automatic travel motors, multi-disc spring-applied hydraulic track brakes, and well-protected planetary gears for outstanding durability. Operator comfort is ensured by an ergonomically designed, sound-suppressed ROPS-certified cab with intuitive joystick controls, reducing fatigue during long hours of operation. Additional features include a 3-stage air filter with pre-cleaner, automatic idling system for fuel saving, and comprehensive safety systems such as boom and arm hose rupture valves. This combination of power, efficiency, and operator-centric design makes the EC220D LR suitable for demanding construction and excavation applications.
