Technical Description

The Link-Belt 3400 Quantum is a heavy-duty hydraulic excavator designed for high-performance digging and lifting applications. It features a turbocharged Isuzu A-6BG1T engine delivering 153 hp (114 kW) at 2150 rpm with a maximum torque of 388 lb-ft at 1700 rpm, ensuring robust power for demanding tasks. The excavator’s operating weight stands at approximately 53,190 lbs, combining stability with maneuverability. Hydraulic performance includes dual variable displacement axial piston pumps and a pilot gear pump with a hydraulic pump flow capacity of 110 gpm, supporting a system relief valve pressure of 4980 psi to maximize lifting and digging forces, with bucket digging force reaching up to 33,960 lbs in Power Up Mode. The machine offers three boom/stick option configurations, with maximum digging depths ranging from 20.8 ft to 24.3 ft, max reach along ground extending up to 35.1 ft, and max cutting heights from 30.6 ft to 32.7 ft, providing versatility to suit varied job site demands. The bucket capacity ranges from 0.8 to 1.8 cubic yards, with a reference bucket size of 1.3 cu yd, optimized for efficient material handling. The undercarriage includes 51 shoes per side with 31.5-inch shoe size, 9 track rollers per side, and an 8.5 ft track gauge, enabling a low ground pressure of 5.3 psi for reduced site impact and stable travel with a maximum speed of 3.4 mph. Additional features include a tail swing radius of 9.9 ft, ground clearance of 1.6 ft, and dimensions supporting a shipping height near 10.6 ft and length around 33 ft for transportability. The machine integrates Link-Belt Intelligent Quantum (IQ) Control with selectable working modes, auto-idling, and power-up functions for operational efficiency and ease of use. Electrical systems operate at 24 volts, complemented by a 40-amp alternator and comprehensive cooling and lubrication capacities, underscoring its reliability and durability in heavy construction environments.
