LINK-BELT 3400 QUANTUM LONG FRONT CRAWLER EXCAVATOR

The Link-Belt 3400 Quantum Long Front excavator is a heavy-duty machine engineered for high-reach and deep-digging applications. It features a turbocharged 6BG1T engine with a displacement of 396 cubic inches (6,489 cc), delivering 153 horsepower at 2,150 rpm and a maximum torque of 388 lb-ft at 1,700 rpm. The hydraulic system includes dual variable displacement axial piston pumps and a gear pump for pilot controls, providing a hydraulic pump flow capacity of 110 gpm and operating at a system relief pressure of 4,980 psi. This enables powerful arm digging force up to 8,820 lbs and bucket digging force of 31,090 lbs in standard mode, increasing in Power Up Mode. The machine has an operating weight of 61,300 lbs and uses a 51-shoe undercarriage per side, with 31.5-inch-wide shoes and a track gauge of 8.5 feet. It achieves ground pressure of 5.9 psi and a maximum travel speed of 3.4 mph, with 9.7 rpm swing speed and a tail swing radius of 9.9 feet. The excavator's maximum cutting height is 45.2 feet, and maximum digging depth reaches 47.6 feet, complemented by a maximum reach along ground of 60 feet and vertical wall digging depth near 40 feet, ideal for extended reach tasks. Dimensions include a shipping height of 10.3 feet, shipping length of 47.6 feet, and a cab height of 9.9 feet. The bucket capacity ranges from 0.8 to 0.9 cubic yards. Fuel capacity is 81.9 gallons, with hydraulic fluid capacity at 58.2 gallons, supporting long operation cycles. The machine runs on a 24-volt electrical system with a 40-amp alternator, optimized for rugged performance in demanding excavation environments.
