The Link-Belt 350 X3 Tier 4A excavator is a heavy-duty machine optimized for demanding earthmoving tasks, featuring a maximum digging depth of 24 feet and a maximum reach along the ground of 36 feet. It is powered by a turbocharged Isuzu AL-6HK1X diesel engine delivering 266 hp (198 kW) at 1,900 rpm, utilizing an electronically controlled high-pressure common-rail fuel injection system that complies with Interim Tier 4 emissions standards. With a displacement of 7.8 liters and six cylinders, the engine offers improved fuel efficiency—up to 10% better than predecessor models—and robust torque output around 769 lb-ft, enhancing both performance and operational economy. The excavator’s operating weight is approximately 80,028 lbs (36,300 kg), providing excellent stability for heavy lifting and digging deployment. The hydraulic system integrates Kawasaki variable-displacement axial-piston pumps ensuring faster cycle times and increased lift capacity, with a bucket digging force exceeding 55,000 lbf with auto power boost. The machine’s design includes a redesigned ROPS-certified cab for improved operator comfort and safety, along with features like idle start engine protection and an auto engine warm-up that optimizes engine performance and longevity. Its undercarriage features a wide track gauge (31.5 in shoes), providing low ground pressure and superior traction, suitable for varied jobsite conditions. Equipped with a fuel capacity of 153 gallons and advanced filtration systems, the 350 X3 balances endurance with minimal downtime for maintenance. Overall, the Link-Belt 350 X3 combines powerful engine performance, precise hydraulics, and operator-focused design for superior productivity on large-scale excavation jobs.
