LINK-BELT EXCAVATORS 350 X4LF CRAWLER EXCAVATOR

Technical Description

The Link-Belt 350 X4LF is a mid-sized hydraulic excavator engineered for demanding construction applications requiring extended reach and digging capability. Powered by an Isuzu AQ-6HK1X Tier 4 Final diesel engine producing 268 net horsepower (200 kW), the machine delivers robust performance without requiring a diesel particulate filter, reducing maintenance costs and complexity. With an operating weight of 87,634 pounds, this excavator provides substantial stability and breakout force while maintaining maneuverability on jobsites. The "LF" long-front configuration distinguishes this model, offering a maximum digging depth of 46.3 feet and an exceptional ground-level reach of 60.1 feet, making it ideal for dredging, sloping, and cleaning operations that demand extended working envelope capabilities. The proprietary hydraulic system features a control valve with 30 percent larger passage areas and electronically controlled Kawasaki variable-displacement pumps that deliver cycle times approximately 8 percent faster than predecessors while improving fuel efficiency. Operators can select from three power modes—Speed Priority for rapid work, Heavy mode for optimal power-to-fuel balance, and Applied Power mode with 13 RPM settings for precision tasks. The cab incorporates rollover and falling-object protection, an automotive-grade high-back seat reclining to 155 degrees, and ergonomic armrests that maintain consistent joystick positioning. The 350 X4LF represents Link-Belt's commitment to combining power, efficiency, and operator comfort in a factory-built long-reach excavator specifically designed for professional contractors requiring superior performance in specialized applications.
