The Link-Belt 355 X4S excavator is the flagship model of the X4S Series - built upon the foundation of the X4 Series with added functionality and new features. It’s also the largest minimum swing radius excavator in the Link-Belt product lineup, weighing approximately 78,709 lbs. It delivers a maximum digging depth of 22 ft. 10 in., maximum reach at ground level of 34 ft. 8 in. and a bucket digging force of 39,340 lbf.
The unit is powered by an Isuzu AQ-6HK1X six-cylinder, Tier 4 engine that produces 205 net hp at 1,800 rpm. Four work modes offer varying levels of selectable rpm settings. The new Eco mode maximizes fuel economy and the new Lifting mode ensures power boost is always on during lower rpm crane tasks. A reversible fan is an available option.
The 355 X4S is equipped with a newly designed, full-size cab that offers more operator room and comfort. The additional headroom and legroom pair with the high-back air suspension seat with heat and tilt functions built in to enhance the operator experience. The overall cab layout has been improved by adding on-screen climate controls with better airflow, onboard Bluetooth, dual cup holders and a smartphone storage tray relocating the 12V outlet upfront, a free-swing switch, better spaced and more comfortable footrests, and a straight travel pedal.
The 355 X4S comes standard with two high-resolution cameras, one at the rear and one on the right-hand side of the machine. The optional WAVES camera system adds a third camera and gives the operator a full 270° view around the machine. A new 10-in. LCD monitor gives the operator greater visibility of machine functions and safety features, including the ability to display all three camera images at the same time while still monitoring machine information and notifications. Also through the new monitor, operators can customize joystick button assignments and the monitor buttons to activate frequently used functions and screens instead of relying on the factory defaults alone.
When setting up work tools, individual names can be created and stored in the monitor, making it quicker and more user-friendly to choose the correct settings for the installed tool. Operators can also prioritize and distribute hydraulic flow to arm-in, boom-up, or swing functions, depending on the immediate need of the job, directly through the monitor.
Serviceability remains a strong feature with ground-level access to all regular maintenance items and easy-to-use oil sample valves. A new standard dual-band modem improves RemoteCARE communication and functionality with greater range and real-time data capabilities. RemoteCARE provides 24/7 remote monitoring, machine health and security features.
