The Link-Belt 160 X4 from LBX Company is a 17.4-tonne excavator with an electronically-controlled 112-hp Tier 4 Final Isuzu engine that provides up to 12 percent improved fuel efficiency over previous models. Engine design allows particulate matter to be burned at cylinder combustion, eliminating the need for a diesel particulate filter.

Other new features include a 30 percent larger control valve that creates a larger hydraulic passage area, larger spools and advanced controls to maximize hydraulic system control and responsiveness. Two electrically-controlled Kawasaki variable displacement axial-piston pumps and one Kawasaki gear pump assure that hydraulic flow is delivered precisely when and where it’s needed. The result is more maneuverability and precision across all operating modes, smoother machine operation and up to 12 percent faster cycle times.

The ROPS- and FOPS-certified cab features a large high-back seat with excellent lumbar support. Arm rests move proportionally with the console. With a seven-inch LED colour monitor to interface with the machine, the operator can easily navigate controls for the excavator and attachments.

The standard rear-view camera displays a panoramic view of the worksite from the rear of the machine with sight guidelines added for increased safety. The Wide Angle Visual Enhancement System (WAVES) can be added to provide a full 270-degree viewing envelope with no blind spots. Other notable new cab features include: dual halogen cab lights (with optional LED lighting), newly designed joysticks with easy-to-hold grip and radio mute buttons, and standard control pattern changer.

The 160 X4 features improved boss shaping on boom and arm pins to reduce stress, cast boom tips for improved reliability, and stronger cylinder mounts on booms and arms. Structural improvements on the lowers include a thicker travel motor case, thicker plating between side frame and travel motor case, larger track rollers, increased tread diameter on track rollers, longer front idler hub, and a shape change on side frames for easy cleaning.
