The Link-Belt 350 X4; the only long front excavator in its class

The new Link-Belt 350 X4 Long Front excavator is promising an eight per cent improvement in fuel efficiency.

The Link-Belt Series features innovative EPA Final Tier 4 engines from Isuzu that strikes balance between power, productivity and fuel efficiency. As well, the machine does not require a diesel particulate filter (DPF). LBX Company announced the excavator for the United States and Canada in early February.

This machine is the only factory-built, long-reach excavator available in this size range, according to LBX Company.

The excavator is equipped with three engine modes; Speed Priority (SP mode) to get jobs done quickly; Heavy (H mode) for the best blend of power and fuel savings; or Applied Power (A mode), with 13 different rpm settings for precise control of heavy lifting, fine grading or levelling work.

“The 350 X4 LF base machine delivers up to eight per cent faster cycle times than its predecessor,” said Adam Woods, LBX product manager. “This performance increase is largely due to a new proprietary control valve with a 30 per cent larger hydraulic passage area.”

As well, LBX increased the size of the arm, boom and auxiliary spools to reduce pressure loss and distribute oil more smoothly.

“Two electronically controlled Kawasaki variable-displacement axial-piston pumps and one Kawasaki gear pump assure that hydraulic flow is delivered precisely when and where it is needed,” Woods said. “The end result is more smoothness, maneuverability and precision across all operating modes.”

Woods added the performance enhancements don’t compromise fuel efficiency.

“The 350 X4 LF base machine delivers up to eight per cent improved fuel economy than previous models,” he said. “A thrifty two to three per cent DEF consumption rate, combined with a large DEF tank, means you can work long hours without having to worry about refilling DEF.”

The 350 X4 LF features a new factory-designed and built long front attachment, matched to factory-tuned hydraulics. Structural improvements on the lowers include a 28 per cent thicker travel motor case; 14 per cent more stroke of recoil spring; and a shape change on the frames for easier cleaning.

For increased visibility, the Wide Angle Visual Enhancement System (WAVES) may be added to the machine.

“WAVES is an exclusive, award-winning feature for Link-Belt X4 excavators,” Woods said. “The system is easy to use and includes three closed-circuit, high resolution cameras that provide a seamless 270 degree viewing envelope with no blind spots.”

The ROPS and FOPS-certified cab provides improved operator ergonomics and comfort. A large, automotive-grade high-back seat offers lumbar support and tilts to a 155-degree reclining angle for a relaxed environment during breaks. Arm rests move proportionally with the console, which means the distance and angle between joysticks and operator remains the same, no matter how the seat is adjusted.

As well, an 18-cm LCD colour monitor allows the operator to navigate a full menu of user-friendly controls to take full command of the excavator and attachments. The standard rear-view camera is accessible through the monitor, displaying a panoramic view of the worksite from the rear of the machine, with sight guidelines that can be turned on or off by the operator. Rear and side lights may also be added to the camera system.

Other notable new cab features include: dual halogen cab lights (with optional LED lighting); a cup holder and storage areas for cell phones and other small items; newly designed joysticks with easy-to-hold grips and radio mute buttons; MP3 audio input, Bluetooth connectivity for hands-free communication and a standard control pattern changer.

The link-Belt RemoteCare GPS-enabled telematics system allows 24/7 remote monitoring and security. The system tracks and records routine and major service intervals, as well as machine health. If potential failure conditions arise, flashing diagnostic codes on the monitor quickly alert the operator to potential trouble and an email alert is automatically sent.

The system also provides machine location in real time for better job supervision and remote security monitoring. A six-year subscription is included at no extra charge.
