Link-Belt has introduced a pair of new purpose-built machines for material handling and demolition applications.
The Link-Belt 250 X4 material handler and 250 X4 scrap loader/handler feature a two-piece, factory-designed attachment with hose burst check valves.
Both versions also feature an electronically-controlled 177 hp Isuzu engine that meets Tier 4 Final requirements, without the need for a diesel particulate filter.
The material handler configuration has a curved boom and straight arm, while the scrap loader/handler has a straight boom and droop-nose arm.
The hydraulics package features award-winning Spool Stroke Control (SSC) technology to achieve maximum control and productivity.
On the 250 X4 scrap handler, a pre-set hydraulic motor and pump for 15kW hydraulically driven generator with controller installation mount is standard.
“The new hydraulics package delivers up to 7 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. But we didn’t stop there. We increased the size of the arm, boom and auxiliary spools to reduce pressure loss and distribute oil more smoothly.”
Precise hydraulic flow
As well, two electrically-controlled Kawasaki pumps and one Kawasaki gear pump assure hydraulic flow is delivered precisely when and where it’s needed.
“The end result is more smoothness, maneuverability and precision across all operating modes,” Woods said. “All of these performance enhancements don’t compromise fuel efficiency, either.
“A 3 per cent DEF consumption rate, combined with a large DEF tank gives it the longest DEF refill interval in the industry.”
The Link-Belt X4 cab
The X4 cab is designed to improve operator comfort and convenience, featuring a standard air suspension seat with a 5-degree tilt.
As well, the arm rests move proportionally with the console, allowing the distance and angle between joysticks and operator to remain the same, no matter how the seat is adjusted.
The hydraulic cab riser features a higher operator view of 4.85 metres at eye level height. A new in-line drift valve and shock-less cab riser design improve operator comfort and control.
A large, 18 cm LCD colour monitor allows the operator to easily 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.
An under-cab camera option provides all-around visibility and safety.
For maximum visibility, the Wide Angle Visual Enhancement System (WAVES) may be added.
“WAVES is an exclusive, award-winning feature for Link-Belt X4 material handlers and scrap loaders,” 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.”
Other notable cab features include dual LED cab lights; a cup holder and storage areas for small items; newly designed joysticks with easy-to-hold grip and radio mute buttons; MP3 audio input, Bluetooth-enabled for hands-free communication.
The RemoteCARE GPS telematics system provides 24/7 remote monitoring and security.
The system enables operators to track daily fuel economy and machine performance with ease. It also allows users to be more proactive if potential failure conditions arise; flashing diagnostic codes on the monitor to quickly alert the operator of potential trouble. As well, an e-mail alert is automatically sent.
The system also provides machine location in real time for better job supervision and remote security monitoring. A lifetime subscription is included with the X4 models.
Both machines feature a high-wide undercarriage, oversized turn table and larger drive motors for dependable, long-life service.
The bearing tub extends down through the top plate of the X-Pattern carbody and is welded to the bottom and top plates of the carbody for strength and durability. Furthermore, 60 cm 3-bar steel grousers, carbody belly pan, double track guard and sealed link chain are standard.
For servicing, the Link-Belt machines feature ground-level access to all routine service points, including sample ports for engine and hydraulic oil.
All service ports are also easily accessed via hand-turn knobs.
