All Link-Belt LX series excavators come with Inte-LX, an intelligent computer command control system that monitors hydraulic output and pressures, while regulating engine performance. Inte-LX also maintains engine rpms when load demands change. The electronic governor responds quickly to changes in operating loads, so fuel use is regulated accurately and quickly. By reducing system pressure loss, regenerating return oil and providing double pump flow during key operations, fuel consumption and cycle times are more efficient in 90° swing/dump operations vs. conventional models.
Thomas Equipment Ltd.
Designed for the global market, all Thomas mini-excavators meet EU Stage 2 and Tier II regulations to ensure maximum emission control, while maintaining fuel efficiency. Increased speed of the boom, bucket and arm combined with greater breakout force all add up to increased efficiencies and quicker work cycles. Low noise levels along with suspension seats, a larger operator area, redesigned controls and enhanced safety systems provide for a safe, comfortable operator environment.
Takeuchi excavators utilize a four pump hydraulic system (two variable-displacement piston pumps and two gear pumps). The two main piston pumps share the same rotating group directly coupled to the flywheel, which gives them the ability to operate at peak hydraulic output levels while utilizing less flywheel horsepower and fuel. (The TB108 does not use a four pump hydraulic system.) Several models also offer a standard decelerator feature that allows the operator to return the machine to low idle at the push of a button.
Gradall Industries, Inc.
Gradall excavators are equipped with high-pressure, load-sensing hydraulics that deliver the appropriate horsepower for the job at hand, automatically maximizing both productivity and fuel efficiency. With telescoping, tilting booms, the units are ideally engineered for everything from mass excavation, pavement removal and demolition to fine grading, sloping and ditching. Models are available with highway speed wheeled undercarriages, on/off pavement wheeled undercarriages and crawlers.
IHI/Compact Excavator Sales LLC
The IHI mini-excavator engines and hydraulic systems are designed to deliver the maximum breakout force with the least amount of horsepower and rpms required. The two-gear/two-piston pump hydraulic system is at the forefront of technology for mini-excavators. The piston pumps decrease fuel usage, which boosts the fuel economy by 10% compared to previous all-gear pump hydraulic systems. All IHI equipment exceeds OSHA and Tier II engine rules and regulation standards.
The entire Vermeer excavator product line uses Tier II Kubota Diesel engines, which add power and performance without sacrificing fuel economy. For example, the CX219Z uses a hydraulic piston pump system that feeds the pilot-operated controls to enhance cycle times and reduce overall time on the job. In addition, the load-sensing hydraulic system eliminates unnecessary oil flow to the hydraulic circuit. This allows the machine to direct oil flow where and when it is needed, thus minimizing horsepower and rpm requirements to power the system.
John Deere Construction & Forestry Co.
The John Deere D-Series excavators are designed to get more done at less cost on earthmoving and material-handling jobs. These machines retain the features of their predecessors, while providing faster hydraulics, a redesigned cab, undercarriage enhancements and a new cooling system. The result is a boost in productivity and uptime, as well as lower daily costs. Power, smoothness, ease of operation and comfort ensure a fit for most excavating applications.
