` – the total “system” comprised of intelligent electronics and functional hydraulics – controls, regulates and coordinates all key systems of the excavator. Powerful – turbo-charged and after-cooled 12 cylinder diesel engine, with direct injection and low operating RPM. Productive – optimum utilization of available engine output via electronic engine speed sensing pump regulation. Increased work speed through pump flow summation. Operating safety – the electronic engine-speed-sensing control protects the engine from overload. Pressure – and flow compensation eliminate unnecessary oil circulation and consequently avoid excess heat as well as component wear.
Comfortable – large well equipped, air conditioner and sound insulated cab. Seat and joystick console independently adjustable to individual operator’s size and weight. Environmentally sound – low noise and exhaust emission. Optional: Bio degradable oil. Easy service – clear and easy access to all components. Large catwalks, steps and platforms. Sealed attachment pivots, central lubrication system and extended service intervals reduce maintenance costs. Versatile – different lengths of gooseneck booms, assortment of sticks and an extensive variety of buckets, bottom dump shovels and grapples provide application versatility. Economical – the combination of all the above, results in top performance at low operating costs. ` This is .

Diesel engine The heavy duty, water-cooled, turbo-charged and aftercooled Cummins Diesel engine delivers superior power and high power reserves. Its low operating speed results in lower fuel consumption, reduced emissions and an extended engine life. The enclosed engine compartment is easily accessible through full sized, easy to open doors and permits “walk in” access to all components for easy service.
Litronic-System The electronic engine-speed-sensing pump regulation allows full utilization of the engines available output, independent from external influences. The variable displacement axial piston pumps are fitted with an electro-hydraulic regulator which reacts in fractions of a second to the changing requirements of power or speed. Flow compensation reduces pump flow to a minimum when joystick levers are in neutral, avoiding excess heat and energy loss. The same effect is achieved with pressure compensation which minimizes pump flow prior to reaching maximum operating pressure. An automatic oil flow optimizer assures efficient power distribution to each individual function. The operators comfort and efficiency is enhanced by the LED display and monitoring system. It monitors all vital machine functions and includes a variety of automatic safety features. The Litronic system offers extensive customer benefits, such as improved efficiency, reduced fuel consumption and overall economy.
Undercarriage An overall low center of gravity for the machine is achieved through favorable weight distribution of the machine’s undercarriage, upper structure and attachment. This low center of gravity, combined with a wide undercarriage base, provides excellent stability for smooth, precise work and efficient transmission of the high dig and breakout forces. It also increase the life expectancy of undercarriage components. Standard bolt-on track chain guides on each side frame protect and improve the life expectancy of track components. The two side frames are removable for easy transportation. Carbody and side frames are connected with a unique “hook and key” design, which shortens and simplifies assembly.
More Benefits Through Advanced Techno 4
Cab The raised, spacious and comfortable cab features oversized, tinted windows and offers an excellent view of the trucks being loaded and general all-around visibility. The comfortable, air suspended and shock absorbed seat is adjustable to each individual operators size and weight. An air conditioner, integrated into the cab roof, is standard and increases operator comfort even in the most adverse conditions. A falling object protective structure (FOPS) is integrated into the roof. The control and instrument is within easy view of the operator. Service and control indicators, combined in a display screen, conveniently and continuously informs the operator, via symbols, of all machine functions. Effortless and precise joystick levers are comfortably integrated into the seat console.
Attachments Strict use of fine grain alloy steel plates, true hollow box structures and large size cast steel components in high stress areas result in strong attachments with high availability and long life expectancy. Widely spaced pivots in the attachment allow the use of two short, large diameter, hardened and chromed pins and low wear, high alloy steel bushings. Completely sealed, floating pins and bushings increase lubrication intervals and attachment availability. Shovel and backhoe buckets are especially strong and wear resistant. The optimized bucket shape achieves a faster and higher degree of fill. A number of different length sticks, booms and various size buckets allow the machine to be tailored to all types of materials and applications.
Swing Drive Swing acceleration of the upper carriage is accomplished via an axial piston motor flanged to a Liebherr planetary reduction gear. The swing pump and swing motors are linked in an independent closed-loop circuit. This system produces high swing torque, fast swing accelerations and deceleration, requires less power and shortens cycle times. The high swing torque created by the Liebherr planetary reduction gear, is transmitted to the Liebherr swing ring which features internal teeth for maximum protection from external damage and contamination. The swing operation is independent from all other travel and attachment functions.
