Medium & Large Excavators: Equipment Spotlight

Medium and large excavators from Kobelco, John Deere, Doosan, Volvo, Hitachi, Case and Caterpillar.

The new full-size excavator, the SK485, is the largest of the Kobelco Mark 9 excavator series. The Tier 4 SK485 Mark 9 delivers up to 15-percent improvement in fuel efficiency, while maintaining exceptional productivity. A new ROPS/FOPS cab provides a larger, more comfortable work environment. A low engine cover and standard rear-view camera improve visibility and operator productivity. Plus, the new CEGR solution will achieve lower operating costs, while also maintaining efficiency, performance, power and reliability. The SK485 features an operating weight of 111,774 pounds, and a dig depth of 25 feet 7.5 inches. The new model delivers 345 hp. 630.260.4000,

John Deere

The 180G LC hydraulic 18 metric ton excavator provides contractors a larger mid-size excavator solution with an Interim Tier4-certifed (IT4) engine. The 180G LC features a rugged, 121 hp, field-proven IT4/EU Stage IIIB John Deere PowerTech diesel engine that meets rigid emissions regulations, enabling operators to work anywhere jobs are available, including non-attainment areas. The 180G LC comes equipped with a Powerwise III hydraulic management system that yields pinpoint metering and smooth, low-effort control. The Powerwise III perfectly balances engine performance and hydraulic flow for predictable operation. Three productivity modes allow an operator to choose the digging style that fits the task at hand. High-productivity delivers more power and faster hydraulic response to move material. Power delivers a balance of power, speed, and fuel economy for normal application and economy reduces top speed and helps save fuel. 800.503.3373,


The Doosan DX350LC excavator features a 281-hp engine, a 77,603-pound operating weight and a 41,667-pound arm digging force. Built for the most rugged conditions, this excavator features significant power and performance increases to go along with its interim Tier 4 status.

Volvo Construction Equipment

Part of the new generation D-Series of excavators, Volvo CE is offering customers three heavyweight production machines, ranging in weight classes between 75,000-111,800 pounds – the EC340D, EC380D and EC480D excel in heavy digging and lifting duties, offering superior cycle times and greater fuel efficiency. At the heart of these machines is a turbocharged high pressure direct injection Volvo diesel engine that offers maximum power of 279 hp (EC340D/EC380D), and 343 hp (EC480D) respectively. All three machines feature an automatic idling system that reduces engine speed when the levers and pedals are not activated – aiding fuel efficiency and lowering external noise. The larger EC480D features mechanical variable width tracks, which extend the width by 6 inches and raise clearance by 8 inches, aiding stability and protection. 825.650.2000,


Whether your work is urban renewal, street repair, or underground utilities, the new reduced-tail swing Hitachi ZX245USLC-5 opens up a wide range of possibilities since it can work in and around obstacles, and on congested jobsites.The ZX245USLC-5, with its increased weight and arm and dig forces, provides noticeably more muscle than its predecessor. It also utilizes three pumps and a new hydraulic valve to improve both productivity and smoothness. 866.973.0394,


The new CX470C excavator is the newest in the Case C Series excavator line that features increased fuel efficiency, productivity and improved serviceability and operator comfort. To achieve Tier 4 Interim certification, the Case CX470C excavator features cooled exhaust gas recirculation (CEGR) technology that burns cleaner while delivering superior horsepower. The CX470C, rated at 362 net hp, is available in Long Undercarriage (LC), Retractable Undercarriage (RTC) and Mass Excavator (MEX) models, with operating weights ranging from 105,300 to 108,600 pounds. The CX470C models are roughly 1,100 pounds heavier than the previous model for improved capacity. The CX470C MEX is designed for heavier loads and larger buckets (up to 4.13 yd3 or 3.16 m3), achieving higher productivity in large excavation jobs and high-volume truck loading. The Retractable Undercarriage version provides undercarriage width adaptability for transport between jobsites. 262.636.6011,


Caterpillar has unveiled the first model in its new line of hybrid excavators, the Cat 336E H, which will be sold and serviced exclusively through the global Cat dealer network following the machine’s official launch at bauma 2013 in Munich, Germany. The 336E H has all of the same powerful advantages of the 336E with the biggest difference between the two models being even greater fuel efficiency. To achieve added fuel savings, the design of the 336E H uses three building block technologies that 1) conserve fuel with engine power management via the Cat Electronic Standardized Programmable (ESP) pump, which smoothly transitions between the hydraulic hybrid power sources, engine and accumulator; 2) optimize performance using restriction management via the patented Cat Adaptive Control System (ACS) valve, which intelligently manages restrictions and flows to seamlessly control machine motion with no loss of power, and to ensure operators experience no difference in control, hydraulic power or lift capability; and 3) reuse energy via the hydraulic hybrid swing system, which captures the excavator’s upper structure swing brake energy in accumulators, and then releases the energy during swing acceleration.
