The engine oil filter, remotely located in the pump house, is easy to change without the need to go underneath the machine. The hydraulic oil filter provides 100-percent continuous flow filtration of all hydraulic oil on the return line. Flip-open service panels provide easy access to virtually all key components.
The Kobelco SK850LC Super ACERA full-size excavator has four standard working modes for enhanced performance. The H Mode allows heavy digging and high productivity while the S Mode delivers standard digging and increased fuel savings. The B Mode powers one-way flow attachments, and the A Mode powers attachments that require two-way flow. The excavator can easily be configured four different ways for shipping and transport to meet varying local requirements – reducing the time, cost and number of trucks needed to move to a job site. The SK850LC is designed to simplify routine maintenance checks, thus increasing productivity and decreasing downtime. 630.260.4000, www.kobelcoamerica.com
The New Holland E175B Tier 3 excavator raises the bar on productivity and operator comfort, delivering more horsepower and unsurpassed grading and finishing capabilities with Intelligent Total Control System (ITCS) technology. The E175B excavator features an operating weight of 37,800 pounds, a maximum dig depth of 21 feet, 5 inches and a bucket breakout force of 24,900 foot/pounds. Powered by a quiet, fuel-efficient 121-hp engine, this excavator uses proven FPT diesel engine technology that includes direct injection with an intercooler turbo charger. The result is high horsepower and high torque levels at surprisingly low rpms. The E175B provides four work modes: H Mode for heavy-duty excavation work, S Mode for standard digging and loading work, B Mode for breaker work, and A Mode for demolition work with crusher/nibbler-breaker. The E175B delivers complete operational control, maximum comfort, progressive hydraulic acceleration and a clear view of the job site. Superior cab refinements reposition controls for easier accessibility and include a backlit monitor for improved daytime visibility, along with quick access to operator controlled settings and diagnostics. www.newholland.com
The Zaxis 450LC-3 boasts a Tier-3-certified, six-cylinder Isuzu engine for greater output — 348 net peak hp at 1,800 rpm — and considerable reduction in fuel consumption through a cooled Exhaust Gas Recirculation system and a common-rail fuel-injection system. The Zaxis 450LC-3 comes standard with the ZXLink Ultimate wireless communication system and three years of service. ZXLink Ultimate delivers machine hours, location, and geofencing capabilities, plus dashboard alerts, equipment utilization and fuel consumption data, diagnostic trouble codes, and more. 866.973.0394, www.hitachiconstruction.com
The C-Series excavator line has the more powerful Tier 3-certified Volvo engines, delivering exemplary fuel efficiency. The operator’s environment has been substantially upgraded, giving operators more comfort, more space, a better climate, better visibility and improved controls that are easier to use. These Tier 3 engines have Volvo Advanced Combustion Technology, which provides high torque at low revs, leading to ultra-efficient fuel consumption. Impossible to stall, the onboard computer balances maximum available power to hydraulic output, preventing the engine from becoming overloaded (regardless of engine speed or pump demand). Improvements include: standard CareTrack; advanced hydraulic flow; better controls, more space, more glass, less noise and vibration. 828.650.2000, www.volvo.com
The Cat 336D L Hydraulic Excavator features a standard heavy lift circuit — at the touch of a switch, heavy lift will boost hydraulic pressure for increased lift performance. The 336D L has a maximum operating weight of 82,962 pounds and net power of 268 hp. The Cat C9 engine powers the 336D L and meets U.S. EPA Tier 3 emissions regulations. To enhance durability in demolition applications, the 336D L can be equipped with heavy-duty triple grouser tack shoes for long wear and solid traction.Track guards for the sprocket end and idler end are fitted to protect the full length of the track. Rubber bumpers attached to the sides of the excavator reduce inadvertent damage when swinging, and bottom and bearing guards protect those areas from damaging debris. Additional cab guarding includes a full-length wire mesh window cover and a falling object guarding system. The spacious cab features glass affixed directly to the pillars to eliminate window frames and enhance visibility. A large skylight provides a view upward.
