Product Focus: Excavators

Case D Series excavators

D Series excavators 
Case Construction Equipment adds the CX490D and CX500D to its D Series excavator line. They offer 10 percent faster cycle times, improved responsiveness, multifunctional controls and greater fuel efficiency. An electronically controlled hydraulic system boosts breakout forces, increases lift capacity and improves responsiveness. The CX490D weighs 109,300 pounds and has a digging force of 55,500 to 60,700 foot-pounds; the CX500D weighs 111,800 pounds and has a digging force of 64,500 to 70,400 foot-pounds. The 362-hp. engine is Tier 4 Final-compliant.

Cat excavators

Greater productivity, fewer emissions
The Cat 336F excavator is Tier 4 Final compliant and offers enhanced fuel efficiency. Electric boom and stick regeneration valves capture and recycle energy and an engine idle shutdown engages after a specified amount of idle time. The operator can touch one button to idle engine speed or use the economy power mode to conserve fuel. The C9.3 ACERT engine has an exhaust aftertreatment regeneration system that assures the machine works normally without operator intervention. Simple to maintain, most service points are at ground level. Weighing 80,500 to 86,600 pounds, the unit has a dig-out force of 41,570 pounds.

Doosan excavators

Tier 4 compliance plus other updates 
Two new Doosan excavators feature Tier 4-compliant engines and improved performance, operator-focused comfort, fuel economy and job site durability. The 14-metric-ton DX140LC-5 and DX140LCR-5 machines replace the interim Tier 4 “dash-3” models. The DX140LCR-5 has a shorter tail swing; both models have a reinforced superstructure and permanently sealed and lubricated track links. Smart Power Control (SPC), made up of Variable Speed Control and Pump Torque Control systems, improve machine efficiency. Other updates include improved anti-skid plates; relocated emergency engine stop; improved serviceability; upgraded alternator and new front window design. 

Hitachi excavator

Excavator for rental operations 
The Hyundai HX300L 35-ton excavator features a Tier 4 Final-compliant, 230 horsepower Cummins QSB6.7 diesel engine with a maximum dig depth of 24 feet 3 inches, bucket digging force of 37,920 foot-pounds and maximum reach at ground level of 32 feet 3 inches. It offers up to 13 percent faster cycle speeds and up to 10 percent better fuel efficiency than previous Hyundai models. It offers three modes: Power for heavy work; Standard for general work; and Economy for light work. The All Around View Monitoring (AAVM) system provides a 360-degree virtual operating view and the Intelligent Moving Object Detection (IMOD) system warns when objects come within 16.5 feet of the machine. Hydraulic pump output can be optimized to match flow rate to the attachment.

JCB Zero tailswing excavator

Towable, zero-tailswing excavator
The JCB 45Z-1 zero-tailswing excavator can be transported with a pick-up. It has a longer main boom and shorter dipper arm than the 8045 ZTS, providing a dump height of 13 feet 1 inch. The hydraulic system delivers up to 8,532 pounds of bucket breakout force and dipper breakout force of 4,945 pounds. Graphite bushings offer 500-hour greasing intervals. It features H-frame undercarriage construction; customizable digital instrumentation; 48 horsepower Tier-4-Final JCB diesel engine by Kohler; and programmable auxiliary hydraulic flow settings. New Eco buckets offer improved material retention and new pin pick-up points fit other bucket brands. The unit offers reduced noise and vibration levels. It offers nine power modes, including Eco and H+ heavy-digging mode. A Lift Overload system alerts the operator when the load approaches or exceeds overload conditions.

John Deere excavators

Versatile excavators updated
The updated John Deere 75G and 85G excavators feature hand-controlled proportional auxiliary hydraulics and ability to use backhoe buckets. The units feature a pattern changer, rubber pads and standard blade. They are powered by 57 horsepower Final Tier 4 diesel engine with automatic diesel particulate filter (DPF). They have a spacious, comfortable, all-around visibility cab with LCD monitors that are easy to use. Optional rubber track pads or heavy-duty rubber belts allow the machines to work on paved surfaces. A variety of track-widths, buckets and other options are available.

Kobelco excavator

Excavator delivers power, performance 
The Kobelco SK300LC-10 68,100-pound excavator is powered by a 252 horsepower Tier 4 Final-compliant Hino engine and has 37,300 foot-pounds bucket digging force while minimizing fuel consumption. A hydraulic regeneration system reuses force generated by the boom in the arm. To handle that additional power, a high boom-foot cross-section, thick arm-foot base plate and strong foot bases offer reinforcement. Its travel motor increases traction force by 10 percent without sacrificing travel speed. The Kobelco-exclusive independent travel feature allows the machine to move, lift and swing simultaneously without loss of power. Automatic swing priority instantly delivers full swing power during combined operations. Telematics improve operating lifecycle costs; the system also extends service intervals for oil and filter changes and greasing.

Komatsu excavator

All-purpose excavator 
Komatsu America Corp.’s PC210LC-11 excavator with a 165 horsepower Tier 4 Final-certified SAA6D107E-3 engine delivers up to seven more horsepower and uses up to six percent less fuel than its predecessor. A new fan clutch improves cooling efficiency and helps reduce noise levels. It has three travel speeds and its 9,634-pound standard counterweight improves front- and side-lift capacity. A pattern change valve makes switching joystick patterns simple. Six work modes match engine speed and pump flow to applications. The Komatsu Closed-Center Load Sensing System (CLSS) provides quick response and smooth operation. The OPG Level 1-certified cab makes it one of the quietest cabs in its class and Operator ID provides Komtrax data by job, application or operator and provides operating information. Centralized engine checkpoints provide easy access to engine oil, filters and drain valves.
