The Link-Belt 36.3-ton 350 X3 full-sized model from LBX has been completely redesigned with a ROPS-certified cab and interior, new Interim Tier 4A engine technology and up to 10-percent better fuel efficiency, more lift capacity, faster cycle times and improved serviceability.
Komatsu’s PC390LC-10 is an environmentally-friendly excavator with increased power and decreased fuel consumption. All Tier 4 Interim machines come standard with Komatsu CARE, a complimentary maintenance program that can ease the cost of buying or leasing a Tier 4 Interim machine, and increase residual values on lease returns and used equipment.
The tail swing radius on the Doosan 14-ton DX140LCR is 4 feet 10 inches, allowing the excavator to work on congested jobsites such as streets, highways and rail lines without blocking traffic in adjacent lanes or tracks. At the same time a track length of 12 feet 4 inches provides exceptional stability for digging and lifting operations.
Six excavators with Tier 4 Interim engines make up John Deere’s new G-Series line. Models include: 250G LC, 290G LC and 350G LC (188 to 271 horsepower) and the larger 470G LC, 670G LC and 870G LC (463 to 532 horsepower) with Deere’s exclusive Powerwise III engine management system.
LiuGong’s D-Series generation of intelligent crawler excavators – models 915D, 925D and 936D – feature computer-aided systems for greater operating efficiency, lower fuel consumption and overall reliability. “Smart” hydraulic systems produce standout, on-demand breakout power, while a rugged new frame design and improved undercarriage components make the D-Series excavators stable and durable.
Caterpillar’s 336E hydraulic excavator replaces the 336D with a 12-percent more powerful engine and 4-percent faster cycle times than the previous model. The SAE 300-horsepower Cat C9.3 ACERT engine meets Tier 4 Interim emissions standards and improves fuel efficiency by 2 percent. Greater hydraulic pressure in heavy-lift mode boosts lift capacity by 5 percent.
The Bobcat minimal-tail-swing E80 compact excavator features a standard long-arm configuration and roomy cab with a fully-adjustable Super Deluxe seat. The automotive-style climate control system keeps you comfortable. The E80’s 250-hour greasing intervals allow contractors to remain productive longer.
Hyundai Construction Equipment Americas (HCE) has improved its excavators from 14 metric tons and higher by including many optional features as standard equipment. HCE includes features such as Hi-mate Remote Management Systems, CAPO Computer Aided Power Optimization Systems, hands-free phone and other comforts as standard equipment.
The new Volvo EC300D excavator is a heavy-duty machine with an operating weight of 66,140 to 73,630 pounds and a breakout force of 45,970 pounds. With a Tier 4 Interim certified engine, the powerful and reliable excavator excels in heavy digging and lifting duties, offering superior cycle times and greater fuel efficiency. Fitted with Contronics, the advanced mode selection system, operators can choose from five working modes that best suit the job.
