Tracking New Opportunities
Increased power, reduced fuel requirements
John Deere says that its 270D LC excavator provides 188 SAE net horsepower with a 6.8L six-cylinder PowerTech Plus Tier III-certified diesel engine. Deere says that the unit features faster hydraulics, increased swing torque, and more drawbar pull to help boost production. The Powerwise III management system balances engine and hydraulic performance, with generous hydraulic flow and best-in-class metering ensuring powerful digging force, precise low-effort control, and multi-function operation, Deere adds.
Terex offers its TXC 420LC-2, a 93,480-pound excavator that is built on a deep, full-reinforced box section constructed with heavy-gauge steel plates for added ruggedness. The machine’s engine offers 293 horsepower while an electronic power optimizing system allows the operator to maximize work efficiency over a full range of operating conditions and to minimize fuel consumption. An automatic, two-speed travel system allows for high traction force and travel speed, and two working and two power modes are offered. The cab offers independent suspension, low noise levels, and high visibility. The front window slides up and stores in the roof, and the side window can be opened for ventilation.
Power and productivity
New Holland’s E215 is a 47,000-pound excavator with 148 horsepower and a bucket capacity of .63 to 1.8 cubic yards. The company says that the excavator offers exceptional controls that improve on-the-job efficiency. One of those features is the independent travel system. While lifting and carrying objects may be a sensitive operation, this feature is said to make these tasks easier by reducing the need to “feather” the controls. A separate pump is dedicated to the travel system so that the excavator doesn’t lose speed when raising the load while traveling. Another production-oriented feature is the power boost button that provides maximum breakout force when needed. A two-speed travel system allows for the use of a high-torque, low-speed setting for climbing and carrying, while a high-seed setting ensures rapid travel under other conditions.
