Komatsu America’s 242-horsepower PC300LC-7 Power Plus excavator offers improved lift capacity and more efficient use of the machine’s arm-crowd and bucket-breakout forces. With extra upper frame reinforcement and increased counterweight mass, the unit features an additional 2,500 pounds on the rear bias for improved stability in all digging applications.
In comparison to the standard PC300LC-7 model, the Power Plus unit offers an 8.2 percent improvement in front lifting capacity and a 10.8 percent improvement over the side (based on a 13-foot-2-inch arm, 25-foot reach from swing center at ground level and lifting mode in use). The additional counterweight gives the machine the ability to fully realize its 37,040-pound usable arm crowd force and 44,970-pound breakout force with the 10-foot-5-inch arm.
Also new from Komatsu: The company’s Tier 3 engines will reduce emissions while improving fuel efficiency by up to 15 percent. The engines will feature a new combustion chamber, designed for better air/fuel mixing and optimal combustion.
