Caterpillar Excavators
Cat’s Next Generation excavators are up to 25 percent more fuel efficient than their predecessors.

Caterpillar’s Next Generation excavators — including the 320 GC, 320, and 323 — are said to offer 20 to 25 percent fuel savings over their predecessors. A new Smart mode operation automatically matches engine and hydraulic power to digging conditions to optimize fuel consumption and performance. Maintenance costs are also cut, by up to 15 percent over previous models, by extended and more synchronized maintenance intervals on the new machines. The excavators are equipped with Next Generation Cat Excavators cabs that offer standard features including keyless push-button start, an 8-inch touchscreen monitor with jog dial keys, and sound-suppressed rollover protective structures. The 320 and 323 models include what Cat describes as the industry’s highest level of standard factory-equipped technology. Both have Cat Connect Technology, which is said to increase operating efficiency by up to 45 percent over traditional grading operations. Cat Grade 2D is also standard and offers guidance for depth, slope, and horizontal distance to grade. Standard Grade Assist automates boom, stick, and bucket movements. Cat Payload offers precise load targets for increased efficiency, while Cat Link hardware and software connects sites to the office.
