Caterpillar presented an onslaught of new machines—24 to be exact—at its Edwards Demonstration and Learning Center in Peoria, Ill., during its annual year-end press briefing.

Sticking with the “more choices” theme, the new 330 and 336 hydraulic excavators are also offered in a GC trim level—basically simplified versions that don’t require all the performance and technology required of machines that operate in more extreme applications.

The Cat 330 has a larger, 6700-kg (14,770-lb) counterweight, which enables the excavator to lift nearly 10% more than the 330F and up to 15% more than the 330D2. With increased swing pressure, a larger swing drive, and larger swing bearing, the 330 delivers a 5% increase in swing torque over the previous series.
