Cat says its next generation of 30-ton excavators not only improve on the previous models in several key areas, but also lower operating costs.
The company has introduced the new 330 and its more affordable counterpart, the 330 GC. You can see how these two models compare in the spec listing below. We will focus on the 330 being the machine Cat provided details on.
For starters, thanks to a new, larger 14 770-pound counterweight, the new 330 can lift almost 10% more than the 330F and up to 15% more than the 330D2. The machine also features increased swing pressure, a larger swing drive and a larger swing bearing, delivering a 5% increase in swing torque over the previous generation machine.
Powered by a 275-horsepower Cat 7.1, Cat says the new 330 also offers significant fuel savings over previous generation models. The new machine consumes 20% less fuel than the 330F and 15% less than the 330D2.
Aiding in this decreased fuel use are a couple new features. The new Smart Mode matches engine and hydraulic power on the 330 to digging conditions. The feature also lowers engine speed automatically when there is no hydraulic demand on the machine. The 330 also features a new main control valve that eliminates the need for pilot lines and reduces pressure losses, all while lowering fuel consumption.
Cat says the technology on the new 330 can increase an operator’s efficiency by up to 45% over traditional grading operations.
Cat’s GRADE with 2D system comes standard on the 330 and, using the touchscreen monitor, provides guidance for depth, slope and horizontal distance to grade. The standard Grade Assist feature automates the machine’s boom, stick and bucket movements for single-lever, on-grade digging. The system can be upgraded to support Advanced 2D or 3D grading.
The machine is also equipped with Cat Payload, which helps prevent over and underloading of trucks. The system provides precise load targets, on-the-go weighing and real-time payload estimates.
The excavators are currently available in North America, Europe, South Korea, Australia and New Zealand.
