The new Cat 330 30-tonne excavator

Caterpillar has launched the 300 and 330 GC next-generation 30-tonne size class excavators.

The manufacturer claims the two new machines increase operating efficiency, lower fuel and maintenance costs, and improve operator comfort compared to previous models.

The new excavators offer unique combinations of features designed to match contractors’ productivity and cost targets.

The Cat 330 features standard integrated Cat Connect technology and the most power and lift capacity of the two models. Caterpillar says that the Cat Connect technology increases operating efficiency by up to 45% over traditional grading operations.

The Cat 330 GC combines a balance of productivity features with reduced fuel consumption and maintenance costs.

Cat says its next-generation excavators are designed to consume less fuel per unit of work than the models they are replacing — up to 20% for the 330 compared to the 330F and as much as 15% for the 330 compared to the 330D2.

New smart mode operation automatically matches engine and hydraulic power to digging conditions, with the intention of optimising both fuel consumption and performance. To further reduce fuel usage, engine speed is automatically lowered when there is no hydraulic demand. The excavators feature a new main control valve that eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption.

The new cooling system employs auto-reversing electric fans, which independently monitor hydraulic oil, radiator and air-to-air aftercooler temperatures to deliver the exact airflow required.
