CATERPILLAR has debuted its latest excavators – the Next Generation 330 and 330 GC.
The 30-ton (27.2-tonne) size class excavators are described by the manufacturer as offering increased operating efficiency, lower fuel and maintenance costs, and improved operator comfort to previous models.
The new machines offer “unique” combinations of features, which aim to match contractors’ productivity and cost targets, according to Cat.
The 330 features integrated Cat Connect technology and offers the most power and lift capacity of the two models, while the 330 GC combines productivity features with reduced fuel consumption and maintenance costs, which aim to provide high reliability and low-cost-per-hour performance.
The Cat 330 is said to increase operating efficiency by up to 45% over traditional grading operations, due to its integrated Cat Connect technology.
The standard Cat GRADE with 2D system provides guidance for depth, slope, and horizontal distance to grade through the standard touchscreen monitor. The system is upgradable to Cat GRADE with advanced 2D or Cat GRADE with 3D. Standard grade assist automates boom, stick, and bucket movements, which aims to allow operators to stay on grade with single-lever digging.
Other features include Cat Payload, which is said to deliver “precise” load targets and increased loading efficiency; e-fencing, which prevents the excavator from moving outside operator-defined set points; and Cat LINK hardware and software, which connects job sites to the office and provides managers with operating information.
Cat said that the Next Generation excavators are designed to consume less fuel 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, while engine speed is automatically lowered when there is no hydraulic demand. The excavators also feature a new main control valve that is said to eliminate the need for pilot lines, reduce pressure losses, and lower fuel consumption.
The new Cat air filter with integrated pre-cleaner and primary and secondary filters has double the dust holding capacity of the previous design, and the new Cat hydraulic filter has a 3,000-hour service life. Fuel system filters are synchronised for service at 1,000 hours.
All Next Generation Cat excavator cabs come equipped with standard features including keyless push-start button; touchscreen monitor with job dial keys; and sound-suppressed rollover protective structures.
