Extend Your Reach on the Jobsite with the New Caterpillar 330 Straight Boom Excavator


Expanding Caterpillar’s demolition excavator line offering, the new purpose-built Cat 330 Straight Boom excavator delivers performance in low-level building demolition applications.

Offering a maximum digging depth of 19.1 ft. (5.8 m), the new straight boom excavator features a maximum vertical reach of 40.9 ft. (12.48 m) – 8 ft. (2.45 m) higher than a standard Cat 330 excavator – for demolishing three-story buildings. The 330 SB is also matched to a range of demolition tools including hammers, multi-processors, demolition grapples, pulverizers and quick couplers. 

Standard Cat technologies for the new 330 increase machine versatility in demolition and excavating applications. Powered by the 275 hp (205 kW) Cat C7.1 engine, three power modes – Smart, Power and Eco – match engine and hydraulic power to the task. The excavator’s electrohydraulic system powers through different types of materials, while standard quick coupler, medium and high-pressure circuits allow for the use of a range of Cat demolition attachments.


The next generation demolition cab positions all machine controls in front of the operator to eliminate the need to reach backwards. Most machine functions – including joystick functions, pattern and response – are customized using the 10-in. (254-mm) touchscreen monitor. Operators view the standard rearview and right-hand-sideview camera feeds on the screen to see objects and personnel around the machine.

When excavating, depth and slope readings of standard Cat Grade with 2D technology are viewed on the monitor. Cat Payload technology – standard with bucket and optional with grapple attachments - offers real-time, onboard weight estimates for precise load targets and to avoid overloading and underloading. It can be combined with VisionLink for remote management of production targets. Cat Product Link provides machine operating data like location, hours, fuel usage and diagnostic codes.

Available remote excavator operation via Cat Command increases operating safety. Onboard electronics, vision systems and offboard controls give operators the same control response of operating inside the cab. Command kits provide the option of line-of-sight operation via the Command console or non-line-of-sight operation using the Command station.

Design and Maintenance

The new Cat 330 Straight Boom excavator features reinforced booms, sticks, frame and bucket cylinder guard for machine durability in demanding demolition applications. Standard for the next generation cab, operator protective guards shield the roof and front reinforced P5A laminated windows from falling debris during demolition while helping to maintain visibility. A sloped track frame prevents mud and debris accumulation to help reduce damage, while sealed track pins and bushings reduce travel noise and increase undercarriage life.

Harnessing technology, dealer service technicians can perform remote diagnostics and software updates on the 330. Remote Troubleshoot allows dealers to diagnose fault codes and machine issues without interrupting the production cycle. Remote Flash enables software updates to be pushed out to the machine and installed at a time convenient for the customer.

All fuel filters now feature extended, synchronized 1,000-hour change intervals and are grouped together for simplified maintenance. Long-life fuel, oil and air filters reduce excavator time in the shop, and hydraulic oil checks and fuel system purging of water are done from ground level. Operators can track filter life and maintenance intervals from inside the cab.
