The Cat® 330 UHD is a versatile urban demolition machine with large attachment capability for 5-6 story work. Equipped with the latest technology and stability monitoring system for ultra-high demolition work, this 46-ton working machine maintains efficiency with the retrofit boom, using Cat Payload measurement and Cat 2D Grade. Combined with the 15-minute boom swap, the hydraulic variable undercarriage makes the setup fast and gives operators more uptime.
Reach up to 20 m (65’6â€) with a 3300 kg (7,275 lb) demolition tool. Choose your retrofit booms with 1-piece and 2-piece options. Cat Payload, Cat 2D E-Fence, and Cat Grade technologies come standard for retrofit fronts.
The hydraulic quick disconnect requires no tools to swap booms. Choose your undercarriage—a 3 m (3'10") transportation width with fixed or hydraulic variable gauge undercarriage or a 3.4 m (11'3") wide undercarriage for extended stability on the job. Cat Next Generation Excavators share common parts and exceptional service.
The deluxe cab tilts for a more ergonomic operator station and a better view of the task at hand. Equipped with standard P5A high-resistance glass and Operator Protective Guards (OPG) for safety. It also features a premium seat for comfort, while a 254 mm (10 in) color touchscreen indicates easy-to-read stability monitoring system information.

| Note (1) | Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 2,200 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture. |
| Note (2) | ¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations†(SEBU6250) for details. *Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. |
