Key Features

More Comfort. More Performance. More Versatility.

Productivity in Overdrive

Powerful hydraulics provide strong digging force and swing torque for large payload capacities, making the 336 a standout performer in its size class.

Dependable Demanding Durability

Reinforced booms and sticks take on challenging and heavy work, while the standard, heavy-duty reinforced undercarriage expertly absorbs the stress between jobsite terrain and machine.

Does the Heavy Lifting for You

Need more lift during your shift? Auto heavy lift gives you more power and maximizes the 336’s lifting capabilities exactly when you need it for as long as you need it.

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 2,000 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.
