Caterpillar 336 Series

Next Generation, 36-ton Excavator Increases Efficiency, Lowers Operating Costs

Caterpillar introduced two models in its new Next-Generation, 36-ton size class excavators: 336 and 336 GC.

Delivering high-production performance, Cat 336 features the most power and lift capacity of the two models. The result is maximum productivity at the lowest cost. Cat 336 GC combines the right balance of productivity features with reduced fuel consumption and maintenance costs, resulting in high reliability and low-cost-per-hour performance.

The 336 has the industry’s highest level of standard factory-equipped technology, including integrated Cat Connect to boost operating efficiency by up to 45 percent over traditional grading operations. The standard Cat Grade with 2D system provides guidance for depth, slope and horizontal distance to grade through the standard touchscreen monitor, for more accuracy.

Standard Grade Assist automates boom, stick and bucket movements so operators can effortlessly stay on grade with single-lever digging. Cat Payload delivers precise load targets and increased loading efficiency with on-the-go weighing and real-time payload estimates to prevent truck over/underloading.

By design, Cat Next Generation excavators consume less fuel than the models they replace. For the 336, it’s up to 15 percent less.

New Smart mode operation automatically matches engine and hydraulic power to digging conditions, optimizing both fuel consumption and performance. Engine speed is automatically lowered when there is no hydraulic demand to further reduce fuel usage. The cooling system features a new fan that runs on demand to keep the excavator working at the correct operating temperature for maximum efficiency.

With a new electrohydraulic system built for responsiveness and efficiency, the Cat 336 and 336 GC feature a new main control valve that eliminates the need for pilot lines, reduces pressure losses and lowers 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. The hydraulic return filter has a 3,000-hour service life—a 50 percent increase over the previous filter.

The fuel system filters are synchronized for service at 1,000 hours—100 percent more than previous filters. With fuel system water and sediment drains, and hydraulic system oil level positioned close together at ground level, routine daily maintenance is faster, easier and safer.
