Caterpillar has launched its Next Generation 36-ton size class excavators – the 336 and 336 GC – increasing operating efficiency, lowering fuel and maintenance costs and improving operator comfort

The Next Generation 36-ton size class excavators from Caterpillar boosts three major benefits compared to previous models: up to 45 per cent more operating efficiency for the 336, which boasts the industry’s highest level of standard factory-equipped technology to increase productivity, up to 15 per cent more fuel efficiency (336), and up to 15 per cent maintenance cost reduction. The new excavators offer unique combinations of features designed to match contractors’ productivity and cost targets.

The new Cat 336 is equipped with integrated Cat Connect Technology and features the most power and lift capacity of the two models. The result is maximum productivity at the lowest cost.

The standard Cat Grade with 2D system provides guidance for depth, slope, and horizontal distance to grade, making operators more accurate and 45 per cent more efficient over traditional grading operations. The system can be upgraded to Cat Grade with Advanced 2D or Cat Grade with 3D. There is also an E-fence feature that prevents the excavator from moving outside operator-defined set points.

Fuel efficiency

The 336 and 336 GC new excavators produce more work per unit of fuel than the models they are replacing - up to 15 per cent more fuel efficiency for the 336.

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

The Cat 336 and 336 GC feature a new main control valve that eliminates the need for hydraulic pilot lines, reduces pressure losses and lowers fuel consumption. In addition, less oil is required, lowering long-term operating costs.

New filters

With extended and more synchronised maintenance intervals, the new Cat excavators reduce maintenance costs by up to 15 per cent over the previous series. A new Cat air filter has double the dust holding capacity over the previous design, the hydraulic return filter has a 3,000 hour service life and the fuel system filters are synchronised for service at 1,000 hours.

New deluxe cabs

With a choice of comfort or deluxe cabs, features include keyless push-button start, large standard 8 inch touchscreen monitor with jog dial keys for control, and sound-suppressed rollover protective structures to offer premium operator comfort and safety. New advanced viscous mounts reduce cab vibration by up to 50 per cent, compared with previous versions.

With the 336 only, there is optional 360-degree visibility, combining images from multiple machine-mounted cameras to enhance the operator’s sight lines in all directions.
