Cat improves excavator efficiency


Caterpillar has unveiled details of its next-generation 36-ton class excavators.

Compared with previous modes, the new Cat 336 and 336GC feature increased operating efficiency, lower fuel and reduced maintenance costs, as well as improved operator comfort.

A Cat spokesman said, “The new Cat 336 has the industry’s highest level of standard factory-equipped technology to boost productivity. Integrated Cat Connect technology increases operating efficiency by up to 45% 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, making operators more accurate. The system is readily upgradable to Cat Grade with Advanced 2D or 3D.”

Operators are able to easily remain on grade with single-lever digging using the standard grade assist that automates the boom, stick and bucket movements. In addition, the Cat Payload means precise load targets and increased loading efficiency can be achieved as on-the-go weighing, preventing the truck from over- or underloading.

Reduced fuel consumption
The excavators consume 15% less fuel than the outgoing models due to a number of features included on the machines.

A smart mode operation automatically matches the engine and hydraulic power to the present digging conditions, optimizing both fuel consumption and performance, while engine speed is automatically lowered when there is no hydraulic demand.

In addition, the cooling system has a new fan that runs only on demand, to ensure the vehicle is working at the correct operating temperature.

The Cat 336 and 336 GC also feature a new main control valve that eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption, while fewer hydraulic lines on the excavators result in less oil required, lowering long-term operating costs.
