Next Generation excavators from Caterpillar® increase productivity, lower fuel and maintenance costs, and improve operator comfort. In its 36-ton class, the new Cat® 336 provides the industry’s highest level of factory-equipped technology to boost overall operating efficiency by up to 45 percent. The machine’s Smart Mode operation automatically matches engine and hydraulic power to digging conditions, and the cooling system uses an on-demand fan that keeps the excavator working at the correct operating temperature. The result is up to 15% less fuel consumed.
