Key Specs
The Cat® 323 combines speed, efficiency, and power. Standard technology right from the factory help boost operator efficiency by up to 45%. Combine these features with a new cab, longer maintenance intervals and reduced fuel consumption to lower maintenance costs by up to 15% and fuel consumption by up to 20%.
A precise combination of lower engine speed and a large hydraulic pump delivers top performance while burning less fuel.
Extended and more synchronized maintenance intervals increase uptime and reduce costs compared to the previous model.
Offering the industry’s highest level of standard factory-equipped technology, including Cat Grade with 2D, Grade with Assist and Payload.
