Features
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 percent.
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.

Leverage Caterpillar connected data and security principles to improve efficiencies, increase productivity and make your business more profitable.
Cat Command is an excavator safety feature that allows you to operate at a distance up to 400 meters (437 yards) away via remote control. The Command remote controller communicates with the excavator's dedicated remote radio to perform functions you require and can be programmed for personal operating preferences.

Cat 2D E-fence is an excavator safety feature that keeps the front linkage within a predefined work area to avoid hazards such as traffic. 2D E-fence uses data from position sensors to automatically stop motion when the front linkage reaches the operator defined boundaries.
Cat Lift Assist is an excavator safety feature that quickly calculates the actual load you are lifting and compares it to the rated load the excavator is capable of handling. Visual and auditory alerts tell you if you are within safe working range or need to take action to avoid tipping.
