Cat 323 Next Generation Excavator Safety

The real value of safety features

They’re moms and dads, sons and daughters, friends and neighbours—and they work for you. Together, we strive to send them home safely at the end of every shift. Support your safety goals with a new generation of Cat 323 construction excavators, designed to protect people and profits.

Reduce risks, increase profits
Safer is smarter

Protection in all directions

The standard 2D E-fence technology feature automatically stops excavator motion using boundaries you set in the monitor for the entire working envelope—above, below, sides and front. E-fence features protect equipment from damage and reduce fines related to zoning or underground utility damage. Automatic boundaries even help prevent operator fatigue by reducing over-swinging and over-digging.

Look out for your environment and equipment
Cat Next Generation Excavators Maintenance Features

Maintenance costs reduced by 15%

Maintenance is a pain and not just because of the downtime, but because there are parts to order, procedures to follow, fluids to dispose of—all for a machine that seems to be running just fine. It’s no wonder some equipment owners ignore the intervals. But that can be an expensive decision.

The Cat® 323 Excavator easy-maintenance design has extended, more synchronized maintenance intervals. Filter locations that make sense. Checkpoints you can reach without climbing all over the iron. Plus increased capacity and longer life hydraulic, air and fuel tank filters. That’s why new Cat Excavators feature a maintenance plan you’ll want to follow. One that lets you work more, stop less and lower costs up 15 percent.
