325 Heavy-Duty Undercarriage Configuration -  Heavy-Duty Stability. Built for Demanding Terrain.*

    
• When the jobsite demands more muscle, the latest heavy-duty (HD) Cat 325 Excavator delivers. Built with an oversized long undercarriage and a robust 203 mm (8 in) track pitch, it’s engineered for outstanding stability and durability in harsh, uneven ground conditions.
    
• A 7,500 kg (16,350 lb) counterweight enhances balance and control, even when equipped with optional attachments such as a blade, Variable Angle boom, heavy-duty stick, bucket thumbs, or quick coupler. Advanced travel motors improve grade-climbing power, while upgraded swing motors and bearings ensure strong, smooth swing performance—even on slopes.
    
• Operators still get all the benefits they expect from a Cat 325: factory-integrated technology to boost productivity, extended maintenance intervals help keep owning and operating costs low, and electro-hydraulic efficiency ensures smooth, precise operation —all backed by Caterpillar’s proven electro-hydraulic system.

Machine Setup Simplification

    
• At the touch of fingertips and navigating user-friendly icons, the latest operator-oriented User Interface (UI) maximizes uptime and gets crews to work without delay. From re-ordering work tool lists to creating new work tool combinations as needed, operators can quickly set up machines and easily access information.
    
• The interface allows operators to maintain accuracy and makes the most of every second of their shift. Adding the ability to input couplers and attachments into the system makes setting up work tool combinations highly efficient by significantly reducing calibration time. It also eliminates the need to measure up again when changing Cat® work tool attachments and makes it manageable for a single person to check and adjust for bucket wear.

Cat® Grade 3D Ready

    
• The Cat Grade 3D Ready option includes all the hardware required for the Grade with 3D system, installed and tested from the factory. This option provides an easier upgrade path for customers who want to add Grade with 3D after their initial purchase. To activate, contact your Cat Dealer to purchase the required 3D software licenses. Licenses can be installed remotely or manually loaded onto the machine.

Cat Payload and Advanced Payload**

    
• Cat Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Advanced Payload is a system upgrade that offers expanded features and capabilities, including custom tags, daily totals, and electronic ticketing. Combine Payload with VisionLink® Productivity*** to analyze jobsites and individual assets for remote management of production targets and key metrics.

*Available in North America and Europe only.
**Payload technologies are not legal for trade.
***VisionLink subscription required. 

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area.
