The Caterpillar 325 crawler excavator is a compact-radius model with an operating weight of 49,604 pounds with 24-inch grouser shoes (63,493 pounds with 31-inch shoes). A 172-horsepower Cat C4.4 engine reduces fuel consumption in the Caterpillar excavator by 25 percent compared to the F Series version. It has three selectable power modes.
Maximum dig depth is 22 feet, and maximum loading height is 25 feet 1 inch. Two counterweights are available: 8.3-ton for lifting performance, and 4.9-ton for meeting transportation limitations.
Operators can program and store joystick and power mode settings using an operator ID.
The advanced hydraulic system balances power and efficiency while giving the operator complete control of excavating precision. Working on slopes is made easier with 10 percent improved swing torque. Smart mode offers an additional 5 percent fuel savings without productivity loss by automatically adjusting engine speed and hydraulic power to digging conditions.
Smartboom, an option on the Caterpillar excavator, allows the boom to travel up and down freely without using pump flow, reducing operator stress and fuel consumption. Cat Advansys bucket tips can be changed quickly with a simple lug wrench instead of a hammer or special tool, and auxiliary hydraulic options allow the use of a range of attachments.
Cat Grade with 2D machine control allows operators to program up to four target depth and slope offsets, and the system can be upgraded to Cat Grade with Advanced 2D or 3D. Other technology added to the excavator include Grade Assist, Bucket Assist, Swing Assist, Boom Assist, Lift Assist, and Cat Payload.
Three all-new cab designs are available: Comfort, Deluxe, and Premium. The ISO-certified ROPS cab is sound suppressed and sealed and features automatic climate control, protecting the operator as much as possible from the fatigue, stresses, sounds, and temperatures of rugged and challenging job conditions.
Visibility has been improved with rear and sideview cameras, and lower front profile; a 360-degree visibility feature is optional.
Maintenance costs can be reduced by up to 20 percent compared to the 325F due to extended and more synchronized maintenance intervals. All maintenance checkpoints are accessible at ground level for the Caterpillar excavator, and operators can monitor filter life and maintenance intervals via the in-cab monitor.
Consolidated filter locations reduce service time while hydraulic, air, and fuel tank filters have increased capacity and longer life. The new excavator also features an advanced air filter with double the dust-holding capacity of the previous filter.
