The 325F is a compact radius excavator built for all confined area work.
The machine uses a C4.4 ACERT Tier 4 Final engine. It will use up to 22 percent less diesel than its predecessor, with no loss of swing torque and bucket and stick forces. It has a maximum lifting capacity of 27, 000 pounds (12 650 kg) at 15 feet (4.6 m) over the front at ground level, exceeding the previous model’s capacity by 8 percent. Boom and stick recirculation valves reduce fuel consumption and cycle times. A choice of three power modes—high power, standard, and eco—help operators actively manage fuel consumption. A variable-speed fan results in less energy consumption and noise, high-ambient cooling capability to work in extreme heat, and altitude capability up to 9,840 feet (3000 m) with no engine de-rating round out the machine’s high-performance attributes.
The 325F’s compact radius design makes it suitable for work in forestry applications where space is limited. It has a front swing radius of 7’8” (2.34 m) and a tail swing radius of 5’8” (1.72 m). The machine can dig, swing, and dump within a working space of 13’4” (4.06 m). When rotated 90 degrees and working over the side, just 135 mm (5”) of counterweight extends beyond the track width. Bucket linkage is the same as the 321D, which means one can work with the same tools. The new model also includes quick coupler lines and circuit compatible with the new Cat Pin Grabber coupler. Using this coupler allows quick attachment changes from the safety of the cab and increases job site flexibility.
Other areas of notable improvements can be found in the cab (reduced sound and vibration, improved seating and controls, larger LCD monitor), areas of serviceability (ground level access and wide service doors, ports grouped together for convenience), durability (a modified robotically welded X-frame for strength), safety (handrails, anti-skid plates, increased vision from cab, review camera system, fire wall between pump and engine closures) and attachment solutions.
