Caterpillar’s versatile, short tailswing excavator

178 Caterpillar claims that its new 25tonne compact radius excavator offers increased performance and capabilities over the firm’s earlier model in this class.

The 325F is powered by a Cat C4.4 ACERT engine rated at 120kW and which meets the Tier 4 Final/Stage IV emissions requirements while the excavator also benefits from an upgraded hydraulic system. The machine has a full-size, ROPS-equipped cab said to offer safety and comfort, as well as good all-round visibility. The machine is available with technology

options such as the Cat Grade Control and AccuGrade packages that help boost productivity. Heavy-duty in construction, the machine also is offered with a choice of booms and a wide selection of quick couplers and work tools to broaden its versatility.

The machine’s aftertreatment system requires no action from the operator and does not interrupt working. The machine also has an engine-speed control system that lowers rpm to optimum for the application, saving fuel as well as an automatic engine-idle shutdown system and three power modes. The machine can operate at altitudes of up to 3,000m with no power loss and the engine can run on B20 biodiesel, while it also has a cooling system that allows the 325F to work in extreme heat. Machine weight ranges from 25.3-25.9tonnes, depending on specification.

For long-term durability, the 325F uses a modified X-frame design, as well as a heavy-duty undercarriage. Compared to the earlier 321D L CR model, the 325F offers the same productivity as well as increased lifting capacities (up to 7% over-the-front, and up to 9% over-the-side), and a 12% improvement in fuel consumption. The 325F has been designed with accessible serviceability in mind, and most routine maintenance points are available at ground level.
