New heavy-duty undercarriage configuration for the CatŪ 325 excavator
Delivering powerful performance, the Cat® 325 excavator features easy-to-use standard technology like Cat Grade with 2D, Grade Assist, Lift Assist and Payload to help boost productivity by allowing operators to work accurately, efficiently and quickly. Long heavy-duty undercarriage with oversized 203-mm (8-in) track pitch delivers outstanding stability and durability in harsh, uneven ground conditions, including site preparation, land clearing and forestry. Equipping the 325 with the optional blade simplifies backfilling and helps keep the machine levelled when working on slopes.
Featuring a 7.5-tonne (16,540-lb) counterweight, the new configuration enhances balance and control even when equipped with attachments like a blade, Variable Angle Boom (VAB), heavy-duty stick, bucket thumbs, or quick coupler. The new configuration can be fitted with either Reach or VAB fronts, with or without a blade, and comes with a thumb-ready stick and quick coupler circuit preinstalled from the factory, reducing the need for aftermarket modifications. Stability equivalent to the 325 with an 8.3-tonne (18,300-lb) counterweight and standard undercarriage, its larger final drives increase drawbar pull to better climb grades, and higher swing torque maintains swing uphill capabilities.
“We are excited to launch the new 325 configuration. Designed with our customers in mind, it supports heavier work tool combinations while delivering enhanced stability. The extended undercarriage and dedicated counterweight contribute to a solid, balanced platform, while increased drawbar pull and swing torque help improve performance on challenging terrain and slopes,” said Adrian Grigorita, Vice President, Product Management for Medium Hydraulic Excavators, Caterpillar.
When equipped with the latest HD configuration, the compact radius Cat 325 excavator delivers heavy-duty performance with unmatched versatility when working in tight spaces. It offers all the benefits expected by operators – factory-integrated technology to boost productivity, extended maintenance intervals to help keep operating costs low, and electrohydraulic efficiency for smooth, precise operation.
The excavator’s electro-hydraulic pump and main control valve work together to optimize power and efficiency for the 325, delivering the performance needed. By automatically adjusting engine power to match hydraulic demands, Smart Mode operation helps lower fuel consumption.
Longer fuel life, hydraulic oil and air filters for the 325 reduce the number of filters over the life of the machine to deliver low maintenance costs. No pilot or case drain filters result in fewer filters to replace over the machine’s service life, and ground-level engine oil level checks keep the operator safely on the ground when performing daily maintenance inspections.
