CATERPILLAR 325D LRE CRAWLER EXCAVATOR

Technical Description

The Caterpillar 325D LRE excavator is a robust hydraulic excavator designed for long reach applications, equipped with the Caterpillar C7 ACERT engine delivering a net power of 190 hp (142 kW). This inline 6-cylinder, 4-stroke diesel engine features turbocharged aftercooling and direct injection technology to provide reliable performance and meet emissions standards while optimizing fuel efficiency. The engine's displacement is approximately 7.2 liters, with a high compression ratio around 16.2:1, supporting durable and efficient power delivery suitable for heavy earthmoving tasks. Operationally, the 325D LRE excels with a maximum cutting height of 44.5 feet, a maximum digging depth of 37.3 feet, and a maximum reach extending to 52.46 feet, enabling access to difficult excavation sites. Its heavy-duty undercarriage and boom-stick configurations allow enhanced stability and extended reach capabilities, making it ideal for dredging, slope cutting, and other specialized excavation jobs. The machine's operating weight is approximately 29,240 kg (64,460 lb), with standard 800 mm triple grouser shoes ensuring good traction. This model includes advanced hydraulic systems with a flow rate of around 124.2 gallons per minute and pressures near 5076 psi for efficient hydraulic power transmission. The 325D LRE’s electronic engine management system (ADEM) enables precise control, diagnostics, and automatic altitude compensation to maintain performance across various environments. Its combination of power, reach, and durability makes it a versatile solution for demanding construction and mining operations requiring extended reach excavating capabilities.
