Informacje · Caterpillar 345Przegląd
The Caterpillar 345 is a large hydraulic excavator operating in the 45-tonne class, with a working weight of 44,953 kg and an engine output of 345 hp. Equipped with a bucket capacity of 1.9 m3, it is positioned among the upper tier of production excavators suited to high-volume earthmoving and heavy civil work. The model has been in continuous production since 1994, giving it one of the longer service histories in its class and a correspondingly broad parts and support network.
Typowe zastosowaniaGdzie ta maszyna jest używana
The 345 is sized for large-scale excavation, bulk material handling, and major infrastructure projects where high cycle rates and deep-reach capability are required. Typical deployments include quarry face work, highway and dam construction, port and harbour development, and large open-cut earthmoving. Its bucket capacity and operating weight also make it a common choice for loading rigid-frame haul trucks in high-production mining support roles.

Inspection of a used 345 should begin with a thorough undercarriage assessment, as the undercarriage represents a significant share of lifecycle cost on any machine in this weight class. Buyers should check track shoe wear, roller and idler condition, and sprocket profile before considering any other factors. The hydraulic system warrants close attention, including cylinder seal condition, hose integrity, and pump performance under load, given the high working pressures typical of a machine producing 345 hp. Structural inspection of the boom, arm, and slew ring for cracks, weld repairs, or abnormal wear patterns is standard practice for machines in this class. Service records should be reviewed to confirm oil analysis history and scheduled component replacements. Configuration details, including boom length, bucket size, and any auxiliary hydraulic circuits, should be verified against the intended application before purchase, as retrofitting non-factory configurations can affect both performance and residual value.

Within the 40-to-50-tonne excavator class, the Caterpillar 345 is cross-shopped most frequently against the Doosan DX420 and the Hyundai R430. The Doosan DX420 sits slightly above the 345 in operating weight, which can be relevant on projects with higher ground-bearing-pressure constraints or where maximum digging force is prioritised. The Hyundai R430 also exceeds the 345 in machine weight class, giving buyers a direct comparison point for those requiring additional ballast or reach. Where the 345 differentiates itself is through the depth of the Caterpillar dealer and parts infrastructure and the long production continuity since 1994, which supports component availability across multiple machine generations. Within the 345 segment itself, the attributes that move a unit within its price band are accumulated service hours, configuration type (long undercarriage, mass excavator, or standard boom), the presence of factory-fitted or third-party attachments, documented service history, and overall mechanical and structural condition.
