The Komatsu PC340 Final Drive is a high-performance crawler excavator built for heavy-duty construction, mining, quarry, demolition, and large-scale earthmoving applications across Australia. Designed to deliver exceptional hydraulic power, durability, and efficiency, the Komatsu PC340 Final Drive is well suited for demanding job sites that require reliable and continuous performance.
This excavator series is available in several configurations, including the PC340LC and PC340NLC variants. Depending on the machine setup and attachments, the operating weight typically ranges from approximately 34 to 37 tonnes. The Komatsu PC340 offers strong digging capability, smooth swing performance, and reliable travel operation, making it an ideal machine for high-production excavation and material handling tasks.
Crawler excavators such as the Komatsu PC340 Final Drive rely heavily on their final drives and travel motors for machine movement, torque transfer, and overall operational efficiency. Over time, components including floating seals, planetary gears, bearings, and hydraulic motors may wear due to continuous heavy workloads, contaminated oil, and harsh working environments.
