About · Komatsu PC290Overview
The Komatsu PC290 is a purpose-built crawler excavator sitting in the 30-tonne class, with an operating weight of 32,070 kg and an engine output of 213 hp. It accepts a bucket capacity of 1.63 m3, positioning it firmly in the upper-midsize segment between compact excavators and full heavy-duty units. The model has been in continuous production since 2001, giving the platform a long service history and an established base of parts and technical knowledge. That longevity supports a consistent supply of used units across a wide range of ages and specification levels.
Typical applicationsWhere this machine is used
Machines in this weight and power class are routinely deployed on civil infrastructure work including road construction, pipeline trenching, and site preparation where ground conditions demand a heavier footprint and greater digging force than smaller units can provide. The 1.63 m3 bucket capacity suits bulk earthmoving, foundation excavation, and loading operations at medium-to-large quarry faces or construction sites. Utilities contractors and demolition operations also draw on this class when reach, breakout force, and stability under load are priorities.
Used-market inspectionWhat to check before buying
Before committing to a unit in this class, commission a full hydraulic pressure test covering the main pump circuit, swing motor, and boom and arm cylinders, as wear in these components is not visible during a walkaround inspection. Undercarriage inspection is critical at this operating weight: measure track shoe thickness, roller and idler wear, and sprocket tooth profile, since undercarriage refurbishment on a 32-tonne machine represents a significant share of reconditioning cost. Review the engine for blow-by, oil consumption, and coolant condition, and extract available telematics or service meter data to cross-check reported hours against visible wear patterns. Confirm that the boom, arm, and bucket pins show no excessive play and that all hydraulic lines are free from chafing or field repairs. For any unit fitted with a quick-coupler or auxiliary hydraulic circuit, verify that the auxiliary flow and pressure settings match the intended attachments. Structural inspection should cover the boom and arm for weld repairs or cracks at high-stress connection points, particularly on machines that have worked in demolition or rock-breaking applications.
Current marketPrice position
Within the 30-tonne crawler excavator segment the PC290 is most directly cross-shopped against the Caterpillar 329 and the Kobelco E305. The Caterpillar 329 sits in the same weight bracket and is typically evaluated alongside the PC290 on dealer network density and parts availability, while the Kobelco E305 is often compared on boom geometry and swing performance for tighter site applications. The Komatsu PC290 carries the weight of a long production run from 2001 to the present, which means the used pool spans a broad age range and the variation in condition and configuration is considerable. Within that pool, the attributes that move a unit within its price band include accumulated hours, whether the machine carries a long-reach, mass-excavation, or standard arm configuration, the presence and condition of quick-coupler systems or specialist attachments such as hydraulic thumb or tiltrotator provisions, regional service history documentation, and overall undercarriage wear state. Machines with verified scheduled maintenance records and recently replaced undercarriage components command stronger positioning relative to otherwise comparable units.
