About · Komatsu PC78Overview
The Komatsu PC78 is a midi-excavator occupying the upper tier of the compact excavator class, offering a working weight and digging performance that bridges the gap between conventional mini-excavators and full-size short-radius machines. It is designed to deliver productive digging, trenching, and lifting capacity while remaining compact enough for restricted-access urban and suburban worksites. Komatsu's build quality and parts network make the PC78 a recognised option in the European contractor market.
Typical applicationsWhere this machine is used
Machines in this class are well suited to foundation work, utility trenching, landscaping, and drainage projects where ground conditions and site access limit the deployment of larger equipment. The PC78's size also makes it practical for road and kerb work, pipe laying, and light demolition in confined environments. Contractors frequently use midi-excavators of this type as versatile single-machine solutions on small to medium civil engineering projects.
Used-market inspectionWhat to check before buying
Prospective buyers should commission a full inspection of the undercarriage, including track pads, rollers, and sprockets, as these components represent a significant portion of lifecycle costs on any tracked excavator. The hydraulic system, boom and arm pins, and bucket linkage should be checked for wear, oil leaks, and play. Service history documentation, including filter and fluid change records, is an important indicator of maintenance discipline. A pre-purchase inspection by a qualified Komatsu technician or an independent engineer is advisable to verify the machine's condition before committing to purchase.
Current marketPrice position
In the European market the PC78 is positioned at an average transaction level of EUR 23,500, reflecting demand for capable midi-excavators from contractors seeking a balance between compact dimensions and productive output. Buyers comparing options in this segment should evaluate the PC78 alongside competing midi-excavators from manufacturers such as Caterpillar, Volvo, Hitachi, and Doosan, assessing total cost of ownership, dealer support density, and parts availability in their region.
