Compact Size for Restricted Work Areas

The Komatsu PC56 measures 5,935 mm long, 1,960 mm wide, and 2,550 mm high. This compact profile makes transport and site access easier than with a larger crawler excavator.

Moreover, the machine can work close to buildings, walls, road edges, and existing landscaping. It is therefore useful for renovation projects, utility maintenance, residential foundations, and small commercial sites.

Its front dozer blade can also support ground leveling, trench backfilling, and machine stabilization.

Reliable Engine and Hydraulic System

The Komatsu S4D87E-1 engine has four cylinders and a displacement of 2.434 L. Its water-cooled design helps maintain a stable working temperature during regular operating shifts.

Meanwhile, the Komatsu hydraulic pump and distribution valve provide controlled movement for the boom, stick, bucket, and upper structure. The machine offers 39.8 kN of bucket digging force and 24.4 kN of stick digging force. Therefore, it can handle soil, clay, sand, gravel, and similar materials.

Practical Digging and Loading Range

The maximum digging depth reaches 3,810 mm, while the maximum digging radius is 6,130 mm. In addition, the PC56 provides a maximum digging height of 5,860 mm and an unloading height of 4,130 mm.

This working range is suitable for opening utility trenches, preparing foundations, cleaning drainage channels, loading small trucks, and completing landscaping work. Its 9 rpm swing speed also supports efficient work cycles in confined areas.
