The Komatsu PC27MR-3 is a mini excavator from the Japanese manufacturer, positioned in the category of compact earthmoving machinery. This model is designed for applications where small dimensions and moderate weight are the primary considerations. The design is optimized for maximum compactness to enable operation in confined urban or landscape environments.
The machine is powered by the Komatsu 3D82AE-6 engine, which operates at a rated speed of 2,600 rpm. The empty weight of 2,890 kg ensures high stability without compromising transportability. With a width of 1,550 mm and a length of 2,520 mm, the excavator can be maneuvered through narrow access routes. The climbing ability of 30% allows it to handle slopes and uneven terrain, while the tank capacity of 44.3 l provides sufficient operating time for short to medium work cycles.
Within the mini excavator series, this model is distinguished by its specific dimensions and weight. The compact design with a height of 2,520 mm permits use in areas with low clearance heights. The combination of low self-weight and defined climbing ability makes the PC27MR-3 a suitable choice for work in gardens, cemeteries, or courtyards, where large machines cannot be deployed. The technical design focuses on handling in spatially limited scenarios.
