With an operating-weight range of 11,330 and 12,750 pounds, the compact Komatsu PC55MR hydraulic excavator uses a Tier 4-Final, 38-horsepower Komatsu SAA4D88E-7 engine. Equipped with a swing-type boom, the new model has a maximum digging depth of 12.5 feet and a maximum reach of 19 feet 11 inches. The standard auxiliary-hydraulic system produces a flow of 18.5 gpm and can be switched between single- and bi-directional flow as application requires. Cab appointments include a suspension-type, high-back seat and a new high-resolution, 3.5-inch LCD monitor with enhanced capabilities.
