The PC09-1 compact hydraulic excavator from Komatsu America Corp. offers a foldable canopy and expandable undercarriage that is able to retract to pass through doorways. When expanded, the undercarriage provides additional stability when excavating. Its triple-flanged bottom track rollers aid in machine stability when traveling or excavating by maintaining at least two points of contact between the track lug and roller. The PC09-1 has an operating weight of 1,985 pounds and a dig depth of 5 feet, 6 inches when equipped with the long arm. An optional 75-foot-pound breaker arm allows operators to break through concrete without removing the bucket.
