KOMATSU PC300HD-7 CRAWLER EXCAVATOR

Technical Description

The Komatsu PC300HD-7 excavator is a heavy-duty hydraulic machine optimized for both general excavation and material handling applications. Powered by a turbocharged SAA6D114E-2 engine, it delivers a net power output of 242 horsepower (180 kW) at 1900 rpm, balancing power and fuel efficiency. The hydraulic system utilizes variable displacement piston pumps with an output flow of approximately 535 liters per minute, enabling precise and powerful control of boom, arm, bucket, swing, and travel functions. The machine's operating weight is approximately 78,680 lbs, supported by a robust undercarriage featuring seven track rollers per side and 31.5-inch wide track shoes for enhanced stability and ground contact. Material handler configurations offer versatility with boom and stick options: a 2-piece 14.6 m (48 ft) front for maximum reach of 47.5 ft and lift height up to 52.5 ft, and a 3-piece 14.0 m (46 ft) front option providing a maximum reach of 45 ft and lift height of 47.5 ft. Both options support deep excavations with maximum digging depth ranging from 17 to 17.5 ft. The standard digging depth of the base machine reaches 24 ft, with a similar horizontal digging reach. Transmission is hydrostatic with two forward gears, facilitating smooth speed transitions and powerful travel performance on-site. The excavator’s design emphasizes operational efficiency and durability with enhanced lifting capacities, high bucket digging forces, and extended maintenance intervals thanks to durable SCSH bushings. This machine is ideal for demanding construction, demolition, and material handling tasks requiring extended reach and robust hydraulic power.
