Technical Description
The Komatsu HB215LC-1M0 is a robust hydraulic excavator equipped with a Komatsu SAA4D107E-1-A engine, delivering a gross power of 147.6 hp (110 kW) and net power of 139.5 hp (104 kW). This turbocharged, aftercooled, water-cooled 4-cycle direct injection engine features a bore of 4.3 inches and a stroke of 4.9 inches, providing reliable performance and efficient fuel consumption. The excavator utilizes the advanced HydrauMind hydraulic system, a closed-center configuration with load sensing and pressure compensated valves, powered by variable displacement piston pumps generating a maximum flow of approximately 439 liters per minute. Its hydraulic tank capacity is 35.7 gallons, with final drive fluid at 0.9 gallons and swing drive fluid at 1.9 gallons.
The undercarriage includes 49 track shoes per side, 9 track rollers, and 2 carrier rollers, mounted on an X-frame center section with box-section track frames for durability. The track gauge measures 7.9 feet, and the tail swing radius is 9.1 feet, enabling maneuverability in confined spaces. The service brake is a hydraulic lock, combined with a mechanical disc swing brake for controlled operation.
Operating at an approximate weight of 21,220 to 21,850 kg, the HB215LC-1M0 supports versatile jobsite demands with five selectable working modes—Power, Lifting, Breaker, Attachment, and Economy—optimizing productivity and fuel efficiency. It integrates features such as electronic closed-centre load sensing, pump and engine mutual control, and adjustable PPC wrist control for precise hydraulic operations. Travel involves an automatic 3-speed hydrostatic system with planetary gear final drives and hydraulic travel and parking brakes, supporting a gradeability of 70% (35°). The swing system operates via electric drive with planetary gear reduction and a swing speed of 12.4 rpm, delivering a swing torque of approximately 50,920 ft-lbs.
