KOMATSU H655S CRAWLER EXCAVATOR

Technical Description

The Komatsu H655S is a large-scale hydraulic excavator engineered for demanding mining and heavy construction applications. This super-size equipment weighs 1,510,167 pounds (685,000 kg) and operates on a powerful turbocharged 16-cylinder Caterpillar 3516 engine delivering 3,714 net horsepower at 1,800 rpm. The machine features an impressive 43.2 cubic yard bucket capacity, accommodating substantial material volumes in single passes. Dimensionally, the H655S measures 25.6 feet in width across its tracks and stands 31.12 feet tall to the cab roof. Its maximum cutting height reaches 67.26 feet, with a digging reach of 55.12 feet along the ground, enabling operators to access difficult or elevated terrain effectively. The excavator maintains a ground clearance of 3.76 feet and operates at 35.4 psi ground pressure, distributing its substantial weight efficiently across 59.1-inch track shoes. The hydraulic system operates at 4,495 psi relief pressure with a robust 1,902.1 gallons-per-minute pump flow capacity, supported by a 2,205.9-gallon fluid reservoir. Maximum swing speed of 3.5 rpm provides controlled rotational capability for material handling operations. Tank capacity of 2,905.9 gallons ensures extended operational periods between refueling. Designed for versatility, the H655S performs digging, grading, demolition, and material handling tasks effectively. Its heavy-duty construction and precision hydraulic controls make it the optimal choice for large-scale mining operations and demanding construction projects requiring exceptional load capacity and operational reach capabilities.
