Technical Description

The Hyundai ROBEX 520LC-9 is a heavy-duty crawler excavator designed for demanding excavation and material handling applications. Powered by a proven Cummins Tier III QSM11 diesel engine, this machine delivers 342 net horsepower (255 kW) with electronically controlled fuel injection optimized for efficient combustion and reduced emissions. The engine features a 10.8-liter displacement with turbocharged and aftercooled aspiration, providing reliable power across variable operating conditions. Operating at an impressive 112,435 lbs (51 metric tons), the ROBEX 520LC-9 achieves a maximum digging depth of 26.9 feet and maximum reach along ground of 41.5 feet with its boom and stick configuration. The excavator features industry-leading Kawasaki-designed variable volume in-line axial piston pumps delivering optimized hydraulic performance with a new auto boom/swing priority system for enhanced productivity. Its steel cab provides 360-degree visibility with a through upper skylight, integrating an LCD display monitoring system with centralized diagnostics and GPS download capability. The machine incorporates multiple operating modes—Power, Standard, and Economy—allowing operators to optimize performance based on application requirements while maximizing fuel efficiency. Advanced features include automatic climate control, self-diagnostic systems, and a starting aid for cold weather operation. The swing system operates at 9.0 rpm with a multi-wet disc brake, while ground pressure measures 0.88 kgf/cm² with a 600mm shoe configuration. This combination of power, versatility, and operator-focused engineering makes the ROBEX 520LC-9 an excellent choice for construction, mining, and earthmoving operations.
