Technical Description
The Hyundai Robex 140LC-9 is a versatile medium-sized hydraulic excavator designed for efficient earthmoving and construction tasks. Powered by a Mitsubishi D04FD-TAA 4-cylinder, turbocharged, water-cooled diesel engine delivering 114 hp (85 kW) net power, this machine balances power, reliability, and fuel economy effectively. It has an operating weight of approximately 30,820 lbs (13,980 kg), ensuring stability and robust performance on various terrains. The excavator features a boom length of 4600 mm and stick options up to 2500 mm, providing a maximum digging depth of 20 feet (approximately 6 meters) and a maximum reach along the ground of 28.8 feet (about 8.8 meters), suitable for deep trenching and wide excavation work.
The hydraulic system incorporates advanced features such as the CAPO system for power optimization, hydraulic flow summation, regeneration system, and a Power Boost function that temporarily increases digging forces by 10% for demanding tasks. The swing system boasts enhanced flow priority for improved cycle times and excellent maneuverability, with a maximum travel speed of about 5.5 km/h. Operator comfort is prioritized through a spacious cabin with enhanced visibility, fully adjustable seat, advanced air-conditioning system with multiple air ducts, and user-friendly electro-hydraulic controls ensuring fast response and precision.
Fuel efficiency is addressed via auto-deceleration, one-touch idle, and dedicated breaker mode functions that optimize engine and hydraulic pump operation according to demand, reducing consumption during idle and light work conditions. The instrument panel provides comprehensive operational data, including hydraulic oil temperature, fuel level, and engine parameters, facilitating maintenance and diagnostics. The excavator is equipped with a reliable axial piston motor drive, hydrostatic travel, and planetary reduction gearing for durable performance under heavy loads. Overall, the Hyundai Robex 140LC-9 is engineered to deliver high productivity, fuel economy, and operator convenience in a compact, durable package.
