Technical Description

The Hyundai ROBEX 235LCR-9 is a mid-sized tracked excavator engineered for versatile construction and earthmoving applications. Powered by a Cummins QSB6.7 diesel engine, this machine delivers robust performance with 129-136 kW (173-185 HP) of net power at 1,950 rpm and maximum torque of 81.6 kgf (590 lbf-ft) at 1,500 rpm. The engine features a 6.7-liter displacement with a 107 × 124 mm bore and stroke configuration, incorporating high-pressure common-rail fuel injection technology for efficient combustion and reduced emissions. Operating at an all-up weight of 53,830 lbs (approximately 24,400 kg), the excavator maintains excellent stability and maneuverability on jobsites. The unit features a maximum digging depth of 22 feet and maximum reach along ground of 32.5 feet, making it suitable for moderate-scale excavation tasks. The machine is equipped with a variable displacement tandem-axis piston pump hydraulic system delivering 2 × 222 liters per minute (58.6 US gpm), enabling smooth operation of all hydraulic functions including boom, arm, bucket, travel, and swing systems. The tracked chassis design provides superior traction and ground pressure distribution compared to wheeled alternatives, allowing operation on challenging terrain. Standard features include a two-speed travel motor with brake valve and parking brake, swing motor with automatic brake, and multi-channel relief valve protection. The ROBEX 235LCR-9 represents a reliable, fuel-efficient platform capable of handling demanding excavation, material handling, and site preparation work across multiple industries.
