Features
48‑ton class heavy‑duty long‑track crawler excavator built for quarry production, heavy construction, mass earthmoving and demolition jobs. Powered by Komatsu SAA6D125E‑6 / E‑7 six‑cylinder turbo diesel engine delivering 268 kW net power at 1900 rpm. Matched modern emission after‑treatment with DPF and SCR, auto‑idle shutdown function cuts unnecessary fuel burn during site standby time.
Reinforced heavy‑duty LC long‑undercarriage design, robust X‑shaped main frame and nine track rollers per side. Larger counter‑weight brings improved lateral stability and lifting capacity. Extended track‑ground contact lowers ground pressure, performs reliably on muddy sites and quarry floors, good transportability for a machine of this weight class.
Proven Komatsu CLSS closed‑center load‑sensing hydraulic system, large‑displacement twin variable pumps deliver high flow at lower engine rpm. Multiple selectable working modes including power, economy, lifting and breaker mode. Enhanced power mode can boost overall productivity up to 13 %. Delivers fast cycle times, smooth compound movements and precise fine control. Factory‑fitted bi‑directional auxiliary lines work directly with large breakers and heavy attachments without on‑site re‑plumbing.
Boom and arm adopt high‑tensile thick steel plates and integrated cast components for anti‑twist performance. Bucket capacity ranges from 1.45 m³ up to 3.5 m³. Quarry‑rock bucket option with wear‑resistant teeth extends service‑life in abrasive rock conditions. Standard front for high‑volume truck loading, long‑arm variant available for deep‑excavation tasks. Well‑suited for quarry loading, overburden removal, highway construction, large‑scale backfill and heavy‑demolition works.
ROPS/FOPS certified spacious SpaceCab with viscous vibration‑damping mounts. Heated air‑suspension reclining seat reduces operator fatigue for long‑hour shifts. Large colour TFT monitor displays engine data, real‑time fuel consumption and fault diagnostic codes. Standard KOMTRAX telematics supports remote fleet monitoring, location tracking and maintenance reminders. Rear‑view camera optional for better jobsite safety.
Key daily service points are arranged at ground‑level height. One‑man service access for engine oil, filters and hydraulic‑oil inspection, no climbing onto upper structures. Integrated filter layout simplifies routine maintenance and reduces unplanned downtime for heavy‑cycle job‑sites.
