Features
78.7‑ton large long‑track crawler excavator built for quarry production, overburden removal and heavy‑duty mass‑loading work. Powered by Komatsu SAA6D140E‑5 six‑cylinder turbo diesel engine delivering 363 kW net power at 1800 rpm, matched to reliable performance for high‑output sites. Multiple selectable work modes balance breakout force and fuel burn during long production shifts.
Reinforced LC long‑undercarriage design with heavy‑duty track frame, nine track rollers each side and hydraulic track adjusters. Extended track‑to‑ground contact reduces ground pressure, delivers rock‑site stability and good flotation on soft ground. Heavy‑lift mode adds extra lifting capacity for handling large rock blocks.
Electronic Open‑Center Load‑Sensing hydraulic system (EOLSS) with dual large‑displacement variable pumps. Operators toggle boom‑priority or swing‑priority from the in‑cab monitor to suit truck‑loading or digging cycles. One‑touch Power Max gives short‑term boost for hard rock digging. Smooth combined movements and precise metered control for digging, grading and heavy breaker operation. Factory‑ready auxiliary lines support large breakers and heavy attachments.
Bucket selection ranges 3.4 m³ up to 4.3 m³; quarry‑spec rock buckets with KMAX wear‑resistant teeth extend service life in abrasive conditions. Standard arm for high‑volume truck loading, optional long arm configuration for deep excavation projects. Suited for quarry rock loading, overburden stripping, large‑scale demolition and deep foundation excavation.
Spacious ROPS/FOPS certified pressurized cab with air‑conditioning and high‑end air‑suspension seat, reducing operator fatigue during multi‑hour shifts. Full‑color EMMS display shows engine data, real‑time fuel consumption and fault diagnostics. KOMTRAX telematics fitted as standard for remote fleet tracking, location log and scheduled‑service alerts. Rear‑view monitor improves jobsite all‑round visibility.
Major daily service check‑points are grouped for ground‑level access. Technicians complete engine oil, filter and hydraulic oil inspections without climbing high structures. High‑pressure inline hydraulic filters and dual fuel filtration help protect components from poor‑quality fuel, lowering unplanned downtime in remote quarry sites.
