Features
78.8‑84.7‑ton large‑frame quarry‑grade crawler excavator built for high‑volume rock loading, overburden removal and heavy mass‑earthmoving projects. Powered by Komatsu SAA6D140E‑5 six‑cylinder turbo diesel engine delivering 363 kW net power at 1800 rpm. Integrated engine‑hydraulic tuning balances brute digging power and real‑world fuel efficiency for long‑duration site production.
Heavy‑duty LC long‑track undercarriage with reinforced box‑section track frame, nine track rollers per side and hydraulic track adjusters. Extended track‑ground contact area lowers ground pressure for stable operation on quarry floors and soft ground. Built‑in Heavy‑Lift mode adds 10 % extra lifting capacity for handling large rock blocks and heavy attachments.
EOLSS Electronic Open‑Center Load‑Sensing hydraulic system with twin large‑displacement variable piston pumps. Operators toggle boom‑priority or swing‑priority modes on‑screen for truck‑loading or digging cycles. One‑touch PowerMax delivers short‑term digging‑force boost, while shockless boom control suppresses vibration. Smooth combined movements and fine metered control for rock excavation and heavy‑breaker work. Factory‑routed auxiliary piping supports large breakers and quarry attachments without field modification.
Bucket range spans 2.8 m³ up to 6.91 m³. Optional quarry‑spec rock buckets use KVX high‑hardness material and long‑life KMAX teeth for extended service life in abrasive rock conditions. Standard arm optimized for high‑tonnage truck loading, long‑arm variant available for deep excavation. Well‑suited for quarry rock handling, overburden stripping, large‑scale demolition and deep foundation jobs.
ROPS/FOPS certified pressurized SpaceCab with viscous‑damper mounting to cut cabin vibration. Air‑suspension high‑back seat plus automatic air‑conditioning ease operator fatigue during multi‑hour shifts. 7‑inch colour TFT monitor displays engine metrics, live fuel consumption and fault diagnostics. KOMTRAX telematics standard for remote fleet tracking, fuel‑use analysis and scheduled‑service reminders.
Major daily service check‑points are grouped for ground‑level access. Service technicians perform engine‑oil, filter and hydraulic‑oil inspections without climbing high machine structures. High‑pressure inline hydraulic filters plus fuel pre‑filter with water‑separator protect core components from contaminated fluids, reducing unplanned downtime in remote quarry sites.
