Features
45‑ton class heavy‑duty large crawler excavator, widely applied for quarry operation, open‑pit stripping, heavy rock excavation and mass ore‑loading tasks.
Powered by Komatsu SAA6D125E‑5 six‑cylinder turbo diesel engine, net power 257 kW at 1900 rpm, strong low‑speed torque output. Tier‑3 mechanical configuration without complex urea after‑treatment, stable power output under continuous heavy‑rock workloads, affordable spare‑parts for long‑time high‑intensity jobsites.
Reinforced heavy‑duty undercarriage with double‑flange track rollers, heavy‑wear‑resistant track shoes and optional full‑length rock guard plates. Optimized heavy counterweight delivers excellent whole‑machine stability, low sinking risk on muddy mine yards during deep digging and heavy truck‑loading cycles.
Dual front‑end configurations for selection. Standard long boom for deep open‑pit overburden removal; short SE boom matched with high‑capacity rock bucket improves loading efficiency. Thickened high‑tensile‑steel boom & arm with multi‑reinforced welding ribs, long‑life fully sealed dust‑proof pins resist heavy rock impact and reduce oil‑leak failures in harsh mining environments.
CLSS closed‑center load‑sensing regenerative hydraulic system, dual variable‑displacement main pumps deliver total flow up to 690 L/min. Multiple selectable working modes: power, economy, lifting and breaker mode. Smooth simultaneous compound movements and precise fine control for rock digging, stripping and bulk‑material loading. Factory‑pre‑fitted bi‑directional auxiliary hydraulic circuit supports heavy hydraulic breakers, grapples and rippers without on‑site pipe modification.
ROPS/FOPS certified operator cab with stone‑protection guards, four‑point viscous vibration‑damping mounting and full air‑conditioning system. Low‑noise interior, colour TFT monitor clearly displays engine parameters, real‑time fuel consumption and fault diagnostic codes for convenient machine supervision.
KOMTRAX telematics system offers real‑time remote fleet monitoring, covering machine location, working hours, fuel consumption and fault‑alarm data. Supports remote fault diagnosis and scheduled‑maintenance reminders, simplifies fleet management for quarries and large construction sites.
All key daily service check‑points are arranged at ground‑level access position. Single‑operator can complete routine inspection of engine oil, filters and hydraulic oil without climbing upper structures. Reinforced chassis and front‑end assemblies extend service life under abrasive rocky conditions and minimize jobsite downtime.
