Informazioni su · Hitachi ZX490Panoramica
The Hitachi ZX490 is a large hydraulic crawler excavator in the 50-tonne operating-weight class, with an operating weight of 49,398 kg and an engine output of 362 hp. It is equipped with a 2.1 m³ bucket, placing it firmly in the heavy production segment of the excavator market. Machines of this class are engineered for high-volume earthmoving, quarrying, and civil infrastructure work where cycle times and payload efficiency are primary considerations.
Applicazioni tipicheDove viene utilizzata questa macchina
The ZX490 is suited to large-scale cut-and-fill operations, open-cast mining bench work, bulk quarry extraction, and major civil infrastructure projects such as highway construction and dam or reservoir earthworks. At this operating weight and bucket capacity, the machine is typically paired with rigid or articulated trucks in the 30-to-40-tonne payload range to form an efficient loading fleet. Secondary applications include heavy demolition and large-scale land reclamation where the reach and breakout force of a 50-tonne class excavator are required.
Ispezione del mercato dell'usatoCosa controllare prima dell'acquisto
When inspecting a used ZX490 or any machine in the 50-tonne crawler class, prioritise a full undercarriage assessment, as track components represent a significant portion of reconditioning expenditure on heavy excavators. Check wear on sprockets, track shoes, rollers, and idlers, and request any available undercarriage inspection reports. Review the hydraulic system for cylinder seal condition, hose integrity, and any evidence of contamination in the hydraulic oil. Inspect the boom, arm, and bucket pins and bushings for wear and play. Verify that the engine hours displayed on the instrument cluster are consistent with the service records, and review the history for major component replacements such as engine overhaul or hydraulic pump work. Confirm that any attachments included with the machine are correctly matched to the hydraulic flow and pressure specifications of the ZX490. A pre-purchase inspection by a certified Hitachi or independent heavy-equipment technician is advisable before committing to any machine at this operating weight class.
Mercato attualePosizionamento di prezzo
The Hitachi ZX490 competes directly with the Hyundai R520 and the Kobelco SK500 in the 50-tonne crawler excavator segment. The Hyundai R520 is positioned as a volume alternative in this class, while the Kobelco SK500 carries a reputation for hydraulic efficiency and fuel economy. The ZX490 is differentiated by its 49,398 kg operating weight and 362 hp power rating, which buyers can compare against published specifications for both competitor models when assessing fleet compatibility and parts-supply considerations. Within the used market, the primary attributes that move a machine within its price band are recorded service hours, maintenance history, configuration, the presence of factory-fitted or third-party attachments, undercarriage condition, and overall cosmetic and mechanical condition. Machines with documented dealer servicing, lower hours, and matched attachments such as a genuine Hitachi bucket command stronger positioning than equivalent-hour examples with deferred maintenance or non-standard fitments.
