Informazioni su · Doosan DX205Panoramica
The Doosan DX205 is a 20-tonne class crawler excavator positioned in the mid-size segment, a category that balances digging reach and lifting capacity with jobsite versatility. It is powered by a Doosan diesel engine meeting current emissions requirements and operates with a hydraulic system calibrated for both productive cycle times and fuel efficiency. At approximately 20 tonnes operating weight, the machine sits between compact utility excavators and the heavier construction-grade equipment used on large civil projects.
Applicazioni tipicheDove viene utilizzata questa macchina
Mid-size crawler excavators in the 20-tonne class are routinely deployed on groundworks, road construction, utility trenching, building demolition, and land clearing. Their combination of arm reach, bucket capacity, and ground bearing pressure makes them suitable for both confined urban sites and open civil engineering projects. The class is also commonly used for bulk earthmoving on medium-scale infrastructure contracts where a compact machine would be underpowered and a larger unit operationally impractical.
Ispezione del mercato dell'usatoCosa controllare prima dell'acquisto
Before purchasing any 20-tonne class crawler excavator, commission a full hydraulic pressure and flow test to verify that main pump output and auxiliary circuits perform to specification. Inspect the undercarriage thoroughly, including track pad thickness, sprocket and idler wear, and roller condition, as undercarriage rebuilds represent a significant cost category in this machine class. Check for any structural cracking at the boom foot pins, dipper arm, and chassis tail, particularly on machines with documented demolition or rock-breaking use. Review the service history for evidence of scheduled filter and fluid changes, and confirm that any emissions-related components such as the diesel particulate filter or exhaust treatment system are serviceable. Operational checks should include swing bearing play, travel motor response under load, and boom and arm cylinder seal condition.
Mercato attualePosizionamento di prezzo
The DX205 competes directly with the Hitachi ZX200 and the Hyundai HX360 when buyers are evaluating mid-range crawler excavators. The Hitachi ZX200 is a long-established reference point in the class, widely regarded for hydraulic refinement and parts availability, which gives it strong buyer familiarity. The Hyundai HX360 sits in a heavier weight class and offers greater reach and lift capacity, meaning cross-shopping between the DX205 and the HX360 typically reflects a buyer reconsidering their actual payload and reach requirements rather than a direct like-for-like comparison. Within the DX205 segment, the attributes that move a unit within its price band are accumulated hours, service and maintenance history, configuration choices such as long-reach or standard boom, the presence of a quick-coupler or other attachments, undercarriage condition, and overall mechanical and structural condition. Machines with lower hours, full service records, and well-maintained undercarriages command stronger positions in the band; high-hour units or those requiring undercarriage work trade accordingly.
