Over · Doosan DX300Overzicht
The Doosan DX300 is a 30-tonne class crawler excavator produced continuously from 2007 to the present day. It is rated at 197 hp and carries a bucket capacity of 1.15 m3, positioning it firmly in the upper-mid range of the heavy excavator segment. Its operating weight of 29,300 kg places it alongside other machines in the 29 to 31-tonne bracket, a class widely used across civil engineering, quarrying, and infrastructure applications.
Typische toepassingenWaar deze machine wordt gebruikt
Machines in the 30-tonne excavator class are routinely deployed on bulk earthmoving, trench excavation, and foundation work where a balance of reach, breakout force, and site mobility is required. The DX300 is also used in demolition support roles and heavy material handling, particularly where a 1.15 m3 bucket capacity suits large-volume dig cycles. Quarrying, road construction, and pipeline projects represent further typical fields of deployment for this machine class.
Tweedehandsmarkt inspectieWat je moet controleren voordat je koopt
Inspection of the undercarriage is the priority on any 30-tonne crawler excavator, as track wear, sprocket condition, and roller integrity represent the most significant cost exposure on a used machine in this class. Buyers should request a full service history and verify that scheduled maintenance intervals have been observed, paying particular attention to hydraulic system condition including hose integrity, pump response, and any evidence of seal leakage at the arm and bucket cylinders. Structural inspection of the boom, dipper, and upper frame for cracks or repair welds is standard practice in this class. Machines that have operated in abrasive or demolition environments should be assessed carefully for accelerated wear on the slew ring and swing motor. Confirming that all auxiliary hydraulic circuits function correctly is especially important where attachments have been fitted, as improper installation can cause downstream hydraulic damage.
Huidige marktPrijspositie
The DX300 competes directly with the Hyundai R290 and the Hitachi ZX300, and buyers regularly cross-shop all three when sourcing in this weight class. The Doosan sits at 29,300 kg operating weight and 197 hp, which is comparable to those competitors, meaning differentiation between units in the market is driven primarily by configuration, recorded working hours, attachment inventory, and overall physical condition rather than fundamental specification gaps. Within any group of DX300 units, machines configured with additional hydraulic lines, quick couplers, or specialist buckets will command a stronger position in the price band relative to base-spec examples. Hour accumulation is the single most consistent driver of spread within this class, with servicing history and undercarriage condition being the key secondary factors. The Hitachi ZX300 is generally regarded as carrying strong residual values in this segment, providing a useful reference point when assessing relative positioning, while the Hyundai R290 offers a close weight and power comparison to the Doosan.
