About · Doosan DX340Overview
The Doosan DX340 is a large crawler excavator in the 34-tonne operating class, producing 247 hp and equipped with a 1.53 m³ bucket capacity. It occupies the upper-mid segment of the heavy excavator market, positioned between mid-range production machines and true heavy-duty mining-class equipment. Its combination of operating weight and engine output makes it suited to demanding earthmoving and civil engineering tasks where high productivity per cycle is required.
Typical applicationsWhere this machine is used
Machines in this weight and power class are deployed on large-scale earthmoving, bulk excavation, road construction, quarry stripping, and heavy civil infrastructure projects. The 1.53 m³ bucket capacity supports high-volume material handling where cycle efficiency and lift capacity are priorities. Contractors operating in pipeline installation, dam construction, and large site preparation regularly specify excavators in this class.
Used-market inspectionWhat to check before buying
Inspection of a 34-tonne excavator in this class should prioritise a full undercarriage assessment, as track components, rollers, and sprockets represent a significant portion of ownership cost at this operating weight. The hydraulic system warrants close attention, including cylinder seals, main pump output, and the condition of all lines and couplings. Engine hours should be verified against service records, and buyers should confirm that scheduled maintenance intervals, particularly for the engine and final drives, have been observed. Structural inspection of the boom, arm, and attachment points for cracks or weld repairs is essential given the load cycles typical of this class. Requesting a live working demonstration and a fluid analysis report before purchase is standard practice for machines at this weight.
Current marketPrice position
The DX340 is routinely cross-shopped against the Liebherr R936 and the Hyundai R340, all three operating in the 34-tonne class with comparable power and bucket sizing. The Liebherr R936 is generally associated with a premium engineering reputation and strong residual retention, which can position it differently within the band despite similar specifications. The Hyundai R340 competes closely on performance figures and is frequently evaluated on parts availability and support network reach. Within the DX340's own pricing band, the primary factors that move a unit are accumulated hours, overall mechanical condition, attachment configuration, boom and arm specification, and the presence of additional hydraulic lines or quick-coupler systems. Machines with low hours, well-documented service histories, and purpose-matched attachment packages command the stronger positions within the range.
