Aplicaciones típicasDónde se utiliza esta máquina
Excavators in the 14-tonne class are commonly deployed on utility trenching, road construction, drainage works, and site preparation tasks. The 0.57 m3 bucket capacity supports steady cycle times in medium-density materials such as clay, gravel, and mixed soils. This size class is also frequently used in landscaping, foundation excavation, and pipeline installation where a balance between reach and manoeuvrability is required.
Inspección del mercado de segunda manoQué hay que comprobar antes de comprar
When inspecting a used DX140 or any machine in this class, priority checks should include undercarriage wear on tracks, rollers, and sprockets, as these components represent a significant portion of refurbishment cost. The boom, arm, and bucket pins and bushings should be assessed for play and wear. Hydraulic hoses and cylinder seals should be inspected for leaks or chafing, particularly around the bucket and tilt circuits if auxiliary lines are fitted. Engine condition should be evaluated through oil analysis records where available, and exhaust smoke at start-up and under load is a useful indicator of internal wear. Buyers should request full service history and verify that scheduled maintenance intervals have been observed. For machines with a quick coupler, the locking mechanism should be tested and certified documentation reviewed. Structural cracks around the upper carriage slew ring and boom foot are common inspection points in this weight class and should be examined carefully before purchase.

The DX140 competes directly with the Takeuchi TB1140 and the JCB JS130 in the 13- to 15-tonne crawler excavator segment. Against the JCB JS130, the DX140 carries a higher operating weight at 14,200 kg, which can indicate greater structural robustness and stability on demanding terrain. The Takeuchi TB1140 is a comparable weight-class machine with a strong reputation for reliability in rental fleets, making configuration and condition the primary differentiators when cross-shopping. Within the segment, the attributes that drive position within the price band include accumulated machine hours, undercarriage condition, the presence of a quick coupler or auxiliary hydraulics, attachment history, and overall service documentation. Machines with low hours, full service records, and factory-fitted auxiliary lines command stronger positioning than high-hour units with worn undercarriages or incomplete histories.
