Looking for a used Doosan DX520 for a substantial excavation or loading contract? Assess this 50-ton-class crawler excavator against your material, truck fleet and daily production requirements. Ask about current machine options in China, then compare loaded performance, structural condition and total site delivery cost before selecting a unit for your project or customer.
A used Doosan DX520 makes commercial sense when a defined project can use its size throughout the working day. Start with the material volume, truck payloads, haul cycle and planned working hours. Establish whether excavation or loading capacity actually limits output. If trucks arrive too slowly or material preparation holds up loading, a larger excavator alone will not increase completed production. Assess the selected machine within the whole operation.
Consider this class for substantial bulk earthworks, overburden excavation and loading suitable prepared quarry material. Match the fitted bucket and front equipment to material density, loading height and the excavation profile. Mine or quarry use requires a site-specific assessment; the model name does not establish suitability for every rock condition.
Anhui Gangya Construction Machinery Sales Co., Ltd., based in Hefei, China, welcomes inquiries from machinery dealers, brokers, trading companies and project contractors. Ask for current DX520 options with the full machine designation, included equipment and preparation scope recorded against each offer.
For resale, establish the end customer’s project and budget before committing to stock. Include ocean freight, destination handling, site delivery and foreseeable preparation in the purchase calculation. Confirm that fuel supply, an experienced operator and maintenance support are available where the machine will work.
Use the complete factory designation and production information to select the correct technical data. A DX520LC brochure cannot establish the specification of every machine advertised as DX520.
| Item | Details |
| Model | Doosan DX520; full plate designation and version to be confirmed |
| Machine type | Crawler hydraulic excavator |
| Size class | 50-ton class; exact operating weight depends on configuration |
| Operating weight | Confirm for the fitted front equipment, bucket, tracks and counterweight |
| Engine and rated power | Verify engine identification and the applicable factory rating |
| Bucket | Record capacity, bucket weight, construction and intended material |
| Boom and arm | Confirm fitted lengths, working range and compatible bucket selection |
| Undercarriage | Record track shoe width, track configuration and overall width |
| Shipping dimensions | Measure the agreed transport configuration and identify separate loads |
Working weight and shipping weight serve different purposes. Base freight calculations on the actual shipping arrangement, with dimensions and weights confirmed for every separate load.
Production loading matched to the truck fleet
For a contractor with substantial material to move, a DX520 is a candidate for a dedicated excavation and truck-loading position. Assess bucket payload, loading height and truck turnaround together. Representative loaded footage helps evaluate the proposed setup, while site production records establish the required duty. The buying case is strongest when sufficient trucks and prepared material keep the excavator productively occupied.
A configuration selected around the material
A suitable bucket and front configuration can make this machine relevant to a defined bulk excavation or quarry-loading assignment. Check material density and fragmentation before choosing bucket capacity. Review the actual bucket, boom and arm against matching technical recommendations. For dense or abrasive material, a large advertised bucket volume alone is insufficient evidence that the offered configuration fits the job.
A larger machine allocated to sustained work
A long-duration project can provide a clearer use case for a 50-ton-class excavator than a succession of small, scattered jobs. Spreading mobilisation costs across substantial
