Product Overview

The Doosan DH55 series is a world-renowned 5.5-ton compact hydraulic crawler mini excavator, widely recognized as the most reliable entry-level workhorse in the 5–6 ton small excavator segment. Built with mature Doosan Korean technology, it features a proven Isuzu diesel engine, a stable dual-pump hydraulic system and a reinforced compact chassis, delivering excellent maneuverability, low failure rate and easy maintenance. It is purpose-built for urban municipal pipeline works, landscaping, farmland renovation, indoor demolition and small-scale earthmoving projects where working space is extremely limited.

All our used DH55 excavators are sourced from formal authorized channels with 100% original core components, no structural collision or rollover history, and traceable regular maintenance records. Each unit undergoes a strict 80-point pre-delivery comprehensive inspection, including engine load test, hydraulic system pressure detection, track wear measurement and full electrical circuit verification. Purchasing this used Doosan mini excavator only costs 40%–55% of a brand-new unit, with extremely high residual value and outstanding return on investment, making it the preferred choice for small contractors, landscaping teams and individual operators.

Core Product Advantages

• Original Isuzu 4JB1 four-cylinder water-cooled naturally aspirated diesel engine, net power 40.5 kW (54.3 HP) @ 2200 rpm, proven reliability and ultra-long service life, with fuel consumption of only 3.5–5 L per hour, adaptable to low-grade diesel in various regions and continuous daily operation.

• Mature dual-pump confluence hydraulic system with simple structure, extremely low failure rate and very low maintenance cost; smooth and coordinated compound actions, suitable for various fine grading, trenching and loading operations, and easy for on-site repair without professional technicians.

• Compact body design with only 1,550 mm rear swing radius, greatly reducing collision risk when working in narrow construction sites, indoor spaces or residential areas; the 1,880 mm wide body can flexibly pass through narrow alleys and limited work zones, significantly expanding applicable project scenarios.

• Reliable digging performance: bucket breakout force reaches 31.4 kN, arm crowd force reaches 24.5 kN, matched with standard 0.175 m³ heavy-duty bucket, efficient for small-scale earth stripping, gravel loading and bulk material transportation; optional auxiliary hydraulic pipeline, compatible with hydraulic hammer, auger, grab and other attachments for multi-purpose operation.

• Reinforced heavy-duty X-shaped chassis frame with 400 mm wide steel track, strong impact resistance and excellent durability; standard front dozer blade for site leveling, backfilling and slope finishing, improving integrated operation efficiency; two-speed travel mode with maximum speed of 3.8 km/h, gradeability up to 58% (30°).

• Spacious ergonomic cab / canopy with wide field of vision, adjustable shock-absorbing seat and centralized control layout, effectively reducing operator fatigue during long working hours; equipped with safety lock lever to ensure construction safety.

• Globally recognized classic mini excavator model with abundant spare parts supply and low maintenance cost worldwide; convenient for daily repair and maintenance in various countries and regions, especially suitable for emerging markets with imperfect after-sales service system.

• Transparent and reliable used condition: genuine unmodified hour meter reading, no abnormal oil leakage from engine, hydraulic pump and control valve; no cracks, deformation or welding repair traces on boom, stick, chassis frame and revolving platform; undercarriage components maintain good wear condition.

• Full one-stop global export service: support third-party pre-shipment inspection by SGS, BV and other authoritative institutions; professional team handles customs declaration, shipping booking, container loading supervision, and provides complete set of export documents. Lifelong 24/7 online technical support for maintenance and fault troubleshooting.
